Flow Diagram of Crushing and Screening Process
A mobile crusher usually has a stationary steel jaw working with a moving jaw to crush and pulverise material. They are known as jaw crushers. There are also mobile cone crushers where the crushing takes place between a truncated revolving cone and an outer chamber. Free standing mobile crushing plants may be mounted on tracks, although this is not always the case. They tend to be no more than 20 metres in length, so can be used in confined spaces on small sites. These units are usually fed by rubber tyred loaders, back actors or dump trucks. Crushed material may be screened to separate two size ranges of particles, then is carried from the crusher by conveyor to be stockpiled close to the plant.
The material may be further screened either from the primary conveyor or from the stockpile; the larger material may be transferred to secondary or tertiary crushing units, screened again and stockpiled.
The screens are large sieves made of grate bars. They vibrate which causes the particles to be moved across the screen thus sorting out the particles by size. Screens can be integrated in the mobile crushing unit or can be free-standing mobile plant. They are commonly used to sort materials before crushing as well as after crushing.
Mobile crushing plant can be free-standing units or attachments to be fitted to other plant such as an excavator. The vast majority of mobile crushers are now tracked type which means they are delivered to site via low loader and can be put to work within half an hour of arriving on site.
