Mineral Sizer
CSTMG’s Mineral Sizer is a high-efficiency crushing solution for coal, soft ores, and abrasive materials. Featuring dual rotating shafts with intermeshing teeth, it delivers precise sizing with minimal fines. The robust design handles wet, sticky feeds without clogging while reducing energy consumption by 30-50% compared to traditional crushers. Ideal for mining, recycling, and mineral processing applications requiring high capacity and low maintenance.

CSTMG Mineral Sizer Features
Wide Material Adaptability. Equipped with interchangeable teeth (straight/spiral/wolf-tooth) for coal, limestone, and gangue. Handles materials up to 150MPa hardness and 25% moisture, excelling in brittle/soft ore crushing.
Precise Size Control. Adjustable roller gaps (10-200mm) ensure uniform output with ≤5% over-crushing. Ideal for strict sizing requirements in coal washing or aggregate production.
Multi-Layer Overload Protection. Hydraulic coupling + shear-pin coupling + electrical interlock prevents motor damage from oversized materials or tramp iron, reducing downtime by 70%.
Robust & Compact Design. Tungsten carbide teeth (HRC≥65) withstand abrasion for 30,000+ hours. Modular structure allows on-site tooth replacement in 2 hours, cutting maintenance costs by 50%.

Mineral Sizer Handling Materials
High-Moisture & Sticky Materials. Handles wet coal, clay-rich ores, and sticky minerals (up to 25% moisture) without clogging, thanks to self-cleaning tooth design and non-clogging gaps.
Abrasive & Hard Ores. Crushes iron ore, quartzite, and slag (hardness ≤ 150MPa) with tungsten carbide teeth (HRC≥65), offering 3x longer wear life than standard crushers.
Friable & Brittle Minerals. Minimizes over-crushing (fines generation <5%) for salt, oil shale, and limestone, preserving lump product quality for downstream processing.
Mixed & Heterogeneous Feeds. Processes coal with gangue, demolition waste, or recycled concrete efficiently, with adjustable tooth configurations (straight/spiral/wolf-tooth) for optimal fragmentation.

- Laser-aligned bearing installation for perfect shaft concentricity.
- Computer-controlled torque application for all fasteners.
CSTMG Mineral Sizer Working Principle
The CSTMG Mineral Sizer operates on an advanced dual-roll crushing principle that delivers superior size reduction for various materials.
As raw material enters the crushing chamber, the counter-rotating toothed rollers grip and progressively break down the feed through a combination of compressive and shear forces.
The intermeshing teeth create multiple crushing zones that ensure uniform particle sizing while minimizing fines generation to less than 5%.
A key advantage is the adjustable gap control system (10-200mm range) that allows precise output sizing customization. The self-cleaning tooth design prevents material buildup, enabling reliable processing of sticky or high-moisture materials (up to 25% water content).
Compared to traditional crushers, this innovative mechanism offers 30-50% better energy efficiency and significantly lower wear rates
