As equipment for ore mining, the working environment faced by jaw crushers is often harsh. Large pieces of ore will inevitably generate a lot of dust during the crushing process. To solve the problem of dust pollution, one is to use external forces to control the source of dust. Its proliferation, the second is to improve the local structure of the machine, the specific measures are as follows: 1. Two water spray nozzles can be set at each of the three main parts of the inlet, the outlet and the movable jaw crushing cavity. The two nozzles at the inlet point to the inlet; the two nozzles at the outlet are formed oppositely The angle makes the sprayed mist form a cross state to achieve the spray effect; the nozzle at the crushing cavity is set behind the movable jaw and is at an angle to the horizontal.
2. A vacuum cleaner can be installed at the discharge port and the inspection port behind the movable jaw of the crushing chamber. The dust hood of the discharge port vacuum cleaner is about 1000mm away from the discharge port, and the plane of the dust hood is perpendicular to the direction of dust flow; The connecting duct between the suction hood of the rear-jaw cleaner and the fan is designed as a flexible duct to facilitate the refueling and daily maintenance of the broken mobile jaw.
