The vertical grinding machine generates dust flying during the production process, which not only pollutes the environment but also causes material waste. Therefore, the dust removal equipment equipped in the production process of the vertical grinding machine is an urgent problem. Our company is engaged in the research and production of dust collectors for mining machinery and has considerable experience in dust control. At present, the dust removal system of vertical mills mainly uses bag filters as the main equipment, and some vertical mill dust collection systems use cyclone dust collectors for product collection according to actual production needs. This production process layout can reduce the negative pressure of the system and the airflow through the dust collector. The grinding gas directly enters the bag filter, which can reduce the number of equipment and simplify the system configuration. The vertical mill dust removal system can use electrostatic precipitators or bag filters as the final dust removal equipment.

The pulse bag filter for vertical mills is specially developed by our company based on the fine and dry characteristics of vertical mill dust. This type of dust collector is a dry dust removal equipment used to capture small and dry non fibrous dust and recycle it. It adopts a pulse jet cleaning method, which has the characteristics of good results, purification, long service life of dust removal filter bags, low maintenance workload, and operation. In addition to being widely used in various types of vertical grinding machine dust removal systems, it is also a dust removal equipment for dispersing dust points such as the top and bottom of the machine, which can be widely used for purifying dust from various crushing and screening equipment.

　　

The inlet of the dust collector is connected to the outlet of the vertical grinder, and the dust containing gas enters the ash hopper through the side inlet of the box. When the airflow hits the guide plate and turns to the dust bag chamber, the coarser particles directly fall to the bottom of the ash hopper, and the fine dust rises with the airflow. When the airflow passes through the filter bag, the dust is trapped on the surface of the filter bag. The purified gas is collected in the clean air box through each dust removal bag, and then enters the clean air exhaust channel through the butterfly valves of each outlet for discharge.

　　

The online pulse blowing technology has the advantages of dust cleaning and low operating resistance. The dust removal efficiency of the dust collector accessories. Automatic control, easy maintenance, high operating efficiency.

Some issues to consider when selecting an electrostatic precipitator for a grinding machine: For some grinding machines, excessively high inlet temperatures can easily cause damage to the equipment. To solve this problem, the process system is usually designed with valves that mix cold air into the flue gas entering the mill. Although this reduces the temperature entering the mill, it causes an increase in flue gas volume and a decrease in humidity, resulting in poor dust collection efficiency of the electrostatic precipitator. So a better approach is to spray water at the inlet for cooling.
