How to prolong lifespan of belt conveyor

Quality of belt is the main reason to impact on belt conveyor lifespan, so it must purchase the belt with high quality. Meanwhile, it should make sure that sweeper is reliable to use so that there is no material on the return belt. Otherwise, materials adhered to return belt will be taken to the surface of drive pulley and bend pulley, then it will damage belt and reduce its lifespan.
There are some problems in the use of belt conveyors sometimes, to which require you to pay attention that you can greatly extend the service life of belt conveyor.
1. If there is the phenomenon of belt slipping on drive pulley, users should find the reasons and adjust it promptly.
2. Please always check the belt connectors, if there is local damage, please repair it or replace conveyors joints.
3. Please check rollers using conditions regularly. Adding proper lubricating grease into sealing ring when making maintenance. And replace inflexible rotating rollers immediately.
4. It must add good quality lubrication into all rotating parts of belt conveyor. Please add lubrication at fixed period in accordance with the requirements.
5. Please ensure that the cleaning device has good working conditions, and the damaged components should be replaced.
6. Please check tension level of belt conveyor regularly. If the belt is loose, please tension it promptly and observe whether the belt is off tracking, otherwise it should be adjusted timely.

What is the required data for tripper conveyor model selection?

Tripper conveyor can be designed to achieve discharging bulk material along the belt conveyor. It is applied to large area store material in warehouse etc. very well.The tripper conveyor is a kind discharge device, which can achieve multiple point discharging along the belt conveyor system, also can achieve both side discharging or single side discharging.

 

The rail for tripper conveyor is welded on the top of the conveyor intermediate frame, the rail length is designed according to the customer’s required discharging length.

 

In order to send you a better project solution, please supply the following technical requirements: 
1. The required discharge length for tripper conveyor ____m;
2. Do you have any installation space limit;
3. The required capacity ____t/h;

Classification and Characters of Vibrating Screen Spring

Damping spring is common elastic component, it widely used for all kind of vibrating screen, with the features of good stability, lower noise, good vibration isolation effect, long service life etc.

Vibrating screen commonly used spring classifications are steel spring, rubber spring, complex spring etc.

Steel spring: It is made of spring steel, belongs to compression spring, it is the screw spring can bear direction pressure. In general, the cross section of its material is circle, equal pitch, there is a certain gap between the circles. When suffering the external load, the spring will be out of shape and contracted, and store the deformation energy.The screw spring load weight is directly proportional to the wire diameter and circle number.

Rubber spring: It is made of natural rubber, a kind of Polymeric elastomer. With good vibration isolation effect, little resonance area, long service life, low cost and it also with good cold resistance, good gas tightness, waterproofness, it is really a  good choice for vibration damping.

Complex spring: It is an elastomer which combines steel spring and rubber spring together. So it has two kinds of advantage and also overcome their weakness. With a stable shape and mechanical property, it can bear heavy load and big deflection. with the features of vibration isolation, it can  reduce noise. Especially applied for bigger type vibrating screen in mining, metallurgy, coal industry etc.

Joint Methods of Conveyor Belt

The most common joint methods of conveyor belt are mechanical joint, cold bonding joint and heat vulcanization joint. Here PK Machinery will discuss three different joint methods with you.

1.Mechanical joint

This joint method is to use belt fastener to connect belt. The most obvious advantages are convenient and economical. But this method has lower efficiency and it’s very easy to damage and reduce lifespan of conveyor belt. To connect PVC or PVG anti-flaming and anti-static belt, it’s very universal to adopt this kind of method if the conveyor belt grade is less than grade 8.

2. Cold bonding joint

This joint method adopts binding agent to connect belt. It is with higher efficiency compared with mechanical joint. What’s more, it can save investment cost. But in fact, due to the uncontrollable technological conditions and quality of binding agent, this kind of method is not very stable.

3.Heat vulcanization joint

It has been found that this joint method is the most ideal way to connect belt. It can not only   guarantee the joint efficiency and stability, but also can be easy to master and prolong lifespan  of belt. But it also has disadvantages of troublesome technology, high cost, long joint operation time, etc.

Selecting Methods of Belt Conveyor Roller

How to choose the right roller for the belt conveyor, the method are as the follows!
1.The abrasive and corrosive materials
2.The installation of the supporting roller of the equipment working conditions
Abrasive materials, such as clay, granite and black minerals may be on supporting and selection of important influencing factors, selection of wear resistant materials. To transport corrosive materials, such as salt and chemicals and need to choose resistance to corrosive materials of roller. In steel supporting roller coating or is selection of resistance to corrosion of high roller. Harsh environmental conditions especially in dusty conditions (cement, limestone, the ash) roller to have the best sealing system, provide the highest possible protection is necessary.

How much knowledge do you know about belt conveyor magnetic separator ?

When customers purchase belt conveyor, they only provide conveying material name, but seldom mention whether the material contains other impurities or not.For example, if long and big iron contained in the material, it will be easy to scratch the conveyor belt, so magnetic separator plays an important role.In this article,we will introduce the magnetic separator as follows:
Magnetic separator is applicable to various fields deironing, which can realize continuous iron absorption and removal.
Please pay attention to the conveyor belt, bandwidth, dip angle, material properties, moisture, material thickness an iron content percentage, the nature of the magnetic material, as well as the deironing requirements and the environment condition to select a suitable magnetic separator.
Magnetic separator can remove the ferromagnetic impurities which are mixed in material, to ensure the safe and normal transmission system work of the crusher, grinding machine and other mechanical equipment,at the same time it can effectively prevent belt scratch caused by the large, long iron besides,the grade of raw materials can be significantly improved.
