How to choose between bag dust removal and pulse dust removal?

When choosing the dust removal method for a pulverizer, one often faces two choices: bag dust removal and pulse dust removal. So, how should one choose? We can consider it from several aspects. Firstly, let’s talk about the cost aspect. Bag dust removal is relatively low-cost. Its structure is relatively simple, mainly relying on cloth bags to filter dust. The cost of making and installing cloth bags is not high, and the maintenance cost in the later stage is relatively low, such as the cost of replacing cloth bags, which is not particularly high. So, if your budget is limited and you are sensitive to costs, then bag filter is a good choice. Let’s take another look at their dust removal efficiency. Bag filter is suitable for handling small particle dust. Generally speaking, it can have a good filtering effect for dust with a particle size of ≤ 10 μ m. Because the fiber structure of the cloth bag can effectively intercept these small dust particles. However, when the dust concentration is high or the processing capacity is large, the bag may become clogged, resulting in a decrease in dust removal efficiency. The efficiency of pulse dust removal is relatively high. It uses pulse blowing to clean the dust, which can quickly and effectively remove the dust on the surface of the bag and maintain the breathability of the bag. So, even in the case of large-scale continuous operation, it can maintain a high dust removal efficiency. Moreover, pulse dust removal can automatically clean dust without the need for frequent manual cleaning operations, greatly saving labor and time costs. Another important point is the cleaning method. If the bag filter is manually cleaned, it needs to be cleaned every 2 to 4 hours, which requires manual inspection and cleaning of the bag at regular intervals, which is quite troublesome. Pulse dust removal is an automatic dust cleaning process, which automatically starts the dust cleaning program based on the set pressure difference. Generally, the dust is cleaned every 10 to 30 minutes. This way, there is no need for manual monitoring and the normal operation of the bag can be ensured. Furthermore, from the perspective of applicable scenarios. If your powder mill has a small output, low dust concentration, and strict cost control requirements, then bag dust removal can fully meet your needs. But if your milling machine operates continuously with high output, high dust concentration, and you want to achieve more automated and efficient dust removal, then pulse dust removal will be more suitable for you. So, when choosing between bag dust removal or pulse dust removal, it is necessary to comprehensively consider factors such as cost, dust removal efficiency, cleaning method, and specific production scenarios in order to select the most suitable dust removal method for one’s own pulverizer.
