The Methods of Decreasing the Abrasion of the Jaw Crusher

In the operation process of the Jaw Crusher, there may be some abrasion. In order to decrease the abrasion of its components as far as possible, you should select the machine scientifically and operate it and select the material reasonably. Certainly, the maintenance of the jaw crusher should also be noticed. Here, SBM will talk about the methods of decreasing the abrasion of the jaw crusher.
In the operation process of the jaw crusher, there will be some problems. For example, the abrasion of the movable jaw plate or the fixed jaw plate will cause the abnormal operation of the jaw crusher and the lack of its crushing capacity. If the jaw plates do not touch the surface of the machine stably, the rotating speed of the eccentric shaft is excessively high, or the crushed material cannot be discharged immediately, the crushing cavity of the machine will get stuck and the jaw plates will be worn. If the angle between the movable jaw plate and the fixed Stone Crushing Plant is too big, which has exceeded the normal range, the machine cannot be of high strength or wear resistance.
You’re reminded by SBM that the new jaw plates must be fastened well and they should touch the surface of the machine stably. There can be a layer of material with nice plasticity between the jaw plate and the machine. There should be a spot test of the material. Once there is big change of the property of the material, the specification of the machine should be changed in time to make it accord with the material. The jaw plate must be made from the material with high hardness and wear resistance. Besides, the worn jaw plate should be replaced immediately.
Only when the jaw crusher is being in the normal operation can the material be fed into it. The material should be fed into the crushing cavity evenly. In the normal case, the temperature of the bearing should not exceed 35℃.

Analysis of the cone crusher in the stress

The cone crusher is an important ore dressing equipment with relatively large body shape. During its operation, the wear of the parts will seriously affect the vibration stability of the Cone crusher in germany, and at the same time, the machine will be in a state of forced vibration for a long time, which will seriously affect the crusher. Safe to run. The study found that the disturbance is an important factor affecting the forced vibration of the crusher. Let us analyze it here.
According to the angular velocity vector diagram of the crusher cone of the crusher, due to the structural characteristics of the crusher cone support device, the crushing cone not only rotates with the eccentric hole of the eccentric bushing around the center line of the machine, but also rotates around its own axis, which is the crushing cone. This kind of movement is called regular movement. Since the center of mass of the crushing cone is not on the center line of its rotation, it is necessary to generate inertial force and moment of inertia during operation. This force acts on the frame as a periodic dynamic load that causes the vibration of the frame and the deflection of the eccentric bushing. When the crusher makes regular movements, it periodically reacts to the frame sleeve and the spherical bearing during no-load, which causes the harmful vibration of the frame machine and the eccentric bushing to be deflected and cannot work normally.
The counterweight of the large bevel gear of the cone crusher is to eliminate the inertial force and the moment of inertia of the direction change caused by the Cone Crusher. Due to the limitation of the size of the crusher, the inertial force of the crushing cone cannot be completely eliminated. Therefore, when the crushing cone rotates, a large unbalanced inertial force is generated. This unbalanced inertial force is caused by the crusher frame and the basic vibration. Disturbance. That is, the disturbance of the crusher is the unbalanced inertial force generated when the crusher’s crushing cone rotates around the central axis. Vibration analysis under disturbance. The vibration of the machine can be divided into two types: free vibration and forced vibration. The body and foundation of the crusher are constantly excited by the outside world, and there is always disturbance during the whole vibration process, so it is a typical forced vibration.

The Analysis on the Quotation of the Sand Making Machine

If one set of sand making machine costs 0.2 million, do you think it is expensive or not? Now, we will make an analysis of the price of the Sand Making Machine and the influential factors of it.
The sand making machine, made by ZENITH Heavy Machinery, consists of the feeding hopper, distributor, eddy-current crushing cavity, impeller, spindle mechanism, foundation, transmission device, electric motor, etc. Most of these components are made from excellent cast steel and some are made from high manganese cast steel. We are extremely strict with the material of the components of our product. One set of sand making machine, the production capacity of which is 55-100 ton per hour, weighs 12.6 ton. As you can guess, it will take much cast steel to produce such a sand making machine, which will cost a lot.
There are many differences between different manufacturers in manufacturing technique, production time, money, and effort. Then, at least, the machine, made by a manufacturer with more than 30 years’ experience and mature manufacturing technique and group, must be cost-effective. ZENITH can be a reliable one!
As for the Stone Crushing Equipment, large-scale mining machinery, you should focus on the cost of its material, components, and the logistics cost of itself. In fact, the logistics cost, which does not account for a big part of the whole cost of the equipment, is still an important factor affecting the price of the sand making machine. You’d better choose a manufacturer, which sits in a first-tier city, for the cost of its machines are more cost-effective.

What waste can the mobile crusher handle?

Before crushing construction waste, we need to know what wastes we need to break, so that when we choose a Mobile crusher in malaysia, we need to equip some equipment to remove useless waste to achieve maximum resource utilization.
Construction waste is generally divided into surplus concrete and construction debris. Residual concrete refers to the concrete that is used in the project and is not used out. Also included for some reason. If the concrete is suspended due to weather changes and is not used in time, we usually use a box-type mobile crusher to process large pieces of concrete. Building scraps include mineral materials such as old concrete mortars produced by plastering. And types of wood paper metal and other scraps. In addition, it also includes waste generated by the decoration of new houses. There are mainly scrap steel wire and various scrap steel parts, metal tube residual scrap, waste bamboo wood, wood chips, packaging materials for various decorative materials. These materials are usually handled by a squatting Mobile Jaw Crushing Plant, which is equipped with a separator, a multi-layer vibrating screen, and the like.
Broken bricks are mainly used for building load-bearing and retaining walls. The main reason for the generation of broken bricks is
1, the group is not properly cut. The design does not conform to the building modulus or the selection of bricks, such as improper specifications, brick size and shape, and the bricks are not allowed to be caused by other reasons.
2. The transportation is damaged. Bricks or bricks designed to use excessive strength grades are inherently of poor quality and contractors are not properly managed. Order too much, etc.
3. Mortar is mainly used for masonry and plastering. The main reason for the generation of mortar waste is that it is inevitably scattered during the construction operation, and excessive transportation and scattering are also the causes of mortar waste.
4. Concrete is the most important, and building materials are used for foundation. Structural parts such as floor slabs and shear walls. The main causes of concrete waste generated during construction are the scattered, beneficial effects during the pouring, the scattering during transportation, the excessive ordering of commercial concrete, and the suspension of construction for some reason and not used in time.
5. Packaging Waste The packaging of various building materials scattered on the construction site is also part of the waste.
