The jaw crusher can be described as a versatile and versatile crushing equipment, everything can be broken. Jaw crusher is the most common crusher, mainly used for primary crushing, crushable stone: limestone, quartz stone, iron ore, bluestone, river pebble, granite, basalt, shale, copper ore, steel slag , construction waste, etc. Widely used in mineral processing, coal, building materials, chemicals, refractories, metallurgy, cement, glass, ceramics, electric power and other industries. However, there are fine jaw crushers developed from traditional jaw crushers that are used as secondary crushing equipment, and impact crushers and cone crushers are common secondary crushing equipment. The fine jaw crusher has the advantages of high crushing ratio, simple structure, convenient maintenance and small investment, and is suitable for secondary crushing of various materials. However, due to the low output of a single unit, in the actual use process, multiple units are required to be installed together, which requires a lot of space, and the broken products are more in shape.

The jaw crusher is mainly composed of fixed jaw plate, movable jaw plate, frame, upper and lower guard plates, adjustment seat, movable jaw rod and other components.  Shandong kefid Co., Ltd. is an expert in the manufacture of sand and gravel aggregate production line equipment. The jaw crusher developed and manufactured by the company is a curved extrusion type: when the motor drives the belt and pulley, the movable jaw moves up and down through the eccentric shaft , when the movable jaw rises, the angle between the bracket and the movable jaw becomes larger, thereby pushing the jaw to approach the fixed jaw, and at the same time the material is crushed or chopped to achieve the purpose of splitting; when the movable jaw goes down, the The angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw leaves the fixed jaw under the action of the tie rod and the spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber.

The kefid running jaw crusher has the advantages of low noise, less dust, large crushing ratio, uniform product particle size, simple structure, reliable operation, low operating cost, safe and reliable lubrication system, convenient component replacement, simple equipment maintenance, and crushing cavity. It is deep and has no dead zone, which improves the feeding capacity and output, and saves energy of the equipment. The energy saving of a single machine is 15%~30%, and the energy saving of the system is more than doubled. The adjustment range of the discharge port is large, which can meet the requirements of different users.
