Equipment introduction
The Double Toothed Roll Crusher is a core equipment in clay brick production for raw material pre-processing. It utilizes two counter-rotating toothed rollers to shear and crush materials (e.g., clay, shale, coal gangue) into 3-10mm particles, ensuring optimal sizing for mixing and extrusion processes. The mechanism of the double tooth roll crusher is to crush materials by a pair of opposite rotating rollers with teeth on roller surface. The raw materials go through the hopper and drop between the rollers for crushing, and then naturally fall down. There is certain gap between rollers when rotating in opposite directions, the discharge grain size can be achieved by adjusting this gap.

Equipment Specification

Features:
1. Toothed Roll Design: Wear-resistant alloy teeth enable combined shearing and crushing.
2. Adjustable Gap: Hydraulic/mechanical gap adjustment (1-20mm) for precise output sizing.
3. Overload Protection: Hydraulic cushioning against foreign objects (e.g., metal scraps).
4. Modular Tooth Segments: Individual teeth replacement reduces maintenance costs.
Function:
Breaks bulk clay or hard materials (e.g., coal gangue) into uniform particles, preventing downstream issues like extruder jamming or brick cracking caused by uneven sizing.
Advantages:
1. Energy-Efficient: 30-40% lower power consumption vs jaw crushers.
2. Low Over-Crushing: Toothed rollers minimize fines, increasing clay utilization by 15%.
3. High Adaptability: Handles wet materials (≤25% moisture) or impure raw mixes.
