SKJ Series European Jaw Crusher Machine For Primary And Secondary Crushing In Quarry And Mining Plant

Main Features of European jaw crusher 1. It adopts world-level manufacturing technology and high-end manufacturing materials. 2. More advanced movable jaw assembly makes it more durable. The movable jaw assembly uses high-quality steel casting and drives through two large-sized cast steel flywheels. In addition, the heavy eccentric shaft also adopts forging stock which makes JC series jaw crusher have extraordinary reliability. 3. The bearing pedestal adopts unitary cast steel structure. The unitary cast steel bearing pedestal can ensure comprehensive fitting with the crusher rack, and at the same time, greatly increase the radial strength of the bearing pedestal, whereas split type bearing pedestal does not have these advantages. At present, the European SKJ jaw crusher has become one of the most popular jaw crusher in expressway, railway, airport runway, mine, building materials, metallurgy, chemical industry and other fields. Working principle The electromotor drives the belt and pulley to make the movable jaw move back and forth, up and down through the eccentric shaft. The raw material is squashed or splitt when movable jaw plate moves towards fixed jaw together with movable jaw. When movable jaw and movable jaw plate turn back by eccentric shaft and spring, the raw material, which is squashed or split before discharges from the bottom outlet under jaw plate. The bulk-production comes true while electromotor rotates continuously and the movable jaw crushes and discharges the raw material periodically. Technical parameters of jaw crusher Jaw crusher features: 1. The jaw crusher cavity is deep and there is no dead zone, which improves the feeding capacity and output; 2. The crushing ratio is large and the product size is uniform; 3. 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, low operating cost; 6. Equipment energy saving: single machine energy saving 15%～30%; 7. The adjustment range of the discharge opening is large, which can meet the requirements of different users; 8. Low noise and less dust. Maintenance of machine： (1) The lubricating grease used for jaw crusher shall be determined according to the place of use and temperature conditions. Generally, calcium base, sodium base and calcium sodium base lubricating grease shall be used. (2) Generally, add 50-70% lubricating oil into the bearing and replace it every 3-6 months. Clean the bearing raceway with clean gasoline or kerosene during replacement. (3) Before starting the jaw crusher, a small amount of lubricating oil shall be injected between the elbow plate and the elbow pad.
