The crushing and screening system of limestone quarry is optimized and upgraded in the dust removal system
Limestone is a very common raw material. Now the popularity of artificial sand and gravel is unabated, and it is a good time to do great things. However, many quarries have closed down at present, because the environmental audit is difficult to pass. The crushing and screening system of the limestone quarry can easily pass the environmental audit after the dust removal system is optimized and upgraded.
Limestone quarries: the main polluting force of dust and noise
A large amount of dust will be generated during the crushing and screening of limestone, which not only harms human health, but also pollutes the atmospheric environment. Therefore, it is necessary to dedust the crushing and screening workshop.
Design scheme of dust removal system for crushing and screening workshop in limestone quarry
According to local conditions, in order to achieve environmentally friendly production, firstly plan a suitable dust removal scheme according to the actual situation such as the geographical location of the workshop, and carry out dust removal and noise reduction design according to the scheme, including the selection of the sealing method of dust removal equipment and the selection of dust removal system equipment. Practice has proved that the design scheme is very reasonable.
The crushing chamber of the crusher is a closed structure during operation, so the dust sources of the production line are mainly the discharge port, the chute and the vibrating screen.
Due to the drop between the inlet and outlet, the flow of stone powder will shear with the surrounding air. The air is sucked into the material flow, the stone powder flow gradually spreads, and the mutual suction force makes the dust fly out continuously; at the same time, the belt of the conveyor has a moving speed, and the impact of the stone powder flow and the surface of the belt instantly raises the dust at the discharge port, everywhere flying will produce a lot of dust;
Similarly, in the process of stone classification, the airflow on the screen surface is in a stable state, and some fine dust in the stone is raised under the vibration of the screen. After the dust is generated at the dust source, it is driven by the airflow in the environment to spread around, forming dust pollution.
The main reasons for dust pollution are clarified, and the next steps to be taken are also clarified, that is, the dust generating site should be sealed, that is, the dust generating point should be sealed with a sealing cover, so that the dust can spread in a small area as much as possible.
In addition, in our buildings, users choose to move the production line indoors to form an indoor crushing and screening production line, so as to deeply optimize dust pollution, isolate noise, and achieve environmentally friendly production.
