Reasons and solutions of dust in cone crusher

The cone crusher has a good crushing effect, but everyone who has used the crusher knows that this machine often has a lot of dust during the crushing process, which not only damages the ecological environment but also seriously endangers the health of the staff. The dust problem of the cone crusher should be the most concerned thing in the ore processing plant now. Reason analysis of dust in cone crusher
1. The dust of the cone crusher mainly comes from the inlet, outlet and conveying system. After the material is crushed, it is sent to the next process through the conveyor. In this process, a large amount of dust will be generated. The concentration is very high. Under the drive of the airflow, the dust source will spread to the surroundings, causing serious dust pollution.

2. Reasons for dust production at the inlet
The cone crusher is not a fully enclosed device. During the feeding process, it is inevitable that dust overflow will occur, resulting in a relatively high concentration of dust around the inlet.

3. Reasons for dust production at the outlet
The crushed stone needs to enter the conveyor through the discharge port. Due to the drop between the feed port and the discharge port, a part of the stone will flow into the air. At the same time, during the movement of the conveyor, the stone powder will also follow Raise and spread to the surroundings. Measures to reduce crusher dust
1. Set up 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 spray nozzles are provided at the inlet and outlet of the material, the direction of the water spray nozzle should point to the source of dust.
(2) A vacuum cleaner is arranged at the maintenance port behind the movable jaw of the crushing chamber, and the air duct connected with the fan is made into a retractable pipe, thereby facilitating the daily care of the equipment.
(3) A water spray device is arranged on the conveyor belt to reduce the dispersion of dust during the transportation process.

2. Optimize the transformation of the chute tooth plate and other structures.
(1) Appropriately reduce the inclination angle of the chute chute, thereby reducing the potential energy difference of the material height.
(2) Increase the number of teeth of the tooth plate if the other conditions remain unchanged.
(3) Replace the damaged sieve plate in time to avoid the problem of dust increase caused by material blockage
