Ultrafine Grinder
High-fineness powder processing relies on high-efficiency and precision grinding equipment. RICHI ultrafine grinder is a reliable solution, capable of processing various low-to-medium hardness materials into ultrafine powder ranging from 80 to 3000 mesh (approx. 178μm to 5μm). It is widely used in feed, pharmaceutical, chemical, non-metallic mineral, environmental protection and many other industries.
According to different customer needs, RICHI designs different equipment models.
Ultra-fine Grinding Machine
If you are looking for professional equipment for ultrafine powder production, RICHI ultrafine pulverizer is your ideal choice.
Pulverized High-fineness Powder Production
Adopting the combined grinding principle of impact, shearing and grinding, the RICHI ultrafine pulverizer is equipped with a built-in classification system. The final powder fineness is freely adjustable from 80 to 3000 mesh. Certain models achieve one-time ultrafine grinding with D97 ≤ 5μm, featuring narrow particle size deviation to meet high-precision processing demands across industries.It integrates high efficiency, energy saving, controllable accuracy and stable operation.

RICHI Crafted, Fully Trusted.
Equipment Structure
With vertical precision structure and modular layout, the machine is easy to disassemble and maintain. All core components comply with RICHI heavy-duty manufacturing standards.
Frame
Fabricated from thickened steel plates with integral welding and stress-relief annealing treatment, the frame delivers high rigidity, stable center of gravity and excellent shock resistance. Standard anchor bases enable flexible installation in workshops and clean production rooms.
Feeding System
Equipped with a variable-frequency feeder for uniform and adjustable feeding volume, effectively preventing grinding chamber blockage caused by overfeeding. A built-in magnetic separator removes metal impurities to protect key components. Anti-rebound baffles are adopted to ensure operational safety.
Grinding Main Unit
Features a vertical main shaft with imported SKF bearings, which provide high precision, strong wear and impact resistance, low friction coefficient, low operating temperature and low noise. It fully supports long-term high-intensity continuous operation.
Multi-layer grinding rollers and rings are forged from special wear-resistant alloy for even abrasion and long service life. Some models adopt mosaic alloy wear plates to enhance durability.
The fully sealed grinding chamber reduces dust leakage and material loss. Grinding temperature is adjustable by controlling cooling water. An optional refrigeration system supports low-temperature grinding down to -45°C, suitable for heat-sensitive materials.
Classification System
A built-in high-speed turbo classifier with variable-frequency speed control precisely adjusts impeller speed for accurate powder screening. Coarse powder falls back for regrinding, while qualified fine powder is delivered to the collecting device along airflow. It ensures uniform particle size and centralized distribution without additional screening equipment.
Discharging & Dust Removal System
Combined design of negative pressure pneumatic conveying, cyclone collector and pulse dust remover ensures smooth discharging and zero dust emission. The high-sealing powder collector minimizes material waste, while the pulse dust collector purifies exhaust air to meet high cleanliness requirements for pharmaceutical and food industries.
Transmission System
Direct coupled drive by motor and reducer ensures high transmission efficiency, sufficient torque, stable operation and low noise. Equipped with Siemens BEIDE motors, it features low energy consumption and strong power. Multiple motor power options are available for different output demands.

FAQs
Should you have any questions, RICHI will provide you with professional answers.
What is the maximum powder fineness? Is it adjustable?
The fineness is fully adjustable within 80–3000 mesh (178μm–5μm). Premium models achieve D97 ≤ 5μm ultrafine powder in one operation. The built-in turbo classifier accurately controls particle size via frequency conversion speed regulation. Coarse powder regrinding ensures uniform and consistent finished powder without extra screening.
Can grinding temperature be controlled? Is it suitable for heat-sensitive materials?
Yes. The sealed grinding chamber adopts adjustable cooling water circulation. An optional refrigeration system reduces temperature to -45°C, effectively preventing thermal deterioration of pharmaceutical raw materials, food additives and other heat-sensitive materials, and guaranteeing high-quality final products.
Do SKF bearings require regular maintenance?
Routine maintenance is simple. Regularly check and replenish lubricating oil to avoid dry friction. Clean dust around bearings periodically to prevent particle intrusion into the bearing chamber. Simple daily inspection ensures long-term stable bearing operation.
Is finished powder pure and free of impurities?
Completely guaranteed. The magnetic feeder removes metal contaminants. The bearing-free and screw-free internal chamber structure avoids falling foreign matter. The integral stainless steel fully sealed design complies with GMP standards and effectively prevents cross-contamination.
