Stone Crushing Plant

Stone crushing plant equipment introduction

Professional manufacturers of SBM provide first-class stone crushing plant and mobile stone crusher plant for sale. We provide types of crushers for ores crushing and stone crushing process that contains primary crushers, secondary crusher and tertiary crushing, the most widely used crusher machines are jaw crusher, impact crusher, cone crusher and vertical shaft impact crusher, in addition, mobile crushing plant is the portable crusher equipment for mining process of stone crushing that brings many conveniences to customers.

Professional manufacturers introduce you two crusher process flows:

Mining crushing equipment for stone crushing process is very important, it is direct decided the concentration efficiency of choosing the machines, so users should be requires careful in the selection. Stone crushing plant process generally divided into two section process flow and three sections process flow. Of course, when a big scale of dressing plant, undressed ore block is very big also, in order to reduce paragraphs crushing ratio, or to get more fine equipment granularity, also can use four part process flow.

Two process flow of stone crushing plant

Two paragraphs crushing process: two paragraphs process is divided into two sections: two paragraphs opened-circuit and two paragraphs closed-circuit. Two segments of the closed-circuit paragraph in secondary crushing machines and screening equipment into closed-circuit, this can ensure that equipment size meets the requirement, and not influence next grinding operations.

Two sections of flow only suitable for mining technology of small mining equipment, its total crushing ratio is not big, generally in 15-25. If the undressed ore block is less than 300mm, it needs not to first crush after the first screening get 75-0mm, only 300-75mm must be sent to crushing equipment. Then the stones of the first screened and the first crushed into secondary crushing together (Sieve hole for 15mm), and get the 15-0mm stones are the finally ore size and the qualified granularity. More than 15mm unqualified equipment continued to broken, until the granularity comply with requirements.

Two paragraphs opened-circuit are not very widely used, they are only applied in some heavy mining equipment of stone crushing plant, where received materials are carried into roller grinding mill. Besides, mostly stone crushing plants apply two paragraphs closed-circuit plant.

Three process flow of stone crushing plant

Three paragraphs crushing process is also divided into two sections: Three paragraphs opened-circuit and three paragraphs closed-circuit. Before the third crushing process materials can be prescreened, but also need not prescreening in the first crushing and secondary crushing process. Three paragraphs opened-circuit plant general is rarely used, because it cannot guarantee the requirement of the ultimate size. Three paragraphs closed-circuit, that means in the third paragraph of the plant, this is the most common process. It's suitable for large, medium and small dressing plant; it has a fairly large crushing ratio which can reach 25-200, the biggest feed size can reach about 1000mm, and the minimum row grain-size can be reached 12mm or more fine.
