Double roll crusher is suitable for fine crushing operations with a feed particle size of less than 80mm and a finished product size requirement of 50 mesh - 20mm, such as the use of cobblestones, construction waste for artificial sand production. Mining crushing for iron ore, quartz stone.Crushing raw materials for the ceramic industry. Coarse and medium-sized crushing for brittle block material. And its feeding granularity is large, and the discharge particle size is adjustable, which can crush the materials with compressive strength ≤ 160 MPa. Especially in the coal industry, the use of this machine to crush the raw coal, as long as the iron removal, impurity removal, no need to remove the waste rock, can be directly broken, broken material, uniform particle size, low fragmentation rate, thereby simplifying the coal preparation process, reduce investment and production costs.
Know more about FDM Double roll crusher
1. Low noise, reliable performance
Double roll crusher crushing capacity is strong, stable and reliable in performance, can reduce noise pollution, and has the effect of environmental protection.
2. High production efficiency and large throughput
The broken product has a cube-like shape, low needle-like content, no internal cracks, fine particle size, and improved production quality and efficiency.
3. Long life for wearing parts and low loss
Roller wear cycle is long, wear parts adopt the latest high wear-resistant materials, can break high hardness materials, low loss, long service life, can bring considerable economic benefits for customers.
Double roll crusher is mainly composed of roller, roller support bearing, pressing device, adjusting device and drive device.
A wedge-shaped or gasket adjusting device is arranged between the two rollers. The top of the wedge device is equipped with an adjusting bolt. When the adjusting bolt lifts the wedge upward, the wedge moves the movable roller away from the fixed wheel, that is, the gap between the two rollers. As the size of the material increases, the particle size becomes larger. When the wedge moves downward, the two-wheel gap becomes smaller and the particle size becomes smaller when the movable roller is pressed by the spring. The gasket device adjusts the size of the material by increasing or decreasing the number or thickness of the gasket. When the gasket is increased, the gap between the two rollers becomes larger. When the gasket is reduced, the gap between the two rollers becomes smaller and the particle size of the discharge becomes smaller. . The drive mechanism is composed of two motors, which drive the drag roller through the V-belt drive to the sheave, and rotate in the opposite direction. When the material is crushed, the material passes through the roller from the feed port and is broken by rolling. The broken product is discharged from under the bottom frame.
