In coal, metallurgy, chemical and thermoelectric devices.Ordinary trough belt conveyor is one of the most commonly used equipment in solid material conveying system, its safety and reliability directly affect the whole system.But when the material from the superior conveyor to the subordinate conveyor is easy to produce sprinkling and dusting phenomenon, resulting in serious environmental pollution and cost waste。Even affecting the normal operation of the entire system。Therefore, it is one of the key problems to ensure the reliable operation of the belt conveyor and the whole material transportation system to understand the causes and influencing factors of the sprinkling and dusting problems and take corresponding measures to suppress and solve the problems.

Dust removal methods include;

1.Biological nano-film dust suppression

The biofilm is a double ionospheric membrane with a layer spacing up to nanometer.Can maximize the ductility of water molecules.And has strong charge adsorption.The biological nano-film sprayed on the surface of the material,Can attract and reunite small particles of dust,So that it is aggregated into large granular dust particles,increase their weight and settle.

2.Cloud dust suppression

Through high pressure ion atomization and ultrasonic atomization,can produce 1μm ~ 100μm ultra-fine dry mist.Ultra-fine dry mist particles fine, fully increase the contact area with the dust particles,The water mist particles collide with the dust particles and agglomerate to form agglomerates.Agglomerates are getting bigger and heavier until the final natural settlement, to achieve the purpose of eliminating dust.

3.Wet dust collection

Through the pressure drop to absorb dust attached to the air.In the centrifugal force and water and dust mixed with the dual role of dust.Unique impeller and other key designs can provide higher dust removal efficiency.

4.Spray dust system

Spray dust system can solve the dumper, material field, shed, belt conveyor transfer point, shaker, discharge point of the site dust.Spray dust includes high pressure water mist and dry fog dust.The impact of dry fog dust on the material humidity is very small.Suitable for water-sensitive materials.Or the owner of the material to increase the humidity requirements of relatively high material.

5.Impact bed instead of impact roller

With the skateboard impact bed instead of the impact roller group in the blanking point, with the skateboard support bar instead of the guide groove on both sides of the side of the roller, to avoid the defective roller group.First, high-strength structural support and high elasticity of the rubber support surface can be reliable, effective absorption of impact.Second, the support surface is uniform, not easy to cause the belt deviation.Third, surface contact, no belt sagging, not easy to cause material scattered and folder.

6.Transfer point dust suppression program

When the material falls on the belt machine,will be in the transport of material separation of dust, spread to the surrounding.This condition occurs, especially between the transfer points of the conveyor,the position of shock and shock.With the increasing demand for environmental protection, how to minimize the problem of reducing the dust generated by the belt conveyor has become a more pressing issue.
