Causes and treatment methods for scratches on the belt of the iron remover

Many countries attach great importance to the recycling of construction waste, and have proposed many incentive policies to allow everyone to use construction waste to produce machine-made sand. We all know that construction waste contains a lot of metal objects such as steel bars and nails, so an iron remover is needed to remove iron. However, the iron remover belt is indeed easy to be scratched. To sum up, the reasons are as follows.

1. The quality of the belt is not good

There are always people who don't believe in the truth of "you get what you get for every penny" and want to make do with it. Can the two-layer support frame and the 8-layer support frame, high-strength wear-resistant rubber and belts made of general rubber be the same? The frequency of belt scratches is too high, should I consider changing the belt manufacturer?

2. The iron remover hangs too low

The hanging height of the iron remover is designed by the manufacturer according to the customer's production requirements, just in line with the material flow. However, there will always be deviations in actual production. When the material flow is greater than the design flow, the suspension height of the iron remover is not enough to avoid the material thrown from the head of the belt conveyor, and the thrown material will impact the belt, causing the belt to be caught in the material. scratches by sharp objects.

3. The iron remover belt goes too slowly

Under normal circumstances, the speed of the Conveyor Belt should be the same as the speed of the belt of the iron remover. When the belt of the iron remover is running at a slow speed, when the sucked material is attracted to the belt by the magnetic force, it will give the belt a hard impact. It is easy to cause damage to the belt.

4. There are many iron parts

There is no need to say this to Boss Wan, who handles construction waste. After all, his raw materials determine that there are many large and long iron pieces inside, which are more likely to scratch the belt than ordinary materials. However, bosses who deal with other materials can refer to it and try to avoid large and long iron parts in the materials.

Iron remover belt repair method

1. Leave a patching area

Find the scratched rip in the belt and cut a repair area within 4cm of each side, about 3mm deep. The belt is relatively strong, so you need to have a peeler on hand.

2. Paint and repair glue

In this step, you have to do it while peeling, and apply a layer of primer to the repair area after every 5 cm of peeling. After 15 minutes, the primer is slightly dry, then apply the mixed repair glue to the repair area and smooth it. The amount of glue is 3.5 meters for a group, and a group is about 400 grams.

3. Heat setting

In order to speed up the repair time, you can put a heating blanket on the belt in winter to heat the surface. Of course, it is not necessary to have a temperature above 15°. After smoothing the repairing glue, stick the repairing glue on it, and use a Special Roller to press the repairing skin evenly to make it stick more firmly.

4. Pressure to close

Basically the belt has been repaired, in order to make the repaired area stronger and glued more firmly, put a heavy weight on the repaired area and leave the rest to time.

Although the belt of the iron remover is a wearing part, frequent damage will also affect our work progress. Therefore, we must strictly control the quality from the beginning. The feeding amount and conveying speed must meet the design requirements of the iron remover. Try to repair it first to prolong the service life, and then replace it after the belt is used up.
