How Much Do You Know the Vibrating Screen Bouncing Ball?

As we all known,bouncing ball is an important part of the rotary vibrating screen.Bouncing ball has a widely used in different aspects.Today we will importantly introduce you the bouncing ball which is used in the industry.
Bouncing ball, good elasticity, wear-resisting, is one of indispensable spare parts in the vibration equipment.It is installed in the vibrating screen in the middle of the perforated plate and the steel grids, by cycling beat subnet work (network) on adhesion of materials, to increase the rate of material through the net and screening production.

screen mesh manufacture

According to the different material properties, bouncing ball can be divided into the following kinds:
1.Natural rubber bouncing ball: suitable for general material screening;
2.Silicone elastic ball: it has the advantages of good elasticity, mainly used in food, medicine and so on material screening;
3.Ptfe rebound: it has the advantage that can be soaked in oil, mainly is suitable for the screening of oily liquid.
In addition,because the bouncing ball has different function, so according to the different needs of customers, manufacturers need to choose different bouncing ball.

Advanced Technique Improvement of Gyratory Screen Mesh

In order to meet the requirement of our New Zealand clients who ordered 4 sets of gyratory screen with 2 layers, our screen mesh technique gets a further improvement.
This screen is used for sieving glass, the screen mesh design is different from previous design due to the special characteristics of material, the sealing performance of screen mesh is further improved.
Air hole buckles are embedded at the edge of screen mesh which can also achieve the fixation function to prolong the life span of gyratory screen mesh.
A support mesh is added under the fine screen mesh, it can not only increase the elasticity of screen mesh, but also play a role which can prevent material from piercing through the screen mesh.
Combining innovative thinking and creative power of our R&D Department with the feedback or brilliant suggestion, we are sure we will move a big step in improving our technique. Further information please click:www.pkmachinery.com  

Four Advantages of Linear Vibrating Screen with an Inclined Angle

Linear vibrating screen is widely used in mining, coal, refractory, metallurgy, building materials and other industries etc. PK Machinery can customized according to the client’s requirement and site space, such as the inlet and outlet location, vibrator motor installation location and linear vibrating screen can be inclined.
1. The motor angle of inclined linear vibrating screen can be adjusted freely, you can also enlarge the vibration source to get a amplitude which can meet the requirement of material screening.
2. The linear vibrating screen with an inclined angle can increase the screening production and improve production efficiency.
3. According to different material properties, the material can be sieved quickly due to the inclined angle of linear vibrating screen, it also can reduce the damage and friction of the screen mesh which brought by material.
4. When the angle is 15 °more than parallel, material are input as obtuse angle, it will increase the service life of the screen mesh effectively.

How to deal with the Linear Vibrating Screen discharging inclined to one direction

   If the linear vibrating screen handing material poorly and discharging inclined to one direction, what should we do?

   The most prominent feature is no powder dispersion.

  1. Linear vibrating screens handing material low efficiency. Generally, the irrationality installed of the vibration motor can cause low efficiency handing material of the linear vibrating screen. Normally the supplier of the linear vibrating screen will send the technical personnel to help install the screen. Their key responsibilities are guide the users install and debug of the screen. While, owing to the screen vibration some parts of the screen will happen loose during the operation. At this time, users are required to maintain the vibration screen regularly. If have some difficult problems should contact the manufacturer promptly. In order to avoid unnecessary losses, please don’t disassembly the screen privately! (Contact us :  info@pkmachinery.com)
 

 

   2. The possible reasons that caused the linear vibrating screen discharging inclined to one direction are as follows: 
 

  1) Feeding unequally. When using the linear vibrating screen to screen the material, we should try to feeding equally to avoid the screen discharging inclined to one direction.
 

  2) The installation base surface and spring seat place change.
 

 

   3) Weight error of the screen itself, the center of gravity location inaccuracy
 

   4) Whether vibration exciter location and swing eccentric block either side is on balance
 

 

  5)  The shock absorb spring is inconsistent, some of them damaged.
 

  6) Screen box transmutation.

Common Troubleshooting Methods of Vibration Motor

1. after connect the power supply, motor is unable to start, please check:
(1) if power supply is lack of phase;
(2) if motor is loss of phase;
(3) if protective cover is damaged or rub eccentric block.
2. after start-up, there is big motor noise or motor heats, please check:
(1) if the contact surface roughness of vibration machine and motor foundation is in line with the installation requirements;
(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. 

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.
