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.

1) Before starting the equipment, the operator should carry out a comprehensive inspection of the equipment, including bolt tightening in all parts, reducer oil level and bearing lubrication.

2) Jaw crusher should start without load, and only when it reaches normal speed and has no abnormal condition can it start feeding. The feeding should be stopped before normal shutdown, and only after the material in the crushing chamber is discharged can the shutdown be stopped, except in special cases. No start-up with load is allowed.

3) After long-term shutdown or before the initial start-up, the jaw crusher should be thoroughly checked to see whether the bolts are loose, whether enough lubricating oil is injected into the reducer, whether lubricating grease is added to the bearings, whether the wiring of the electrical circuit and the control switch is correct, whether the wiring is loose or not, and whether the material in the crushing chamber has been cleared. After confirming the correctness, start the jaw crusher and observe whether the direction of the jaw crusher is correct, then the jaw crusher can be officially started.

As the most widely used vertical roller millin vertical roller mill equipment, with its excellent grinding technology, it is widely used in mineral processing, building materials and chemical industry.

The working efficiency of vertical roller mill in operation is affected by many factors, among which the rotational speed plays a vital role in the production process of vertical roller mill. The rotational speed of vertical roller mill is adjusted according to the different crushing degree of equipment. How to regulate it? SBM Mining Machinery Co., Ltd. for your detailed analysis:

The vertical roller mill can be divided into fine grinding and rough grinding according to the needs of users and different materials. When fine grinding is carried out in industrial production, we should adjust the speed of vertical roller mill. The principle is that when the speed of the vertical roller mill is low, the grinding medium will roll down when it is brought to a certain height by the drum.

In the plasterboard industry, the ultrafine mill can scatter and lift the desulphurized gypsum slag cake with water content less than 12% by the rotor of a ultrafine mill. Moreover, it can be fully heat exchanged with the 550 ℃ hot air introduced to form the material with water content of less than 1%. The material enters the rising pipe from the exhaust pipe and is carried away by hot air into the next process. The ultrafine mill can also be used in the cement industry for and crushing carbide slag in filter cake and environmental protection field.

The following are the advantages of cement vertical mill in processing cement materials:

1.The efficiency of vertical grinding mill grinding of cement

The internal analyzer of the vertical grinding mill can distinguish whether the grinding fineness of the finished product is up to the specifications of the equipment. The analyzer will be re-expanded and replaced in the mill, thus repeating the process to ensure that the material can meet the required fineness requirements. In order to test the efficiency and flow of the milling machine, it is necessary for customers to purchase an on-site testing machine for ultra-fine mill equipment.

2.Material Strength

The strength of different materials is different, and the suitable strength of ultrafine grinding can be selected according to different needs. SBM Mining Machinery Co., Ltd. vertical grinding mill can better meet the production needs of different customers in different grinding fineness range. If some materials are too strong, they need to be grinded after grinding and crushing to ensure grinding and grinding efficiency.

1. Material viscosity:

The higher the viscosity of materials, the easier adhesion. The material with high viscosity will stick to the inner wall of the sand making chamber in the sand making machine. If it cannot be cleaned in time, it will seriously affect the working efficiency of the sand making machine and seriously affect the normal work of the sand making machine. Therefore, when selecting materials, it is important to note that the viscosity of materials should not be too high.

2. Composition of materials:

The more fine powder there is in the material before sand making, the more influence it will have on sand making, because these fine powder will adhere easily and affect the transportation. Therefore, for the material with a large amount of fine powder, a screening should be carried out in advance to screen the fine powder from the material as far as possible, so as not to affect the normal operation of the sand making machine.

3. Humidity of materials:

If the water content is high, it is easy to adhere to the material when it is broken in the sand making machine, and it is also easy to block in the conveying process, resulting in the reduction of sand making capacity. In order to solve this problem, the humidity of materials should be strictly controlled when selecting materials. If the humidity of materials is too high, sunshine or air drying can be adopted to reduce the percentage of moisture in materials.

It is divided into cylindrical vertical roller mill, roller vertical roller mill, disc vertical roller mill, ring vertical roller mill, in addition, have rotor vertical roller mill, belt vertical mill, conical vertical roller mill, but these types of vertical roller mills have been used less.5 Constant, alternating, pulsating magnetic field vertical roller millAccording to the way the magnetic field strength changes:

1) Constant magnetic field vertical roller mill. Using a permanent magnet material and a direct current electromagnet, a solenoid, or the like as a magnetic source, the magnitude and direction of the magnetic field strength do not change with time.

2) Alternating magnetic field vertical roller mill. An electromagnet that is connected to an alternating current is used as a magnetic source. The magnitude and direction of the magnetic field strength changes over time.

3) Pulsating magnetic field vertical roller mill. An electromagnet that simultaneously transmits direct current and alternating current is used as a magnetic source. The magnitude of the magnetic field varies with time, but the direction does not change. And pulse
