[0002] Construction solid waste sand making equipment is a kind of mechanical equipment specially used to process construction solid waste (such as waste concrete, bricks and tiles, stones, etc.) into construction sand. Its main purpose is to realize the resource utilization of construction solid waste. The produced machine-made sand can be used in multiple fields such as concrete preparation, road paving, and construction material production in construction projects, replacing natural sand, effectively alleviating the pressure of shortage of natural sand resources, and reducing the pollution of construction solid waste to the environment.

[0003] When using existing construction solid waste sand making equipment, the material feeding speed is too fast, which can easily cause a large amount of material to rush into the equipment instantly, resulting in material accumulation or local over-crushing.
