In the process of sand making machine production, mechanism of sand by high fell to dump sites, in under the action of gravity, prone to segregation. According to the actual verification, the following three measures can effectively solve the problem of segregation sand making machine:
1. Playing sand adding machine discharging mouth of the conveyor belt water spray nozzle this measure besides can effectively reduce dust, mechanism of sand wet and increase the cohesion between particles, thus can effectively reduce the segregation phenomenon.
2. The mechanism of sand piled up in the process of establishing ascending type inclined pile material layer (tilt Angle should not be greater than 1:3), or create ascending type horizontal stacking layer, the mechanism of sand piled up high also shoulds not be too high (less than 5 m). This mechanism can effectively reduce the degree of segregation in the process of sand piled up.
3. In the process of mechanism sand loading and unloading, loading should be to the rectangular trunk when two piles before and after, at the same time in the first and second place in the middle of the pile. When the dump truck unloading, coarse material can be mixed and fine material again, in the case of guarantee the stability of car body, the body must be large Angle, make the material fast overall slipped backwards, can reduce material as raw material to the lateral tumble accumulation, reduce segregation phenomenon produced in the loading and unloading process.
