Features and precautions of concrete crushing machine

The concrete crushing machine is used in metallurgy, mining, construction, chemical, water and railway sectors for the medium and fine crushing of a variety of ores and rocks with compressive strength below 250Mpa. It is characterized by great crushing ratio, uniform particle size of the finished product, low power consumption and easy maintenance.

Features

1. It has a deep crushing chamber without dead zone, increasing feeding capacity and output.

2. It has great crushing ratio and uniform particle size.

3. Gasket discharge opening adjustment device is reliable and convenient; wide adjustment range increases the flexibility of the device.

4. lubrication system is safe and reliable, parts replacement is easy and equipment maintenance is simple.

5. It has simple structure, reliable operation, low operating costs.

6. large nesting population adjustment range can meet the requirements of different users.

7. It has low noise and less dust.

Vulnerable parts include toggle plate, side guard plate, fixed jaw plate, movable jaw plate, springs, bearings, V-belt and bracket pad. 

The division of jaw crusher models mainly according to the width of the feed inlet; the feed port width less than 300mm is small jaw crusher, feed port width between 300-600 is medium-sized crusher and feed port width more than 600 (including 600) is a large jaw crusher. 

Precautions

Check various parts of the fastener, especially lubricating parts and bolts, before using the machine; keep enough oil in the lubricating parts, tighten loose bolt, and then clean up the residue in crushing cavity. In the normal work, keep feeding uniform. Pay attention to the maintenance of wearing parts such as movable jaw plate, static jaw, shield and roof.
