How to reduce the impact of materials on belt conveyor?

Material pair Belt conveyor The impact often occurs at the receiving part of the belt. The impact will damage the covering rubber on the belt, fatigue fracture of the belt core, bending deformation of the funnel and frame, and seriously affect the service life of the belt and belt conveyor. Therefore, it is very important to choose different buffer devices and methods in design. The following introduces several ways to slow down the impact of materials on the belt conveyor.


1. Reduce the drop height of blanking point

For the fixed conveyor, the drop height of the loading point should be reduced as much as possible in the overall design, so as to obtain smaller blanking kinetic energy. In the temporary storage yard and construction site, the head and tail phase belt conveyor is often used to form a series operation mode, which not only reduces the kinetic energy of materials, but also avoids the material falling outside the next belt conveyor.

2. Cushion idler is used

It is a common method to set buffer idler in the receiving section of conveyor belt, which is simple and effective for materials with small impact force.

3. Buffer bed is used

The buffer bed is used to buffer the material dropping point, which can effectively avoid and alleviate the tearing of the belt caused by sharp objects, prevent the belt from running off, and reduce the damage of the belt caused by material impact to a certain extent. Reasonable structure of longitudinal buffer strip and anti overflow rubber lining plate can solve the sealing problem of guide groove.

4. Set different buffers and guide grooves

For example, setting up multi-stage buffer chute, multi section slope chute, grid type material receiving buffer, curtain type buffer feeder, setting up material accumulation area to form buffer feeder, so that the direction of material inflow is consistent with the direction of conveyor belt, etc.

5. Select the appropriate feeding device

It is one of the most widely used buffering methods to select the suitable feeding device to withstand the impact of material flow. For example, belt feeding is suitable for most small particle size materials, crawler feeding is suitable for ore with large impact force and large particle size, and vibrating (reciprocating) feeding device is usually used under the requirements of quantitative feeding.

6. Comprehensive anti scour measures

When using, it can not use a single item, but according to the actual situation and environmental conditions, combined application. For example, if the conditions limit that the receiving area should not occupy a large space, but the impact kinetic energy of the material flow is quite high, in order to reduce the impact, the rubber buffer roller is installed in the material receiving section of the conveyor belt, and then the roller support is placed on the cushion rubber pad, One end of the buffer beam is fixed on the other end of the buffer beam to form a spring bearing layer.

In a word, there are many kinds of buffer devices for belt conveyor, but which way to choose should be based on the characteristics of the working conditions, that is, the material granularity, the working site, the load condition of the loading place, etc.
