After it is dismantled, you need to cut down the rare lubrication oil and cooling water pipe. By way of supporting it with a frame on the bottom of the rod, you are able to unsnatch the cap and lift it out. Jaw breaking machine is widely used in the world nowadays and has the features of high reduction ratio, uniform granularities, simple structure and easy maintenance. It has two types: primary and secondary crusher. The compressive strength of the final products is up to 320MPa.This series of breaker of large and medium-size are the key products of our company. And our company takes the leading place in designing and producing large jaw crushers in China. This series of products have the advantages of big reduction ratio, even granularity, simple structure, liable operation, easy maintenance, economic operation cost, etc. It is widely used for materials with the max crushing compressive strength not more than 320Mpa in the field of mine, metallurgy, building materials, roads, railways, irrigation, chemical industry, etc. The spindle should and pulley crusher and the flywheel took together. The motor (along with the belt) along the slippery course as far as possible to crusher moved in, take off the triangle leather belt. And then the shaft crane mentioned. In order to remove the dynamic jaw, must first cut off oil lubricating oil tube dry, remove the bars, and take bearing cover, then use crane or other ascending equipment will move jaw pull out. What is its operational principle? When it is operated, it is driven by motor through belt and belt wheels, which makes the movable jaw plate up and down through eccentric shaft. When the movable jaw comes down, the angle between the fixed jaw plate and the movable jaw plate gets smaller, Then the materials can be crushed. When the movable jaw plate rises, the angle becomes larger and the movable jaw plate leaves the fixed jaw plate with the function of tie bar and spring. At the same time the final products are discharged from the lower outlet of the crushing chamber. jaw crusher: http://www.hxjqchina.com/product-list_11.html jaw crushers: http://www.crusher-machine.com/1.html Sand washing plant: http://www.hxjq-crusher.com/16.html
