Stone crushing plant consists of vibrating feeder, jaw crusher, cone crusher, impact crusher, vibrating screen, belt conveyor and electric control panel etc. Its designed throughput generally is 50-600 t/h. Sand washing and other machines can be added to this line to meet the various customers’ requirements.
Jaw crusher is mainly used to crush all kinds of ores and medium-sized particles of materials Impact crusher is used in coarse crushing, intermediate crushing and fine crushing of materials like limestone, coal, calcium carbide, quartz, dolomite, sulfide iron ore, gypsum, chemical raw materials, etc.
Cone crusher improves the production capacity and crushing efficiency. It can be adopted to almost all types of materials from stone production to various ores crushing. Cone crusher can perform unparalleled crushing function in operations of coarse crushing, fine crushing and superfine crushing. Cone crushercan finely crush various ores and rocks with different high hardness, like iron ore, nonferrous metal, emery, bauxite, quartz sand, brown aluminum oxide, perlite, basalt, etc.
Stone Crushing Process
Stationary crushing plant and mobile crushing plant (portable crushing plant) are available. Stationary crushing plant has fixed plant structures. Crushing processes are as followings.
Firstly, Massive stones are evenly sent from feed bin to jaw crusher for rough crushing through vibrating feeder, then to cone crusher or impact crusher for further crushing sent by belt conveyor. Secondly, through belt conveyor, the fine crushed stones are transferred to vibrating screen for screening, so stones of different sizes will be screened out. Thirdly, the stones which meet requirement of finished products will be transferred to finished products pile, while the others will be sent back to cone crusher or impact crusher by belt conveyor for crushing again. In this way the closed-circuit cycles are formed. According to clients’ requirements, combination and classification of finished particles can be conducted.
Mobile crushing station, which is also called Portable crusher, incorporates all the equipments together on a trailer, which has high chassis, narrower body compared with other trailers. Portable crushing plant (mobile crushing plant) can be easily transported on highways and moved to crushing sites, so it is able to achieve on-site crushing without material transporting from one place to another place. In addition, Mobile crushing plant (portable crushing plant) is able to transport the final products to a truck directly. It can start to work soon even in the bumpy ground without reinstallation, so it saves more time and money than fixed crushing plant which needs to install crushing machines one by one.
Mobile crushing plant and screening plant are composed of primary crushing and screening station and secondary crushing, belt conveyor, etc. Mobile crushing station is an independent working unit, they can respectively assume their different responsibility, and the belt conveyer is responsible for material transmitting and piling up between each crushing station.
