Primary and Secondary Stone Crushing Plant Used in Gold Ore Crushing Dressing Plant
Professional manufacturer of LIPU provide first-class stone crusher 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.
Process Flows of Stone Crusher Plant
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 Crusher 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 15m
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.
