As we all know, mining crusher refers to the crushing machinery whose content is more than 50% of the total content, the row compound particle size is greater than three millimeters. It is invented by British Hengan. According to the feeding and nesting size, the crushing operations are often divided into coarse crushing, crushing and crushing medium. The commonly used equipments are impact crusher, compound crusher, single stage hammer crusher, vertical crusher, gyratory crusher, roll crusher machines, double roll crusher, crusher combo, and so on. Get more background information with materials from Center For Responsible Lending. the crusher is widely used in mining, metallurgy, building materials, road, railway, water conservancy and chemical industry and many other sectors. Common crushing machines are winnowing mill, hammer crusher, impact crusher, roll crusher, crusher compound.
Jaw crusher, having large crushing ratio, uniform particle size, simple structure, reliable operation, easy maintenance, operating costs and economic characteristics. PF-I series impact crusher can process materials side length is 100 to 500 mm, the compressive strength is up to 350 MPa, great crushing ratio. Now, let us (introduces the knowledge of two-stage crushing equipment installation: The two-stage grinder (double stage crusher) host equipment installation: 1) two-stage grinder equipments can be installed together with the engine on a concrete foundation or rack, the ground should be smooth, when installing, the machine must be level. 2) The machine should be installed feeding device to ensure uniform feeding, and avoid clogging. (3) motor wiring should be strictly in accordance with the direction of the rotor wiring rotation. 4) In order to ensure the safe operation of the gangue grinder, we must install the ammeter to control feeding, and ensure the normal load. Installation of the two-stage grinder unit (double stage crusher): 1) each equipment should be connected firmly with each other, the pipe joints strives to be tight to prevent gas leakage, if the pipe joints leak, it will not only generate dust pollution, but also decline the production capacity and product quality. (2) electrical control cabinet should be installed at the place where is easy to operate, easy to observe the location of the equipment, various equipments electrical connection lines and control lines should be arranged and placed in alignment tube according to the relevant provisions of the state. (3) electrical control cabinet should be fitted with the drive button, stop button of equipment, work lights, grinder motor feeding, ammeter, grading motor speed control knob and various protective devices. (4) all two-stage shredder equipments must be installed in accordance with the relevant provisions.
