Description

What is a Basalt filter bag?

Basalt filter bag is made of a new type of high-temperature and efficiency filter material with reasonable structure and excellent performance. It is made of high count rock fiber filaments that are divided into velvet needles. It is composed of continuous basalt fibers, glass fibers and high silicon dioxide content.

The basalt filter bag fills the gap in the high-temperature 350 ℃ synthetic fiber needle punched filter material bag. It has great heat resistance, flame retardant ability and anti-corrosion effects.

It has three fiber porous structure with high fiber porosity, low gas filtration resistance and higher filtration efficiency than woven filter material .The filtration speed is also about twice that of woven filter material.

What are the special production processes for Basalt filter bags?

The Basalt filter bag is made of Basalt needle felt. The most traditional Basalt needle felt on the market only requires acupuncture, singeing, heat setting, and rolling before use. However, in complex working conditions with special and high filtration requirements. Special production procedures are used to improve the performance and efficiency of filter bags.

Filter bags can be treated with singeing, calendaring, water and oil repellent coating, PTFE impregnation and lamination as per customer’s demand and specifications.

How to check what kinds of filter bag is suitable for the bag house?

When old filter bag requires replacement:

Once you remove the filter bag from the filter housing, you can just take some measurements and pictures to send them to us. We would be able know your filter bag specifications using this method.

If you are able send us the samples, we can analyse the sample bag material and treatment.

We can make a sample for you to test its fitment with your bag house within a few days.

When you want to install a new filtration system and need some advice:

1. We will send you a configuration to fill it according to your specifications and conditions like temperature, chemical content and others. After you send it back to us .We will inform you about what kind filter bag is suitable for you.

2. Our engineers can arrange online meeting with your engineer or provide you with the configuration based on your demand.

What are the advantages of Basalt filter bags?

Advantages of Basalt filter bags:

The biggest advantage of basalt is its high temperature resistance, flame retardant ability. Which can reach 350 ℃ . It has strong acid and alkali resistance which prevents corrosion.

Due to its resistance to acid and alkali corrosion, it can be used for dust removal and filtration of acid and alkali gases.

The mechanical strength is high and the elongation is low. The fracture strength of rock fibers is generally above 3000N and the fracture elongation is only 3%. Therefore, the size of the cloth bag is stable and the mechanical performance is excellent.

Rock fiber fabrics have high porosity, good breathing ability and low no-load pressure loss.

The dust removal and filtration efficiency is high, which can intercept more than 99% of impurities, especially for particles with a diameter of less than 0.5mm.

The surface of fabric bags is smooth, easy to clean, and easy to operate and maintain.

Strong adaptability to smoke concentration and can be used in environments with high smoke and dust content.

Long service life of basalt dust removal bags.
