Deep cavity heavy jaw crusher Supply coal jaw crusher Large output fully automatic jaw crusher

Deep cavity jaw crusher is used for medium-sized crushing of various ores and bulk materials.

In mining, building materials and infrastructure departments, jaw crushers are mainly used as coarse crushers and medium crushers. According to the width of the feed opening, it is divided into three types: large, medium and small: the feed opening width is greater than 600MM for large jaw crushers, the feed opening width is 300-600MM for medium jaw crushers, and the feed opening width is less than 300MM for small crushers. It is mainly used for medium-sized crushing of various ores and bulk materials, and can crush materials with a compressive strength of no more than 320Mpa, divided into coarse crushing and fine crushing.

Performance characteristics

1. The crushing chamber is deep and has no dead zone, which improves the feeding capacity and output.
2. It has a large crushing ratio and uniform product particle size.
3. The gasket-type discharge port adjustment device is reliable and convenient, with a large adjustment range, which increases the flexibility of the equipment.
4. The lubrication system is safe and reliable, the parts are easy to replace, and the maintenance workload is small.
5. The structure is simple, the equipment is energy-saving, the operation is reliable, and the operating cost is low.
6. The discharge port adjustment range is large, which can meet the requirements of different users.
7. Low noise and less dust.

Working Principle

The structure of the jaw crusher mainly consists of a frame, an eccentric shaft, a large pulley, a flywheel, a movable jaw, a side guard plate, a toggle plate, a toggle plate back seat, a gap adjustment screw, a reset spring, a fixed jaw plate and a movable jaw plate, among which the toggle plate also serves as a safety. This series of jaw crushers adopts a cam-type crushing method. The motor drives the belt and pulley, and the movable jaw moves up and down through the eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the movable jaw increases, thereby pushing the movable jaw plate to approach the fixed jaw plate. At the same time, the material is squeezed, rubbed, and crushed in multiple ways; when the movable jaw moves downward, the angle between the toggle plate and the movable jaw decreases, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and the spring. At this time, the crushed material is discharged from the lower opening of the crushing chamber. As the motor rotates continuously, the movable jaw of the crusher performs periodic crushing and discharging, realizing mass production.
