The fine jaw crusher is called fine jaw crusher or fine crusher. It is a jaw crusher with a relatively small crushing cavity. Generally, the crushed material is uniform. The fine jaw crusher is a kind of rock crusher, which is mainly used for fine-crushing operations.
The crushing cavity is deep and there is no dead zone, which improves the feeding capacity and output. The crushing ratio is large and the product particle size is uniform.
Simple structure, reliable operation, low operating costs, 15% to 30% energy saving for a single machine, and more than double the energy saving for the system.
Gasket-type discharge opening adjustment device is reliable and convenient, with an extensive adjustment range, which increases the flexibility of the equipment, the lubrication system is safe and reliable, the parts are easy to replace, and the maintenance workload is small.

Similar to the medium and primary crushers, it is mainly composed of a frame, movable jaw, eccentric shaft, fixed jaw, movable jaw, toggle plate, adjustment seat, and other parts. The motor drives the eccentric shaft through the V-belt through the grooved wheel. , so that the movable jaw reciprocates to crush the materials entering the crushing cavity, and the materials are discharged from the discharge port by their weight.
jaw plate can be exchanged up and down: the fixed jaw plate is fastened on the front wall of the frame by the compression bolt, and the movable jaw plate is pressed on the movable jaw plate by the bead. When the jaw plate is worn (usually the lower end is more worn), the two Those who can change the position, continue to use it.
Protection function: In addition to supporting the movable jaw to make it run according to a certain axis, the toggle plate also plays an insurance role when foreign objects that cannot be broken enter into the crushing cavity and the load increases sharply, that is, through self-fracture, the load is cut off, and the protection Other parts are not damaged.
How to adjust the discharge granularity: the adjustment seat is suspended on the ear seats on both sides of the frame with T-shaped bolts. There is a set of adjustment gaskets between the adjustable seat and the rear wall of the structure. The thickness of the sheet can be adjusted to adjust the width of the discharge port to obtain the required product size.
The function of the tension spring is: the tension spring device is used to ensure the right combination of the entire mechanism of the jaw crusher, and the partial balance is caused by the inertial force generated when the movable jaw and the toggle plate work. If it is too large, as long as it can eliminate the impact sound between the toggle plate and the movable jaw, and the adjustable seat.
