Jaw crusher is mainly used for crushing machine and the broken machine. PE series of simple deep cavity jaw crusher structure, easy to manufacture, reliable, easy to use and maintenance. Widely used in mining, smelting, building material, highway, railway, water conservancy and chemical industry in a variety of ores and bulk materials of medium-grained broken. Maximum compressive strength of the material to be broken for 320Mpa. To make the stable operation of equipment, maximizing benefits for the user to create, install from the jaw crusher to the operation, maintenance and repair should be required to operate. Deep cavity jaw crusher in the installation process, often due to operator error or debug substandard production process later buried hidden dangers. How installation PE jaw crusher is correct? First, the equipment to be installed in a shelter from the rain, not on the open air. The machine should be firmly fixed on the concrete floor, leaving a row of ground ore tank, its inclination not less than 50 degrees. The rear motor to be installed in the crusher, the rotational direction must be made according to the requirements can not be reversed. The nesting population adjustment before, you should loosen tension spring, to be adjusted, and then adjust the spring tension level. Tighten screws before commissioning and connecting parts, check lubrication. In strict accordance with the requirements, by a trained technician to install, the production process in order to reduce jaw crusher failure. PE jaw crusher after proper installation, jaw crusher will be put into production. During operation, how maintenance, when failure, how to solve the problem, a problem of concern to each user. To ensure the normal operation of the jaw crusher, in addition to proper operation, the jaw crusher repairs must be carried out in a planned manner, including routine maintenance checks, minor repairs, repair and overhaul. Jaw crusher minor repairs including inspection and repair adjustment means adjusting the discharge port clearance to turn or replace worn liner. Check the transmission parts, the lubrication system in a timely manner with the change lubricants. Cycle is generally 1-3 months. The repair including the replacement of the thrust plate, lining, inspection and repair adjustment devices. Cycle is generally 1 - 2 years. Overhaul including the replacement of turning the eccentric shaft and bearing jaw broken, replace or repair a worn parts. Cycle is generally about 5 years.
