[0010] By adopting the above-described technical solution of this utility model, at least the following beneficial effects are achieved:

[0011] In use, the stone raw materials are first conveyed to the crushing and screening system through the feeding system. After being crushed by the crusher and screened into several different specifications by the vibrating screener, the mineral raw materials of several different specifications are then de-edged and dried by the de-edge drying machine. Multiple mineral stone materials of different specifications can be obtained at one time. Stone powder is obtained through the dust collection system. This is environmentally friendly and improves the utilization rate of stone raw materials, greatly improving the production efficiency of multi-specification stone.

[0012] Second, the lower end of the guide channel is connected to the feed end of the crusher. Therefore, mineral raw materials can fall into the crusher from the guide channel under the action of gravity, making it more convenient.

[0013] Third, the stone raw materials in the storage bin are sent from below the storage bin to the conveyor belt. During the conveying process, the magnetic impurities in the stone raw materials are removed by the iron remover and then sent to the feed end below the elevator. The elevator then lifts the stone raw materials to a certain height and sends them into the crusher through the guide channel. Therefore, the feeding process is convenient and efficient, further improving the production efficiency of stone.
