How to Avoid Dust Pollution in Ball Milling and Classifying Production Line?

Ball milling and classifying production line is a traditional method for producing ultrafine powders. It has been widely used in ceramics, chemicals, building materials and other fields. However, ball milling and classifying production line will generate a lot of dust during the processing. This will threaten the environment and human health. How to avoid dust pollution has become a focus of attention for experts and enterprises in the industry.

This article will discuss in detail how to avoid dust pollution from the aspects of design scheme, equipment improvement, operating specifications and cleaning measures.

Ⅰ. Design scheme

The best way to avoid dust pollution is to start with the design scheme of the ball milling and classifying production line. In the design scheme, the following factors need to be considered:

1. Isolation measures

A large amount of dust will be generated in the ball milling and classifying production line. So isolation measures need to be taken to isolate the dust from the environment. For example, equipment such as sealing covers or room air showers can be installed on them to prevent dust from scattering.

2. Exhaust design

Exhaust is one of the important means to avoid dust pollution. By reasonably designing the exhaust system, the dust generated in the ball milling and classifying production line can be quickly discharged from the outside of the equipment, while ensuring production efficiency, reducing the impact of dust on the environment and human body.

3. Dust treatment system

The dust generated in the ball milling and classifying production line needs to be effectively treated to avoid pollution to the environment. For example, filters, wet purifiers and other equipment can be used to treat the dust into harmless substances.

Ⅱ. Equipment improvement

In the actual operation of the ball milling and classifying production line, the degree of dust pollution can also be reduced by improving the equipment structure and parameters. Common equipment improvement measures include:

1. Optimize equipment structure

By improving the structure and parameters of equipment such as ball mills and classifiers, the amount and degree of dust generation can be reduced. For example, measures such as adding a sealing cover to the ball mill and reducing the feeding port can effectively control the generation and spread of dust.

2. Equipment cleaning

Regularly cleaning the equipment in the ball milling and classifying production line can effectively reduce the generation and spread of dust. For example, installing a cleaning device inside the ball mill and regularly cleaning the inside of the equipment can keep the equipment clean and tidy and reduce the degree of dust pollution.

Ⅲ. Operating specifications

The operating specifications of the ball milling and classifying production line and the operating skills of employees also have an important impact on dust pollution. Therefore, in actual operation, it is necessary to formulate reasonable operating specifications and provide necessary training and guidance to employees.

1. Wear protective equipment

When operating the ball milling and classifying production line, you need to wear appropriate protective equipment, such as masks, gloves, etc., to avoid dust from causing harm to the human body.

2. Control the feed speed

In the ball milling and classifying production line, controlling the feed speed is one of the important measures to avoid dust pollution. If the feed is too fast, it is easy to cause dust diffusion and overflow. It will affect the environment and human health. Therefore, in actual operation, it’s necessary to reasonably control the feed speed to ensure processing efficiency and reduce dust pollution.

3. Reasonably adjust the air flow speed

In the classifying process, the air flow speed has an important influence on dust pollution. If the air flow speed is too large, it is easy to blow away the fine dust particles. If the air flow speed is too small, it will affect the processing efficiency. Therefore, in actual operation, it is necessary to reasonably adjust the air flow speed to achieve the best classifying effect and reduce dust pollution.

4. Clean the equipment regularly

Regularly cleaning the equipment and the surrounding environment in the ball milling and classifying production line can effectively reduce the degree of dust pollution. For example, measures such as cleaning the inside of the equipment, cleaning the exhaust system, and cleaning the ground can effectively reduce dust diffusion and accumulation.

IV. Cleaning measures

In addition to the above measures, the degree of dust can be further reduced by strengthening cleaning measures. Common cleaning measures include:

1. Floor cleaning

Laying non-slip and easy-to-clean floor materials around the ball milling and classifying production line and cleaning it regularly can effectively reduce the accumulation and spread of dust on the ground.

2. Air purifier

Installing an air purifier around the ball milling and classifying production line can filter and purify dust particles in the air and reduce the degree of dust pollution.

3. Wet cleaning

Using wet cleaning methods such as water spraying and steam around the ball milling and classifying production line can effectively reduce the degree of dust diffusion and flying.

In short, avoiding dust pollution in the ball milling and classifying production line is a complex and important issue. Comprehensive measures need to be taken in terms of design schemes, equipment improvements, operating specifications and cleaning measures to reduce the degree of dust pollution from multiple angles. In addition, in actual operations, it is also necessary to flexibly take various measures according to specific circumstances to achieve the best results and protect the environment and human health.
