A 2PG roller crusher for quartz grits is a type of double-roll crusher designed for crushing medium-hard materials like quartz into smaller granules or grits. Here’s a detailed breakdown of its features, working principle, and applications:

Key Features of 2PG Roller Crusher for Quartz Grits:
1. Double Roll Design:
– Two counter-rotating rollers crush the material by compression and shear forces.
– Adjustable gap between rolls controls the output size (typically 1–10mm for quartz grits).
2. High Crushing Efficiency:
– Suitable for brittle materials like quartz, producing uniform particle sizes with minimal fines.
3. Durable Construction:
– Rollers are often made of high manganese steel or tungsten carbide to resist abrasion from hard quartz.
4. Overload Protection:
– Spring or hydraulic system prevents damage from uncrushable materials (e.g., metal fragments).
5. Low Dust & Noise:
– Enclosed design reduces dust emission, important for silica (quartz) processing due to health risks.
Working Principle:
1. Quartz material is fed into the gap between the two rollers.
2. The rotating rollers draw the material inward and crush it via compression and shear forces.
3. Crushed grits exit below the rollers, with size determined by the roll gap setting.
Applications:
– Producing quartz grits for abrasives, glass manufacturing, ceramics, or foundry sand.
–
e-crushing before ball milling in mineral processing plants.
Advantages Over Other Crushers:
✔ More uniform particle size than hammer crushers (less over-crushing).
✔ Lower energy consumption than jaw/cone crushers for medium-hard materials like quartz.
Considerations When Selecting:
– Roller speed and surface texture (smooth/toothed) affect output shape and fines generation.
– Moisture content should be low (<10%) to prevent clogging.
