Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

Primary, secondary, and tertiary crushing are three stages in the comminution process that break down large rocks into smaller pieces of varying sizes. Each stage uses different types of crushers and has distinct advantages and disadvantages. This article provides a comprehensive guide to primary, secondary, and tertiary crushing.

Abstract. It is well known and taken for granted that the efficiency of energy use by comminution (i.e. breaking, crushing, grinding) equipment is very low, typically less than 10%. Most of the process input power is dissipated as heat and noise and ineffective deformation of the material to be processed and the device itself.

Jaw crusher is used as primary crusher, it's reduction ratio is usually 6:1. It uses compressive force to break the material, this mechanical pressure is achieved by the two jaws of the crusher. It is called a jaw crusher because it works the same was a human jaw does-food goes into your mouth and your bottom jaw pushes the food up against ...

Where is A Jaw Crusher Used for ？ A jaw crusher is primarily used in the initial stage of the crushing process.
Details
Using electrodes you can only deposit a limited amount of weld per minute. Using a wire feeder you can possibly go up to anything like 4 times the amount of weld metal. Based on that then more weld metal deposited equals more heat. Heat could be the root cause of the warpage, therefore it makes sense.
