(2)if the anchor bolts are not tighten up ;
(3) if the vibration acceleration is in line with the requirements;

3. after the adjustment of eccentric block, amplitude changes abnormally please check:
If eccentric block on both ends of the rotor axis is symmetrical;
4. when two vibrating motors of vibration machine vibrate at the same time, if its phase does not conform to the requirements, please adjust the phase sequence of the single unit, don't adjust the total phase sequence of two vibrating motors.

What is the Applicable Material for Drum Screen

Drum screen is a kind of cylinder revolving screening machinery that relies on gravity, its working principle is different with rotary vibrating sieve, linear vibrating screen, drum screen can generate strong exciting force, so if dealing with the proportion of lighter materials, it is not suitable for drum screen, the screen is easy to get blocked due to the irregular shape material, and the most important is the screening effect is bad, so what is the applicable material for drum screen?

 

Drum screen also is often used in mining, sand ,gravel industries, common screen mesh size can be larger than 5 mm, the smallest mesh size should larger than 3 mm, if the mesh size is smaller that is the wire mesh is small ,the service life will be shorter, besides, the drum screen doesn’t do a good job for on sieving fine material and the sieving efficiency is not very good.

 

Except for sandstone, drum screen is also more commonly used for granular material screening, such as: chemical fertilizer, ceramsite and so on. The sieving efficiency is good and easy to handle large-scale capacity. 

How to Maintain Vibrating Screen in Summer

In summer, excess temperature is a hidden danger of daily operation for vibrating screen, generally speaking, working requirements of the environment temperature is not more than 40 ℃, so during the daily operation of vibrating screen, what we should concern about is not only the process of production, but also the degree of temperature that the vibrating screen can bear.

For the outdoor working conditions, a anti-sunshine net or cover should be set up for the vibrating screen.

Long-time sun exposure not only make the machine easy to get aging, but also cause the vibrating screen can not work normally due to the high temperature which will affect the screening efficiency and quality, it will even lead to a serious component damage, such as the damage of vibration motor.

For the indoor working condition or vibrating screen works in an ore processing plant, please pay attention to the adjustment of the indoor temperature, as well as the ventilation and the permeability, generally, a good working temperature is not more than 40 ℃.

The Classification and Function of Rotary Vibrating Screen Sealing Ring

 As we all know, rotary vibrating screen does a good job in food, chemical, ceramic, paper making, metallurgy industries, as well as its components sealing ring which plays an important role to ensure the sealing performance of rotary vibrating screen.

Generally speaking, sealing ring can be divided into two types: U type and V type, it is mainly used for screen frame, net rack and dust cover to ensure better sealing performance and prevent leakage of material, at the same time it can reduce the destructive force to screen frame that rotary vibrating screen brings in vibration.

 

Sealing ring is commonly made of rubber, silicone and polyurethane, if there is no special requirement, it will be equipped with rubber sealing ring; Silicone and polyurethane sealing rings are mainly used for materials with special properties, such as high temperature, oil, corrosive materials. Among three types of sealing rings, the silicone sealing ring has a better sealing effect.

 

Daily Operation and Maintenance of Gyratory Screen

Gyratory screen (similar with Rotex screener) is a high precision standard of fine screening machine, which is mainly composed of screen box, driving device, screen frame, support and vibration damping device, gyratory screen structure is compact, it is mainly used in screening operation like chemical, food processing, refractory materials, building materials industries. Here PK Machinery will make a brief introduction of gyratory screen daily operation and maintenance:

 

1. check if all the components are normal, whether the fasteners are loose or not, especially the vibration motor; 
2. in the process of operation, please stop the machine at once and inspect if any abnormal sound is found , don not put into operation unless eliminate the failure; 
3. it is an initial stage that motor running accumulated within 100 hours, during this period, please fasten the foundation bolt regularly; 
4. you can shut down the gyratory screen after confirming the material inside the screen is empty ,so as to avoid material blockage; 
5. check the screen and clear the screen mesh regularly, check tension condition of screen mesh and see if there is degree; 
6. after about 200 hours of operation, please lubricate the vibration motor bearing, add lubricating oil inside the bearings, the grade is 1# calcium base grease.

Maintenance of Vibration Motors of the Linear Vibrating Screen

The Linear Vibrating Screen requires limited preventive maintenance. However, there are a few steps to follow to ensure years of trouble free service. In general, you need to complete a common sense inspection of the structure, vibration motors, and so on. On a daily basis. Daily inspection on the screens for wear or holes is needed. If damages occur, repair or replace as necessary. The vibrator motors must be greased with lubricating oil. Over greasing causes overheating of the bearings and this must be avoided. Besides, use only prescribed grease in vibrator motor. If different grease is used, vibrator can be damaged and warranty will be voided. Use only prescribed amount of grease to lubricate vibrator. Too much grease will cause the bearings to overheat and result in premature bearing failure.

The Advantage of using Wooden Screen Frame for Vibrating Screen

Vibrating screen wooden screen frame and plate have the advantages of sufficient strength, high opening hole rate and less blockage etc. When vibrating screen vibrates, the different shapes and sizes materials will pass through the screening plate under the action of vibration, material separation in order to achieve classification purpose.
Vibrating screen wooden screen frame and plate is commonly used for linear vibrating screen, it is convenient to replace screen mesh, you can also add bouncing balls which will increase the rate of passing through the screen mesh to prevent the blockage effectively, it is suitable for powder material screening. Wooden screen frame includes cypress screen frame, white pine screen frame and the Korean pine screen frame. The first one is an economic, the cost of the last two is 3 times higher than first one.

Wooden screen frame is an important working parts to complete the screening process, and it should be selected reasonably as per the requirement of screening equipment and working environment in order to achieve the best effect.
