Clean environment and meeting environmental protection requirements are the themes that the crusher industry should follow. As a common mine crushing equipment, the crusher will inevitably produce dust in the process of use. We need to find the source of dust, so as to reduce the pollution caused by dust to the environment from the root.
1. The influence of moisture and hardness of crushed materials.
Analysis: when the humidity of the crushed material is high, it is easy to paste the bag when entering the bag filter, and the feeder is blocked, resulting in the decline of the ventilation capacity of the bag filter and serious dust.
Solution: before crushing, the more fine powder contained in the material will affect the crushing, because these fine powders are easy to adhere and affect the transportation. Those with a large content of fine powder should be screened in advance.
2. Selection of crushing and screening equipment.
Analysis: the crusher equipment needs to correspond to the physical properties of the material, and the output of different equipment is different.
Solution: adopt one-stage crushing instead of the traditional multi-stage crushing work process, and adopt the screening equipment with large capacity and multi-layer screen in the screening operation.
3. Transportation phase of materials.
Analysis: during the falling process of materials on the belt conveyor, the air flow and materials enter the closed dust removal hood together, and the dusty gas diffuses outside the hood, thus polluting the environment. In the process of material transportation, places with large inclination are often places with serious dust, which need more attention.
Solution: try to use transportation and transmission equipment with good sealing performance.
4. Dust removal and supporting equipment operation.
Analysis: the bag filter and its supporting parts are prone to failure, which not only affects the normal dust removal, but also increases the amount of equipment maintenance.
Solution: equip with a stable and effective dust removal device that can operate continuously, select a filter material with good rigidity, and the surface is treated with film or coating, impregnation, calendering, etc, which is conducive to improving the dust stripping performance.
In order to reduce the dust pollution of the equipment, from the perspective of the whole process. Under the conditions allowed by the crushing technology, the wet crushing and screening process is used as much as possible, which is a relatively feasible method to reduce dust pollution in the crushing and screening plant.
When selecting equipment, users need to select appropriate specifications according to specific requirements. As a highly professional manufacturer, SMMVIK Machinery will provide users with more professional dust treatment guidance.
