Failure analysis of jaw crusher and its components usin
Jaw-crusher construction. jaw crushers are heavy-duty machines and hence must be robustly constructed. the main frame is often made from cast iron or steel, connected with tie-bolts. it is commonly made in sections so that it can be transported underground for installation. modern jaw crushers may have a main frame of welded mild steel plate.
These crushers are made with jaw widths varying from about 2 to 48 and the running speed varies from about 100 to 400 rpm. • single toggle jaw crusher: the single-toggle crusher is the simplest and the lightest of the jaw crushers but is suitable only for producing low crushing forces and therefore used for jaw crusher.
