Capacity: 0.5-25T/H
Input size: 10-20mm
Performance Advantages
Safe, reliable and environmental protection: Using high-efficiency pulse dust collector, to reduce dust and noise pollution, excellent results of environmental protection.
Low investment and high efficiency: In the same product fineness and power consumption, the investment cost is lower, recovery cycle is shorter and yield is 45% more than jet mill.
Low loss and high fineness: tear and wear parts use high-quality wear-resistant materials, the serve life is more than a year, final fineness up to D97 ≤ 5μm at one time.
Working Principle
The motor drives the main shaft and every turnplate through the reducer.The reducer drives dozens of rollers to rotate against race way of ring through pin. Small material crushed by hammer crusher is transported into hopper by elevator, and then vibrating feeder shall feed material to the central part of upper turnplate evenly.The material falls to circle under the centrifugal force and comes down to raceway of ring to be crushed into powder.

FAQ
Can the MW ring‑roller micro‑powder mill realize automatic operation?
Equipped with intelligent electric control cabinet, it realizes automatic control over feeding, grinding, classification and collection. It supports connection to upper‑level central‑control system for remote parameter monitoring and fault alarm display. Automatic mode reduces on‑site labor and human‑operation errors, suitable for stable continuous production of medium‑and‑large‑scale powder‑making projects.
How is product collection and packaging achieved on the MW Ring Micro Powder Mill?
Qualified ultrafine powder enters the cyclone and pulse collector for gas-solid separation and is discharged by a rotary valve. As the powder is extremely fine, ton-bags or vacuum packing with pneumatic conveying to silos is used; negative pressure ensures high recovery with no dust.
Can the MW ring‑roller micro‑powder mill process petroleum coke and graphite?
Yes. Petroleum coke and graphite are moderate‑hardness non‑flammable‑explosive materials. Strictly control feed moisture to avoid chamber caking and blockage. Graphite can reach high‑mesh fineness. Control feeding rate for petroleum coke to prevent main‑unit overload. Do not process modified flammable‑explosive graphite‑based products.
Is a drying system available as an optional accessory for the MW ring‑roller micro‑powder mill?
Drying system is available as optional accessory. When raw‑material moisture exceeds 6% limit, the drying unit pre‑reduces moisture to prevent chamber sticking and blockage, securing grinding efficiency and powder quality. It is non‑standard equipment. Evaluate necessity based on incoming‑material moisture, widely adopted for powder‑making with wet mineral raw materials.
What is the typical service life of grinding rollers and rings for MW ring‑roller micro‑powder mill?
Service life of grinding rollers and rings depends heavily on material hardness, feed size and operating load. For ordinary Mohs‑3‑4 non‑metallic ore under normal conditions, service life ranges from several months to about one year. Harder materials speed up abrasion and shorten service life. Strict feed‑size control and block‑lump rejection effectively extend roller‑ring working cycle.
What hourly capacity do the MW Ring Micro Powder Mill models each reach?
Models MW Ring Micro Powder Mill 600, 800, 1000 and 1250 vary strongly with fineness: the coarse end (325–800 mesh) reaches several to over ten t/h, while above 2000 mesh it drops to hundreds of kg to 1–2 t/h. Set the target fineness first, then check capacity—each finer step cuts output. Ask about the finest-grade output when choosing a model size. Multi-ring, multi-roller geometry lets material be repprocessedly rolled and sheared for high ultrafine efficiency.
