What equipment is needed to build a gravel plant? How much does it cost to build a stone factory? People who come into contact with the industry for the first time are very interested in this. With the development of economy, the urgent demand for sand and gravel aggregate in the market is also increasing, and the upsurge of investment in building stone plants and sand and gravel plants is also rising.
Driven policy of expanding domestic demand, the investment in infrastructure construction such as roads and railways is increasing day by day. The effective development of large-scale projects urgently needs a large amount of sand and gravel aggregate supply. Natural sand and gravel aggregate is always limited, and excavation and mining will cause serious ecological damage to the environment. In order to protect the ecological balance, the state expressly prohibits the unauthorized excavation of natural sand. The supply of sand and stone is far from keeping up with the demand, which requires a large amount of artificial sand.
In the production of sand and gravel aggregate, sand making equipment is mainly used. The raw materials mainly include granite, limestone, basalt, cobble and other stones with certain hardness, which are crushed and screened by a series of equipment such as feeder, jaw crusher, reverse impact crusher, sand making machine, vibrating screen and so on.
In addition to considering the local geographical environment, raw material sources, production sites and other factors, the investment in the stone factory and gravel factory needs to consider what equipment is needed to build the factory, how to select the equipment, and how to be more economical and reasonable. Here, we give a brief introduction, the complete set of quarry equipment includes: feeder, jaw crusher, impact crusher, vibrating screen, etc. The more reasonable equipment type and model are determined according to the user's stone characteristics, purpose and site size. Different equipment targets different raw materials. Therefore, the actual situation of raw materials shall be informed to the technicians for specific type selection, and the technicians shall put forward suggestions and type selection.
Crushing steps: firstly, the stones are uniformly sent to the coarse crusher by the feeder for preliminary crushing, and then the produced coarse materials are transported to the impact crusher by the belt conveyor for further crushing. The finely crushed stones are sent to the vibrating screen to screen out stones of different specifications. The stones that meet the particle size requirements are sent to the finished material pile by the finished product belt conveyor, and the stones that do not meet the particle size requirements are returned to the impact crusher for crushing again, Closed circuit multiple cycles are formed. The particle size of finished products can be combined and classified according to the needs of users. In order to protect the environment, auxiliary dust removal equipment can be equipped.
