Our EV Hammer Impact Crusher, however, competently reduces quarry-size line boulders measuring up to 2.5 metres and weighing up to 5 tonnes to mill feed of 25 millimetres. This is a reduction ratio of 1:100 in a single operation.
Note: The capacity is total tons per hour passing through crusher at open circuit when crushing medium and low hardness materials with the bulk density of 1.6x10³kg/m³. Capacity is relative to physical character, feeding type, feeding size, composition, etc.
Rock Particle Breakage in Impact Crushing. where W = work in KWH/short ton Wi = Work Index F80 = 80 percent passing size of the feed (micrometers) P80 = 80 percent passing size of the product (micrometers) The Work Index for rod and ball mills can be determined from laboratory tests and, as demonstrated by Rowland,.

The numbers used in referring to jaw crushers, such as 3042, refer to the opening size at the top of the jaw. The 30 is 30" left to right, the 42 is 42" across the jaw. Allowable top size is approximately 80 percent of the left-right dimension, or in this case, 24".
These rugged, single rotor, primary impact crushers are made for high capacity, high reduction ratio, plus external product size adjustment. Willpactors® are engineered around four rotor sizes to provide capacities as high as 1700 tons per hour.
Impact crushers involve the use of impact rather than pressure to crush material. The material is contained within a cage, with openings on the bottom, end, or side of the desired size to allow pulverized material to escape.
The gape determines the maximum size of material that can be accepted. Maximum size that can be accepted into the crusher is approximately 80% of the gape. Jaw crushers are operated to produce a size reduction ratio between 4:1 and 9:1. Gyratory crushers can produce size reduction ratios over a somewhat larger range of 3:1 to 10:1.
Impact crusher is suitable for materials whose compressive strength is under 350Mpa, and particle size is less than 500mm. With end products in cubic shape, the impact crusher is widely used for sand and rock producing in the industry of roads, railways, reservoir, electricity power and …
How to Evaluate/Estimate a Crusher Product Size (9 replies) Note that it may be a challenge to get the ball (s) down the pocket, over the material and through the widest part of the opening, which may be poorly accessibility (on the far side, under a spider arm etc).
