forced feed jaw crushers. these jaw crushers are ideal for small properties and they are of the high capacity forced feed design. on this first forced feed jaw crusher, the main frame and bumper are cast of special alloy iron and the initial cost is low. the frame is ribbed both vertically and horizontally to give maximum strength with minimum weight.
design of a crushing system that improves the crushing . a crusher is a tool or machine that is used to reduce the size of a large solid particle to a smaller solid particle the 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 241 t
equipment design jaw crushers jaw crushers consist of a rectangular frame with a fixed jaw plate and a jaw stock carrying the moving jaw. the moving jaw swings toward the fixed jaw in the forward stroke, material is crushed, and discharge takes place during the backward or freeing stroke.
opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square. generally primary jaw crushers have the square opening design, and secondary jaw crushers have rectangular opening design. jaw crushers are used as primary crushers in a mine or ore processing plant or the first step in the process of reducing rock.
the jaw crusher’s moving jaw undergoes two main types of motion, one resulting from the eccentric shaft movement, and the second from the toggle plate and the tension rod. using simulation and the discrete element method dem it is possible to model the complex crushing process in order to optimize the operation and design of the machine.
crusher design is quite a black art. i prepared over 400 crusher wear liner drawings for a client, and when you look at them, you wonder how the various shapes and profiles were ever thought up. on cone crushers, we were called in by a major quarry to help them where the crusher manufacturer could or would not.
primary jaw crushers are typically of the square opening design, and secondary jaw crushers are of the rectangular opening design. however, there are many exceptions to this general rule. a jaw crusher reduces large size rocks or ore by placing the rock into compression.
the jaw crusher’s crushing plates can be optimized, as well as the toggle plate’s motion for different applications. an overall decrease in a plant’s operating costs including electricity consumption and replacement parts can be achieved as a result of optimized jaw crusher operation and design.
