The installation of Cronus 4R3220 small raymond mill is in progress

4R3220 small Raymond Mill is a small-scale Raymond Mill specially developed by Cronus Company for grinding mineral powder. It mainly meets customers’ needs for small investment, quick results, and fast cost recovery. This type of Raymond Mill is highly popular in India, Indonesia, Nigeria, Pakistan, and other foreign markets.

Small-scale Raymond mills like the 4R3220 offer low upfront investment (30-50% cheaper than large models) while maintaining high energy efficiency (45 kW blower motor reduces power consumption by 18% compared to older 37 kW versions). This aligns with the growing trend of decentralized production, where SMEs prefer modular equipment to avoid overcapacity risks. For example, in the lithium battery material processing sector, small mills are widely adopted for batch production of cathode materials, with 63% of users reporting ROI within 1.5 years.

Equipped with pulse dust collectors (emission ≤20mg/m³) and noise reduction enclosures (≤85dB), the 4R3220 complies with China’s 2025 Industrial Pollutant Discharge Standards. This addresses the urgent needs of 65% of mining enterprises facing environmental rectification orders. For instance, in Anhui province, 38% of limestone processing plants have replaced outdated equipment with the 4R3220 to avoid fines.

The 4R3220 Raymond Mill enjoys the advantages of high equipment maturity, stable operation, sufficient spare parts and low price. This is also one of the reasons why the 4R3220 Raymond Mill is so popular.

The 4R3220’s vertical structure design (occupying only 15m²) and quick assembly (installation completed in 3 days) enable rapid deployment in remote mining areas or urban construction sites. Its adjustable fineness range (80-325 mesh) meets diversified demands, such as:

• Building materials: 40% of users employ it to produce 200-mesh gypsum powder for drywall.
• New energy: 27% use it to grind 325-mesh lithium mica for battery anode materials.
• Chemical industry: 18% process activated carbon with 80-mesh particle size.

Cronus Company is a wholly-owned subsidiary of Guilin Mining Company. We are the earliest state-owned enterprise in China to engage in the research and production of Raymond mill equipment. Founded in 1973, we are a national high-tech enterprise. We have over 50 years of history in the production of Raymond mills and possess rich experience in the manufacturing of mining equipment. The company has 12 production workshops, and its products include Raymond mills, ultra-fine mills, and calcium hydroxide production line equipment. The annual sales exceed 500 million yuan. We have over 200 production workers, more than 50 professional technicians, and over 20 after-sales service personnel.

Raymond mill： applies to kinds of stone powder plant, such as calcite, calcium carbonate, gypsum, talc, dolomite, the final fineness 40-400 mesh adjusted.

ring roller mill -superfine grinding mill: it’s also used for stone powder making plant, the difference between ring roller mill and raymond mill is the final fineness, ring roller mill’s fineness 300-3000 mesh adjusted.

Superfine grinding mill machine- the high-end stone powder grinding mill. The finished powder rate of this machine is relatively high, generally 2 microns contains> 50%. This kind of finished stone powder is the main raw material for stone paper production, high-end paints, and new materials. It is widely applied. However, this equipment is relatively expensive and is suitable for manufacturers that have requirements for fine powder of high-end finished products.
