Jaw Crusher Lubrication Knowledge Analysis | 2019-09-10
Jaw crusher equipment works in different environments and requires different lubricants. In the summer, the outdoor temperature is relatively high, so you can use the No. 70 mechanical oil, while the outdoor temperature in winter is low. When the jaw crusher needs continuous work, there is a heating device in winter, which can preheat the

Analysis of the single toggle jaw crusher kinematics
Purpose – This paper aims to obtain equations that can be used to describe the motion of any given point in the swing jaw of a single toggle jaw crusher. Design/methodology/approach – The swing jaw drive mechanism of a single toggle jaw crusher is modelled as a planar crank and rocker mechanism with the swing jaw as the coupler link.

Dimensional data of a typical double-toggle jaw crusher are used in the derived mathematical expressions to demonstrate their application. Moreover, starting with the equation for the angular velocity ratio of the moveable jaw, with respect to the input crank, an expression for the ideal mechanical advantage of the crusher is derived.

Understanding comminution: Compression
Jaw crushers are generally considered a primary or first stage crusher. The maximum feed size can be as large as 80%-85% of the crusher’s gape or depth, while reduction ratios range from 2-3 times. Cone crushers are typically used in the secondary or tertiary stage after a jaw crusher’s begun the reduction process earlier in the circuit.

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.
