Jaw crusher is the first choice of ore crushing processing equipment. During the crushing process, a large amount of dust often appears and diffuses into the air, which will not only cause damage to the ecological environment, but also seriously endanger the health of the staff. Therefore, a thorough Solving the problem of jaw crusher dust is an urgent problem to be solved in current ore processing plants. As a well-known crusher manufacturer, Bellian Machinery has summarized a set of solutions after market research and analysis.

1. Analysis of the causes of jaw crusher dust
In order to effectively solve the dust problem of jaw crushers, we must have a detailed understanding of the causes of dust generation. Let's take a look at the reasons for the excessive dust in jaw crushers.
1. Analysis of the dust production point of the crusher
The dust production source of the jaw crusher mainly comes from the inlet, outlet and conveying system. After the materials to be processed are squeezed and crushed by the crusher, they are sent to the next process by the conveyor. During this process, a large amount of dust will be generated with a very high concentration. Driven by the airflow, the dust source will spread to the surroundings. Cause serious dust pollution.
2. Reasons for dust production at the feed port
The jaw crusher is not a fully enclosed device. During the feeding process, dust overflow will inevitably occur, resulting in a relatively high concentration of dust around the feeding port.
3. Causes of dust production at the discharge port
The crushed stone needs to enter the conveyor through the discharge port. Due to the certain drop between the feed port and the discharge port, some of the stone will flow into the air. At the same time, the stone powder will also Then it rises and spreads around.
2. Measures to reduce dust in jaw crusher
In order to completely solve the dust problem of jaw crushers, it is not only necessary to optimize and improve the local structure of the equipment, but also to control the source of dust with the help of certain external forces to avoid further spread of dust.
1. Set up a sealing cover at the source of dust, and configure water spray and dust collection devices at the same time.
(1) Set two water nozzles at the inlet and outlet respectively, and the direction of the water nozzles must be reasonable and point to the source of dust.
(2) A vacuum cleaner is installed at the inspection port behind the movable jaw of the crushing chamber, and the connecting air duct between the fan and the fan should be formed into a scalable duct, so as to facilitate the daily maintenance of the equipment.
(3) Water spraying devices are installed on the conveyor belt to reduce the dispersion of dust during the conveying process.
2. Optimize and transform the tooth plate and other structures of the chute.
(1) Appropriately reduce the inclination angle of the chute to reduce the potential energy difference of the material height.
(2) When other conditions remain unchanged, increase the number of tooth plates.
(3) Replace the damaged sieve plate in time to avoid the problem of increased dust caused by material blockage.
The above measures can greatly reduce the dust emission of the jaw crusher. For large-scale processing plants, in order to completely solve the dust problem, it is necessary for the processing plant to adopt advanced green and environmentally friendly crusher equipment and processes for production, and adopt performance Reliable conveying equipment. Bellian Machinery actively responds to the call of the National Environmental Protection Agency, and strives to develop more energy-saving, green and environmentally friendly ore processing equipment, making great contributions to the green development of mining enterprises.
