Blake-type jaw crushers. The results of these tests were summarized in a simple first degree equation applicable to crushers using either straight or curved jaw plates. This equation first outlines the maximum capacity potential of a given crusher, then reduces this figure in accordance with installation circum-
Aggregate quality is measured in terms of product gradation, particle shape and mechanical properties. Feed gradation, crusher setting and crusher speed affects the specific energy consumption ...
A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".
( 1 ), (2) and (4), the volumetric capacity of a jaw crusher can be written as: Vh = 60N x w(S+T)/2 DT/[G-(S+T)] (5) at low speeds, and Vh = 60N x w(S+T)/2 450 g/N2 (6) = 2.645 …

Abstract: Jaw crusher is a kind of the relatively new compound pendulum jaw crusher, it has two crushing chamber and has an inverted crank rocker mechanism. The design is mainly to meet the following requirements: 1, crusher capacity 30-50t / h. 2, the maximum grain size of the material feed 120mm. 3, the largest nesting size should not exceed ...
The difference between the cumulative percentages at the 3.5″ and 1.5″ points on the curve gives us the amount, of such product to be expected from the output of the primary crusher This is 85 minus 43, or 42% of the primary crusher product. If our problem had covered a crushing condition calling for 80 instead of 85% passing the …
Denegin V V 1993 To the question of the capacity of the jaw crusher Journal of Mining Institute 138 29-31 Machines for mineral dressing, their theory, calculation and design Jan 1933
Moreover, the wear of the jaw liner profile lowers the crusher performance by affecting the shape and the overall size of the crushed particles [12, 13]. Warping and wear of the jaw plate cause a ...
18.• Single Toggle Jaw Crusher • In the single toggle jaw crushers, the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher. • The swing jaw, suspended on the eccentric, undergoes two types of motion- swing motion towards the fixed jaw due to the action of …
meanwhile the efficiency of jaw crusher become lower. So the locking angle should be constrained in a suitable interval. The transmission angle constraint condition The complex motion jaw crusher is a concrete application of four-bar mechanism, so the transmission angle decide the efficiency of the jaw crusher. If the transmission angle is small,
The capacity of the crusher is determined by its size. 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 …

Mean size of the crushed material is 0.17 meter; spec. gravity of crusher feed is 2.7 tons/cu.meter. Thus, although through different methods, both for mulas give ...
Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.
These types of crushers are usually applied as tertiary or quaternary crushers with less than 2" (75 mm) feed or smaller. Some Vertical Shaft Impactors can be used as secondary crushers with larger feed. Vertical Shaft Impactors are very application-specific. They are sensitive to abrasive materials and can experience very high …
