Crusher, generally refers to the machine used for crushing stone, metal ore, construction debris, ordinary jaw crusher, used for primary crushing (large stone condition), impact crusher, cone crusher for secondary crushing (small and fine stone condition), vertical shaft hedge crushing (fine sand condition). crushers are mainly used for crushing stones, mines and providing raw aggregates for production!

What is the function of a single toggle jaw crusher?

The up and down movement of the jaw crusher motorized jaw plate with a toggle lever can promote the discharge, and the horizontal stroke of the upper part is greater than that of the lower part, which allows large materials to be easily crushed. therefore, its crushing efficiency is higher than that of the double gag type. The disadvantage is that the jaw plate wears out quickly and the material is crushed too much, which increases energy consumption. To protect the important parts of the machine from damage caused by overload, the toggle plate with simple shape and small size is often designed as a weak link, so that it deforms or breaks first when overloading the machine.

In order to meet the requirements of different discharge granularity and compensate for the wear of the jaw plate, an adjustment device for the discharge opening is also added, usually an adjustment disc or wedge iron is placed between the seat of the toggle plate and the back frame. However, in order not to interfere with production by replacing defective parts, hydraulic devices for securing and adjusting can also be used. Some jaw crushers also directly use a hydraulic transmission to drive the movable jaw plate to complete the crushing effect of the material. These two types of hydraulic power transmission jaw crushers are often referred to collectively as hydraulic jaw crushers.


What is the crushing method of the jaw crusher?

The crushing process of jaw crusher is the bent extrusion type.

The jaw crusher is a motor driven belt and pulley, and the movable jaw moves up and down through the eccentric shaft. As the movable jaw lifts, the angle between the toggle plate and the movable jaw becomes larger, pushing the movable jaw plate to approach the fixed jaw plate, and the material is crushed or crushed to achieve crushing. Purpose: When the movable jaw goes down, the angle between the toggle plate and the movable jaw becomes smaller, the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring, and the crushed materials are discharged from the lower opening of the crushing cavity.


What should be considered when using the crusher?

(1) Pay attention to any unusual impact sounds inside;

(2) Whether the machine is running smoothly and whether stones are entering and discharging smoothly;

(3) The operation of the oil pump, the oil flow indicator at each point, whether the oil temperature and oil pressure are normal.
