Energy saving and environmental protection of grinding mill

At present, energy conservation and environmental protection has become the main theme of the development of the times, only with energy-saving, green, environmental protection of mine grinding mill can be based on the market, so as to be favored by more consumers. Therefore, many processing plants have carried out optimization and transformation, making more and more machinery and equipment in line with the trend of energy saving, green and environmental protection. In order to comply with the development trend of the times, we have optimized and upgraded the environmental protection performance of milling equipment to make it more in line with the requirements of national green environmental protection.

First of all, the equipment has a high degree of coordination between the various structures. It operates under negative pressure, with less dust and lower noise.

Secondly, the sealing of the equipment is more rigorous and reasonable, and there is little dust overflow in the operation process. The design of noise reduction device reduces the noise level of the equipment.

The design of dust-proof and explosion-proof device can reduce the dust emission to zero, and there will be no dust explosion accident, and the safety is better.

In addition, compared with ordinary milling equipment, the energy consumption of the mill is reduced by more than 30%, and the power consumption is also less, which has a good effect of energy saving and consumption reduction, which can save a lot of investment costs and obtain greater benefits.

According to experts, this grinding mill not only has significant energy saving and environmental protection advantages, but also has reliable quality and performance. Its grinding roller and ring parts are made of super wear-resistant materials on the market, with stronger toughness and firmness, better quality and longer service life. Moreover, the particle size of the material grinded by the equipment is very fine and even, the product has high precision, high recovery rate, there is no waste of resources, and the income is higher.

After the grinding mill is applied to the processing plant, its unique energy-saving and environmental protection performance has been loved by users, which improves the production environment of the processing plant and achieves good grinding effect. It can be called the masterpiece of the green era.

Some skills to improve the service life of vibrating screen

Vibrating screen is a kind of filtering mechanical separation equipment for mud solid phase treatment, which is widely used in mining, building materials, transportation, energy, chemical industry and other industries. It is used for screening of material classification, washing, dehydration and demineralization. The vibrating screen is mainly divided into linear vibrating screen, circular vibrating screen and high frequency vibrating screen. The vibrating screen is composed of vibrator, screen, suspension device, transmission device and other parts. The screen is an important part of the vibrating screen. However, the damage of the screen is too fast, which is one of the common problems of the vibrating screen. What leads to the short service life of the screen? How to improve its service life? Today, experts will make in-depth analysis for you.

The main reasons for the short service life of the vibrating screen are clay accumulation, wrong direction of the motor, loose fit between the screen and the screen frame, and poor quality of the screen. In view of these problems, we will further analyze them.

一、 Clay Accumulation

The vibration amplitude of vibrating screen is too small to effectively overcome the viscous force of clay, which leads to the accumulation of clay on the screen and rapid damage to the screen.

Resolvent:

1. Increase the vibration amplitude;

2. The spraying water is used to wash the screen and clay to reduce the viscosity, but this method is only suitable for the occasion where water is allowed to be added;

3. The screen angle at the end of sand discharge port is adjusted downward to facilitate the discharge of materials by gravity;

4. Change the mesh number of screen or adjust the flow rate of single screen, so that the material can be discharged smoothly.

二、 Motor Steering Error

When adjusting the direction of motor, according to the past experience, the field operator thinks that as long as the material moves forward, this method is only applicable to the linear screen. If the motor rotates to the inside by mistake, the throwing angle is 45 ° forward, but the material has the force to roll backward. At this time, the forward moving speed is much slower, and the material stays on the screen for a long time, and even the material cannot be discharged.

Resolvent:

1. When the screen box is running, press the stop button of the electric control box. At this time, the vibrating screen will stop slowly. Observe the elliptical track formed by the small points on the side plate during the operation of the vibrating screen, and roll to the sand outlet to make the correct direction;

2. Remove the vibrator cover and check whether the eccentric shaft rotates to the outside;

3. Replace any two phase lines in the incoming power supply of the electric control box and sprinkle some sand on the screen. The one with faster sand discharge speed is the right direction.

三、 The screen does not fit tightly with the screen frame

After the rubber strip supporting the screen is worn, the screen can not contact with it reliably; the screen screen is not reasonably tight.

四、 Poor screen quality

Generally, there are upper layer and lower part of the screen. The two layers are required to fit closely. If the screen technology is poor, when the stress layer at the bottom of the screen is tight, the screen layer is not tightened, and the throwing force of materials is greatly reduced during operation, so the screening and discharging can not be carried out smoothly. Solution: replace the screen with high quality.

5 ways to prevent corrosion of sand making machine

Sand making machine is an important equipment in artificial sand production line, so how to prevent corrosion and improve the production efficiency of sand making machine, the following are some suggestions to prevent corrosion, welcome your reference:
Before Use:
1. Reasonable Selection of Materials
Select the appropriate material according to the circumstances of the environmental medium. Select materials to eliminate the problem of selection.
2. Cover Protective Layer
In the sand making machine surface covered with a layer of different material, change parts surface structure, the metal and medium to isolate corrosion prevention. For example, metal protective layer, nonmetal protective layer, coating and so on.
3. Electrochemical Protection
River gravel sand electromechanical chemical protection is to be sand making equipment through polarization current, to eliminate the potential difference. Through these protective measures, will make the gravel and making a machine from corrosion, reinforced sand ability, prolong the service life of equipment, to create more wealth for you.
When Used:
1. to prevent wear and tear, to make reasonable use of the machine when used, and to check the easily worn parts in time.
Check-in time to improve the production efficiency of the machine.
2. on the gravel sand making machine parts timely check. There is a positive observation, recording and making a corresponding solution.
After use:
The machine is properly placed in order to prevent the damage to the protective film of the machine and the anti-corrosion ability of the machine.
