Working principle and classification of jaw crusher

Jaw crusher in the mining, building materials, infrastructure and other departments are mainly used for coarse crusher and crusher. In accordance with the size of the feed width is divided into large, medium and small three, feeding the width of more than 600MM for large machines, feed width of 300-600MM for the medium-sized machine, the feed port width of less than 300MM for small machine. Jaw crusher structure is simple, easy to manufacture, reliable.

Working principle and classification of jaw crusher

Jaw crusher part of the work is two jaw plate, one fixed jaw (fixed jaw), vertical (or the top slightly inclined) fixed on the front wall of the body, the other is the movable jaw (moving jaw), position Tilted, with the fixed jaw to form a large crushing chamber under the small (working chamber). Moves the jaw plate to the fixed jaw plate makes the periodic reciprocating movement, sometimes separates, sometimes approaches. When separated, the material into the crushing chamber, the finished product from the lower part of the discharge; close to the two jaw plates in between the material by extrusion, bending and splitting the role of broken.
Jaw crusher jaw in accordance with the activities of the swing in different ways, can be divided into simple swing jaw crusher (simple jaw crusher). Complex swing jaw crusher (compound pendulum jaw crusher) and integrated swing jaw crusher three.

Jaw crusher use and use of

E-crusher is called E-break, this series of products with a crushing ratio, product size uniformity, simple structure, reliable, easy maintenance, operating costs and other economic characteristics. Crusher crusher (jaw broken machine) is widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industry and other departments, broken compressive strength of not more than 320 MPa of various materials.

Jaw crusher use and use of

Jaw crusher use and use of:
    1, the series of jaw crusher (E broken) is mainly used for metallurgy, mining, chemical, cement, construction, refractory materials and ceramics and other industrial sectors in the crushing and crushing a variety of hard ores and rocks.
    2, the series of jaw crusher (jaw broken) is best suited to crushing compressive strength of not more than 300MPa (MPa) of a variety of hard and soft ore, the maximum size of broken materials shall not be greater than the technical parameters of the table.
Jaw Crusher works:
    The working principle of this series of jaw crusher (jaw crusher) is curved extrusion type. Its working principle is that the motor drives the belt and the pulley, moves the movable jaw up and down through the eccentric shaft. When the moving jaw rises, the movement between the bracket and moving jaw When the moving jaw down, the bracket and moving jaw angle becomes smaller, moving the jaw plate to move the jaw plate to the fixed jaw plate close to the same time, the material is crushed or split, to break the purpose; In the rod, under the action of the spring, leaving the fixed jaw plate, this time has been broken material from the crusher cavity discharge. With the motor continuous rotation and crusher jaw for periodic movement crushing and excretion of materials, to achieve mass production.

Brief introduction of performance characteristics of jaw crusher

Jaw crusher, commonly known as E broken, also known as the tiger's mouth. By the moving jaw and jaw jaw composed of two crushing cavity, the simulation of animal jaw movement and the completion of the material crushing operations crusher. Widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries in a variety of ore and large pieces of medium-sized particle size. The maximum compressive strength of the crushed material is 320Mpa.

Brief introduction of performance characteristics of jaw crusher

Features:
1, an effective solution to the original limestone crusher due to low output caused by the high rate of operation, no maintenance time problems.
2, to complete large pieces of limestone broken, the largest broken particle size of 1000 * 1200mm, an effective solution to the original "one side is the supply of limestone, while large quantities of limestone can not be used to store the problem.
3, the mixing of two materials, good uniformity, a substantial increase in the amount of desulfurization limestone. Doping can reach 60%, effectively reducing the cost of raw materials.
4, power consumption has declined. 1 ton of limestone power consumption down 1-2KWh / t per year to save electricity 100,000 yuan.
5, the waste particle size is small, only 2-15mm effective solution to the original limestone particle size, often blocking the slider even affect the mill production problems
6, the effective improvement of the labor intensity and working environment. As the limestone crusher high level of automation, no manual contact with materials, workers greatly improved working conditions.

Jaw crusher is mainly used as coarse crusher and medium crusher

    Deep cavity jaw crusher in the installation and commissioning process, often due to operational errors or commissioning failed to lay the next production process unsafe. How to install and debug PE jaw crusher is correct? First of all, the equipment to be installed in the place of rain, not on the open air. The machine should be firmly fixed in the concrete ground, ground to leave the discharge slot, the slope of not less than 50 degrees. Motor must be installed in the crusher behind, the direction of rotation must be made as required, not reverse.
    Adjust the discharge port, you should first release the tension spring, to be adjusted, and then adjust the tension of the spring. Tighten the screws and coupling parts before the test, check the lubrication. In strict accordance with the requirements, by a trained technical staff to install, in order to reduce the production process jaw crusher failure. PE jaw crusher in the correct installation and commissioning, jaw crusher will be put into production. In the operation process, how to maintain, failure, how to solve the problem in time, is the concern of each user. In order to ensure the normal operation of jaw crusher, in addition to correct operation, jaw crusher maintenance must be planned to carry out, including routine maintenance inspection, minor repairs, repair and overhaul.
    Jaw crusher minor repairs include the main check and repair adjustment device, adjust the discharge port clearance, worn on the liner or U-turn replacement. Check the transmission part of the lubrication system with a timely manner for lubricants. Cycle is generally about 1-3 months. In the repair, including replacement of thrust plate, liner, check and repair adjustment device. Cycle is generally 1-2 years. Overhaul includes replacement of turning eccentric shafts and broken bearings, replacement or repair of wear parts. Cycle is generally about 5 years.
