Stone crusher for quarry in Japan

Stone crusher for quarrying in Japan

Stone crusher is a quarry machine used for manufacturing crushed stones, which are raw material for various construction  activities i.e. construction of roads, bridges, buildings and canals.

Jaw crusher for stone quarry in Japan

Jaw crusher is a coarse crushing equipment widely used in stone quarrying and mining industry in Japan. Gyratory and jaw crushers represent the bulk of primary crushers used at mining operations today. In some stone mine, roll impact crushers, low-speed roll sizers and feeder breakers are also used in primary crushing process.

Jaw crusher has different output, which depends on the types used in the complete stone crushing plant. Small or mini jaw crusher is used in small scale stone crushing plant or mine ore mining processing project with 20-30 tonnes per hour. Large jaw crusher is a heavy duty crusher machine used in large stone quarrying business, aggregate sand production line, or mine ore mining plant in Japan.

Impact crusher for stone quarry in Japan

Impact crusher is a fine crusher machine. Usually it is widely used in sand gravel production line. The major equipment in a primary crushing circuit usually includes only a crusher, feeder and conveyor.

Impact crusher crush stones the Impactor or Impact Breaker or double impeller breaker. Rock fed into the breaker falls directly on to the impellers (which weigh up to 6.5 tons) and rotate away from each other, turning up and outward, at speeds from 250 to 1000 rpm depending on the desired size of finished product.

Cone crusher for stone quarry in Japan

Cone crushers remain the most popular for fine crushing applications, although some mines use vertical impact crushers for tertiary and quaternary crushing. The shallow cone crushers are mainly used for the fine crushing of hard and moderately hard materials.

Secondary and tertiary crushing circuits have the basic equipment items, along with screens and surge storage bins. Cone crusher is a Gyratory Crusher, where the crushing action takes place around the cone.

Hammer crusher for stone quarry in Japan

Hammer crusher is a grinding mill, these crushers are simpler than jaw and cone crushers and units with equivalent throughput are much smaller in size. Huge hammer crushers with rotor diameters up to 3 m are available which have throughput of even 1500T/hr. Although hammer crushers wear more quickly than impact crushers, they can process moist materials more efficiently.

The choice of stone crusher depends on the type and amount of material to be crushed. Raw stone could be purchased directly from the excavator (quarry lease holder) or crusher may hold his own quarry lease to produce raw stone. The crushed stone is screened to separate  the produce in different sizes by the separator.

The main machinery involved in the stone crushing industry is Hammer Crusher, Screen, Conveyers etc. The process involved is to feed the stone in to the Hammer Crushers to make it further smaller in size as required by the customer. The crushed stone is conveyed by the conveyors to trucks for transport to the market place or storage area.
