What Factors Lead to Inflexible Rotation of Conveyor Roller

In our daily use of conveyor roller, inflexible rotation phenomenon may occur during the operation, what factors lead to inflexible rotation of conveyor roller? Let’s see the following two parts:
The manufacturing quality of belt conveyor idlers
The manufacturing problems of belt conveyor mainly are bearing lacks of rigidity, difficult to ensure the roller assembly accuracy , which restricts the operation flexibility.
Sealing, lubrication and maintenance
Because of belt conveyor working environment is relatively poor, generally, operation site is full of dust, and the bearing sealing form has big influence on roller operation flexibility. If sealing poor, dirt can easily enter into the bearing inner which causes inflexible rotation; in addition, if bearing grease adopts common calcium base grease ,it is easy to change color and become dry, can't reach a very good lubrication effect.

How to choose the suitable vibration motor for the vibration machine?

Vibration motor has many types and models with a wide application,it is usually applied with the feeder, vibrating screen combination. The vibration motor is very important in the vibration machine. It directly determines the working efficiency of the vibration machine.The vibration mechanical vibration motor selection steps are as follows:
A.According to the operating requirements, confirm the required vibration of the frequency (r/min) and the amplitude Ym (mm).
Such as the six vibration motor (n=960r /min) can drive the vibration chute, vibration feeder, vibration mill, vibrating screen etc.
B.According to the structure of the vibration machine itself, get the vibration weight G (kg) and calculate the required vibration force Fm (N) .
C.According to the vibration of the operation to get Fm, you can get the model of the vibration motor, please pay attention to the exciting force FH is larger than Fm.
D.Design the overall structure, and calculate the actual vibration parameters, after the calculation, if the vibration motor is too large or too small, motor model should be re-selected.
E.Design of vibration isolation system.

According to the information offered by our customer, we provided three kinds of conveyor rainproof cover to them. One is matched with 800mm belt width conveyor, another is matched with 1000mm belt width, and the last one is matched with 1400mm belt width. Meanwhile, the quantities of conveyor rainproof conveyor are 490 pieces, 110 pieces, 40 pieces respectively. Also, they have the same thickness that is 0.8mm.

Type and Function of Fixed Belt Conveyor Roller

Roller is used to support the conveyor belt and carry of the material, to ensure the stability of theconveyor belt.
In general, the fixed belt conveyor roller is the following:
1.Trough roller: it is also known as carrying roller which is used for carrying bulk material;
2.Parallel roller: parallel upper roller is used for carrying materials, parallel lower roller is to support the return branch of the conveyor belt;
3.Self-aligning roller: it includes taper aligning supporting roller and friction aligning roller which are mainly used for adjusting the belt deviation to avoid S-shaped, so as to ensure the stable operation of conveyor belt;
4.Impact roller: it is installed in the lower part of the conveyor belt, which can reduce the impact of the conveyor belt to extend the service life of the conveyor belt;
5.Return roller: it supports the conveyor belt of lower branch,including parallel type, V type, inverse V type,etc. V and inverse V type roller can reduce the conveying belt deviation possibilities;
6.Transition roller: it is installed between the drum and the first set of roller, which makes the conveying belt gradually turns from through shape into or flat shape and reduce additional stress of the conveying band edge turns to trough shape due to the expansion, at the same time,it can prevent the material spreading phenomenon of conveyor belt.
In addition, the comb type roller and screw roller, which can remove the sticky material on conveyor belt to keep the conveyor belt clean.
