VSI Sand Making Machine


The machine is mainly applied to all kinds of ores, cement, refractories,bauxite,carborundum, glass raw materials, building sand, construction, aggregate, artificial sand and operation of fine and coarse grinding. Especially for silicon carbide, corundum, sintered bauxite,US-sand high hard, hard and abrasion resistance material, its production is higher than other similar types of production.

Material are divided into two parts by the distributor, when it from the hopper into the impact chamber.


1, unique Liu riveting technology to increase the body's strength and toughness, effectively reduce the machine resonance.
2, hydraulic maintenance arm, greatly reducing maintenance costs.
3, a variety of broken way to meet the needs of different materials broken.
4, the use of imported bearings to ensure stable operation of the machine.
5, dual-pump design, the normal use of only one pump work, only in the pressure, the flow can not reach the set value, the second work, or the first oil pump failure, the second automatically open to To ensure the normal operation of the host.
6, the bearing bit temperature, as long as the cabinet has electricity, oil temperature to ensure that more than 15 ℃, oil temperature above 50 ℃, the external water supply system (user-owned) automatically work until below 50 ℃, if the oil Temperature for 15 minutes higher than 70 ℃, it is necessary to send a shutdown signal to the host. If the oil temperature is below 15 ℃, the heater will automatically heat and the oil pump will automatically work for 5 minutes to ensure that the temperature in the bearing cylinder is close to the oil temperature in the tank and prevent the winter from freezing.
7, the new impeller design, optimize the flow of materials, the same power than the old equipment output 30% higher.

working principle

Material from the hopper into the sand machine, the material will be divided into two parts by the distributor, part of the feeder into the middle of the high-speed rotation of the impeller, the rapid acceleration in the impeller, the acceleration up to hundreds of times the acceleration of gravity, And then at 60-70 m / s from the impeller three uniform flow of the projectile out, first with the distributor around the self-falling part of the material impact crushing, and then hit the vortex chamber on the material lining , By the material lining rebound, oblique impact to the top of the vortex cavity, but also to change its movement direction, deflecting downward movement, from the impeller flow out of the material to form a continuous material curtain. Such a piece of material in the vortex crushing chamber by two times as many times the probability of impact, friction and grinding crushing effect. The broken material is discharged from the lower discharge port. In the whole crushing process, the material is self-impact crushing, not in direct contact with the metal components, but with the material lining impact, friction and crushing, which reduces the angle of pollution, to extend the mechanical wear time. Vortex cavity inside the clever air from the cycle, eliminating the dust pollution.
