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.When the vibration motors’s inclined angle is increased 
the horizontal stress of the materials on the screen will be decreased, the forward speed of the material will be decreased , the exciting force on the screen will be decreased, and all of these conditions will result in low screening efficiency and affect the screening effect. 

 

2.When the vibration motors’s inclined angle is decreased
The horizontal stress of the materials on the screen will be increased, the forward speed of the material will be increased as well . Although this can achieve in high screening efficiency, but it cannot achieve in good screening effect.

After few times of research work and lab testing by PK machinery’s engineer, the most efficient inclination angle of the vibration motors is at angle of 45 degrees which can make the vibration motors work in best performance by giving out high screening effect and efficiency.

The Reasons Why Screw shaft of Screw Conveyors Stops Rotating

 Generally, if screw shaft of screw conveyors stops rotating, it mainly caused by the following three reasons:

 

1. The size of conveying material is too big and can't pass through the intermediate bearing, material resistance here is too big which will lead to motor overload and stop operation. Then you must clean up the material inside the screw conveyors .
2. The place of intermediate bearing resistance is large, sealing damages. Material will go into the bearing which will lead to bearing stops rotation or bearing damages.

 

3. Bearing of gear motor burns out.
If the reducer bearing temperature rises too fast after start-up and along with abnormal noise and reducer vibration, at this time, you should stop the machine quickly and the reason may be caused by the following aspects:
1) If the reducer output shaft bearing temperature is high ,but input shaft bearing temperature is normal. This is because the screw shaft centerline offsets or reducer output shaft bearing damages, or head and tail bearing loosens. Here you need to loosen the coupling between reducer output shaft screw shaft, correct and install.
2) If the bearing temperature of reducer output shaft is normal, but input shaft temperature is high. This is because the motor fixed components loosen or reducer output shaft bearing damages, you need to loosen the coupling between reducer input shaft and the motor, correct and install.
3) If both of reducer output and input bearing temperature are too high. This is due to the loosening of fixed bolts on reducer or both ends of reducer bearing burn out, here you need to loosen the coupling on both sides of reducer ,correct and install.

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?

Henan Pingyuan Mining Machinery will explain 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 ofcircular 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
