Types of mining equipment such as jaw crusher, at work, because of the bad environment, so the fault cannot be avoided in production, the influence of some fault for production is large, there are some fault for production is small, the influence of rock is one of the fault, the influence of this phenomenon for production is also cannot be ignored, so we need to promptly solve the problem, to solve this problem, first have to find the reasons, there are two reasons for jaw crusher shaking

 

1. Loosen or break the screw

For the fixed jaw crusher equipment, the need to install before production, installation of time needs to be fixed on the ground, when I was a fixed screw need to use this part, if in production, appeared on one side of the screw loosening or fracture, then the machine will appear slightly shaking phenomenon, if not timely processed at this time, so the late shaking will be more serious, long-term working process will cause the screw fracture phenomenon, which makes the machine is in intense shaking,The solution to this phenomenon is to timely tighten or replace the loose or broken screws, so that the jaw crusher firmly fixed on the foundation, and then the stable crushing work;

 

2. The flywheel deviates from its original position

Fly Geneva wheel is one of the important parts of jaw crusher, which at the time of installation, the position is fixed inside the equipment, but the installation if staff in the installation error, will cause the part deviation from the original position, make the machine centre of gravity is imbalance, and then, the phenomenon of the rock, the phenomenon of the solution is to fly Geneva wheel to adjust the installation location;

Jaw crusher shaking of the two reasons, one is related to the screw, one is related to the position of the slot wheel, for these two phenomena of the solution, if you have a better way, also can communicate with us

For jaw crusher, can complete the processing requirements, mainly depends on its performance are in good condition, and its performance are in good condition and their internal many parts are in good condition, in general, the parts is worn, the potential problems with the production going on, wear phenomenon gradually increase, the performance of the equipment also gradually decline, if worn parts will fail, then the device will stop the production, for internal of jaw crusher parts, some parts wear relatively quickly, these parts belong to wear parts, has an important influence for the work of equipment, the shaft is one of them,What are the problems with the shaft of the jaw crusher?

1. Shaft neck wear

The rotation shaft in use, wear conditions are different, need to take the repair program is different, when the jaw crusher rotation shaft wear is not big, can be plated on the shaft neck a layer of chrome, grinding to the required size;If wear is more, can be on the shaft neck surfacing welding, and then to the lathe cutting polishing;For serious wear condition, turn 2-3mm on the shaft neck, then turn a sleeve, cover on the shaft neck while it is hot, and then turn to the required size;

2. Shaft bending

Jaw crusher shaft bending phenomenon, will also cause the production is difficult to carry out, the repair method and the degree of bending has a great relationship, when the shaft bending is not big, can be repaired by grinding the shaft neck, slip ring method;When the bending exceeds 0.2mm, the rotating shaft can be placed under the press, and the bending part can be corrected under pressure. The surface of the corrected shaft can be polished by lathe cutting.When the bending is too large, a new shaft is needed.

Shaft neck wear and shaft bending phenomenon, for the repair of these two phenomena, jaw crusher shaft no matter which kind of fault, wear or bending degree of different, the need for repair methods are different, only to solve the wear or bending phenomenon, to ensure the smooth working process of jaw crusher.

The roller crusher, as its name implies, its crushing principle is to use the roller of material extrusion to complete the crushing operation, therefore, the roller to roller crusher is an important part.So, the problem came, in the process of operation, on the roller crusher roller cracking how to do?

Under normal conditions of roller crusher roller wear, the appearance of the roller is not cylindrical, forming two big, small center concave outline, then the larger mud block or mud ball can be worn through the concave, play no role in breaking, so it is necessary to repair the roller.There are two methods commonly used in roller repair: local cutting (grinding) machining repair and local surfacing repair.

1. Local surfacing welding

Local surfacing welding is to weld and fill the worn groove of roller crusher.This kind of method is brief and useful, do not affect the production, and surfacing the hardness and wear resistance are better, the defect is only suitable for good weldability roller (such as cast steel roller).
 

2. Local cutting (grinding) method

Local cutting (grinding) method of operation is: on the roller crusher frame, a special tool rack, its moving track should be parallel to the roller axis.Repair start to roll crusher, with manual feed organization (conditional can also choose active feed organization) on the roller cutting.

(1) the running track of the tool rest is parallel to the axis of the roller, preventing the taper after cutting and affecting the crushing effect.

(2) control the roller speed of the crusher.Roller appearance of the linear speed should not exceed the cutting tool allowed cutting speed, otherwise should be adopted to reduce the speed to prevent damage to the tool.

(3) about the high hardness roller, cutting can not be processed, at this time can choose to grinding a head according to the cutting method for grinding processing.

3. Disassembly and repair

The repair method after disassembly is to disassemble the roller with the shaft together and apply it to the machine after repair by turning.This method has large workload, long downtime, but easy and thorough repair.

Roller crusher is a kind of crushing equipment, its feed particle size is relatively small, fine discharge particle size, mainly used in stone production line of secondary crushing, we only ensure the normal operation of roller crusher, to ensure the profit of the enterprise.

What are the problems with the jaw crusher frame?

Product introduction:https://www.cementepc.net/crusher/Jaw-crusher.html

Jiangsu LVSSN company core cement epc

Jaw crusher within different parts, each plays a different role, frame is one of the parts of the machine, also is the basis of its installation, at the same time the parts at the time of use, will bear a larger impact load, the impact load for the service life of the equipment and the working performance has an important influence, so it requires its strength and stiffness can meet the requirements of production, What are the problems with the jaw crusher frame?

1. Analysis of working principle

About the working principle of jaw crusher, presumably everyone not unfamiliar, mainly of the reciprocating motion by using the transmission mechanism to drive, to achieve for stone crushing homework, in the process of the broken stone from large to small, so will produce certain impact, this action will cause the vibration of the frame to produce, therefore, the rack used in jaw crusher, one problem is the choice and design of vibration isolation measures.

2. Cracks appear in jaw crusher

For jaw crusher, the structure of the frame is not a single, some rack belong to the structure of the casting molding, crushing processing jobs in a long time, the filter screen of the particle size is reduced, equipment also row ore mouth gap decreases, this phenomenon will increase rack in production under the impact strength, makes the equipment load increase, this will lead to frame steel plate in the erect crack appears on the surface, the conventional welding cannot make cracks inside achieving full healing, so the welding frame in the running for a few days after will continue to crack, in this way,Jaw crusher frame is basically normal operation after a few days will be for welding time, but due to the structure of the machine problems, every time the welding time is longer, if not timely for welding repair, will lead to frame fracture completely, also cause crusher thoroughly destroyed, it will reduce the service life of equipment, increase the economic burden of production operation;

Jaw crusher frame at the time of use, the problems, through the introduction of the above you can see, mainly is two aspects, one is the selection and design of vibration isolation measures, it is a long time and high frequency welding, will increase the economic burden of the equipment and reduce its service life, so the frame when choosing to pay attention to the stiffness and strength, to pay attention to when using operation is correct, and its load is reasonable.
