The crusher is designed to operate on a crank and slotted lever mechanism and the power for the electrical operation of the crusher is taken from an electrical motor. It is designed to use a 3 phase induction motor for the electrical operation of the crusher as the power required

crushers of various size as a function of the open-side set. 5.1.1 Cone crushers Cone crushers are commonly used for secondary, tertiary and quaternary crushing duties. Two variations are available - standard and short head The chief difference between cone and gyratory or jaw crushers is the nearly parallel arrangement

Impact crushers are traditionally classified to two main types: horizontal shaft impact (HSI) crushers and vertical shaft impact (VSI) crushers. These different types of impact crushers share the crushing principle, impact, to reduce the material to smaller sizes, but features, capacities and optimal applications are far from each other.

4. ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher …

– Smooth roll crusher – Serrated or toothed roll crusher Smooth roll crusher • Two heavy smooth faced roll rotating towards each other at same speed on parallel horizontal axes • Size of the material caught by the rolls depends upon the coefficient of friction between the material and the roll …

5. • Jaw Crusher • Jaw crusher is a type of crusher which produces coarse particle. • Feed size of the jaw crusher is 1500mm-40mm and the product size is from 50mm-5mm. • Compressive strength of jaw crushers is 320 mega Pascal. • Rpm for jaw crusher is between 200- 400. 6.

The actual capacity of roll crushers is only about 25% of the theoretical value due to voids between particles and loss of speed in gripping the feed particle [4], [5]. Thus the actual capacity, Q = .356 t/hr 2.1.9 Crushing Power The required crushing power is a function of Bond work index, capacity and the reduction ratio. ...

The roll crusher uses compression to crush materials. Reduction ratio is 2 to 2.5 to 1. Roller crushers are not recommended for abrasive materials. Hammer crusher. Hammer crusher consists of a high-speed, usually horizontally shaft rotor turning inside a cylindrical casing. The crusher contains a certain amount of hammers that are pinned to the ...

6.1. A smooth surfaced roll crusher had a roll diameter of 910 mm. Its suitability to crush an ore at 10.0 t/h was being examined. Preliminary examination showed that the kinetic friction factor was 0.36 when the speed of revolution was 33 rpm. The average diameter of particles fed to the crusher was 200 mm and the S.G. of the ore was 2.8.

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
