4-footer cone crusher
Cone Crusher is one of the main types of primary crushers in a mine or ore processing plant. Gulin cone crushers can be used for primary or secondary crushing. 4-footer cone crusher is suitable for hard and mid-hard rocks and ores, such as iron ores, copper ores, limestone, quartz, granite, gritstone, etc., it is widely applied in metallurgical, construction, road building, chemical and phosphatic industry.
Features of 4-footer Cone Crusher:
1. Less spare part consuming and low operation cost;
2. between-layer pressuring crushing and better finished product shape;
3. A high crushing ratio and production efficiency;
4. Hydraulic protection and hydraulic cavity clearing, high automatization and less stop production and repairing time;
5. Thin oil lubrication makes the life time increased;
6. Manifold crushing cavity, flexible application, strong adaptability;
7. Easy maintenance and operation
8. The crusher can provide customers a higher capacity, better product shape, and easy be operated.
Portable stone cone crushing plant
Portable cone crusher plant is designed by Gulin to meet the requirements of different rocks and purposes. This equipment instead of 4-footer cone crusher is used for crushing harder and finer products. The crushing chamber of the cone crusher can be exchanged according to actual requirements which expand the application field of mobile cone crusher plant.
Working Principle of Gulin cone crusher
Cone crusher consist of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening. During operation, the motor drives the eccentric shaft shells to turn around through a horizontal axle and a pair of bevel gear. The axle of crushing cone swings with the force of eccentric shaft shell so that the surface of the crushing wall is close to the roll mortar wall from time to time. In this way, the ores and rocks will be pressed and crooked and crushed. The crushing action is caused by the closing of the gap between the mantle line (movable) mounted on the central vertical spindle and the concave liners (fixed) mounted on the main frame of the crusher. The gap is opened and closed by an eccentric on the bottom of the spindle that causes the central vertical spindle to gyrate. The vertical spindle is free to rotate around its own axis. The crusher illustrated is a short-shaft suspended spindle type, meaning that the main shaft is suspended at the top and that the eccentric is mounted above the gear. The short-shaft design has superceded the long-shaft design in which the eccentric is mounted below the gear.
