jaw crusher liners

jaw crusher liners,The jaw plate of the jaw crusher is referred to as the jaw plate, and the jaw plate is divided into a fixed jaw plate and a movable jaw plate, which are the wear-resistant parts of the jaw crusher. In the operating state of the jaw crusher, the movable jaw is attached to the movable jaw to perform compound pendulum motion, forming an angle with the fixed jaw to extrude the stone. Therefore, the jaw plate is a relatively easily damaged accessory (referred to as: wearing part) in the jaw crusher.

The jaw plate is the main wear-resistant part of the jaw crusher: the movable jaw plate and the static jaw plate. According to the different models of the jaw crusher, there are various types and sizes. The jaw plate is made of new high-manganese steel, ultra-high manganese steel, Super-strong high-manganese steel and other materials are suitable for jaw crushers of various specifications. The jaw crusher is composed of a working cavity composed of a movable jaw and a fixed jaw. The movable jaw and the fixed jaw bear the huge crushing force and the friction of the material, and are easy to wear out. A wear-resistant lining board is installed on the surface, which is also called a crushing board. The surface of the crushing plate is usually made into a tooth shape. The angle of the tooth peak of the crushing plate is 90°~120°, and its size is determined by the nature and size of the material to be crushed. When crushing large pieces of material, the angle should be larger; When bulk materials, the angle can be smaller. The size of the tooth pitch depends on the particle size of the product, which is usually approximately equal to the width of the discharge port, and the ratio of the tooth height to the tooth pitch can be taken as 1/2 to 1/3. When working, the wear speeds of the upper and lower parts of the crushing plate are different, and the lower part wears faster than the upper part. When the jaw crusher is working, the crushing plate is in direct contact with the material and bears huge crushing force and friction of the material. The service life of the crushing plate is directly related to the working efficiency and production cost of the jaw crusher. Therefore, it is particularly important to extend the service life of the crushing plate of the jaw crusher. Strengthening the service life of the jaw crusher's crushing plate can be considered from the aspects of design, material selection, assembly and improvement during use. The biggest consumption in the production of the crusher is the jaw plate, so the quality must be controlled in the selection of talents. It can also be said that the quality of a crusher is actually based on the service life of the jaw plate. The shell is generally not easily damaged.
