How to select conveyor cover?

Application and Working Principle：
YD Conveyor Covers is well known as conveyor belt hood and used to protect transported material and conveyor belting, idlers and structure. Effectively they improve personnel safety; reduce loss of material to wind and stop grime and rain from damaging the idlers and belt.
YD Conveyor Covers is mostly used in power plant, cement factory, iron and steel factory, chemical factory, coal, port, jetty, mining and other enterprise. Our company provides fixed-closed type and open type. The color of the rain covers are mainly in blue, grey and white, and red (depend on client’s need).

Selection guidelines
1). Please tell us your belt conveyor’s width____mm and length____mm;
2). If possible, please indicate the opening width____mm of the conveyor cover; 
3). Please indicate the thickness of the cover you required____mm;
4). Every piece conveyor cover’s length is 970mm, except overlap installation, the effective length is 900mm. 
5). The material is colorized galvanized steel plate, the thickness are 0.5mm, 0.6mm, 0.8mm, 1.0mm.
6). Coud you tell us will you need fixed type conveyor cover or open-close type conveyor cover?

Part open-close type（generally for large belt conveyor width） 

Whole open-close type

What is the Role of Auxiliary Transmission Motor?

Generally speaking, main motor of bucket elevator is used in normal operation,while auxiliary transmission motor is generally used in the repair time.
When the main motor breaks down,starts, or during the repair process, users can use the auxiliary transmission motor to help the main motor start up, ordrive the main motor at low-running speed. The connection structure of auxiliary transmission motor and the main motor is simple,the operation is reliable.

What are the Comparative Edges?
1. When the main motor occurs troublesand cannot operate normally, at first please stop feedingmaterials.In order to protect the bucket traction pieces and hoppers from damage, operators need to clean up the materials which are hung in the air, then operators can start up the auxiliary transmission motor to clean the residual materials inside the hoppercompletely .
2. Compared with main motor, the power of auxiliary transmission motor is much smaller, so with the help of auxiliary transmission, bucket elevator slows down. According to this characteristic, it’s easy to overhaul bucket elevator, clean up hoppers and traction pieces through bucket elevator observation window.

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.

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 ball：good 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.

►IP Grade
IP (INGRESS PROTECTION) grade system is drafted by IEC (INTERNATIONAL ELECTROTECHNICAL COMMISSION ).IP grade is composed of two numbers, the first number represents for anti-invasion grade of external objects and dust, the second the number shows that the sealing degree of anti- invasion of moisture and water, if the number is greater, the degree of protection will be higher.
The first number:
0: no special protection
1: it can prevent external objects with solid diameter larger than 50 mm entering into the casing.
2: it can prevent external objects with solid diameter larger than12 mm entering into the casing.
3: it can prevent external objects with solid diameter larger than 2.5 mm entering into the casing.
4: it can prevent external objects with solid diameter larger than 1 mm entering into the casing.
5: protection against dust, it can prevent dust from entering to affect the normal operation of the product, and prevent dust contacting the inner casing or parts.
6: sealing against dust, it can completely prevent dust from entering into the casing and prevent the dust contacting the inner casing or parts.
The second  number:
0: no special protection
1: drip-proof: vertical drop of water will not directly enter into the motor.
2:15 degrees angle drip proof: within a range of 15 degrees angle, water drop will not directly enter into the motor.
3: 60 degrees angle water spray proof: within a range of 60 degrees angle, water-spray will not directly enter into the motor.
4: water splash proof: splash water in any direction will not bring harmful effects to motor.
5: water spray proof: spray water in any direction will not bring harmful effects to motor.
6: water waves or strong water spray proof: furious waves or strong water spray will not bring harmful effects to motor.
