Jaw Crusher Introduction

This series of jaw crusher features large crushing ratio, uniform product size, simple structure, reliable work, easy maintenance and economical operation. The jaw crusher is widely used in mining, smelting, building materials, roads, railways, water conservancy and chemical industries, and crushes various materials with compressive strength not exceeding 320 MPa.

1. This series of E-Break is mainly used in the industrial sectors such as metallurgy, mining, chemical, cement, construction, refractory materials and ceramics for medium and fine crushing of various medium hard ores and rocks.

2. This series of E-break is more suitable for all kinds of soft and hard ore with crushing compressive strength not higher than 320MPa (MPa). The maximum block size of the crushed material shall not exceed the technical parameter table.

Jaw crusher structure

The frame is a four-wall rigid frame with an upper and lower opening. It is used to support the eccentric shaft and bear the reaction force of the broken material. It requires sufficient strength and rigidity. It is generally cast in cast steel, and the small machine can also replace the cast steel with high-quality cast iron. The frame of the mainframe needs to be cast in sections, and then bolted together to form a whole, and the casting process is complicated. The frame of the homemade small jaw crusher can also be welded with thick steel plates, but the rigidity is poor.

Both the fixed and the squat are composed of a trampoline and a seesaw, which is the working part and is fixed to the trampoline with bolts and wedge iron. The fixed boring machine is the front wall of the frame. The moving boring machine is suspended on the shaft and has sufficient strength and rigidity to withstand the crushing reaction force. Therefore, it is mostly cast steel or cast iron.

The eccentric shaft is the main shaft of the jaw crusher and is made of high carbon steel due to its large bending torque. The eccentric portion shall be finished, heat treated, and the bearing lining shall be cast with babbitt. The eccentric shaft is equipped with a pulley at one end and a flywheel at the other end.

The adjustment device has wedge type, pad type and hydraulic type, etc., generally adopts wedge type, consisting of two wedges before and after, the front wedge can move back and forth to withstand the rear push plate; the rear wedge is adjustable wedge, can be up and down Moving, the slopes of the two wedges are reversely fitted, and the screw moves the rear wedge up and down to adjust the size of the discharge port. The discharge port adjustment of the small jaw crusher is realized by increasing or decreasing the amount of gasket between the thrust plate support and the frame.

The flywheel of the jaw crusher is used to store the energy during the hollowing stroke, and is used for industrial formation, so that the work of the machine is uniform, and the pulley also plays the role of the flywheel. The flywheel is often made of cast iron or cast steel. The flywheel of the minicomputer is often made in one piece, the flywheel is manufactured, and the static balance should be paid attention to during installation.

Eccentric shaft bearings are usually lubricated with concentrated circulation. The support surfaces of the mandrel and the thrust plate are generally oiled by a manual oil gun using grease. The swing angle of the moving jaw is very small, which makes the lubrication between the mandrel and the bearing bush difficult. Usually, a plurality of axial oil grooves are opened at the bottom of the bearing bush, and a ring is opened in the middle to connect the oil groove, and then the oil pump is used to force the dry butter to be lubricated.

The important application of jaw crusher in industry

Coal gangue is an important energy source and one of the important economic sources in China. Coal gangue is a kind of mining solid waste. Its coal gangue produces not only coal, but also the choice of coal. A mixture of coal and rock discharged from washing in a coal washing plant, semi-coal road and rock tunneling, and chalk outside the coal system stacked with coal gangue. With the expansion of coal output scale, the production of coal gangue has been increasing, the environmental problems have become increasingly prominent, and the task of management has become increasingly arduous. The treatment and utilization of coal gangue has become one of the prominent problems faced by many coal enterprises in the development process. It is also being used more and more.

The jaw crusher is abruptly broken, and it is an early crushing equipment. Because of its simple structure, firmness, reliable work, easy maintenance and overhaul, and relatively low production and construction costs, it is still widely used in metallurgy and chemical industry until now. Industrial sectors such as building materials, electricity, and transportation.
