Professional Manufacturer and Energy Saving Sand Making Machinery
A. sand making machinery features
1).Large handling capacity and High output—50-500t/h, the output of VSI has been stably increased 30% comparing with the traditional equipment under the same motor power.
2).Low wearing parts cost—Perfect impact angle design of the crushing cavity, less friction against the wearing parts. The operation cost reduces 40%.
3).Perfect product shape — Cubic products, suitable proportion and adjustable fineness modulus. It fits especially man-made sand and stone reshaping. The effect of making and reshaping sand has been increased 30% compared with the traditional equipment.
4).Hydraulic devices are maintained easily—Hydraulic door-opened device make the repair in the crushing cavity easily .Shorten downtime and save effort.
5).Automatic test, safe and reliable—Vibration display and warning device are set. The machine will be warned to stop working when abnormal phenomenon appears.
6).Thinning oil lubricant and automatic maintenance—The original German thinning oil lubricant station, double-pump injection system guarantees the oil supply. The machine will stop automatically when there is no oil and pressure. Water cools the oil and electric motor is heated in winter.
B. The application of sand making machinery
New sand making machine is widely used for middle and fine grinding of super hard materials such as various ores, cement, refractory materials, bauxite clinker, diamond sand, especially for grinding of building sand, stone and various metallurgical slag. It has a higher efficiency and output compared with other types of grinder
C. Working principle of sand making machinery
The materials enter the crusher through feeder hopper, which is divided into two parts by distributor, one part through the middle of distributor entering into the rotating impeller at high speed, then accelerated in impeller, whose speed can reach hundreds of acceleration of gravity, then the material is cast through the internal flow path around the impeller by the speed of 60-75 meter/second. First the materials will impact together with the part freely fallen down around distributor, then impact on the eddy current cavity’s layer together, be rebounded by layer and inclined impact to the top of the eddy current cavity, changes its direction and moves down, the materials cast from the impeller forms continual material screen.

The entire center feeding: Sand Making Machine Material falls the feed hopper, then enters the high-speed rotary sling wheel from center feeding hole, which is speeded immediately in the sling wheel. Professional Manufacturer and Energy Saving Sand Making Machinery The speed can reach several dozens times of the gravity acceleration. Then Sand making machine is thrown from the sling wheel. First, Sand Making Machine is crushed with other rebounded material fell freely from the sling wheel.

Then both of them are impacted to the material lining (rock-rock) or strike back block (rock-iron), rebounded and stroke to the Good of eddy cavity of Sand making machine in the inclined-up direction. Then Professional Manufacturer and Energy Saving Sand Making Machinery moves along deflection-down, and forms a continuous material curtain with the material from the impellers passage. Just like this, the material is stroke, rubbed, crushed twice or more, then is discharged from the down discharging hole. There is little loss for medium-sized and fine sand and stone powder. Sand Making Machine The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction. There are no other wear parts except the screen mesh. Professional Manufacturer and Energy Saving Sand Making Machinery has longer service life and little maintenance chance.
