Equipment introduction: Jaw crusher is a commonly used equipment in infrastructure construction such as engineering, roads and bridges. It is mainly used for crushing some sand and gravel. The jaw crusher is suitable for processing side lengths not exceeding 500mm and compressive strength not exceeding Various coarse, medium and fine materials (granite, limestone, concrete, etc.) of 350 MPa.
Jaw crushers can be used to meet various output of sand and gravel manufacturers. This crusher is beautiful in appearance, strong and durable, and has a large adjustable range, which increases the flexibility of the equipment. Jaw crusher can crush various ores and bulk materials. It is mainly used for crushing stone and sand production line to support the main crushing equipment. The jaw crusher has a large crushing ratio, high output, uniform product size, simple structure, and work. It is reliable, easy to maintain, and economical in operating costs. It is one of the commonly used mine crushing equipment in industrial and mining production.
Application field: Widely used in the medium-size crushing of various ores and bulk materials in mining, smelting, building materials, highways and other industries.
Equipment advantages:1. The crushing cavity is deep and there is no dead zone, which improves the feeding capacity and output.
2. Large crushing ratio and uniform product size.
3. The gasket-type discharge opening 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 replacement of parts is convenient, and the maintenance workload is small.
5. Simple structure, reliable work and low operating cost.
6. The adjustment range of the discharge opening is large, which can meet the requirements of different users.
7. Low noise and less dust.
Working principle: The working part of the jaw crusher is mainly divided into two jaw plates, one is a fixed jaw (fixed jaw), which is vertically (or slightly inclined at the upper end) fixed on the front wall of the body, and the other is a movable jaw ( The movable jaw), the position is inclined, and a large and narrow crushing cavity (working cavity) is formed on the fixed jaw plate. The movable jaw plate makes periodic reciprocating motion against the fixed jaw plate, sometimes separating and sometimes approaching. When separating, the material enters the crushing cavity, and the finished product is discharged from the lower part of the jaw crusher; when it is close, the materials inspected on the two jaw plates are crushed after being squeezed, bent and split.
The crushing method of this series of jaw crusher is curved extrusion type. 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 becomes larger, thereby driving the moving jaw. The jaw plate approaches the fixed position, and at the same time, the material is crushed by multiple crushing, rubbing, grinding, etc.; when the movable jaw moves downward, the angle between the toggle plate and the movable jaw becomes smaller, and the movable jaw plate leaves the fixed position under the action of the pull rod and the spring. The jaw plate, at this time, the crushed materials are discharged from the lower mouth of the crushing cavity.
