The newly installed jaw plate must be fixed tightly, installed well, and the surface of the jaw crusher contacts smoothly. A layer of material with good plasticity can be padded between the jaw plate and the surface of the jaw crusher. Every batch of materials entering the crusher should be sampled and checked. Once there is a great change in the nature of the materials, the parameters of the crusher should be changed in time to match the materials entering the crusher.

We must choose materials with high hardness, wear resistance and strong resistance. Cement enterprises with mine crushing production line technology can exchange the same type of wear jaw plate of mine crushing and cement crushing. The worn jaw plate can be repaired by surfacing.

Another is to pay attention to the working process: after the crusher is in normal operation, it can start feeding; The crushed materials should be evenly added into the crushing chamber, and side feeding or stacking feeding should be avoided to prevent unilateral overloading. Under normal conditions, the temperature rise of the bearing does not exceed 35 ℃, and the maximum temperature does not exceed 70 ℃.

If the temperature exceeds 70 ℃, the jaw crusher should stop immediately and the cause should be found out to eliminate. Before shutdown, the feeding should be stopped first, and the motor can be shut down only after the crushed material is completely discharged from the crushing chamber. When crushing, if the material in the crushing chamber is blocked and stops, the motor should be shut down immediately, and the material must be cleared before starting again. After one end of the gear plate is worn out, it can be used with adjustable head.

1. High efficiency jaw crusher has added hydraulic lifting device in the whole system, making the maintenance of equipment more convenient.

2. Jaw crusher can control product grain level by optimizing multiple variables. For example, change the rotor speed of sand making machine; Using different annular crushing cavity; Adjust waterfall flow; The adjustment of finished particle size is realized by means of rotor with different diameter.

3. Because of low maintenance requirements and easy operation, the impact sand making machine can be easily and quickly matched with existing or planned crushing equipment.

4. The jaw crusher is simple and quick to install. The crusher only needs a few supporting structures and is an ideal mobile device.

5. Be able to control product grain size, so as to maximize or minimize fine material production.

6. Capable of producing products of high grade cubes.

7. Excellent single particle dissociation characteristics of jaw crusher to improve mineral recovery.

8. Selective crushing.

9. Various models can be used for any fine crushing.

The barite mill is short for counter-roll crusher. The barite mill has the advantages of reliable operation, simple maintenance, low operation cost and adjustable size of discharging material. According to the number of rolls, it can be divided into two-roll crusher and four-roll crusher.

The tooth shape, size and arrangement on the roll surface can be changed with the nature of the material. It can crush medium-hard and soft ores. For example, in sulphuric acid plant, the barite millis usually used to crush pyrite once, so that the diameter of pyrite can reach 20-30 mm, and then enter the double-roll crusher for secondary crushing, so that the ore diameter can reach.

Under 5 mm, it meets the requirement of fluidized bed furnace. It can be widely used in the processing of brittle and tough materials in cement, metallurgy, chemical industry, electric power, coal and other industries.

Mobile jaw crusher is suitable for crushing medium hardness materials such as limestone, slag, coke, coal and other materials in cement, chemical industry, power, metallurgy, building materials and other industrial sectors.

The mobile jaw crusher is mainly composed of rollers, roller support bearings, compaction and adjustment devices and driving devices. Next, I briefly introduce several aspects that need attention in the operation of mobile jaw crusher.

First: Preparation

• 1. Check whether the parts are complete and intact.
• 2. Check whether the safety device, lighting and signal are in good condition.
• 3. Check whether the amount of oil injected is enough. Fuel quantity should be appropriate, oil quality should be clean, and lubrication should be good.
• 4. Check whether there are foreign bodies in the mobile jaw crusher.
• 5. Check whether the cushioning device is flexible and reliable, whether the load pins are intact, whether dust-proof and spraying devices work.

Calcite crusher is an efficient crushing equipment, which stands out among many crushing equipment because of its efficient working principle and reasonable structure design. The crusher crushes materials with less energy consumption to achieve more efficient crushing efficiency, and is one of the current crushers with higher efficiency. 

The following SBM Mining Machinery Manufacturer will give you a detailed description of the working principle and structural characteristics of the calcite crusher.In order to be safe, the transmission part should install the safety cover by itself according to the actual situation.

The calcite crusher has the advantages of reliable operation, simple maintenance, low operation cost and adjustable size of discharging material. According to the number of rollers, it can be divided into two-roll crusher and four-roll crusher. It can be widely used in the processing of brittle and tough materials in cement, metallurgy, chemical industry, electric power, coal and other industries. Roller crusher is used for crushing and fine crushing of ores and rocks below medium hardness in mineral processing, chemical, cement, building materials and other industrial sectors.

In addition, the improved wet ball mill equipment also has the following characteristics:

1. The design of large drainage outlet has increased the production capacity.
2. Small ball mill with diameter less than 2.1 meters (excluding 2.1 meters) adopts integral frame, which is convenient for civil construction and equipment installation.
3. Oil mist lubrication device can ensure reliable lubrication of large and small gears. 

The main part of the wet ball mill of SBM Mining Machinery Co., Ltd. is a cylinder with smaller diameter and larger length. It rotates slowly through the transmission device. The material is fed from the feeding end of the cylinder. In the cylinder, due to the drop impact and self-grinding of the steel ball and the ore itself, the material is crushed.

In the cone crusher structure, wear often occurs, especially in the lower 1/3, the wear situation is more prominent. The wear of the dynamic and static frontal plates can cause the crusher to fail to operate normally and lose the crushing ability. There will be wear and tear in the crusher during its working process, which can be reduced and unavoidable. Wear will shorten the mechanical life, so try to reduce it. The crushing machinery also has some wear and tear in the process of processing ore. 

In order to minimize the loss of parts, it is necessary to adhere to the scientific selection of models, and rational use and selection of materials. Once the type selection is inappropriate, serious conditions will result in long-term passive production in factories, and light conditions will also result in frequent multi-consumption. The crushing methods are mixed crushing and pre-screening crushing. 

Mixed crushing refers to the production process in which two kinds of raw materials are fed into a crusher in a certain proportion for crushing. Common mixed crushing are limestone and marl, limestone and shale, limestone and clay, etc. Screening raw materials before crushing, only crushing the screening materials, often can achieve good results.

1. If the main bearing, liner bolt, grate plate, screw in and out of material, mill liner and so on are badly worn, they should be replaced in time and can not work reluctantly. 

2. If there is abnormal noise during the operation of the machine, stop and eliminate it in time, so as to avoid machine failure, and often check whether iron or other large hard objects are mixed into the tank.

3. Check the chains, sprockets and bearings regularly. If problems are found, they should be dealt with in time. Note that the chain tightness should be moderate. If it is too tight, the chain will break easily. If it is too loose, it may be damaged by hanging the drum or guide rail.

4. Check the wear condition of big and small gears regularly. If the wear is serious, it should be replaced in time to avoid affecting the normal work of energy-saving mobile crusher.
