High manganese steel has become the leader in many kinds of crusher equipment. Since the crushing equipment is a product that often deals with stones, the material of E plate has become a key factor to check whether the Gravel crushers equipment can produce efficiently.
According to the current assembly structure of crushed stone products, usually consisting of a movable jaw plate and a fixed jaw plate, we all know that the jaw crusher’s Gravel crushers is subject to work hardening when subjected to severe impact and strong pressure deformation during use. Martensite is formed, which can form a high wear-resistant surface layer, while the inner layer maintains excellent toughness, so even if it is worn very thin, it can withstand a large impact load, so if it is to be large The crushed stone crushing production requires the overall fixing and calibration of the E plate.
Therefore, as a whole, whether it is a jaw or a counterattack, the accessories need to be calibrated as a whole, so that the quality of the whole machine can be efficiently produced later.
During the casting process, the position of the casting in the mold will affect the quality of Precision casting, dimensional accuracy and the difficulty of the forming process. The principle of selecting the pouring position: the important or main machining surface of the precision casting is facing down or side: during pouring, the gas, slag and sand in the mold will float upwards, which may form pores and slag inclusion castings The upper part. Defects such as blisters and the possibility of defects in the lower part of the casting make the tissue denser.
One. The casting position of the machine tool should be with the guide rail facing down to ensure the quality of important working surfaces. The quality of the circumferential surface is relatively high. The vertical casting scheme ensures uniform quality of the sides.
The casting of precision castings is facing down or tilted: due to the strong heat radiation of the molten metal in the upper part of the casting, the sand-like expansion arch at the top even breaks, resulting in sand, water bubbles, etc. On the big plane. defect. Large flat face down or oblique casting methods can avoid casting defects in mass production.
The thin wall of the stainless steel castings china is facing downward, sideways or inclined: In order to prevent the thin wall of the casting from being cold-separated and free of defects, a thin wall with a large area should be placed on the lower part of the casting. Cast or placed in a side or inclined position. The thickness of the precision casting should be placed on the top or side of the parting surface. The main purpose is to facilitate the feeding of risers into thick-walled sections.
The investment in machine-made sand production lines has been very encouraging recently. Its output and taste will directly affect the actual revenue of users. How to increase the output of the product while ensuring the taste of the sand is really disturbing.
As a manufacturer of machine-made VSI sand maker, we have taken over thousands of user cases, so we have integrated several common techniques, and see if there are any starting points that can optimize your production line to help you get higher Yield, better sand.
Yield increases and the taste of the finished product cannot be discounted
Ignoring the taste of sand and blindly increasing the output is not advisable. At present, construction sand has high requirements. The grit size and purity have strict parameter indicators. The quality of sand is ignored in pursuit of high yield. The obtained sand is in the market. China does not occupy a competitive advantage. The skills we have introduced to you have been verified by many users, which can not only increase the production of sand on the production line, but also give you a better taste of the sand.
Tip one: choose the right equipment
It ’s very important to choose the right equipment. Do n’t be greedy and cheap. Our sales team is in the process of user docking. Many users think that other manufacturers are cheaper. After understanding the configuration given by each other, our staff will basically Users are advised to place orders cautiously, because many small manufacturers have limited strength, in order to seize the customer base, pull down the offer, and boldly confuse users for the configuration, and some users who are new to this industry are easily confused. There are many potential problems with subsequent production lines, and once they are turned on, there will be a steady stream of trouble.
Technique two: timely maintenance
The equipment has a maintenance cycle. This is very important. The equipment of the SBM sand making machine can work continuously for about 20 hours a day, but every 4-5 hours of work, you need to stop and rest for maintenance. During the operation of the equipment, it will bear a large number of impact loads, and many minor faults, such as component wear, lubrication, etc., need to be checked after a period of work, timely replacement and maintenance if there is a problem.
Tip 3: Strictly follow operating procedures
Reasonable feeding, but no load, no-load, these are commonplace considerations, thinking that for the production line, not a piece of equipment is running, every link is well-organized, in order to maintain the orderly operation of the production line, the operating procedures are not exaggerated, When our after-sales team is serving users, we find that many users do not care about strictly abiding by the operating procedures
In the milling industry, from the initial Raymond mill to the various types of milling equipment with different functions, the reformation of the milling machine not only makes production more convenient, but also brings considerable economic benefits to users. However, no matter what type of mill, there will be dust pollution during the production process, so there is a new partner of the mill-dust collector. At present, calcite powder mills are very popular in the industry. Recently, users have questioned the dust collector effect of Calcite Powder Grinding Mill. The dust removal effect of calcite powder mills is not good. What is going on?
If the precipitator of your calcite mill is a bag filter, it may be because the filter area of the bag filter is too small and the actual air extraction volume is insufficient. It is difficult to remove the dust hood and the cavity in the discharge port of the mill. A slight negative pressure is formed, which causes larger dust; in addition, when the ground material has a high humidity (after rain or after the material is wet), the dust particles entering the dust collector are coarser than when the dry material is ground, and the bag type dust collector It is easy to paste bags, and the feeder is easy to be blocked. As a result, the ventilation resistance of the bag dust collector is greatly increased, the ventilation capacity is reduced, and the dust is serious.
During the material falling from the belt conveyor inside the calcite mill, the air and the material enter the closed dust removal hood together, and the dust-containing gas diffuses outside the hood through the gaps and orifices on the hood wall, which pollutes the environment. There is also whether the daily maintenance of the dust collector is in place. There are many failures of the bag dust collector and supporting parts. If the routine maintenance is not in place, it will not only affect the normal dust removal, but also increase the maintenance workload of the equipment.
As a responsible manufacturer of pulverizers, our calcite pulverizers will be tested again and again before delivery. If there is a problem, it will be resolved in time to ensure that the equipment arriving at the user will not have any major production problems. Of course, after using the calcite mill dust remover for a period of time, if it is not cleaned and maintained in time, the dust removal effect will definitely decline. Purchase the mill to Shanghai SBM Heavy Industry.
The reason why SBM heavy-duty sand making machine stands out among many manufacturers is that it depends on quality at the same price, price at the same quality, and after-sales at the same price and quality, and the quality and service of the sand maker It has been promoted to a certain height, and has been loved by customers for its high performance and excellent quality technology. SBM Heavy Industries has always pursued excellence to create the most perfect sand making equipment, cobblestone sand making machine, and river pebble sand making machine. , And create revenue for customers is the corporate philosophy. In the final analysis, its advantages and successes lie in the four advantages of the sand making machine.
1. Large processing capacity. The maximum throughput is 520 tons per hour with uniform particle size. Compared with the traditional equipment with the same power, the output is increased by 30% and stable. The product has a cube shape, good grain shape, reasonable gradation, adjustable fineness modulus, and is especially suitable for artificial sand and stone shaping.
2. Consumable parts with low consumption and long service life. The optimal design of the impact angle of the crushing cavity reduces the friction between the material and the wear parts, which directly reduces the use cost of the equipment. Keep the spindle bearings at a constant temperature and extend the maintenance cycle and service life.
3.Easy operation and convenient maintenance.The equipment is light weight, various installation methods, and easy to use. Once the specific purpose is clear, only minor adjustments can be made to maximize its excellent performance. Equipped with a hydraulic cover opening device to make the crushing cavity The internal parts are easy to repair and replace, saving time and effort.
4. Advanced technology The core components of energy saving and environmental protection are selected from internationally renowned brands to ensure a low failure rate of the system; the equipment has low noise and a unique air self-circulation system, which greatly reduces the amount of exhaust air and dust, which is good for environmental protection.
The increase of output and decrease of energy consumption of vertical roller mill have been the focus of attention of users of vertical roller mill. In general, the factors that affect the energy consumption of vertical grinding mainly include the particle size, moisture content, temperature, grindability, fineness of finished products and specific surface area requirements. We can reduce the energy consumption of the mill by developing and utilizing the new vertical roller mill, increasing the rotational speed of the vertical roller mill, and adding grinding AIDS in the grinding process. So as to reduce the energy consumption of the whole grinding process, reduce the production cost and improve the economic benefits. SBM small make up to help you explain how to realize the vertical roller mill energy saving and consumption reduction through these aspects of control.
- Reasonable particle size matching of grinding materials. Under normal circumstances, the maximum grinding size allowed by the vertical roller mill is 75mm, but the content exceeding 45mm should not exceed 3%, the content exceeding 25mm should be less than 15%, and the material content not exceeding 25mm should be 85%. So we must follow „. Much wear and little wear“ To ensure that the particle size before the material enters the vertical roller mill should be controlled at -25mm and 85%, so as to increase the output of the mill and reduce the energy consumption of the mill.
- Water content of raw materials. Vertical mill has drying function, which allows the water content of the materials into the mill to be controlled within 15%, while the water content of the materials out of the mill should be less than 1% to prevent the raw materials from sticking and blocking in the mill. However, heat is needed to dry the materials. The heat energy used to dry the materials to evaporate water accounts for a large proportion of the total heat. Therefore, reducing the moisture content of materials into the mill is of great help to save heat energy and improve the efficiency of the mill.
- Temperature of raw materials. The temperature control of the raw material can ensure the good grinding condition and avoid the high temperature of the raw material. If the temperature of the materials into the mill exceeds 90℃, the temperature in the vertical roller mill will generally exceed 120℃. The higher the temperature of the vertical roller mill, the stronger the static electricity generated by the product particles. The particles will gather under the adsorption of static electricity. Under the impact of the steel ball, they will stick to the steel ball and the lining plate, forming a buffer layer, resulting in a significant reduction in grinding efficiency.
- The grindability of raw materials. The wear – resistant parts of the vertical roller mill include the roller and the disc. Therefore, it is necessary to control the materials into the mill and the hardness, according to the ability of the vertical roller mill to choose the materials with the same grindability. Also pay attention to the grinding materials do not mix with non-grinding or high abrasibility of the ore, leading to wear agent wear increase or damage, can also save energy parts wear rate.
When the hammer Gravel crushers is used, the hammer head receives more than the scouring and grinding of the material. The hammer head itself bears the wear caused by the impact force, so whether it is a single-stage hammer crusher or a vertical shaft hammer crusher As long as it is used, it will withstand the impact damage required for its own work. Due to the simultaneous effects of these two aspects, over time, the hammer head will definitely wear out, and the appearance of the hammer head and the edges and corners on both sides will be gradually polished into a smooth arc.
From a professional point of view, the hammer head of the hammer crusher is abraded in this way: When the hammer crusher’s hammer head was put into production, there was no wear on the surface and the corners. The hammer head mainly received the impact force. Hit the hammer head surface with a forward force, causing the hammer head to deform and emboss. However, if the hammer head is worn out, due to the decomposition of the bearing surface of the hammer head, the reverse force of the hammer head hammer surface will impact the hammer head Force, and the tangential force exerts a cutting force on the hammer. It directly causes the Gravel crusher for sale to reduce the impact force when crushing materials, reducing production efficiency and increasing crushing time.
Therefore, when the force of the hammer head of the hammer crusher shifts and the wear effect of the hammer head changes, it indicates that the service life of the hammer head is about to end and the hammer head will fail. If you find this situation in your work, you must resolve it as soon as possible and try to avoid it in your work.
SBM-K series cement vertical roller mill is compact in structure, small in size and fully enclosed. It is mainly composed of high-efficiency powder separator, grinding roller device, grinding disk device, grinding roller hydraulic loading device, hydraulic lubrication system, reducer, motor, electrical and other parts . The separator is an efficient and energy-saving powder selection device. The combined conical grinding roller is a component used for crushing and crushing materials. The grinding disc is fixed on the output shaft of the reducer, where the grinding rollers roll the material. The hydraulic loading device is a component that provides grinding pressure to the grinding roller, and provides sufficient pressure to the grinding roller to crush the material.
The motor of the vertical roller mill drives the grinding disc to rotate through the reducer, and the material falls from the feeding port to the center of the grinding disc. Under the action of centrifugal force, it moves to the edge of the grinding disc and is crushed by the grinding roller. The crushed material overflows from the edge of the grinding disc and is Nozzle ring (air ring) high-speed upward hot air flow is brought into the high-efficiency powder separator integrated with the vertical roller mill. After the coarse powder is sorted by the separator, it is returned to the grinding disc and re-milled; the fine powder is milled with the air flow. Collected in the system’s dust collection device, it is the product. Coarse particles and metal parts that have not been carried by the hot air flow fall from the wind ring, are scraped out by the scraper, and then fed into the mill by the outer-circulating bucket elevator to be ground again.
SBM-K cement vertical roller mill is a new type of vertical roller mill developed by our company for the final grinding process of cement clinker. It integrates grinding, drying and classification. Compared with traditional mills, its great advantage is that Low energy consumption: The average power consumption is less than 30kwh / t.

SBM-K cement vertical roller mills have various varieties and complete specifications. According to different project scales, they can meet the production needs of 1000-7000 tons of cement clinker per day.
The vertical roller mill is mainly used for the grinding of cement raw materials, and the dust is conceivable. If it is not cleaned for a long time, it will lead to insensitive parts and components, and over time, it will cause blockage of some parts. Therefore, it is necessary to clean the vertical roller mill once in a timely manner.
The vertical roller mill is a relatively large machine. How to clean it is also a headache. SBM Heavy Machinery has given some suggestions based on more than 50 years of research and production experience.
- For small parts, we can adopt manual cleaning. Parts can be removed and placed in diesel, kerosene or other cleaning liquids. Manual cleaning is performed with tools. Of course, this applies only to small parts.
- For the parts with complicated structure, manual cleaning is not very convenient. We can use spray cleaning method, spray water pipes or other tools to clean it, and the effect is very good.
- For components with more complicated structures, cleaning equipment can be used for cleaning. Generally, different cleaning liquids are used to perform operations according to the principles of ultrasonic and vibration cleaning.
In general, the cleaning of the vertical roller mill should be combined with the actual conditions, and different cleaning methods should be adopted according to the different levels of different parts of the dust. SBM Heavy Machinery recommends that everyone clean the vertical roller mill before assembly to ensure The machine has a better working efficiency
