ore can have a size of up to 400mm. There are many types of crushers but the major ones are the jaw, gyratory and the cone crusher. 2.4.1 Types of Crushers 2.4.1.1 Jaw Crusher . Jaw crushers operate by squeezing a rock particle placed between a fixed and a moving plate (jaw). Both plates could be flat or the fixed plate flat and the moving convex.
performance parameters of single toggle jaw crusher. Jaw plate wear has considerable effect on the life of jaw Crusher which is caused by the slipping motion between the fed material and the jaws. This wear is predominantly serious in the fixed plate and hence the liners of the fixed jaw should be properly chosen. In addition to this the
Crushers. Barry A. Wills, James A. Finch FRSC, FCIM, P.Eng., in Wills' Mineral Processing Technology (Eighth Edition), 2016 Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can …
A batch crusher is run at constant power input. It was found that 30 minutes of operation were necessary to reduce the average particle size from 100 mm to 10 mm. ... In a jaw crusher, feed is admitted between two jaws, a stationary jaw or anvil and a movable jaw, which reciprocates in a horizontal plane. It makes an angle of 20 - 30o
The description of crusher design is given, in which the destruction of the processed material occurs due to the forces acting on the crushed piece in the same plane towards each other, while in ...
As experience shows, when one determines the energy-power parameters of crushing and grinding processes by using the existing methods, the power of motors used in drives of existing crushers of various types often turns out to be excessive [10, 11].In this case, the drive will operate at a relatively low load (ratio of the power consumed by the …
The design has been developed for a single-roll crusher with the forced supply of destroyed material into the crushing zone [].The capture of a crushed piece occurs due to the stop located on the roll (see Fig. 1); in this case, the condition for formation of a complex stress state in the crushed piece is observed, and the energy consumption is …
industrial applications with up to 11,000 jaw crusher installations since 1975. Developed to crush the hardest ores and rocks, jaw crushers also perform outstandingly with less demanding materials. In addition to the stationary jaw crushers, many models are also available as mobile or portable versions. ® C Series™: Proven Performance

A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar: the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the …
Calculation of Reduction Ratio in Crushing ... Jaw Crusher Sizes and Power Ratings. Size is specified in terms of the gape and width, typically listed as gape x width. Largest jaw crusher is 1600 x 2514 mm with motor ratings of 250-300 kW. crushers (C200 series) are 1600 x 2514 mm with motors rated at 400 kW. ...
Jaw crushers are used mainly in first stage, primary crushing applications and are ideal for use in quarries and recycling demolition operations. ... The chassis is complete with access/maintenance platforms to the crusher and power unit and a main operator platform overlooks all stages of operation. RE model Conforms to European design ...
power PROCEDURE: • Start the jaw crusher and find the power consumption under no load condition with the help of energy meter and a stop watch. • Prepare the sample you want to crush in the jaw crusher. • Feed the above sample of coal to a jaw crusher and crush it. Measure the time for crushing.
The test determines the Bond Impact Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing crushers*. It is also used to determine the required open-side settings (jaw crushers and gyratory crushers) or closed-side settings (cone crushers) for a given product size.P80 = 25400 …
® C106™ jaw crusher shares many of the same features as other jaw crusher models in the ® C Series™. Crusher height gives a steep cavity cross-section, and the nip angle high up in the cavity, together with an aggressive well-aligned stroke at the bottom, ensure high throughput capacity and reduction.
