What is the method and maintenance steps of Vibrating Screen at low temperature in winter?

Dec. 27, 2019

In December, the winter process in the northern part of China has begun. Low temperatures will not only cause certain harm to the human body but also have a great impact on the operation of mechanical equipment. The same is true for Vibrating Screen. If you work in cold temperatures for a long time, there may be various problems with the shaker. This affects the accuracy and efficiency of screening and then affects the efficiency and quality of product production. It must not be underestimated. There must be effective methods to help the vibrating screen. The moving sieve is a sieving equipment that can be classified, dewatered, declined, dislodged, and sorted. The vibration of the sieve body is used to loosen, layer and penetrate the material to achieve the purpose of material separation. The screening effect of the vibrating screen has a great impact not only on the value of the product but also on the efficiency of the next operation. Xiaobian thinks it is very necessary to let everyone know what precautions and maintenance methods of the vibrating screen machine with low winter temperatures are going to go before the temperature reaches the minimum.

What precautions should be taken when working with Linear Vibrating Screen at low temperatures?

The impact of the low temperature in winter on the vibrating screen is mainly reflected in the wear of the vibration motor and various parts of the equipment. The vibration motor requires environmental temperature between -15 ℃ ~ 40 ℃, and it will be bagged at low temperature for a long time. As a result, the start-up time of the vibrating screen becomes longer and the start-up speed becomes slower. It may also cause the lubricants in the screens to freeze and cause the wear of the parts to increase. The following 3 situations are common types of vibration screen failures that may be caused by low temperatures in winter:

Possible failure of the shaker in low winter conditions:

1. Cannot run

When the sifter fails to run normally, the motor and bearings run poorly due to the low temperature. This problem usually occurs when the vibrating screen is installed outdoors without protective measures. To solve this problem, we can install a protective cover, take antifreeze measures at the motor and bearing parts, and add antifreeze to the motor and bearing parts to prevent the oil from thawing;

2. Low screening efficiency

This problem is mostly caused by the sieving of liquids. In winter, the temperature is low, icing and sticking to the screen will occur when screening tax-containing materials, thereby reducing the screening efficiency. The solution to this problem can increase the liquid temperature of the material within the allowable range (it is generally better to keep it at 10 ℃). After the screening work is completed, the screen is cleaned in time to ensure that no liquid remains on the screen surface;

3. Frequent failures

If the quality problem of the sieve machine is eliminated, the frequent solution is to strictly follow the operation manual. Regularly inspect and maintain the sieve machine, and keep a record of the shift during the shift. The maintenance of the vibrating screen in the severe cold environment is very important. Only the vibrating screen with good quality can withstand the test of the severe winter. We are Vibrating Screen Manufacturer, welcome to consult.
