Introduction of Jaw Crusher
Jaw crusher is mainly used in the industries of metallurgy, mining, chemical, cement, construction, refractory materials and ceramics, suitable to crush hard and soft ores with compressive strength less than 320 MPa. This machine can break material s into medium size and fine size.
Advantages & Characteristic
1. High capacity and low power consumption;
2. Uniform particle size with high crushing and crushing ratio;
3. Simple structure; Easy operation
4. Low investment.
5. Perfect services.
Working Principle of Jaw Crusher
Jaw Crusher mainly consists of frame, eccentric shaft, jaw plate, connecting bar, adjustment part and spring.
The movable jaw goes upward and downward through eccentric shaft when belt and belt wheel are driven by the motor. The angle between movable jaw and bracket turns big when the movable jaw goes upward, which pushes the movable jaw plate to come closely to fixed jaw plate. At the same time, materials are crushed with the movement of the movable jaw.
When the movable jaw goes downward, the angle between movable jaw and bracket turns small. Under the force of spring and connecting bars, the movable jaw plate leaves fixed jaw plate, and the crushed materials with qualified size are discharged from the crushing cavity. With the continuous rotation of the motor, the movable jaw crushers and discharges materials, which, in turn, realizes the goal of mass production.
Introduction of Hammer Crusher
Hammer crusher is widely used in metallurgy, mining, chemical, cement, coal gangue, construction, sand, refractory material, ceramic and other industrial and mining enterprises, engaged in breaking and crushing the material in the operation. It is mainly suitable for crushing various soft and hard ore. whose compression strength is not higher than 150MPa (MPa),such as coal, salt, chalk, gypsum, blocks, limestone, etc.
Working Principle of Hammer Crusher
The main working part of hammer crusher is rotors with hammer. The rotors consist of main shaft, disk, pin shaft and hammers. The motor drives the rotors to rotate quickly in the crushing cavity. Raw materials enter the crusher through the feed opening and are stricken, impacted, cut and ground by the high-speed hammer to small size.
Introduction of Impact Crusher
Impact Crusher is widely applied in mining, transportation, energy, construction and chemical industry. Impact crushers are ideal choice for crushing and screening. This impact crusher machine features reasonable structure, high productivity, easy operation and maintenance and safe performance. The most outstanding advantage of the impact crusher is that its finished powder is in good, cubic shape and without tensility and cranny
Working Principle of Impact Crusher
High reduction ratio and crushing efficiency;
2> No-board connection; the blow bar with high chrome (high chromed blow bar).
3> Impact plate with a special shape.
4> Crushed product with cubical shape.
5> Easy maintenance and reliable operation
ntroduction of Cone Crusher
hydraulic crusher is suitable to crush various kinds of ores and rocks of medium or above medium hardness. Compared with Jaw Crusher, Spring Cone Crusher is of stable structure, high efficiency, easy adjustment, and economical using etc. The spring safety system of crusher acts as an overloading protection system that allows metals to pass through the crushing chamber so as not to damage the Cone Crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separated to make sure reliable performance. This type of crushing chamber depends upon the size of feeding and fineness of the crushed product. The standard type (PYB) is applied to medium crushing, the medium type is applied to medium or fine crushing and the short head type is applied to fine crushing.
Working Principle of Cone Crusher
hydraulic crusher crushes materials by the working surface between the movable cone and fixed cone. So it is more advanced and efficiency than Jaw Crusher. The movable cone is supported by spherical bearing and fixed on an hanging erect shaft which is set in the eccentric sleeve, and the sleeve is set on the stopping and pushing bearing. The movable cone and erect shaft are driven by the eccentric shaft sleeve together. The eccentric shaft sleeve is driven by horizontal shaft and fimbriated gear, and the wheel of the conveyor belt is driven by motor through v-belts. The lower part of vertical shaft is installed in the eccentric sleeve. When the eccentric sleeve rotates, there is a conical surface lined out by the shaft. When the movable cone comes near the fixed cone, rocks are grinded into pieces, when the cone leaves, grinded materials is discharged from the discharge hole. The fixed cone can be ascended or descended by adjusting setting to adjust the width of discharge hole, consequently the output size is determined.
