Solve The Problem Of Dust In Jaw Crusher

Guide: Jaw crusher is used as ore crushing processing equipment. In the process of crushing, a large amount of dust often appears in the process of breaking, which will not only cause damage to the ecological environment, but also seriously endanger the health of the staff. Therefore, thoroughly Solving the dust problem of the jaw crusher is an urgent problem to be solved in the current ore processing plant. As a well-known crusher manufacturer, SBM has summarized a set of solutions through market research and analysis.

Jaw Crusher

In order to effectively solve the dust problem of the jaw crusher, we need to know in detail the causes of dust generation. Let's take a closer look at the reasons for the dust of the jaw crusher.

1. Analysis of dusting point of crusher

The dust source of the jaw crusher mainly comes from the feed port, the discharge port and the conveying system. After the material to be processed is crushed and crushed by the crusher, it is sent to the next step through the conveyor. In the process, a large amount of dust is generated, and the concentration is very high. Under the driving of the airflow, the dust source is diffused to the surroundings. Causes serious dust pollution.

2. Causes of dust production at the feed inlet

The jaw crusher is not a fully enclosed device. In the feeding process, dust overflow is inevitable, resulting in a relatively high concentration of dust around the feed port.

3. Causes of dust production at the discharge port

The crushed stone needs to enter the conveyor through the discharge port. Because there is a certain gap between the feed port and the discharge port, a part of the stone will flow into the air. At the same time, the stone will also be in the process of the conveyor. It then rises and spreads to the surroundings.

In order to completely solve the dust problem of the jaw crusher, it is necessary not only to optimize and improve the local structure of the equipment, but also to control the dust source with a certain external force to avoid further diffusion of the dust.

1. Install a sealing cover at the source of the dust, and configure the water spray and dust suction device at the same time.

  • (1) Two water spouts are provided at the inlet and outlet, and the direction of the spout must be reasonable, pointing to the source of the dust.
  • (2) A vacuum cleaner is arranged at the inspection port behind the crushing chamber, and the connecting duct between the fan and the fan is made into a flexible pipe, thereby facilitating daily care of the device.
  • (3) The water spray device is arranged in the conveyor belt to reduce the dispersion of dust during the conveying process.

2. Optimize the structure of the tooth plate and other structures of the chute chute.

  1. (1) Appropriately reduce the inclination angle of the chute chute, thereby reducing the material potential energy difference.
  2. (2) Increase the number of teeth of the tooth plate in other cases.
  3. (3) Replace the damaged sieve plate in time to avoid the problem of dust increase 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, the processing plant needs to adopt the advanced green environmentally friendly crusher equipment and process to produce and adopt the performance. Reliable conveying equipment. Shibang Industry actively responded to the call of the State Environmental Protection Agency and worked hard to develop more energy-efficient, green and environmentally-friendly ore processing equipment, which has made great contributions to the green development of mining enterprises.
