The pellet crumbler can produce smaller pellets that are more uniform and have a lower powdering rate compared to those directly pressed using small-aperture ring dies. Its core is a pair of rolls with specific corrugations. By precisely adjusting the gap between the two rolls, the particle size distribution of the crushed product can be controlled. Compared to direct pelleting with small-aperture dies, the crumbling process offers higher output, lower energy consumption, and less die wear. The equipment runs smoothly, crushes efficiently, produces little powder, and well meets the feeding needs of young animals like chicks and piglets for small pellet feed.
Specifications are usually defined by the diameter and length of the rolls. Power configuration ranges from 7.5kW to 55kW. The processing capacity matches the supporting pellet mill's output, ranging from 2 to 15 tons per hour. The roll speed is precisely calculated to ensure crushing is primarily by shearing force rather than compression. The roll gap adjustment mechanism is sensitive and precise, allowing for micron-level adjustments. The equipment inlet has a feeding device to ensure even entry of pellets into the crushing zone.
Mainly used in feed production for poultry (especially for broilers and layers during the brooding and growing phases) and pigs (weaned piglets), producing crumbles with diameters between 1.0mm and 2.5mm. This form of feed is easier for young animals to eat, improving feed palatability and utilization. It is an important piece of equipment in specialized, phase-feeding feed mills.
