PE 400 x 600 jaw crusher does the coarse crushing process and reduce 350 mm limestone within 60mm. and then discharging output size of PF 1007 are adjusted from 10 mm to 30 mm. 3YZS1237 vibrating screen and GZD 750 x 2500 vibrating feeder are suitable auxiliary equipment in 50 t/h limestone crushing plant.

Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher, also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device .

Depending on the size reduction required, the primary jaw crushers are followed by secondary and tertiary crushing. The last crusher in the line of operation operates in closed circuit. That is, the crushed product is screened and the oversize returned to the crusher for further size reduction while the undersize is accepted as the product.

SIZE REDUCTION 2. require a small power input per unit of product 1. have a large capacity • An ideal crusher would: 3. yield a product of the single size distribution desired • cost of power is a major expense in size reduction equipment, so the factors that control this cost are important

Crushers are machines used to reduce the size of rocks, stones and ore. They are often utilized in aggregates production, construction material recycling and in mining operations.

Jaw Crushers 7 The BB 50 is designed for a very efficient and convenient size reduction pro-cess. The variable speed can be set between 550 and 950 min-1 to adapt the crushing process to sample requirements. The possibility to reverse the rotat- ing direction is helpful if too much sample material has been fed to the crusher causing it to block.

Crushers: Jaw Crusher The jaw open and close 250-400 times per minute. Mechanism: Compression Eccentric drives a pitman which is connected to two toggles among which one is connected to frame another to moving jaw. The greatest motion is at the bottom of 'V' which means there is little tendency to choke. Feed size 1.8m (6ft) in diameter.
