How to Correctly Make Maintenance for Belt Conveyors

As we all know, correct and proficient operation is the guarantee for the efficient working of the belt conveyor.

Excluding the impact from the sundries in the material, in order to improve the conveying efficiency, operators should pay attention to the following points:

1. Make fix and appropriate installation of the belt conveyor machine.
2. Check the belt conveyor before operation.

Make sure the protecting device is all ready, the belt tension is adjust to appropriate degree and so on.

3. The belt conveyor should start with non-load and then be fed after its normal operation.
4. If there are several belt conveyors operate in series, then they should be started in order from the discharging port. Do not feed materials until all conveyors are operated normally.
5. The working condition of the belt conveyor machine. The temperature of the conveying material should between 50℃ and -10℃, and materials with acid and alkali should not be conveyed.

Key Factors to Avoid Belt Skid of Movable Belt Conveyor

Movable belt conveyor is a portable continuous conveying equipment, which has the advantage of convenient movement, high efficiency and easy operating. It can convey bulk material, and bagged material is also in its working range.The lift angle and height is allowed to adjust. Belt skid problems may sometimes be meet in the daily operation, PK machinery is an expert in solving this problem, here are two suggestions:

1. Adjust the belt tightness of the conveyor.

The tightness is a key factor to impact the operation of portable belt conveyor. You can tighten the belt through screw tensioning or hydraulic tensioning to solve the belt skid problem. It probably causes permanent deformation to the belt if the tension range is not enough, in this case, we need to cut a piece of belt off and then vulcanize the belt.

2. If large range of tightness is required while using nylon or EP belt, we can also vulcanize the belt to solve belt skip problem and thus reduce damage to the conveying belt.

We PK Machinery is the most professional manufacturer of  Vibrating screen, Bucket elevator, Screw conveyor, Scraper conveyor.Possessing the world’s most advanced technology, we are ready to meet any needs of customer with the goal of being the future global leader of mining machinery industry.

How to Extend the Service Time of Belt Conveyor

One main factor of impacting the belt conveyor service time is the conveyor belt quality. Therefore high quality of conveyor belt is required in purchasing. Another main factor is that the sweeper is highly reliable to make sure no more material adhered to the return belt, in case they are next sent to the surface of the drive pulley and bend pulley, thus bring damage to the belt and shorten its service time:

Due to how to greatly expand the service time of the belt conveyor, Followings are some suggestions:

1. Avoid belt slipping on the drive conveyor pulley. Please find the reason and give prompt adjust if slipping appears.
2. Check the conveyor belt joints frequently. Damaged conveyor belt joints should be repaired or replaced in time.
3. Check the service condition of the belt conveyor roller regularly. Properlubricating grease should be added into the sealing machine in the maintenance, and also inflexible rotating rollers should be replaced immediately.
4. High quality of lubrication should be added into all rotating parts of belt conveyor periodically according to the requirement.
5. Ensure the good work condition of the cleaning device and replace damaged parts in time.
6. Regularly check the conveyor belt tensity. Prompt tension is needed if the belt is loose. Meanwhile please notice the belt position, timely adjust should be made when it’s off tracking.

The application of conveyor belt fluid coupling

Fluid coupling is a used fluid transmission component. Motor drives coupling pump wheel rotation, pump impeller blade agitates intracavitary working liquid, under the centrifugal effect,pump wheel turns mechanical energy into liquid energy, then passes to the turbine blades, turbine passes the absorbent liquid energy to the machine.
Fluid coupling has the function of flexible transmission,slow down the impact and the isolation of torsional vibration, prolong the start-up time, reduce the starting current,make the motor light load start-up, solve the problem of heavy large inertia load start-up difficulties and protect the motor when overloads, energy and power saving effects are remarkable.
On the conveyor, fluid coupling has the function of connecting motor and reducer ,it replaces the mechanical coupling. The belt conveyor fluid coupling has two effects:
1.Overload protection
If the belt conveyor is overload, fluid coupling slip frequency increases, working fluid warms up, fluid coupling will spray without burning motor to a certain temperature. Of course sometimes coupling will be installed with a temperature control device, when work liquid superheats, temperature control device can control the motor and cut the power cut to protect the motor.
2. Flexible-start
When motor starts,belt conveyor starts slowly and acceleratedly , this can reduce the grid big impact to make the motor start up in light load. At the same time,it can reduce the effect of belt tension,protect belt and prolong life, especially under the heavy load start-up.

Do you know difference of TD75, DTII and DTIIA series belt conveyor?

Specifications of TD75, DTIIA, DTII series belt conveyors are the national standard of China belt machine, which represent three types of conveyors.During the model selection,the standard should be noticed. How to choose a proper type to save client’s cost? The following is the characteristics of the three types of conveyors:
TD75 series conveyor is the first standard belt conveyor, it can be used to convey small lump, granular, powder material, due to simple structure, low cost, easy maintenance, convenient maintenance, and large transport capacity,TD75 series belt conveyor becomes a common machine,it can be single or multi sets running to form a horizontal or inclined conveyor system.
DTII series belt conveyor is designed according to the components. The designers can design and assemble the conveyor according to the requirements of transportation, different terrain and working conditions,it has a wider use compared with TD75 type.
DTIIA series belt conveyor a heavy duty machine is mainly used to transport large density, large transport capacity and long transmission distance, conveyor selection is determined according to many parameters.

Daily, Weekly, Monthly Belt Conveyor Check&Maintenance Work

When using the belt conveyor, less daily check and maintenance or do not pay attention to maintenance will greatly reduce the service life of the belt conveyor, when the belt conveyor problems occur, it will affect the work efficiency, so regular inspection for belt conveyor parts is needed.
Daily check
Mechanical items: inspect the guardrail, bridge, roller, pulley, turnabout pulley and belt.
Electrical items: inspect the anti-skid device, deviation switch, emergency stop switch, tear detection device, anti-reverse device.

Weekly check
Mechanical items: inspect the driving wheel, guide wheel section, reducer, inspect the machine's tail, check tensioning device and pull rope device.
Electrical items: inspect the main motor, inverter, filter, repair and inspect the main transformer wiring, electrical control, power system.
Monthly check
Mechanical items: inspect the rope wheel, transition wheel, guide wheel, driving wheel, belt wheel, tensioning car and check the oiling.
Electrical items: inspect the fastening bolts, fast switch; the maintenance and repair of commutator, limit protection, emergency stop protection and the alarm system.
