How to completely solve the jaw crusher dust problem

Jaw crusher as the first choice for ore crushing and processing equipment, in the process of crushing often there will be a lot of dust, spread to the air, not only will damage the ecological environment, but also seriously endanger the health of the staff, so thoroughly Solve the jaw crusher dust problem is the current ore processing plant in urgent need to solve the problem. Joyal machinery as a professional manufacturer of crusher, after market research and analysis, summed up a set of solutions.

Analysis of Dust in Jaw Crusher

To effectively solve the jaw crusher dust problem, we must produce a detailed understanding of the causes of dust, the following we have to look at the specific cause of jaw crusher dust and more reasons.

1, Crusher dust analysis

Jaw crusher dust source mainly from the feed port, outlet and conveyor system. The material to be processed by crusher crushing, broken, the conveyor sent to the next step in the process will produce a lot of dust, the concentration is very high, driven by the air, the dust source will spread to the surrounding, Causing serious dust pollution.

2, the source of dust production reasons

Jaw crusher is not a fully enclosed device, in the feeding process, inevitably produce dust spill phenomenon, making the feed around the mouth to produce a relatively high concentration of dust.

3, the outlet mouth dust reasons

After the broken stone need to go through the discharge port into the conveyor, due to the feed port and the discharge port between a certain gap, there will be part of the stone into the air, while the conveyor in the course of the movement, the stone powder will Then raised, spread to the surrounding.

Second, reduce jaw crusher dust measures

To solve the jaw crusher dust problem, not only need to optimize the local structure of the equipment to improve, but also with a certain amount of external control dust sources, to avoid further diffusion of dust.

1, in the dust source at the set of sealed cover, while the configuration of water and dust collection device.

(1) in the inlet and outlet at the set of two water nozzles, the direction of the nozzle must be reasonable, pointing to the source of dust.

(2) in the crushing chamber moving jaw behind the mouth of the configuration of the vacuum cleaner, with the fan between the connection duct into a scalable pipe, so as to facilitate the daily care equipment.

(3) in the conveyor belt part of the configuration of the water spray device to reduce the dispersion of dust during transport.

2, the chute chute of the tooth plate and other structures to optimize the transformation.

(1) appropriate to reduce the chute chute tilt angle, thereby reducing the material potential potential difference.

(2) increase the number of tooth teeth in the case of other circumstances unchanged.

(3) in time to replace the damaged sieve, so as to avoid the dust caused by material congestion caused by the problem.

The above measures can greatly reduce the jelly crusher dust emissions, for large-scale processing plants, in order to completely solve the dust problem, but also the need for processing plants as far as possible the use of advanced green crusher equipment and technology for production and performance Reliable delivery equipment. Joyal machinery to actively respond to the call of the State Environmental Protection Agency, efforts to develop a more energy efficient, green, environmentally friendly ore processing equipment for the mining enterprises to make a great contribution to the green development.
