The double-toothed roll crusher, also known as the 2PGC toothed roll crusher, features roll surfaces available in coarse-toothed and fine-toothed configurations. Tooth profiles can be customized to meet specific user requirements. Sandreck’s toothed double roll crusher allows for adjustable output sizing and is ideal for processing brittle and soft materials.

The machine is equipped with two toothed rolls. Roll surface options include large/small “wolf-tooth” (conical) teeth, specialized coke-cutting teeth, annular teeth, longitudinal bar teeth, and large plate teeth. It is suitable for medium or coarse crushing applications requiring a finished particle size of 10–300 mm, where minimal fines and a high proportion of granular product are desired.

The stone crusher accepts large feed sizes and offers adjustable discharge sizing. It is capable of crushing materials with a compressive strength of up to 160 MPa. It serves industries such as sintered ore, coal, cement, silicates, glass, and ceramics, and is suitable for crushing brittle materials of low to medium hardness.

Drive systems can be configured as either V-belt or direct coupling (rigid connection) based on user requirements. In mining locations lacking an electrical power supply, the double roller crusher can be adapted to run on a diesel or gasoline engine.

Double Toothed Roll Crusher Working Principle

The double-toothed roll crusher utilizes the high compressive force generated by the counter-rotation of two wear-resistant alloy toothed rolls to crush material.

Upon entering the crushing chamber, the material is subjected to the gripping force of the rotating roll shafts, forcing it to pass between the two rolls. Simultaneously, the material undergoes crushing, shearing, and grinding actions, causing it to fracture. The resulting small particles are ejected downwards through the gap between the rolls along the tangential path of their rotation. Any material particles larger than the gap continue to be crushed until they are reduced to small enough sizes to pass through.

Advantages of Toothed Double Roll Crusher

1. This series of rock crushers offers numerous advantages, including a high crushing ratio, low sensitivity to material moisture content, minimal clogging or sticking, low noise and vibration levels, reduced dust generation, low energy consumption, a compact footprint, and ease of maintenance.
2. Equipped with an automatic hydraulic retraction mechanism, the double roller crusher effectively prevents damage to the toothed rollers caused by iron fragments, wood blocks, or pliable objects.
3. The crushed product is uniform in size, with no oversized particles.
4. Multiple protection and interlocking systems—incorporating mechanical, electrical, and hydraulic components—are employed to effectively safeguard the motor, the crusher itself, and the entire system.

Double Toothed Roll Crusher Applications

Suitable Materials: Double toothed roll crusher is suitable for crushing iron ore, quartz, potash/soda feldspar, limestone, river pebbles, copper ore, bauxite, barite, basalt, steel slag, cement clinker, waste materials, concrete, coal, coke, water-quenched slag, furnace slag, clay, fertilizers, chemical raw materials, etc.
Applications: The double roller crusher machine is widely used in industries such as mining, sand and gravel yards, thermal power generation, metallurgy, chemicals, and construction materials.
