Applications of double roller crushers

A double-roll crusher (also known as a twin-roll crusher or double-roll mill) is a common crushing equipment with a wide range of applications, primarily depending on the hardness, moisture content, and specific industrial requirements of the material. The following is a summary based on relevant information:

**Main Applicable Materials:** Double-roll crushers are suitable for brittle materials with medium to low hardness, such as coal, coke, limestone, iron ore, sintered ore, cement clinker, gypsum, glass raw materials, ceramic raw materials, river pebbles, and coal gangue.

1. For materials with higher hardness (such as iron ore and granite), a compressive strength of 147-245 MPa is typically required.

2. The equipment has certain requirements regarding the moisture content of the material; generally, the feed moisture content should not be too high to avoid affecting the crushing effect.

**Industrial Applications:** This equipment is widely used in metallurgy, chemical industry, cement, building materials, mining, power, refractory materials, mineral processing, and sand making industries. 1. Specific applications include raw coal crushing (including gangue) in coal mines or coal preparation plants, medium and fine crushing of ore, construction waste processing, and the crushing of battery cathode materials.

2. Particle size control: The double-roll crusher can strictly control the output particle size by adjusting the roller gap (usually 1-20mm), making it suitable for applications requiring uniform particle size, such as crushing coke to 10-50mm or finely crushing it to 0-3mm.

3. Features and advantages: The equipment has a compact structure, is easy to maintain, and features low noise, low over-crushing rate, and energy efficiency. Some models adopt a hammerless design or wear-resistant liners, further reducing maintenance costs.

4. It should be noted that double-roll crushers are generally not suitable for high-humidity or sticky materials to avoid clogging the crushing chamber. When selecting a crusher, the specific material characteristics and production requirements (such as feed particle size and output requirements) should be considered.
