Ultrafine Raymond Grinding Mill | Micro Powder Grinding Expert-The Ideal Solution for High Fineness Powder Processing of 325-2500 Mesh
Ultrafine Raymond Grinding Mill | Micro Powder Grinding Expert — The Ideal Solution for High-Fineness Powder Processing of 325-2500 Mesh
In the field of non-metallic mineral processing, ultrafine powder technology is advancing from "fine grinding" to "ultrafine" and "functionalization." The coatings, plastics, paper, rubber, and cosmetics industries are placing higher demands on powders—requiring not only fineness of 325-2500 mesh but also concentrated particle size distribution, no over-grinding, high whiteness, and high purity.
The Ultrafine Raymond Grinding Mill is a newly upgraded micro-powder grinding equipment based on traditional Raymond mill technology. It is suitable for non-flammable, non-explosive materials with Mohs hardness ≤7 and moisture ≤6%, including over 100 minerals such as limestone, calcite, marble, barite, talc, kaolin, bentonite, dolomite, gypsum, graphite, and wollastonite. Using the centrifugal rolling + ultrafine classification principle, it can grind materials to 325-2500 mesh ultrafine powder, with uniform fineness, high output, and low energy consumption.
This equipment can be equipped with a PLC automatic control system and a pulse baghouse filter to achieve automated, clean production. It has been widely used in the field of non-metallic mineral ultrafine powder processing both domestically and internationally, making it an ideal choice for you to explore high-value-added powder markets.
Ultrafine powder produced by the micro powder grinding mill is widely used in the following industries:
| Application Industry | Typical Fineness | Application Value |
|---|---|---|
| Coatings Industry | 800-1250 mesh (15-10μm) | Improves opacity, leveling, weather resistance, reduces titanium dioxide usage, lowers coating costs |
| Plastics Industry | 600-2500 mesh (20-5μm) | As functional filler, improves rigidity, heat resistance, dimensional stability, and surface gloss of plastic products |
| Paper Industry | 600-1250 mesh (20-10μm) | Improves whiteness, smoothness, opacity, and printability of paper, suitable for high-grade coated paper |
| Rubber Industry | 400-1250 mesh (38-10μm) | Improves abrasion resistance, tensile strength, tear strength, and processing performance of rubber products |
| Sealants & Adhesives | 600-1250 mesh (20-10μm) | Improves thixotropy and bond strength of sealants, increases product volume and sag resistance |
| Cosmetics Industry | 1250-2500 mesh (10-5μm) | Improves skin feel, adhesion, and coverage of powders, ensures high purity and safety |
| Ceramics Industry | 325-800 mesh (45-15μm) | Improves green body density and strength, controls thermal expansion coefficient and yield |
| Feed & Fertilizer | 80-325 mesh (180-45μm) | Increases specific surface area, improves digestion absorption, fertilizer utilization and release rate |

Working Principle
The working principle of the ultrafine Raymond grinding mill is based on centrifugal rolling and ultrafine air classification. The entire system consists of the main unit, classifier, pulse baghouse filter, high-pressure fan, and electrical control cabinet:
1. Feeding
After being crushed to the required size (typically ≤30mm), the material is uniformly and quantitatively fed into the main unit's grinding chamber via a bucket elevator and an electromagnetic vibrating feeder.
2. Grinding
Grinding rollers are suspended on a roller hanger. Under the centrifugal force generated by spindle rotation, they tightly press against the grinding ring. Material is scooped up by shovel blades and thrown between the rollers and the ring, where it is crushed and ground into micro powder.
3. Ultrafine Classification
The ground micro powder rises with the fan's airflow to the classifier. The ultrafine classifier adjusts the speed of the classifying rotor via a frequency converter to separate qualified fine powder from coarse powder. Qualified fine powder passes through the classifier wheel to the collection system, while coarse powder is rejected and falls back into the grinding chamber for regrinding, forming a closed circuit that ensures concentrated particle size distribution and prevents over-grinding.
4. Collection & Dust Removal
Qualified micro powder enters the pulse baghouse filter with the airflow and is collected by the filter bags. The collected finished product is discharged through a discharge valve and conveyed by a screw conveyor to the finished product silo or packaging machine. Purified exhaust gas is discharged at compliant levels, ensuring a clean, dust-free working environment.
5. The Core Function of the Ultrafine Classifier
Effectively controls final fineness within the 325-2500 mesh range
Significantly improves product sieve residue rate, ensuring product pass rate
Increases finished product yield and reduces grinding energy consumption
Enables the system to achieve ideal micro powder in a single grinding pass
