Adjusting the optimum impact velocity of the impact sanding machine

Now the market sanding machine is divided into different types according to the different production methods, such as the impact making machine we often use. Customers choose the sand making machine that is suitable for their needs according to the requirements of hardness, humidity and finished product’s grain type output. It is particularly important to choose a suitable sand making machine, which is directly related to the direct interests of our production requirements.

The crushing energy of impact sand making machine is converted from the impact energy of the material, and the impact energy is directly proportional to the velocity squared of material movement, and the wear speed of wear resistant parts is directly proportional to the square of the velocity of material. That is, the higher the crushing velocity of the material is, the higher the fineness will be obtained after the crushing. However, every material has the best impact speed. When it exceeds this speed, the utilization rate of crushing energy will obviously decrease, and at the same time, the equipment will wear rapidly, which will seriously affect the normal use of the equipment.

Therefore, through the analysis of the production process and the analysis of the customers in the field, SBM analyzes the experiment, again and again, to find out the most suitable material crushing impact speed, so that the customer can get the maximum output and the lowest energy consumption in the process of using. So, when the customer buys the machine, please read the product instructions carefully or call our sales hotline directly. So that there is any problem and can be solved for you at any time.

Remote control of counterattack sand making machine

The counter-attack sand making machine is also a commonly used crusher for sand mills and stone factories. With the rapid development of science and technology, machinery will further enter the high-end and automation. The remote control of the counterattack sanding machine is a good example.

What are the remote control of the sand making machine? Main transmission, lubrication, temperature detection and discharge mouth adjustment are all remote control. These controls can be implemented by a control cabinet equipped with a signal system that reflects the normal working index of the crusher, its diagnosis and the state of the accident.

The crusher control can also be realized from the central console of the control process. At this time, the necessary information on each system function of each crusher is input to the console so that the work of the crusher and production line can be adjusted quickly. The remote control of the crusher can set up the crusher on the automatic production line without the need to manually control a single crusher in the broken section. In this case, the crusher is equipped with a microprocessor control system (automatic control system). It controls and detects all the main process parameters and parameters of the crusher by means of computer control.

To solve the problem of wear of sand machine under high strength operation

Sand equipment every day to face the hard stone, what kind of different hardness of stone are need to be uniform in particle sand and gravel sand making machine work, and the Russian version of the plate hammer so sand making machine will have different degrees of wear, problems need to be handled in a timely manner or change.

To solve the wear problem of sand making machine under high intensity operation, aiming at such a heavy task amount of sand making equipment, the problem of weight and resistance is the key to optimize the operation of sand making machine, and the decompression control of the equipment can make the sand making machine more efficient in production. Any equipment is developing in the perfect direction, the quality of the product and the continuous transformation of production technology can ensure the stable and efficient production of the sand making machine.

How to clean the sand making machine

Here are some ways to remove the rust on the surface of the sand making machine.

1. Small wind or electric rust removal. Mainly electric or compressed air as the power, the assembly of appropriate rust removing device, reciprocating motion or rotation movement, in order to meet the requirements of various occasions of rust removal. As the angle grinder, wire brush, pneumatic needle beam device, pneumatic derusting and chipping hammers, tooth type rotary descaling device, which belongs to the semi mechanized equipment, light weight, high flexibility, can thoroughly remove rust, old coating, the coating for wool processing, greatly improve the efficiency than manual derusting. Up to 1~2m2/h, but cannot remove the oxide skin, the surface roughness is small, cannot achieve high-quality surface treatment quality, work efficiency is low injection processing. It can be used in any part, especially in the process of ship repair.

2, shot peening (sand) rust removal. It is mainly composed of particle spray erosion to achieve surface cleaning and proper roughness. The equipment includes open shot blasting (sand) rust remover, closed shot blasting (sand chamber) and vacuum shot blasting machine. The open shot blasting machine is widely applied, which can completely remove all impurities on the metal surface, such as oxide scale, rust and old paint film. The rust removal efficiency is high 4~5m2/h, the mechanical degree is high, and the rust removal quality is good. But because the abrasive generally can not be recycled, the other work has an impact, cleaning up the scene trouble. Therefore, the environmental pollution is heavy and has been gradually restricted to use recently.

3, high pressure water abrasive rust removal. The impact of high pressure water jet (added abrasive grinding action) and water prying action destroy the corrosion and adhesion of the coating to the steel plate. It is characterized by no dust pollution, no damage to the steel plate, greatly improving the efficiency of rust removal, up to 15m2/h, and the quality of rust removal is good. However, the steel plate after rust removal is easy to return to rust and must be coated with a special wet rust removing coating, which has a great influence on the coating of general performance coatings.

4, shot removing rust. Blasting is the use of high-speed rotation of the impeller will be thrown to the abrasive surface of steel to achieve the purpose of rust removing, is a kind of advanced treatment method of mechanical rust for hull steel material, not only high production efficiency, low cost, and high degree of automation, can realize the pipeline operation, less environmental pollution, but only in the operating room.

5, chemical rust removal is mainly based on the chemical reaction of acids and metal oxides, so as to remove the rust removing method of the corrosion products on the metal surface of the sand making machine, which is usually called acid pickling and rust removal, and it can only be operated in the workshop.

A impactor crusher crush hard river rock

Impact crusher, also known as sand making machine, vertical impact crusher by feeding, distributor, vortex dynamic crushing cavity, experience the impeller, spindle assembly, base drive device and electric motors is composed of seven parts.

SBM’s impact crusher is widely used in all kinds of metal and non-metallic minerals, cement, refractories, abrasive, glass raw materials, building aggregate, mechanism sand, metallurgy and other industries. Suitable for crushing different hardness of various minerals and rocks, such as iron ore, non-ferrous metal ore, carborundum, bauxite, quartz sand, corundum, perlite, basalt in high hardness materials finely homework is the core equipment in the domestic construction, mining, metallurgy industry and highways, railways, bridges, water and electricity, mineral grinding area and the mechanism of sand industry.

Impact crusher in terms of its working principle, a simple point is that the principle of stone stone. Let the stone in the natural fall process and through the impeller to speed up the stone thrown out of the collision, so as to achieve the purpose of breaking. And was accelerated by the fall of the stone and natural stones fall into a vortex, the return process and the two broken, so in the process of running the machine on the impact of the board is very little.

Countermeasures for running fault of counterattack crusher

The quality of the 1 plate hammer bolts is poor, because the quality of the bolts is poor, often loosening and breaking, causing the hammer to loose, fall off or break.

The quality of the 2. plate hammer is made of the high manganese steel, which is seen from the fracture, and the pores and even holes are visible, and the structure is larger, and the quality of the casting and heat treatment is poor.

3. improper use and maintenance, because the plate hammer is often broken, the operator’s workload is larger and the labor intensity is larger. Therefore, after the new board hammer is installed, it is lazy to stop the machine to check, so that the loosening of the bolt can not be fastened in time.


(1) remanufacture the bolt mold, so that the elliptical head of the bolt and the contact surface of the screw hole of the board can be in good contact. At the same time, the thickness of the screw thread teeth is controlled in the size allowance, and the unloading groove is processed to prevent the stress concentration from breaking.

(2) in view of the quality problem of plate hammer, our factory used the plate hammer of the original crusher factory, basically met the quality requirement.

(3) strengthen the management of use and maintenance. First, when the plate hammer is installed, the plate hammer hole and the sands and burrs of the slot must be removed to make the connection smooth. Secondly, when the fastening plate is bolt, the ellipsoid head should be hammered by the fastening edge; then, the bolt fastening situation should be checked in time for about half an hour after operation, and then the nut and the thread are welded to prevent loosening.

Four major models of mining machinery crusher.

In industrial production, the crusher is widely used, many varieties, but the most commonly used crushing equipment called these four kinds of equipment. The four series of jaw crusher, cone crusher, counterattack crusher and impact crusher. The four crusher is a typical example of the crusher. This crusher basically can meet all kinds of sand production, stone crushing, and making and milling needs. Next, SBM will analyze the different characteristics of the four crushers in detail for you.

First, jaw crusher is often used in coarse crushing equipment, can also be used in medium, large intake, simple principle, very wide reference. But it is extruded and broken, and there are many needle flakes. Therefore, in the production of stone, the jaw crusher cannot be used as the final molding equipment.

Two, cone crusher is an efficient crusher equipment, is also commonly used equipment in stone production, cone crusher is a combination of extrusion, splitting, collision equipment, material forming lamination, so it is broken than lamination. There will be a certain amount of needle-like production, but much less than the jaw crusher. Cone crusher has a long life, stable operation, environmental protection, energy saving, high production efficiency and convenient maintenance. Because of these advantages, the overall price of cone crusher will be higher than that of other crushers.

Three, counter crushers rely on plate hammer and counterattack plate to crash impact on materials. The lowest content of needle flake is the most suitable for the production of standard coarse aggregate, but the crusher is bigger in crushing and hard material than in other crushing crushers.

Four, impact crusher, impact crusher is mainly used for making full use of sand, rock stone, stone timber wolves, high production efficiency, the mechanism of sand like sand smooth, and more slender, when needed can produce a sand powder.

SBM has rich experience in the design of gravel equipment and sand production line. Combined with the excellent performance-price ratio of our crusher, it has laid an impact on our sand and stone equipment industry. Our company’s lithotripsy line has the lowest price. The technical personnel can be very good at the grain type produced by each equipment, and the designed production line can make the customer satisfied with the output and shape.
