What is jaw crusher ?
Jaw crusher also known as the tiger mouth has two jaws and simulates animal movement to complete crushing of materials.The specific activities of the jaw plate works periodically close or leave the fixed jaw plate of the swing, so the material into the crushing chamber by squeezing, splitting, bending and impact the role of broken and left in less than two rows of jaw plate the mouth of the feed material discharged from the bottom of the block.
Jaw Crusher is mainly used for crushing less than 320 MPa compressive strength of various materials, a broken, broken hardware, such as ore, ore in the hard and soft ore, solvent, slag, building stone, marble and so on. Jaw crusher has a simple structure, easy to manufacture, stable operation, convenient maintenance, small size, small height, crushing ratio, even granularity, etc., is still widely used in mineral processing, construction materials, silicate and ceramic other industrial sectors, especially small and medium sized underground crushing and mobile crushing plant.
Jaw crusher can be divided into four categories.The first two jaw crushers are commonly used.
1.Jane Pendulum Jaw Crusher
Simple pendulum-type jaw crusher full name is a simple swing-type jaw crusher, the elbow plate jaw crusher. This jaw crusher work is intermittent, grinding and unloading process is carried out alternately. This crusher working principle is that all points on the moving jaw is hanging as the central axis, simply do the swing arc.
2. Compound Pendulum Jaw Crusher
Compound Pendulum Jaw Crusher full name is the complex swinging type jaw crusher, that is a single toggle jaw crusher plate. This type of crusher at work, at the same time as the swing arc up and down movement. Jaw on the trajectory of each point is more complex. Under the same conditions, the crusher capacity than the simple pendulum-type jaw crusher 20% – 30%.
3.Mixed Pendulum Jaw Crusher
Mixed Pendulum Jaw Crusher full name mixed swing-type jaw crusher. This crusher is to overcome the simple pendulum-type jaw crusher and compound pendulum jaw crusher type shortcomings development, but because its structure is more complex, easy to damage and other reasons, this crusher can not be promoted.
4. Fine Jaw Crusher
The machine is a simple pendulum, compound pendulum jaw crusher type has been improved, with a few jaw and a number of eccentric eccentric shaft structure consisting of columns, running through each jaw were crushed material, thereby reducing the machine load, and easy to start, run more smoothly, low energy consumption.
