The ore is sent into the ore receiving hopper by a truck or a loader, and a vibrating feeder is provided at the bottom of the receiving hopper to send the raw material ore into the crusher for crushing. The ore receiving hopper adopts underground or semi-underground welding type hopper, which is usually designed to be square or rectangular, the ore receiving hopper volume meets the load weight of not less than 2 ore carrying trucks due to its high structure strength, and special wear-resistant lining plate is installed on the inner wall of the hopper, fully adapting to the bulk ore unloading impact, high hardness ore impact, abrasion and other harsh conditions.

In order to adjust the production imbalance caused by the different production capacity, or for the needs of subsequent crushing process, it is necessary to set a buffer silo in front of the crusher. The buffer silo can be cylindrical or square to satisfy the 10-15min production storage time. A special wear-resistant lining plate is installed in the cone of the buffer silo to bear the abrasion of unloading ore on the cone. A bar valve is installed at the bottom of silo for cutting off the material flow during equipment maintenance. The cone angle is designed according to the material characteristics, and the pneumatic arch breaking hammer, air cannon and other anti-blocking equipment are equipped in the cone.

The finished product silo is used for the storage and distribution of finished sandstone. The storage time of the sandstone finished product silo: usually the finished product silo capacity can meet 12h production reserves. Finished product silo is circular, and can be arranged in a row. According to customers' different needs and reserves, the finished product silo can be welded steel silo, bolted steel silo or spiral steel silo. It can also be equipped with bucket elevator, belt conveyor, dust collector, bulk loading machine and other equipment according to customers' needs, to provide customers with system solutions.
