Principle of Edge Runner Mill:
Edge Runner Mill Operates on the principle of crushing and grinding.
Heavy rollers grind material by rolling over it.
Construction:
Grinding Surface: Flat or slightly concave surface.
Rollers: Heavy cylindrical rollers that rotate around a central pivot.
Feed Mechanism: Hopper for material input.
Discharge Mechanism: Outlet for processed material.
Working:
Material is fed onto the grinding surface.
Rollers rotate around the pivot, crushing and grinding the material by rolling over it.
The continuous action ensures thorough grinding and mixing.
Processed material is discharged from the outlet.
Uses:
Grinding and mixing of minerals, ores, chemicals, and pharmaceuticals.
Merits:
Simple and robust design.
Effective for grinding and mixing.
Suitable for large-scale production.
Demerits:
High energy consumption.
Wear of rollers and grinding surface.
Limited to materials that can withstand high pressure.
