Why the Feeding Size of Sand Making Machine is Crucial?

Sand making machine is the essential equipment in sand making production line. Although there are many sand making machine manufacturer, the model is not the same, the working principle of sand making machine is mostly similar. It mainly uses "stone beat stone" and "stone beat iron" as the main crushing methods, and uses impacting and kneading to achieve the crushing effect to meet different production needs. Why the feeding size of sand making machine is so crucial? Can we feed the material in any size? The answer is no, here, we will see the detail reason.

sand making machine feeding size

Material from the hopper into the sand making machine, and is divided into two parts through the distributor. One part enters into the high rotating impeller from the middle of the distributor, being accelerated rapidly, its acceleration can be up to several hundred times of the gravitational acceleration, and then being thrown out from the three uniform passages of impeller at the speed of 60-70 - m/s. The first parts are breaking with the falling material around the distributor, then hit with the lining plate, rebounding, and oblique upward impacting to the top of vortex chamber. Changing the movement direction, falling down, and forming a continuous material curtain with the material emitted from impeller passage.

As we can see from the working principle of sand making machine, raw material, after entering into the sand making machine, it will be ejected from the impeller passage. The ejection force of impeller is certain, if the material is too large, the ejection force is poor, when strike with the materials falling from the distributor, due to insufficient force, the materials cannot be crushed to required size. If the material is too small, the ejection force is too strong to strike the freely falling material around the distributor, let alone breaking the material to the required size.

Therefore, in the production of sand making, should strictly control the size of the feeding materials, not too large or too small, otherwise, it will bring unnecessary trouble to the production.

PLS sand making machine (vertical impact crusher) developed by Luoyang Dahua, won the new product certification in 1991, especial for granite, basalt, gray green rock, and hard and medium hardness sandstone with corrosion, it has better performance in breaking and sand making.
