The Development Trend of Vibrating Screen

The Development Trend of Vibrating Screen

With the higher and higher requirements, the development of vibrating screen reaches a new stage. Here we will introduce you the development trend of vibrating screen.

Vibrating screen is widely used in mining, coal, smelting, building material, refractory material, light chemical, medicine, food etc.

With the higher and higher requirements, the development of vibrating screen reaches a new stage. Combining the domestic and abroad situation, it can be divided into some aspects as follows:

1.To develop in the direction of high efficiency and large output 

Development of industrial modernization process which increases enterprise scale and production capacity greatly, so it needs to match with an efficient high-throughput screening machine.

2.To develop in the direction of standardization, serialization and generalization 

This is a good way to guarantee the quality and reduce the cost , it also provides convenience for designing and organizing specialized production.

3.To develop in the direction of stronger vibration strength

The vibration of vibrating screen is strengthened gradually in order to improve productivity and screening efficiency.

4.To develop in the direction of light ,environmental protection and simply structure

Now the structure of vibrating screen is much more simple than previous one, it is more convenient to replace the screen mesh and will save a lot of time.

Henan plain mining machinery co., LTD is specialized in manufacturing screening equipment, lifting equipment and conveying equipment , with abundant engineering design experience, professional technical ability and strict fabricating specification, PK Machinery is always walking at the forefront of this developing trend!

Maintenance Notes for Circular Vibrating Screen

Maintenance Notes for Circular Vibrating Screen

Do you know how to maintain circular vibrating screen when it is breakdown during operating? Today, Pk Machinery will introduce some maintenance notes for you.

1. Always keep the circular vibrating screen working in a clean and sanitary environment.

2. The bearing on both ends of the motor should be lubricated with anti- high temperature lubricating grease, in the first month, please lubricate once a week.

3. Check flange bolts on both sides of motor, the bolts which fix the mesh and the support connecting bolt shouldn’t have loose phenomenon.

4. The circular vibrating screen should be maintained every half year.

A. clean the vibrator and add grease for all lubricating points.

B. check the abrasion condition of screen mesh, if any damage , please maintain and replace timely.

 

5. The circular vibrating screen should be maintained and repaired every year. 

A. Open the motor terminal box ,check the insulation between the wires and clean the dust.

B. Add grease on all lubricating points.

C. check each part of the circular vibrating screen and abrasion condition of screen mesh, if any damage please maintain and replace timely.

E. After finishing all the work, a trial run is also required. 

What Should We Note During the Operation of Gyratory Screen

What Should We Note During the Operation of Gyratory Screen

During operation of gyratory screen, there is something that we should mention. This article will introduce some necessary notes before operating machine.

Gyratory screen is similar to rotex screener, it is designed with gyratory motion which can obvious improves the distribution of the material. Applicable material includes urea, potash, fertilizer, activated carbon, pellet, ceramic powder, sugar, salt, starch and fireproofing material etc. Here PK Machinery will introduce necessary notes before starting up the screen.

1. Check the fastened part, safe protection device and lubrication before start-up.

2. Test run without load first for about 3-5mins to see if the rotation direction meets the requirement.

3. Feeding material with normal operation once non-load test run is normal,

4. Check the material discharging condition during running, if any blockage is found, please solve it timely.

5. Check the material distribution on screen mesh is uniform or not, if necessary, stop machine and adjust.

6. If there is abnormal noise or vibration that you have to stop the gyratory screen, please stop machine at once, only when the trouble is eliminated, then you can start up.

7. If gyratory screen is operated in a production line together with other equipment, please start up downstream equipment, then start up the upstream equipment.

What is the Impact on Adjusting Vibration Motors Inclined Angle of Linear Vibrating Screen

What is the Impact on Adjusting Vibration Motors Inclined Angle of Linear Vibrating Screen

Linear vibrating screen utilizes vibration motors as vibration power driving the material jump up on screen mesh and do linear movement. Besides, concerning the materials like crushed stone and sintered ore which are difficult to sieve, you can change the material residence time by adjusting the inclination angle of vibration motors according to the production requirements to achieve the purpose of higher screening performance, however, what should we do to adjust the vibration motors according to the needs? Today PK Machinery will introduce the impact on adjusting the motors inclined angle of linear vibrating screen:

 

1. The vibration motors inclined angle increase: generally speaking, the motors inclined angle will be 45 degrees, if increase angle, the horizontal stress of oversized material will decrease, material moving forward speed will be slow, so we can see the screening performance is great.

2. The vibration motors inclined angle decreases: Motor Angle decreases, he horizontal stress of oversized material will increase, material movement forward speed gets fast, so we can see the screening efficiency is great.

 

 

Application Analysis of Calcium Carbonate Rotary Vibrating Screen

Application Analysis of Calcium Carbonate Rotary Vibrating Screen

The sealing performance of calcium carbonate rotary vibrating screen is pretty good, non-blocking design and precise screening. Besides, you can also choose ultrasonic vibrating screen instead of common rotary vibrating screen in order to achieve more accurate screening performance, the screening accuracy even can reach 500 mesh.

In the process of production of calcium carbonate, it mainly includes light calcium carbonate and heavy calcium carbonate, the production process of two kinds of calcium carbonate is the same during crushing and screening. When screening the calcium carbonate, the output rate is designed according to manufacturing production rate per hour, the screening amount is calculated as per the material amount after crushing, the general selection of material granularity is around 100 mesh and the main selection specification is 60 mesh, 80 mesh and 120 mesh etc. In addition, the mesh size is also selected according to the needs of users. In the process of screening, rotary vibrating screen is the best screening equipment, the screen mesh can be replaced with the previous required mesh size in order to achieve the screening requirements.

Why Choose Rubber Spring for Circular Vibrating Screen

Why Choose Rubber Spring for Circular Vibrating Screen

1. It can produce various different shapes and dimensions of the rubber springs which is compact and space saving.

2. Rubber Spring is with rubber elasticity coefficient compared with metal product, and the hardness can be changed in a larger scope, so changing the rubber hardness can make different stiffness spring, that means the stiffness can be chosen with wide scope even the same shape of rubber spring. 

3. In addition, rubber spring of circular vibrating screen can also accept with shear deformation and austerity deformation.

4. The internal friction damping of the rubber spring is much bigger than the metal spring, so the rubber spring of circular vibrating screen machine stops and passing through resonance section, the amplitude of rubber spring is smaller than the helical metal spring ,so we choose rubber spring due to stable amplitude and lower energy consumption.

          

5. Rubber spring transmission noise resistance is much bigger than the metal spring, so the sound insulation is better and working noise is smaller. Above all, rubber spring of circular vibrating screen characteristic is very outstanding and it is widely used for vibrating screen equipment.
