Jaw crusher is usually used as head breaker in production line, and its output will directly affect the output of the whole production line. How to maximize the production capacity of crusher under the premise of ensuring ore size is a problem that many mining enterprises are very concerned about.
 1. Feeder In order to make jaw plate uniform and reduce operation cost, ore should be uniformly distributed along the entrance of feeder and filled with crushing chamber. 2. Ensure adequate mineral production |
3. Matters needing attention in feeder
(1) Prevent iron from entering the crushing chamber. Iron blocks may damage jaw plates and other parts.
(2) The height of ore should not exceed the fixed jaw plate.
(3) The maximum ore size should be smaller than the feed port size of jaw crusher. Large ore is easy to block the crushing chamber and affect the crushing efficiency.
4. Set a reasonable discharge port size
The setting of discharge port is to adjust the distance between the two jaw plates at the lower end of the crushing chamber. The adjustable range of discharge port for different types of equipment is different. Too small discharge port will cause blockage and excessive energy consumption, resulting in serious damage to the crusher. The excessive discharge port will aggravate the load of the second crushing.
 5. Adjustment of discharge opening Adjusting the opening of the discharge port is realized by increasing or reducing the adjusting gasket located behind the swing rod seat plate. When measuring the set distance, attention should be paid to the position of the eccentric axis above, so that the lower end of the fixed jaw plate and the lower end of the movable jaw plate are in the closest position. In this position, the maximum diameter of a circle tangential to the two jaw plates is measured, and the circle represents the size of the ore. The measuring device uses a ring gauge supplied by a randomizer. After adjusting, the tension spring can not compress too much, so we must avoid the close row of springs. The supporting rod and tension spring are both subjected to fatigue stress and should be replaced within 2-3 years. |
6. Overview of Jaw Plate
The two jaw plates are tooth-shaped and have a flat cross-section design. They can be inverted and interchanged. Therefore, a jaw plate can be installed on both movable jaw and fixed jaw.
7. Wear State of Jaw Plate and Treatment Measures
The wear condition of jaw plate and its adjustment are very effective to improve the working capacity of crusher. It is best to check wear regularly to determine when to invert, exchange and replace the jaw plate.
8. The Importance of Lubrication
High quality lubrication is the key to ensure the performance and life of bearing, and bearing is the core component of crusher operation, which is closely related to crushing efficiency.
