Environmental Protection Considerations for Crusher Equipment Operation

Heavy hammer crushing production generates large amounts of ash and dust, causing severe environmental pollution and prompting reflection on environmental protection. Baghouse dust collectors and their supporting components are prone to frequent failures, which not only affect normal dust removal but also increase equipment maintenance workload.

We need rapid economic development, and we also need clear waters and green mountains. How to achieve harmonious development between modern industrial growth and the environment is a key theme of our time. Mechanization has opened up more possibilities for the modern economy, but the operation of such machinery—for example, in heavy hammer crushing production—generates large volumes of ash and dust, leading to serious environmental pollution and sparking discussions on environmental protection. How to control dust pollution has become a critical consideration for many crusher equipment manufacturers. Below is a brief introduction to situations where crushers produce excessive dust:

1. When the moisture content of crushed materials is high, the baghouse dust collector is prone to bag clogging, and the discharger is easily blocked, resulting in reduced ventilation capacity of the baghouse and severe dust emissions.

2. The baghouse dust collector used in hammer crushers has a relatively small filtration area and insufficient air extraction volume, making it difficult to form a slight negative pressure in the dust hood at the discharge port and the crushing chamber, leading to high dust levels.

3. Frequent failures of baghouse dust collectors and their supporting components not only disrupt normal dust removal but also increase the workload of equipment maintenance.

4. During the falling of materials on the belt conveyor, airflow enters the enclosed dust hood together with the materials, causing dust-laden gas to diffuse outside the hood and pollute the environment.

5. In actual production, water is often sprayed at the crusher inlet when materials are dry, which worsens bag clogging and discharger blockage in the baghouse dust collector. Since baghouse dust collectors perform ash cleaning intermittently, attention must be paid to air leakage from the lattice wheel to reduce dust emissions caused by air leakage from the heavy hammer crusher shell.
