Impact crusher problems and solutions source dsmac by liu lerry posted may 03,2016 views there is no perfect crushing equipment, even impact crusher is suchopular device, there are still many problems after usingong time, lets solve them one by one. 1, fever and even burned bearings impact crusher rotor rotating at high speed when.
The jaw crusher is composed ofovable jaw andtatic jaw to formrushing cavity, which simulates the movement of the animals jaws to complete the material crushing operation. used in the crushing of various ores and bulk materials in mining smelting, building materials, highways, railways, water conservancy and chemical industries. so what are the.
Solution the fundamental problem is that the impact blow bars substandard quality, it is recommended to recreate the mold bolt, the bolt head oval better contact with the blow bars screw contact surface, the thickness of the thread bolt controlled dimensional tolerances within to prevent stress concentration and fracture addition, it must be.
Bearing as an important part, used inariety of large and small machinery, and some machinery such as crusher work in the environment of dust, when part of the fine dust into the highspeed operation of the bearing seat, resulting in the bearing seat lubricating oil or grease deterioration, poor lubrication, then make the bearing wear.
1 clear the blockage at the discharge opening to ensure unimpeded discharge.ighten or replace the vbelt.einstall or replace the bushing.djust the voltage of the work site to meet the requirements of the working voltage of the engine.eplace the bearing. the main machine sheaves and movable jaw run well, but the crushing stops.
The specific causes of bearing heating include 1. when assembling the crusher, the outer ring, the bearing seat, or the inner ring of the bearing and the shaft are not correctly matched. during the assembling process of the crusher, the inner hole was not repaired, and its size was measured, and new bearings were replaced for assembly.
Bearings skf is the world leader in the design, development and manufacture of high performance rolling bearings, plain bearings, bearing units and housings. machinery maintenance condition monitoring technologies and maintenance services from skf can help minimize unplanned downtime, improve operational efficiency and reduce maintenance costs.
2. the transmission device and the analyzer emit heat. reasonshe oil viscosity is high and the oil is thick, which make the thread oil pumping hard to spray and the upper bearing is lack of oil. solutionsheck and make sure the model and viscosity of the engine oil is the same as they are demanded.
Increase bearing vibration noise. severe brinell marks can cause premature fatigue failure. any static overload or severe impact can cause brinelling. examples include using hammers to remove or install bearings, dropping or striking assembled equipment, andearing ontohaft by applying force to the outer ring. install bearings by applying.
To solve this, the operator can replace the blow bar withew one. the third reason is that the rotor loses balance and needed to be adjusted. the last one is that the base is unstable. the operator should check the foundation bolts and tighten them. 2.problem the bearings in impact crusher heat. reasons and solutions the bearings are lack.
Spherical bearing. the spherical bearing should be installed in the borehole of crusher closely. solution heat the oil turn on the oil switch turn off the crusher and change the oil pump. solution check the straight sleeve and cone sleeve after turning off the crusher, and find the problem to solve it. the scavenge oil in the fuel.
A crusher isevice that crushes materials in the form of impact. it is divided into singlerotor crushers and doublerotor crushers. the specific causes of bearing heating include 1. when assembling the crusher, the outer ring, the bearing seat, or the inner ring of the bearing and the shaft are not correctly matched.
The working environment of bearing wear crusher is very dusty. when some fine dust enters the highspeed running bearing seat, the grease in the bearing seat deteriorates and lubricates poorly, and then the bearing wears. in order to thoroughly solve the heating problem of bearings, the level of bearing base was also checked, and it was.
6 it is nonbearing temperature rising, but the sealing sleeve of the movable jaw rubs with the end cap, which causes friction heating, or the double embedded cover of the frame bearing seat and the spindle rotate together, causing friction and heat. solutionsccording to the instructions, refuel on time.lean up oil holes and oil sump.
