Filled in Ends – Ends can be filled in to combat the high wear area at the bottom of the stationary liner allowing liners to wear at the same rate. Crusher Wear Parts not only supplies wear parts but offers jaw liner accessories including: cheek plates, movable wedges, stationary wedges, toggle plates, and toggle seats.
Our crusher wears are available for stationary and mobile crushers, including primary gyratory crushers, ® C Series jaw crushers, HP, GP, and MP Series cone crushers, as well as for NP Series and Barmac impact crushers. We also offer wear parts for non- crushers.
A sectional view of the single-toggle type of jaw crusher is shown below. In one respect, the working principle and application of this machine are similar: the movable jaw has its maximum movement at the top of the crushing chamber, and minimum movement at the discharge point. The motion is, however, a more complex one than the …

Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double roll …
Based on the analysis of the liner movement and the crushing parameters, the normal pressure on the liner is adopted to describe the crushing force. A small experimental jaw crusher is used in the experiments, in which strain gauges and the multi-channel data collecting method are employed. With the measured results of the …
The recurrent failure of jaw-type crushing machine was traced to an inappropriate external shaft ratio and frequent wear of the jaw of the machine. Current jaw-type crushing machines are designed and … Expand
In crushers like C105 and C3055, the jaw die design on the ends is different. The lock-ing wedges on these crushers are located behind the jaw dies rather than at the top of the jaw die. Jaw dies can be allowed to wear until the thickness is 60 to 65 mm thick, or the teeth are worn flat. On other crushers the ends of the jaw dies are much thinner.
A jaw crusher consists of Crusher Body Pitman Jaw plate Rear end frame Eccentric shaft. ... Manganese liners (Jaw plate) protects the frame from wear. These include the main jaw plates covering the frame opposite the moving jaw and the cheek plates which line the sides of the crusher body within the crushing chamber. 5. …
