What is the working principle of jaw crusher?
The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.
What’s the difference between a jaw crusher and a gyratory crusher?
The gyratory crusher is mainly used for coarse crushing of various hard material in the primary crushing stage, but it is not suitable for crushing viscous ore. Jaw crusher can crush high moisture, viscous ore, and not easily blocked.
What are the functions of the intermediate crusher?
The purpose of intermediate crushing is to produce various coarser fractions or to prepare material for final crushing. If the intermediate crusher is used to make railway ballast, product quality is important.
How is jaw crusher capacity calculated?
4.4. 2 Taggart Method. The capacity of a jaw crusher is given by the amount of crushed material passing the discharge opening per unit time. This is dependent on the area of the discharge opening, the properties of the rock, moisture, crusher throw, speed, nip angle, method of feeding and the amount of size reduction.
Are employee for the operation of jaw crusher?
Detailed Solution. A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. It requires a high starting torque for their operation. Belted slip ring induction motor are employed because of their high starting torque.
What is a mantle in a gyratory crusher?

How do you size a gyratory crusher?
HOW SIZES ARE DESIGNATED The numerical size designation of Gyratory crushers represents the feed opening and the maximum diameter of the crushing head. For example, a 60-109 Gyratory crusher has a 60-inch receiving opening and an 109-inch maximum diameter crushing head.
How gyratory crusher is advantageous over to jaw crusher?
Features of the Gyratory Crusher minimizes slabbing; makes for more cubical product. Shape of receiving openings favourable for slabby material. This, plus point 2, gives the machine a distinct advantage over the jaw for handling thinly stratified stone.
What is the difference between crushing and grinding?
