Roller crusher is the key equipment for efficient grain crushing and protection

In the grain processing scenario, roller crusher is a key equipment: grain processing plants use it to crush whole wheat and corn into uniform wheat kernels/corn grits for subsequent flour making or food processing;

Family workshops or small processing points adjust the roller gap (1-5mm) to control the crushed grain ratio, retain complete rice grains/wheat kernels, and improve the quality of finished grains (such as freshly milled rice and coarsely ground corn flour);

Feed mills use it to pre-process rice, soybean meal and other grains. After crushing, the material is easier to mix with other raw materials to improve the palatability of feed. From primary processing to fine processing, it is a “core tool” to improve the utilization rate of grains and the value of finished products.

Conventional Crushing Equipment vs. Máy nghiền con lăn

Traditional crushing equipment: single or double rollers have uncontrollable strength, and there are many grains with low integrity (<85%) after crushing. There are many dead corners in the silo, which takes time to clean (more than 15 minutes). The parameters need to be adjusted repeatedly when changing materials. It is easy to crush unevenly when adapting to raw materials of different hardness such as hard wheat and soft rice.

Roller crusher: double rollers + adjustable roller gap (1-5mm), particle integrity ≥95% after crushing, no dead corner silo + side opening quick-release door to clean residual materials in 5 minutes, variable frequency speed regulation to adapt to different hardness such as hard wheat and soft rice, high crushing uniformity, reducing the loss of fragments from the root, and improving the quality and efficiency of grain processing.

Roller Crusher Working Principle

ACME roller crusher uses a double roller structure, which is very practical when working. As soon as the material falls from the feed port to the middle of the two rollers, the motor drives the double rollers to rotate to the middle, and the wheat, corn and other grains are gently crushed by the extrusion force of the roller surface.

The surface of the roller is either covered with food-grade polyurethane coating or polished with high manganese steel, which is clean when in contact with the grain, and there is no need to worry about metal contamination. The gap between the two rollers can be accurately controlled by the adjustment device, which can be adjusted from 1 mm to 5 mm. The crushed particles are particularly regular and the integrity can be guaranteed to be above 95%.

The silo is designed without any dead corners, and the two rollers are driven independently, so the material is particularly evenly stressed, and the crushing is fast and stable. The processed grains are finally discharged smoothly from the bottom, and the precise initial crushing of grains is easily completed.

Material falls from the feed port into the space between the two rollers, where it is squeezed and crushed, and the final product falls out naturally. For extremely hard or unbreakable materials, the roller crusher’s rollers can automatically yield using hydraulic cylinders or springs, increasing the gap between the two rollers. This allows the material to fall out.

Thus protecting the machine from damage. A gap exists between the two rollers, rotating in opposite directions. Changing this gap controls the maximum output particle size. A double-roll crusher uses a pair of rollers rotating in opposite directions to crush material, while a quadruple-roll crusher uses two pairs of these rollers.

What scenarios can the roll crusher be extended to?

In addition to the primary processing of grains, roller crushers can also be extended to multiple scenarios:

Chinese medicine factories crush Chinese wolfberry, astragalus and other medicinal materials (retain medicinal particles and avoid metal pollution); nut factories process walnuts and almonds (adjust the roller gap to achieve shell-kernel separation or uniform crushing);

feed factories pre-process bran and soybean meal (easier to mix after crushing, improving feed palatability); grain deep processing companies make grain powder/meal replacement powder (precisely control the crushing particle size to reduce subsequent grinding energy consumption).

Its characteristics of grain protection, uniformity and easy cleaning are adapted to the dual needs of “quality + efficiency” in many industries.
