5R4121 Raymond Mill
Factory Direct Supply | 80‑325 Mesh Adjustable | Capacity:8‑15t/h | 1‑Year Warranty | Custom Voltage Available
5R4121 Raymond Mill is high-output large-sized grinding equipment upgraded from traditional Raymond mill, designed for large-scale non-metallic mineral powder processing. It adopts a 5‑roller vertical suspension grinding structure with larger grinding cavity and much higher working efficiency.
It completes feeding‑grinding‑classifying‑collecting‑dust removal automatically. Suitable for non‑flammable minerals with Mohs hardness ≤7 and moisture ≤6%, including limestone, calcite, dolomite, gypsum, talc, bentonite, barite, feldspar, quartz stone, marble, etc.
Finished fineness is adjustable from 80‑325 mesh with uniform powder. Upgraded thickened wear‑resistant parts ensure stable performance, low failure rate, energy saving, low dust and noise. Easy operation and maintenance reduce labor cost.
Widely used in large mineral powder plants, building materials factories, chemical raw material factories and heavy-duty powder projects. Factory direct supply with custom configuration and voltage, available for global delivery.
Working Principle
|
Large materials are crushed to ≤30mm, sent into storage bin by bucket elevator, then fed evenly into grinding chamber by electromagnetic feeder. Inside the main machine, 5 rollers press rings under centrifugal force to grind materials. Fine powder is classified by high‑speed analyzer and collected by cyclone collectors. Coarse powder falls back for re‑grinding to form closed‑loop production. Exhaust gas is purified by pulse dust collector. Whole dry‑type sealed operation meets strict environmental protection standards. |
Core Advantages
High Efficiency & Large Capacity: 5‑roller design expands grinding area greatly. Stable capacity 8‑15t/h with over 99% screening rate, perfect for mass large-scale powder production.
Durable & Long Service Life: Wear parts made of extra thick high‑manganese steel. Reinforced main frame supports 24‑hour continuous stable heavy load operation.
Energy‑Saving & Eco‑Friendly: Sealed dry‑type system with pulse dust collector for ultra low dust and noise. No wastewater discharge. Optimized large power motor saves over 25% power consumption.
Precise Fineness Control: 80‑325 mesh adjustable via analyzer speed. Uniform particle size and high‑purity finished powder.
Stable Operation & Low Failure Rate: Integral heavy casting structure reduces vibration and breakdowns. Strict assembly process improves overall stability.
Easy Maintenance & Low Labor Cost: Standardized universal spare parts easy to purchase. Centralized control cabinet supports single‑person simple operation.
Wide Application: Process dozens of non‑metallic minerals. Custom voltage (380V/415V/440V/60Hz) for global markets.
Factory Direct Supply & High Cost Performance: Direct manufacturer with no middlemen. Support complete production line design, sample testing and full after‑sales service.
