The service life solution of rolling mortar wall of cone crusher

Product introduction:https://www.lvssn.com/crusher/Cone-crusher.html

In the cone crusher, the crushing cavity is formed by the cavity between two lining plates: namely, the cavity between the rolling mortar wall (fixed cone lining plate) and the crushing wall (moving cone lining plate).It can be seen that the broken wall and the rolling mortar wall are the parts directly in contact with the materials, and they are also the main wear-resistant parts in the cone crusher.So, cone crusher rolling mortar wall broken wall service life solution, cone crusher broken wall and rolling mortar wall can be used for how long?What are the factors that affect its service life?How to replace after wear and tear?
 

1. How long can the broken wall and mortar wall last?

 

The rolling mortar wall and the broken wall are the main parts which work together in the broken cone.During the operation of the cone breaking, the broken wall will make track movement, and the distance between the broken wall and the rolling mortar wall will be close to and away from, until the crushed material is extruded, and part of the material will be discharged from the edge discharge port.In the cone crusher, the broken wall and the rolled mortar wall are the main parts in direct contact with the materials, and the service life is about 6 months.
 

2. Factors affecting the service life of broken wall and rolling mortar wall

Generally, these factors affect the crushing effect and service life of the broken wall and rolling mortar wall: the content of stone powder and water content, the hardness and particle size of the stone, the way of feeding, the quality of the broken wall and rolling mortar wall itself.

 

2.1 stone powder content and moisture content

When the cone crusher works, if the stone powder content and water content of the material is relatively high, it will lead to easy adhesion to the broken wall and rolling mortar wall during crushing. A long time will not only reduce the production efficiency, but also cause corrosion to the broken wall and rolling mortar wall, reducing its service life.
 

2.2 hardness and particle size of stone

According to the different hardness of the broken material of the cone crusher, the degree of wear on the broken wall and the rolling mortar wall is also different.The higher the hardness of the material, the more difficult it is to break, the greater the impact load the broken wall and rolling mortar wall bear in the production, and the service life will be shortened accordingly.When the hardness of the ore is the same, the larger the particle size of the ore entering the crushing chamber is, the more serious the wear of the lining plate will be, and the service life will be shortened.
 

2.3 feeding method

The feeding mode of the cone crusher also has a certain influence on the service life of the broken wall and the rolling mortar wall.If the feeding device of the cone crusher is not installed properly, or too much material is put into the crushing chamber, it will lead to uneven feeding, material blockage in the crushing chamber and other faults, so that the crushing wall rolling mortar wall unilateral stress is too large, increase the cutting wear of the ore, so that the lining plate is seriously damaged, the service life will be reduced.
 

2.4 quality of broken wall and rolled mortar wall itself

Above is the external factors affecting the crushing wall and rolling mortar wall, crushing wall and the quality of the rolling mortar wall itself are the main factors, a good quality wear-resistant parts, on the surface of casting is requires a high degree of castings are not allowed to have cracks and impact performance of slag inclusion, sand inclusion, cold insulation, blow hole, shrinkage cavity, shrinkage porosity, casting defects such as lack of meat.At present, the market cone crusher crushing wall rolling mortar wall generally made of high manganese steel.With the continuous development of science and technology, the performance of wear-resistant materials is also improving.Overall, choose a material that can harden quickly under impact loading to form a hard and wear-resistant surface while still retaining the original toughness of the inner metal.In this way, the service life of broken wall and rolling mortar wall can be improved.
 

3. How to replace the broken wall and mortar wall?

When replacing the broken wall and rolled mortar wall of the cone crusher, it is necessary to check the wear of the fixed cone, adjusting ring, locking thread, counterweight and counterweight protection plate.If wear and tear should be replaced with a new, and then install the liner, which can reduce the second replacement disassembly time, save time and effort.After installation, please check whether the center of the lining plate is aligned, otherwise, the lining plate will cause serious wear in collision during operation.

 

3.1 replacement of rolling mortar wall

Rolling mortar wall can be replaced on site.Unscrew the installed on the computer on the shelf adjustment screw (note that spin counterclockwise), remove the chamber on the hopper assembly, hoist with lifting equipment adjustment screw, remove the adjustment screw plate bolt, can remove the rolling mortar wall and exchange, should wash the surface when assembling, adjusting screw thread surface besmear butter, fitted with fixed in accordance with the order.

Note: there are u-shaped screws on the rolling mortar wall, and zinc alloy is injected between them to make them closely combine. When the rolling mortar wall is newly installed or replaced, its tightening condition should be checked after 6-8 hours of work, and the u-shaped screws should be tightened again.
 

3.2 replacement of broken wall

Broken walls can be replaced on site.Hoisted out spindle assembly, in strong support platform, careful not to damage the cone and sphere, and all the oil hole cloth block in order to avoid dust impurities, in turn, remove the distribution plate, lock nut and lock washer, fusible washers, at the site of the old plate 180 ° apart two lug on the welding, it can be broken wall hanging out, also can install the new wall on which the parts are separated by 180 ° is just as two lug on the welding, and then according to the installation, and remove the reverse order finally finished cut two lug.

Note: the cone crushing wall is fixed on the cone body with the cone head, and zinc alloy is cast between the two sides. After the newly installed or replaced cone crushing wall works for 6-8 hours, check its tightening condition, and tighten it immediately if found loose.

The broken wall and rolled mortar wall are important parts of the cone crusher. During the operation of the cone crusher, it should be noted that the materials put into the equipment must meet the crushing requirements. Excessive hardness, excessive moisture or other non-broken materials are strictly forbidden to enter the crushing chamber, otherwise, the broken wall rolling mortar wall will fall off and the equipment will stop.At the same time, cone crusher feeding must be uniform, ore must be in the middle of the distribution plate, material can not directly with the broken wall and rolling mortar wall direct action, to prevent wear uneven.
