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.

What's the Special Role of Vibrating Screen Bouncing Ball?

 When the vibrating screen works, have you ever noticed that the bouncing balls beat up and down on the sieve mesh? Why this phenomenon occurs on the sieve mesh? What's special role of bouncing ball? Today we will take a brief look.
These bouncing balls are an essential part of vibrating screening machines.Its role is beating the sieve mesh up and down avoid adhesion material blocking the sieve mesh which can improve screening efficiency and accuracy.
ball deck
Bouncing balls are generally divided into different diameters: φ10, φ15, φ20, φ25, φ28, φ30, φ40, φ50, φ60 and so on, commonly used ones are φ25 and φ28 , φ40, φ50and φ60 mainly used for mine vibrating screen.
According to the material,bouncing ball can be classified into several types: rubber ball, silicone ball, PTFE ball bouncing, according to different materials of bouncing balls, the application and function is also different.
Natural rubber bouncing ball:it is suitable for general material screening process;
Silicone bouncing ballgood elasticity., mainly used for food, medicine and other materials screening;
PTFE bouncing ball : It can soak in the oil , mainly applied to oily liquid materials screening.
The bouncing balls should be selected based on different material properties to meet customer requirements in different conditions. Though bouncing ball is a small accessory, it is the key to solve the problem of screening.

The difference between the Conical self-aligning roller and the Friction transfer roller

Tapered self-aligning roller is similar with Friction self-aligning roller in structure which are mentioned when introduce the belt conveyor, their purpose is protecting belt and preventing belt deviation. However, in the process of actual use, there is a big difference between them.
The main difference:
tapered-self-aligning-roller
1.Stability performance: these two kinds of roller have their own advantages and disadvantages. Tapered self-aligning roller provides a more stable transport environment for belt and material, but since the tapered roller with a certain angle, if carries the material for a long time, it will increase the radial offset of roller. While friction self-aligning roller has a stable structure so that it can carry material for a long time and won’t be influenced. but there is a certain angle between belt and roller due to design of friction pulley, the joint degree of friction self-aligning roller is lower than tapered self-aligning roller, which will reduce the stability performance of belt conveyor.
2.Friction coefficient: concerning this aspect, tapered self-aligning roller has advantage over the friction self-aligning roller, tapered self-aligning roller has a special body design of roller, it could extremely increase joint degree of belt and roller to make the belt adapt to tapered roller, it also greatly reduce the force of friction.
friction-self-aligning-roller
3.Sealing Performance: the sealing performance of friction self-aligning roller is better than tapered self-aligning roller, the friction one adopts the design with independent installation of the friction pulley to promise a good sealing performance, however, because tapered self-aligning roller has a different diameter of pipe, it increase the difficulty of seal, meanwhile, performance of seal is also reduced.
4.Production cost: the structure and technology of tapered self-aligning roller are much simpler, so the cost is low, but if in the long run of using, the friction self-aligning roller is more stable and durable.

How to Maintain Motorized Pulley and Keep it Servicing Longer Time?

Are you in trouble with maintaining and repairing motorized pulley when operate the belt conveyor? Come and check this article ,we are sure you will get a satisfied solution !
1. In order to create a good condition for normal operation, please check the surrounding environment, fastening bolts, oil leakage, the cable before each start-up.
2. Please start a new pulley with inching running, then it will turn into normal gradually, please check the machine vibration, noise, and temperature heating of each operating component after running for 10 minutes.
3. If oil leakage happens to motorized pulley, please pay attention to check two parts: one is oil seal, check it whether has wear and tear or deformation phenomenon, if any, please replace the cage oil seal timely; the other one is that the air outlet can’t be blocked, if there is blockage, the deposition of dust, grease and sundries shall be removed as soon as possible to ensure smooth access.
4. Regularly check the oil level in the drum is an important part of the daily maintenance, besides, regulation of the oil level height is one of the conditions to ensure the normal operation of the pulley. Inspection methods can be referred according to operation manual.

Working Principles
Belt conveyor is composed by two endpoint pulleys and a closed conveyor belt.  The pulley that drives conveyor belt rotating is called drive pulley or transmission drum; the other one–only used to change conveyor belt movement direction–is called bend pulley. Drive pulley is driven by the motor through reducer, and conveyor belt dragging relies on the friction drag between the drive pulley and the conveyor belt. The drive pulleys are generally installed at the discharge end in order to increase traction and be easy to drag. Material is fed on the feed-side and landed on the rotating conveyor belt, then rely on the conveyor belt friction to be delivered to discharge end.

fixed belt conveyor for coal
►Application
Long distance belt conveyor can transport bulk materials or bagged goods, such as stone, sand, coal, concrete, cement, gravel, fertilizer, mineral ore, limestone, coke, sawdust, wood chip, bulk material, grain, corn flakes, carbon black, component/part, etc.
Components of Belt Conveyor
Main components of a belt conveyor are:
   1.Belt is used for moving and supporting surface on which the conveyed material rides. It is the tractive element. The type of belt used need to depend on the nature of materials to be transported. 
   2.Idlers are the supports for the carrying and return stands of the belt.
   3.Drive that imparts power to one or more pulleys to move the belt and its loads.
   4.Structure is the support and maintains the alignments of the idlers and pulleys. Besides, it also supports the driving machinery. 
Other components included: 
   5.Loading chute or feeder chute that organizes the flow of material and directs it on the belt conveyor.
   6.Take-up device which is used to maintain the proper tension of the belt for effective power transmission.
   7.Belt cleaner that keeps the belt free from materials sticking to the belt.
   Tramp removal device, which is optionally used in case the conveyed material bears the chance of having tramp iron mixed with it and subsequent handling of the material, demands its removal. 
   8.Continuous weighing device for constantly measuring the load being carried by the conveyor belt.
   9.Discharge chutes to guide the discharged projectile to subsequent conveyor or other receiving point.
   10.Surge hopper and feeder, which is essential for supplying material to the conveyor at uniform rate when the supply of material is intermittent.
