The reasons for the high dust content of jaw crushers are as follows:

1. Analysis of dust-generating points of crushers

The dust-generating links of jaw crushers are mainly concentrated in three parts: feed port, discharge port and material conveying system. When the raw materials enter the crusher, they are strongly squeezed and crushed to form fine particles. These particles are then transported to subsequent processes by conveyors. In this process, a large amount of dust is released due to the violent crushing of the materials, and the dust concentration is extremely high. Driven by air flow, dust will quickly spread from the dust source to the surroundings, causing the dust pollution problem in the surrounding environment to be extremely serious.

2. Reasons for dust generation at the feed port

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

3. Causes of dust generation at the discharge port

The crushed stone needs to enter the conveyor through the discharge port. Due to the certain height difference between the feed port and the discharge port, some of the stone will flow into the air. At the same time, during the movement of the conveyor, the stone powder will also be raised and spread to the surroundings.
