models have throughput capacities from 20lb to 4,000lb (9kg to 1,800kg) per hour for volumes from small samples to pilot-plant scale production. a broad range between maximum size (top size) capacity and final particle size of the processed sample means fewer steps for complete reduction.,characteristics and comparison of four types of jaw crushers,the swing jaw reciprocates in a horizontal plane, and generally the angle between fixed jaw and movable jaw is of 20 °to30°. for blake-type crusher, its feeding area is fixed while discharging area is changeable. the greatest amount of motion is at the bottom of v
feed size of the jaw crusher is 1500mm-40mm and the product size is from 50mm-5mm. rpm for jaw crusher is between 200-400. jaw crushers are heavy duty machines and hence need to be robustly constructed. the outer frame is generally made of cast iron or,engineered for the toughest feed materials nordberg® c series™ jaw crushers,the correct nip angle between the movable and fixed jaw dies ensures good bite and material flow down, even with slippery feed material. it also reduces wear on the jaw dies, reducing operating costs. with a good grip, the jaw crusher can crush rocks efficiently
an unrestricted feed opening of 1400mm by 800mm (55-inch by 32-inch) prevents bridging and maintains a consistent feed to the powerful terex wj55 single toggle jaw crusher included on this unit. the wj55 features a hydraulic closed side setting adjustment system that can be changed at the touch of a button for maximum control of product sizing.,diameter of rolls for a roll crusher for the given feed,the following formula relates the coefficient of friction (m), radius of rolls (r), radius of product (d), and radius of feed (r): cos a = (r + d) / (r + r) à 1 where a is related to the coefficient of friction by the relation, m = tan a angle of nip = 2 a we have, m = 0.29 a -1 o
and the two rolls meet to form the nip angle by simple geometry the nip angle between two rolls of radius r, the size of the particle to be crushed i.e. size of the feed ( ) and the distance between the two rolls is given by, cos θ = (2) 1,size reduction & material handling equipment - handbook of crushing,angle of nip — the angle formed between the moving surface of a crusher roll or jaw plate and the stationary plate surface at which point the material will be pinched. angle varies with machine size and material lump size. bond work index (bwi) short ton
crusher tools e.g. jaw liners are subject to numerous pressure and impact stresses. several other factors affect the wear lifetime of crusher wear parts as listed in below diagram . wear occurs in all crushers , however wear costs can be controlled by selecting the correct crusher type for,jaw crusher vs impact crusher | what's the difference |,the feed size of jaw crusher is 125mm – 750mm, which is the preferred crushing equipment for primary crushing. the feed size of the impact crusher ≤ 500mm and the compressive strength ≤ 350mpa. it is suitable for all kinds of coarse, medium and fine materials (granite, limestone, concrete, etc.).
