product description


High-efficiency sand making machine is particularly suitable for the crushing of soft or medium hard and extremely hard materials, especially the S series sand making machine is widely used in various ore, cement, refractory materials, bauxite, clinker, glass raw materials, mechanisms Building materials, gold slag, silicon carbide, sand and other hard, ultra-hard and wear-resistant materials. It is 50% more energy-saving than traditional fine crushers, and it is the world's most advanced new sand making equipment.

Advantages of efficient sand making machine


1. Unique rotor and cavity design.

Second, the sand formation rate is high, the product grain shape is good.

Third, the processing capacity is large, and the dust dispersion is reduced.

Fourth, the self-lifting system makes maintenance more convenient.

Fifth, the motor base elastic reinforcement device, the operation is more stable.

working principle


The material enters the high-efficiency sand making machine from the feeding hopper, and is divided into two parts by the distributor. One part enters the high-speed rotating impeller from the middle of the distributor, and is rapidly accelerated in the impeller, and its acceleration can reach hundreds of times the acceleration of gravity. Then, at a speed of 60-70 m / s, it is ejected from the three uniformly-distributed runners of the impeller. First, it is crushed with a portion of the material falling around the distributor, and then impacts the material lining in the vortex branch cavity. It is rebounded by the material lining and impacts obliquely upward to the top of the vortex cavity, and then changes its direction of movement, deflects downward, and the material emitted from the impeller flow channel forms a continuous material curtain.

basic structure


It is mainly composed of nine major components such as the feeding hopper, the distributor, the vortex crushing cavity, the impeller, the main shaft, the base, the transmission device, the support, and the lubrication system.

Wear parts of sand making machine


Whether the wearing parts of high-efficiency sand making machine is durable is one of the important considerations for customers when choosing sand making machine. How to ensure that the wearing parts of sand making machine are efficient, wear-resistant and have low maintenance rate, Shanghai Weili Road & Bridge has its own uniqueness in this regard. Insights. First, the easy-wearing parts are cast with special hard and wear-resistant materials. The sand making machine parts produced in this way are small in size, light in weight, wear-resistant and easy to replace. Second, the hardness and viscosity of the crushed materials are also obvious to damage the vulnerable parts. As long as the crushed material is within the specified hardness and viscosity range, the consumables can ensure their service life. Finally, the rationality of the overall structure of the sand making machine must be ensured. Stable, wear on consumables can also be greatly reduced.

Technical maintenance


1. Periodically shut down and open the observation door to observe the internal wear of the sand making machine. The degree of wear of the central feeding pipe, cone cap, impeller upper and lower runner linings, circumferential guards and wear blocks should be replaced or repaired in time after wear. The wear blocks should be replaced at the same time to ensure that the wear blocks have the same weight. It is strictly prohibited to open the observation door to observe the internal working conditions during the work of the high-efficiency sand making machine to avoid danger. If the impeller body is found to be worn out, replace it with a manufacturer and repair it in time. In particular, without the manufacturer's consent, it is strictly forbidden to make the impeller without permission, otherwise you will bear the consequences.
2. The high-efficiency sand making machine adopts Mobil vehicle grease special grade or 3 # lithium base grease, add the appropriate amount of grease every 400 hours of work, open the spindle assembly to clean the bearings after 2000 hours of work, and generally work for 7200 hours, replace the new bearings. The upper end bearing of the main shaft assembly is the floating end, and the lower end bearing is the fixed end. After assembly, the belt pulley should be turned flexibly by hand.
3. The tension of the transmission triangle tape should be adjusted appropriately to ensure that the triangle tape is evenly stressed. When driven by dual motors, the triangle tape on both sides should be selected and matched so that the length of each group is as consistent as possible. Should be adjusted so that the current difference between the two motors does not exceed 15A.
4. In the operation of high-efficiency sand making machine, because the equipment is a high-speed equipment, special attention should be paid to safe production. Relevant personnel should stay away from the equipment and repairs should be performed after shutdown.
