1.
Safe, reliable and environmental protection: Using high-efficiency pulse dust collector, to reduce dust and noise pollution, excellent results of environmental protection.
2.
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.
3.
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.
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.
Declining output often comes from worn sleeves/rings, off-set classifier speed, low fan airflow, clogged bags or uneven feed. Check wear-part thickness, clean bags, correct classifier frequency and airflow, confirm no metal via separator, and contact the maker if needed.
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.
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.
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.
It`s mature for heavy-calcium ultrafine powder, grinding calcite to 800–2500 mesh for high-end fillers in plastics, coatings, paper and rubber. Its turbine classification keeps size narrow and brightness loss low, suiting continuous ultrafine mass production.
