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.
