Double-tooth roll crusher

We focus on manufacturing high-performance double-roll sand making machines. Our equipment is meticulously designed to efficiently process over 200 types of hard materials, including river pebbles, cobblestone, limestone, quartzite, and more!
Our roll crusher is specifically designed to meet the production demands of small, medium, and large sand making plants. We offer ready-to-ship machines equipped with our patented wear-resistant roller shells, which feature exceptional abrasion resistance, durability, and heat resistance. No wear parts are needed; with intelligent one-button control, operation is extremely convenient and efficient.

Factory Direct Stock

The tooth roll crusher is a high-performance piece of mining equipment, primarily composed of two sets of high-strength, wear-resistant toothed rolls. During operation, the two rolls rotate in opposite directions, crushing the material through shearing, squeezing, and other actions. With a compact structure and simple operation, it is suitable for coarse and medium crushing of materials with hardness below medium, such as coal, coke, and ores. It features a large crushing ratio, high efficiency, low energy consumption, and convenient maintenance. In particular, it has strong adaptability to sticky and wet materials and is not prone to clogging. It is widely used in coal preparation, metallurgy, chemical engineering, and other fields.

Double‑Tooth Roll Crusher – Material Crushing Showcase

Working Principle

The tooth roll crusher utilizes two wear‑resistant alloy toothed rolls that rotate in opposite directions to generate high extrusion force for crushing materials. Once the material enters the gap between the two rolls (the V‑shaped crushing chamber), it is broken down to the required particle size through squeezing, shearing, and grinding/abrasion actions. The crushed material is then discharged by conveying equipment.

Advantages  Performance

1. Compact structure and small footprint.

2. Easy to maintain and service.

3. Suitable for dry, wet, muddy, and sticky ores.

4. Uniform product size.

5. Minimal production of fines and powder.

6. Dual overload and tramp‑iron protectio

Tooth shape classification

The tooth roll crusher offers a variety of tooth profiles, including strip teeth, wolf‑type teeth, square wave teeth, pointed wave teeth, rhombic teeth, and heavy‑duty large wolf teeth (with increased thickness, larger dimensions, and enhanced wear resistance), among other configurations。

Tooth Shape Showcase

In practice, customers should select the appropriate tooth shape based on the specific material being processed, as well as the required feed and discharge particle sizes. A tooth shape that is well‑suited to crushing their particular material can significantly improve the efficiency of the tooth roll crusher in the coal crushing plant, thereby boosting overall production capacity.
