The 3R1510 Raymond Mill is a classic dry-type grinding equipment engineered for small-to-medium scale non-metallic mineral powder processing. As a high-efficiency model in the 3R series, it features a compact vertical structure that minimizes floor space while delivering complete integrated functionality—from raw material feeding and grinding to classification and finished powder discharge.
Designed specifically for non-flammable minerals with Mohs hardness ≤7 and moisture content ≤6%, this mill is widely applicable to limestone, calcite, bentonite, gypsum, talc, dolomite, barite, feldspar, kaolin, marble, and similar materials.
Finished product fineness is precisely adjustable between 80–325 mesh, ensuring uniform particle size and high screening efficiency (>98%). Upgraded wear-resistant rollers and rings guarantee stable operation, low failure rate, energy efficiency, minimal dust emission, and low noise levels. Simple operation and easy maintenance significantly reduce labor and operational costs.
Working Principle
Raw materials are first crushed to ≤20mm by a jaw crusher, then conveyed to the storage bin via bucket elevator and evenly fed into the grinding chamber by an electromagnetic vibrating feeder.
Inside the main unit, grinding rollers press tightly against the ring under centrifugal force, crushing materials through compression, shearing, and grinding actions. The ground powder is lifted by airflow from the blower and classified by the analyzer above. Qualified fine powder enters the cyclone collector as final product, while coarse particles fall back into the grinding chamber for re-processing, forming a closed-circuit system.
Excess air is purified by a dust collector before atmospheric release. The entire process operates in a sealed dry environment, minimizing dust pollution and meeting international environmental standards.
