Great Changes in Technology of Conveyor Belt

With the development of scale of mine, belt conveyor has kept on towards large scale and presents features of large capacity and long distance. Belt conveyor with long distance and multi power has achieve successful research and development, it changes the single load-carrying way that is given by rollers and adopts multipoint electric drive. This method can address the traditional problems that are changing conveyor belts frequently and belt breakdown easily. Also, the successful development of this kind of belt conveyor can reduce the cost of equipment greatly. What’s more, its advantages are reducing thenumber of transshipment or fall of ore during operation and avoiding environmental pollution.

 

The successful development of belt conveyor with 1km-100km belt length, adopting multipoint electric drive which can reduce 10%-30% investment and operation cost. Especially, it can decrease belt strength and eliminate risk of tapebreak of upward transport belt conveyor with large angle and long distance. And then it can prolong the lifespan of belt more than 5 times. Multi-power belt conveyor not only can achieve the goal of lower investment, lower consumption and resistance, but also operate stably more than 10 years. In this way can it improve the running rate and economic benefit greatly.

The Application of Vibrating Screen in Ceramic Industry

Vibrating screen is widely used in abrasive, ceramic building materials, foundry industry, food, paper making, metallurgy, pharmaceutical, environmental industries, however, concerning the ceramic industry, how much do we know ?

 

Exquisite porcelain calcining technology is very strict to the requirement of raw materials, in the screening process of ceramic materials, generally, the particles are required to be sieved in a high precision, due to the choice of the vibrating screen should contain a variety of elements such as: granular distribution, density, water content, viscosity, temperature and capacity, etc., you can select different vibrating screen as per different raw ceramic materials as follows:
1. rotary vibrating screen is suitable for the requirement of high precision material and small production output.

 

2. ultrasonic vibrating screen is suitable for the requirement of high screening efficiency.

 

3. linear vibrating screen is suitable for the requirement of large output and precision is not as good as rotary vibrating sieve.

How the Conveyor Pulley used in the Belt Conveyor

► Brief introductionConveyor pulley is a mechanical device which stays at two ends of belt machine, guides the belt running, and changes the belt direction and tensions the belt. 

Types: driving pulley; bend pulley; coating pulley (includes vulcanized pulleys and cold adhesive pulleys). 

The type of rubber surface could be flat, herringbone and rhombic.

► Features
1) Steady running
2) Less noise
2) Less movement longitudinally
3) Various bearing housing
4) Multistage labyrinthine sealing;
5) High load, low shaking 

► Application
The belt conveyor drum usually installs in the belt conveyor which is used in coal mines, metallurgy, machinery, ports, construction, electricity, chemistry, food packing and other industries

The Reason Why Circular Vibrating Screen can not Start up or Amplitude is Small

Circular Vibrating Screen is a kind of new and highly effective vibrating screen that does circular vibrations and has multiple layers which is available for smelting , quarry , coal preparation, ore dressing, energy, power, chemical industry, construction material. Here PK Machinery will introduce the problem we may meet during the operation of circular vibrating screen.

The reason why circular vibrating screen can not start up or amplitude is small

1. Low voltage
2. The control circuit of electrical components damage
3. The motor damages
4. The motor occurs failure
5. Too much materials are piled up on screen surface
6. Grease caking inside the motor 

The solution to slove circular vibrating screen can not start up or amplitude is small

1. Change the power supply
2. Replace the electrical components
3. Replace the motor
4. Maintain the motor
5. Clean up the materials on screen surface
6. Clean the motor, add proper grease
 

Silicon Carbide Rotary Vibrating Screen Site Operation Feedback from Iran Client

We were delighted to receive the feedback from Iran Client concerning the site operation of rotary vibrating screen which was ordered in the year of 2014.

The rotary vibrating screen was designed for 3~5t/h capacity of silicon carbide, the density is 2-3.2 g/cm3,water content:2~5%,material size:<1mm,as per the screening material, our engineer selected 3 units of XZ1200 rotary vibrating screen with 3 layers to meet the requirement, the material of screen mesh is SUS304,mesh size of 1st: 0.106mm, 0.075mm, 0.063mm;mesh size of 2nd unit: 0.18mm,0.15mm, 0.125mm;mesh size of 3rd unit: 0.3mm,0.25mm, 0.212mm.

 

Iran client said that they were quite pleased with the machine, both the screening efficiency and screening accuracy were higher than the vibrating screen they ever used. At the same time, we also received a site photo after the screens were installed from client, they said after being put into use, screens ran quite well as they strictly operated according to the operation manual, furthermore, they expressed that they would like to order some spare parts, such as screen frame, screen mesh ,sealing ring and bouncing ball etc. Both of us hope to cooperate again in the near future.

The Introduction of Ultra High Molecular Polyethylene Roller

► Brief introduction
Ultra high molecular polyethylene roller is an advanced product which is to substitute stainless roller, which has some disadvantages such as heavy, easy to be eroded, easy to stick with transporting material, high static electricity and others. it includes ultrahigh molecular polyethylene pipe which produced by high technology as its body, bearing seat and seal are fully rubber material made by one-time. Then, they are sealed with three layer of water-proof and dust-proof installation via labyrinth and contact method
► Features
1. Good Lubricity and not bonding, so no bonding and piling up material on the surface of the idler. Guarantee the steady operation of the belt conveyor.
2. Friction coefficient is much lower than steel, reduce the friction between the idler and belt, that reduces the driving force of the belt conveyor.
3. Long working life, is 3~5 times of the steel.
4. Because of the good performance of the UHMW-PE, also extending the working life of the belt conveyor.
5. Light weight which is 1/3~1/2 of the steel weight, conveniently installing and changing, reducing the maintance and labor intensity and also reducing the 25% electricity.
6. Effectively reducing the operation noise, UHMW-PE has better shock absorbing performance and damping performance.
7. Good load bearing performance and anti-corrosive performance, it can be meet the heavy load of the belt conveyor according to the adjusting the thickness 8. Adapt to large scope of the working temperature. ( can work from -40℃ ~ 80℃) 
►ApplicationUltra High Molecular Roller is the substitution product of stainless roller; it is also equipped in the belt conveyor, which is widely used in coal mines, metallurgy, ports, construction site, power station, and chemical, especially in food and medicine industries.

Repeat Order- Frame of Gyratory Screen was Delivered to Indonesia
