The new sand making equipment consists of various large-scale mining equipment, including vibrating feeders, jaw crushers, vibrating screens, belt conveyors and impact crushers, etc., which are widely used in various fields. Increasing the efficiency of sand and gravel production lines and reducing the cost of sand and gravel production lines has always been a concern of sand and gravel production enterprises.

Jaw crusher is an indispensable rough crushing equipment in mine crushing production line, usually used for primary crushing of materials. Its crushing ratio is large, the crushing particle size is uniform, the structure is simple, the work is reliable, the maintenance is simple, and the operating cost is economical. However, after using it for a long time, there will always be such problems.

The cone crusher has the advantages of high output and long life. It can process a variety of materials with higher hardness. All equipment is inseparable from daily maintenance and correct operation methods. We only need to pay attention to the following details to extend the cone crusher Life.

Jaw crusher is a rough crushing device, mainly used for crushing stone and ore, such as river pebbles, pebbles, granite. Jaw crusher* appeared early in 1858. It was first widely used in road construction and later in mines. It can now be used for medium-sized crushing of various ores and bulk materials. The highest compressive strength of the crushed material is 320MPa.

Preparations before the jaw crusher starts:
1. Carefully check whether the lubrication condition of the bearing is good. For the roller sand making machine, (the machine is only injected with test machine lubricant)
2. Carefully check whether all fasteners are securely fastened.
3. Whether the transmission belt is good. When there is oil on the belt or pulley, wipe it off.
4. When crushing hard materials, the feed particle size should be less than 2/3 of the inlet width.
