How to improve the efficiency of sand making machine?

With the drying up of natural sand, artificial sand has been widely used in construction, highway, railway, water conservancy and other industries to replace natural sand, so the market demand of stone sand making machine is quite large. Under this background, we have developed and manufactured special stone sand making equipment. This sand making machine can process most of the stones excavated from the mountain (especially hard outside), such as limestone, Lapis lazuli, marble and so on, and eventually the finished sand can be compared with natural sand in grain shape.

Sand-making machine is different from the typical impact sand-making machine. It uses hammer to impact stone to make sand. It is commonly known as hammer sand-making machine or double-rotor sand-making machine. Customers who choose this equipment on the production line of machine-made sand have a good reaction. The advantages of this type of equipment are mainly shown in three aspects.

1. the structure is simpler and more humanized. Mainly including the chassis, hammer head, two rotors and sieve plate, etc., the sand machine is equipped with an investigation door under the turning can be readily observed equipment processing stone condition, together with easy equipment maintenance.

2. the feed size is larger. General sand machine feed size is usually about 50 mm, and the stone sand machine can allow the size of 150 mm, or even 250 mm feed. This shows that the stone between 50mm-250mm can avoid crushing process and reduce equipment investment.

3. The hammer head of the first working part is made of high hardness and good wear resistance material, which has a long service life and reduces the economic and time cost of replacing parts and directly improves the yield of customers.

Improve production efficiency of Raymond Mill

Raymond mill is one of the equipments used for grinding stone. It is widely used in many fields such as construction, building materials, chemical industry, mineral processing, metallurgy and so on. It plays an important role in improving the quality of ore. Raymond mill is usually characterized by high efficiency, low cost, easy operation, large output, low energy consumption, environmental protection and so on, which has attracted much attention and welcome in the industry.

Raymond mill as a mill equipment, to do regular maintenance, regular maintenance, attention to each small problem small hidden trouble, correct operation, in order to avoid unnecessary accidents, then how to choose lubricating grease maintenance?

1. The lubricant temperature of Raymond mill should also be paid attention to. In the use of the lean oil system of Raymond mill, we must pay attention to its return oil temperature, which should not exceed 60 degrees. The oil temperature can be controlled by adjusting the oil valve to control the flow of oil or by means of water cooling. Only in this way can we ensure the mill’s normal production.

2. The use of Raymond mill grease to consider its economic applicability, in the case of lubrication effect, as far as possible to reduce the use of grease varieties, so as to minimize the cost of production and use.

3. Where grease is used, the variety of grease to be added should be selected according to the different ways of adding grease. In Raymond mill, the roller and grinding ring are the main breaking parts of the roller bearing in this place often move, which requires timely lubrication measures. If not, the friction between the machine parts will soon be damaged. But it is important to note that the lubricant added to this place should be dry oil lubricants. Some workers will suggest that dry oil solidifies easily in winter, when a certain amount of thin oil should be added to the lubricant to avoid the lubricant solidification in the course of use can not produce the desired effect.

4. when choosing grease, pay attention to the working state of Raymond mill. The vibration intensity of Raymond mill is relatively high when it is working. The grease with high viscosity, good adhesion and good shock absorption performance should be selected when selecting grease. In this way, the use time and effect of grease will not be affected by the strong vibration force of Raymond mill.

5. The purpose of using lubricant in Raymond mill is different, which requires using grease according to different purposes. In addition, if the grease is used in a more sealed state, it should be considered whether the grease can coexist with the sealed medium.

Raymond Mill Manufacturers

Raymond Mill is a high-efficiency, high-precision milling machine that can replace the ball mill to a certain extent. Raymond mill is suitable for processing non-flammable and explosive ore with Mohs hardness below 7 and humidity below 6%, such as gypsum, talc, calcite, limestone, marble, barite, dolomite, granite, kaolin, aluminum. Bauxite, iron oxide red, iron ore, etc.

working principle:
When the Raymond mill is working, the material to be pulverized is fed into the machine from the feeding hopper on the side of the hood, and the grinding roller device suspended on the main frame of the main machine revolves around the vertical axis while rotating itself, due to the rotation. When the centrifugal force acts, the grinding roller swings outward, pressing against the grinding ring, so that the blade shovel the material to the grinding roller and the grinding ring, and the purpose of pulverizing the material is achieved by the rolling rolling of the grinding roller.

Users can adopt a variety of configurations according to the types of raw materials, sizes and requirements of finished materials. Current portable crusher plants in China are mostly used in construction waste disposal projects in urban demolition. The construction waste crushing screening is divided into several different sizes and rules of recycled aggregate, which is the basis of realizing the reuse of construction waste.

Working principle of portable crusher plant:

The material is evenly transported to the crusher by the feeder. After the initial crushing by the counter-impact crusher, the closed-circuit system is formed by the circular vibrating screen, which realizes the cyclic crushing of the material. The finished material is exported by the conveyor and is continuously crushed. The counterattack mobile crusher can remove the circular vibrating screen according to the actual production needs, and realize the primary crushing of materials directly. It is convenient and flexible to use with other crushing equipment.

Application and scope of small mobile crushing equipment:

1. Widely used in mines, coal mines, garbage and construction waste recycling, earthwork, urban infrastructure, roads or construction sites and other site operations.

2. Treatment of surface soil and other materials; separation of viscous coagulated aggregate; construction and blasting industries; screening after crushing; quarrying industry.

3. Artificial sand-making of river pebbles, mountain rocks (limestone, granite, basalt, diabase, andesite, etc.), ore tailings and debris.
