20 tph raymond mill fly ash grinding plant in Thailand

Fly ash is a fine ash powder produced by coal-fired power plants. They are generally stored in silos or pits for later recovery in the construction sector. It's commonly used as structural fill for road construction and fly ash can be used to make bricks, ceramic tiles, plaster, Portland cement, and ready-mix cement.

Raymond mill fly ash powder grinding plant

Raymond mills are suitable for grinding fly ash powder, but the selection of Raymond mills and operation methods need to be determined according to specific needs and conditions. Fly ash powder has certain abrasiveness and hardness, so it is recommended to select Raymond mills with wear-resistant materials and advanced grinding technology. In addition, it is necessary to strictly control the feeding particle size, grinding concentration, water content and other parameters to ensure the grinding effect and product quality. It is also recommended to regularly maintain and replace wear parts to ensure the stable operation of Raymond mills and prolong their service life.

The structure of Raymond mill 

1.Main frame

The main frame is the supporting structure of the whole Raymond mill, which bears the weight of the whole equipment and ensures its stability during operation.

2.Grinding roller device

The grinding roller device is the core part of Raymond mill, which is mainly composed of grinding roller, grinding ring, and spring pressure device. The grinding roller rotates around the grinding ring under the action of spring pressure device, and the material is crushed and grinded between the grinding roller and grinding ring.

3.Airflow system

The airflow system is mainly composed of fan, air duct, and powder collector. The fan generates airflow to transport the crushed material to the powder collector for collection.

4.Transmission system

The transmission system is mainly composed of reducer, motor, and coupling. The motor drives the reducer to rotate, and the reducer further drives the grinding roller device to rotate.

5.Lubrication system

The lubrication system is mainly composed of lubricating pump, lubricating pipe, and lubricating point. The lubricating pump pumps lubricating oil to the lubricating point to ensure the normal operation of the equipment.

In addition, Raymond mill may also include other auxiliary devices such as material feeder, powder discharger, etc., depending on the specific requirements of the production process.

People Also Frequently Asked For - FAQ:

1.  How does a Raymond mill work?

A Raymond mill works by using a rotating roller to grind materials into fine particles. The rollers are connected to a central shaft, which rotates and moves the rollers along the grinding ring. As the rollers make contact with the grinding ring, they crush the material and break it down into smaller pieces.

2. What is the difference between a ball mill and a Raymond mill?

Ball mill is a kind of common equipment for material grinding in mineral processing production line. The ball mill has high output and higher efficiency. Raymond mill is suitable for fine powder processing of graphite, talc, kaolin, limestone and other materials with high material fineness requirement.

3.How do you process fly ash?

In the sorting system, the coal ash is sorted by the separator to separate the qualified pulverized coal and large particles in the coal ash; in the grinding system, the grinding mill grind coarse fly ash into qualified fine powder.
