Scheme for Processing Bamboo and Wood with Raymond Mill

Grinding Device

Adopt grinding rollers and rings with sharp teeth or special patterns to enhance the shearing and tearing effect on fibers; adjust the main machine speed to balance grinding efficiency and heat generation.

Air Classification System

Use a high-precision, high-speed dynamic analyzer to precisely control the fineness of the output powder and effectively separate qualified fine powder; equip with an adjustable fan air volume and pressure system for stable conveying of finished products.

Cooling System

Adopt large-scale water cooling or air cooling systems in key parts such as the main mill and fan bearings to remove grinding heat, control the powder outlet temperature, and ensure the quality of bamboo and wood powder.

Explosion-proof and Safety Measures

Use explosion-proof motors and electrical appliances, set up explosion vents in pipelines, cyclone collectors, etc., select pulse dust collectors with efficient dust removal and explosion-proof functions, and pass nitrogen gas if necessary to reduce explosion risks.

Feeding System

Use a stable feeder to ensure that bamboo and wood chips/splinters pre-crushed to a small size (e.g., < 20mm) enter the main machine evenly and continuously.

Process of Processing Bamboo and Wood with Raymond Mill

Raw Material Pretreatment

Slice the bamboo and wood, and use professional equipment to cut them into bamboo or wood chips with uniform thickness and appropriate size.

Drying Process

Commonly use natural drying and artificial drying methods to control the moisture content of bamboo and wood at about 10% - 15%, then screen and remove impurities to ensure stable and pure raw material quality.

Grinding and Powder Making

The pretreated bamboo and wood chips/splinters are fed into the main machine by the feeder. The specially designed grinding rollers and rings perform grinding. The fan blows the bamboo and wood powder into the analyzer for screening, and the qualified fine powder enters the cyclone collector for collection.

Tail Gas Treatment

The tail gas generated during grinding enters the pulse bag filter for purification. The dust is collected and recycled, and the purified tail gas is discharged up to the standard.

Key Points for Processing Bamboo and Wood with Raymond Mill

Clarify Requirements

Select models according to the target market's requirements for the fineness, output, cost and quality of bamboo and wood powder. The fineness requirements vary greatly in different industries. Large-scale production focuses on output, small enterprises pay attention to flexibility and cost performance, and high-end fields have strict requirements on quality.

Choose as Needed

If the target fineness is above 200 mesh and there are high requirements for whiteness and low temperature, a deeply modified Raymond mill can be selected, but the investment and maintenance costs are high. If the target fineness is 80 - 150 mesh, the wood powder machine is more economical, efficient and safe. For high-value-added fields such as food and medicine, the airflow mill is the best choice.

Attach Importance to Explosion-proof Safety

Bamboo and wood powder are flammable and explosive. Explosion-proof safety measures should be placed in the first place in equipment design and operation, and safety training for operators should be strengthened.

Summary

The entire process of processing bamboo and wood with a Raymond mill includes raw material pretreatment, feeding, grinding and pulverizing equipped with sharp grinding rollers and rings as well as a temperature control system, high-precision air separation for fineness adjustment, explosion-proof safety design, and pulse bag dust removal for exhaust gas treatment.
