Raymond Mill

Raymond Mill

Capacity: 1-50TPH
Feeding Size: ≤30mm
Discharging Size: 0.045-0.18mm
Handling Materials: Limestone, calcite, barite, talc, gypsum, etc.

Raymond mill grinds non-metallic minerals (limestone, gypsum) into 80-325 mesh powders via roller compression and air classification. Ideal for producing fillers and industrial powders, it offers 1-50t/h capacity with 30-40% energy savings versus ball mills. Not suitable for hard (>7 Mohs) or sticky materials.

Advantages

01.

Energy Efficient

Saves 30-40% power vs ball mills for 80-325 mesh powder production, thanks to roller grinding and airflow classification synergy.

02.

Precise Grading

Dynamic analyzer ensures ±5% particle uniformity (200-mesh limestone), ideal for filler/paint industries requiring strict specs.

03.

Compact Design

Vertical structure occupies 50% less space than horizontal mills, reducing plant layout constraints and installation costs.

04.

Low Wear

Grinding rollers and rings for soft minerals (<7 Mohs) last 2-3x longer than abrasive ore milling systems.

How Does A Raymond Mill Work

1.Material Feeding: Crushed raw materials (≤30mm) enter the grinding chamber via a screw conveyor, falling between rotating rollers and the grinding ring.

2. Roller Grinding: Spring-loaded rollers compress and shear materials against the rotating ring, breaking particles into finer powders through mechanical force.

3. Air Classification: A blower circulates airflow, lifting ground powder to the analyzer wheel where oversized particles are rejected back for regrinding.

4. Product Collection: Fine powder (80-325 mesh) passes the analyzer into a cyclone collector, while coarse particles repeat the grinding cycle.
