Five factors affecting the ability of sand making machine to produce construction sand
In the production process of machine-made sand, machine-made sand falls from a height to the stacking point, and it is easier to segregate under the action of gravity. According to actual verification, the following three measures can effectively solve the problem of sand making machine segregation.
1. Adding a water spray nozzle to the conveyor belt at the outlet of the sand blower can effectively reduce dust generation. After the machine-made sand is wetted, the cohesion between the particles is increased, which can also effectively reduce segregation.

2. In the process of stacking machine-made sand, establish a step-up inclined stacking layer (the angle of inclination should not be greater than 1:3) or establish a step-up horizontal stacking layer, and the stacking height of machine-made sand should not be too high (less than 5m). This can effectively reduce the degree of segregation during the stacking process of machine-made sand.
3. In the process of loading and unloading machine-made sand, the material should be stacked in two places before and after the rectangular car box, and in the center of the first and second places at the same time. When the dump truck is unloading, the coarse material can be mixed with the fine material again. Under the condition of ensuring the stability of the car body, the car body must be raised at a large angle to make the material slide down quickly as a whole, which can reduce the material caused by rolling off Coarse materials accumulate to the outside to reduce segregation during loading and unloading.
