What is the reason for the excessive dust collector material of Raymond mill?

Raymond Mill. Causes of too much material in the dust collector.

1. The counterweight of the lower pressure valve of the powder collector is too heavy, which cannot be lifted naturally, and the material cannot come out, and the material will be brought back to the fan or dust collector when it is stored too much;

Second, after the dust collector has been used for a period of time, it is not cleaned in time, as the dust accumulates on the surface of the dust collector, some fine particles that have been attached to the filter cloth will be squeezed over, so that the efficiency of the dust collector will decrease, and the materials will accumulate more and more.

The solution to the excessive material of the Raymond mill dust collector.

1. The powder collector can not store too much material, the distribution of the pressure valve should be lifted up when there is material, which can ensure uniform discharge, and the pressure valve should be pressed down when there is no material in the powder collector. For the sake of convenience, some users simply directly match the weight, and the lower pressure valve has been pressed, which will cause the mill to not produce the material, and bring back the materials in the powder collector, so when using the equipment, customers and friends must operate in the correct way.

2. The dust collector must pay attention to timely cleaning, and the daily cleaning methods: 1. Use high-pressure gas or external atmosphere to blow back the filter bag to remove the accumulated dust on the bag; 2. Through the mechanical vibration, the dust attached to the cloth bag falls, and the mechanical vibration device is used to take turns to shake in turn, and the dust is removed by this method; 3. You can also use manpower to pat the filter bag to remove the dust; 4. According to the material provided by the manufacturer, purchase and produce by yourself, if the dust removal effect is not good, or if you find that there is a phenomenon of cloth bag bonding, remove this cloth bag and replace it with a new one, and then do not throw away the old cloth bag, use water to clean and dry it to be used again.

After the filter material of the dust collector is used for a period of time, due to the effects of screening, collision, retention, diffusion, static electricity, etc., a layer of dust accumulates on the surface of the filter bag, which is called the primary layer, and in the subsequent movement process, the primary layer becomes the main filtration of the filter material.

layer, relying on the effect of the primary layer, the filter material with large mesh can also obtain high filtration efficiency. As dust accumulates on the surface of the filter media, the efficiency and resistance of the dust collector increase accordingly, and when the pressure difference between the two sides of the filter media is large, it will.

Some of the fine dust particles that have been attached to the filter media are squeezed over, which reduces the efficiency of the dust collector. In addition, too high resistance of the dust collector will significantly reduce the air volume of the dust collection system. Therefore, after the resistance of the dust collector reaches a certain value, it is necessary to:

Timely ash removal. The initial layer can not be destroyed during ash cleaning, so as not to reduce the efficiency.

We must pay attention to the accumulation of dust on the surface of the filter bag, and the methods of removing the dust are: using high-pressure gas or external atmosphere to blow back the filter bag to remove the dust on the filter bag. It can also be shaken off by mechanical vibration, so that the dust attached to the filter bag is shaken off, and the mechanical vibration device is used to periodically shock the building, and this method removes the accumulated dust.

We can also use manual pat of the filter bag to remove the accumulated dust.

According to the above reasons, it may be caused by the friend's dust collector not cleaning regularly. Hope, thank you.

1. First of all, check whether the two dampers of the Raymond machine are closed. Raymond mill adopts circulating air design, under normal circumstances, the mill should be the inlet of the inlet to the inward exhaust, the outlet to the outward air, the air volume is closed to circulate in, and the inlet is sprayed with powder.

2. The cloth bag on the dust box must be kept breathable and patted once a day. The main function of this cloth bag is to remove dust, cool down and exhaust.

3. Check the link pipeline of the mill to see if there is any air leakage. The air leakage on the pipe is to suck air inside, and it must be carefully inspected if it is not outside the air.

Mingxin. Heavy industry.

Raymond Mill. New crushing equipment for the energy industry. Raymond mill is the most common in the heavy industry industry.

Milling equipment. The dust generated by Raymond mill in use includes dust, dust, soot, etc

Mineral dust. and other forms of envy. At.

Raymond mill.

In the process of use, there are four reasons for the formation of dust.

1. Castings used in Raymond mill equipment.

Foundry. In the process of mixing, screening, packaging, handling and other operations of sand cleaning powdery substances, as well as the deposited dust due to vibration or air flow movement, the deposited dust floats in the air again (producing secondary dust) is also dust.

2. Machining or crushing of Raymond mill equipment, such as metal grinding, cutting, drilling, blasting, crushing, grinding, processing of agricultural and forestry products, etc.

3. Organic matter.

Particulate formed by incomplete combustion, such as soot generated by the combustion of wood, oil, coal, etc.

4. Dust particles formed by the condensation of vapor produced when the substance is heated in the air or oxidized, such as metal smelting, welding, casting, etc.

and other technical measures to optimize and combine, and adopt comprehensive management. Raymond mill equipment is the star recommended product of Mingxin Heavy Industry Heavy Industry Machinery ****, no matter from the quality, after-sales is a trustworthy manufacturer, Raymond mill equipment through the design of Mingxin Heavy Industries Raymond mill engineer and stand on it.

A new beginning. Height.

Mingxin Heavy Industry has recently developed a new type.

High-pressure Raymond mill.

The new Raymond mill adds vacuuming.

Purification equipment. According to the nature, concentration, dispersion and amount of dust, the appropriate dust removal and purification equipment are used to eliminate and.

Purify the air. and prevent secondary dust. Ventilation and dust extraction of the new Raymond mill:

Ventilation and dust exhaust are divided into comprehensive mechanical ventilation and local mechanical ventilation according to the working place and environmental conditions. Ventilation is to bring clean fresh air to the workplace continuously, and the air will be in the air.

Dust concentration. The excavation is diluted and the polluted air is discharged outdoors, so that the harmful dust in the workplace is diluted to the corresponding maximum allowable concentration. During ventilation and exhaust, the airflow containing hazardous substances should not pass through the worker's breathing belt.

Raymond abrasive feed dust collector may fail due to the following reasons:

1.Broken or clogged filter bags. The filter bag is the core component of the dust collector, and if the filter bag is damaged or blocked, it will affect the normal operation of the dust collector.

2.Failure of electrical equipment. The operation of the dust collector needs the support of electrical equipment, and if the electrical equipment has a fault, such as poor switch contact, short circuit of wires, etc., it will affect the normal operation of the dust collector.

3.The dust collector's cleaning system is faulty. The ash cleaning system is another important part of the dust collector, if the ash cleaning system fails, it will cause the dust collector to be unable to clean the filter bag in time, resulting in the filter bag blockage.

In order to solve the problem of failure of Raymond abrasive inlet dust collector, the following measures can be taken:

1.Regularly inspect the condition of the filter bag, replace or clean the filter bag when problems are found, and bring it to the forest.

2.Regularly inspect the cleaning system to ensure that the cleaning system is operating properly.

3.Pay attention to whether the electrical equipment of the dust collector is normal during use, and repair or replace it in time if there is any abnormality.

In summary, there can be many reasons for the failure of Raymond abrasive feed dust collectors, but as long as we check and maintain them regularly, they can be avoided.
