Crushers according to the categories can be divided into medical crusher and mining crusher. Crusher is refers to the discharging granularity is more than 3 mm in content of total discharge capacity is more than 50% of the crushing machine.
Extracorporeal shock wave lithotripsy in the treatment process of advantage is that it is basic to invade human, patients are easy to accept, and its treatment of high success rate, less injury to tissue, at present has been widely used in clinic.
Analysis on wear causes of crusher different parts:
Crusher parts working conditions of the friction surface of the adjacent parts wear and tear is not the same, this is due to:
A relative movement, their load conditions, and different conditions.
Second, the wearability of crusher parts material is different.The nature of the work surface wear along the length and width is decided by the working conditions of the shape of the parts and components.For one is another activity parts is fixed parts of components, four wear distribution of any of the following:
1) load ACTS on the fixed direction.In this case, the screw holding parts of wear surface is uniform along the way, and fixed parts of wear is partial;
2) the direction of the load to part rotation - continuous change.In this case.Activity of wear parts is local, and fixed parts of wear is uniform;
3) loading on fixed direction, and the two parts with different rotation angular velocity.In this case, the two parts wear and tear will be uniform;
4) load direction of continuous change, load force vector and rent a part of the activities in the following with the Angle of short rotation.The wear and tear of parts will be uniform.
Three, crusher amount of wear and tear parts are also different
Crusher wear parts size is determined by a series of factors, generally speaking, mainly by parts of the work environment, work under cutting the size of the load and temperature, the relative movement between parts of speed, the friction and wear of type, the number of lubricating oil quality and lubrication method, the size of the fit clearance between parts and equipment factors such as the merits of the daily operation and daily maintenance.
Practice has proved that all the broken equipment can be strict operation, carry out daily maintenance and maintenance seriously, will reduce the amount of wear parts, extend the life cycle of equipment, improve equipment utilization, on the contrary, in violation of the equipment operation procedures, strengthen the daily maintenance and maintenance will increase the amount of wear parts, even accidents and prematurely for maintenance, this reduces the efficiency of equipment.
Parts of normal wear and tear and wear and tear, accident is harmful for the use of the equipment, the accident is not allowed to wear.In order to improve equipment utilization, must reduce the wear and damage to the parts.In actual production, improve the utilization rate of equipment is an important way to improve wear resistance of the parts, fighting to wear.So serious study parts wear phenomenon and law, discuss the various factors influencing the wear and tear, for improve the measures and methods of abrasion resistance parts is very necessary.
