Description

Technical Field

[0001] The utility model belongs to the technical field of crushers, in particular to an anthracite crusher. Background Art

[0002] In the existing crusher technology field, especially in the crushing process of anthracite, the smoke problem has become an important factor restricting production efficiency and the quality of the working environment. In the crushing process of traditional anthracite crushers, due to the high-speed collision and friction of materials, a large amount of smoke will inevitably be generated. More seriously, the feed port of the crusher is prone to airflow disturbance during high-speed rotation or vibration. This airflow disturbance causes the smoke generated during the crushing process to be driven by the strong airflow, flow back from the feed port, and directly dissipate into the air. The refluxed smoke spreads rapidly with the flow of air and diffuses into the entire working environment, which not only increases the smoke concentration in the air and reduces the air quality, but also poses a serious threat to the respiratory system of the operator. Working in such a high smoke concentration environment for a long time will not only have a serious impact on the health of the operator, such as causing occupational diseases such as pneumoconiosis, but may also lead to safety hazards such as dust accumulation of equipment and electrical short circuit at the work site, thereby threatening the safe and stable operation of the entire production line.
