Feed pellet mills are machines that make small pellets from soft, flat materials. They make pellets that are easy to feed by converting the ingredients into a tasty treat that animals love. So, here are some tips for better use of feed pellet mills. We'll discuss how to select the right ingredients, maintain equipment sanitation, adjust mill settings to ensure you get the desired quality, and make sure to store ingredients in a way that protects their integrity.
Optimizing the raw material handling process
The characteristics of the raw material and the way it is pre-treated have a significant impact on the efficiency of the ring die pellet mill. Firstly, it is important to control the moisture content of the feedstock. Ideally, the moisture content of the raw material should be kept between 10% and 15%. If the moisture content is too high, the material in the ring die is easy to form a blockage, which not only reduces the production efficiency, but also may lead to a decline in the quality of the particles, softening, deformation and other problems; too low a moisture content will make it difficult to mold the material, increase the energy consumption of the equipment, also affecting the production efficiency.
Secondly, the uniformity of raw material particle size should not be ignored. Too coarse raw materials are difficult to pass through the ring die die holes, which will cause equipment idling, wear and tear; too fine raw materials may lead to excessive fluidity of materials, in the pressing process can not form an effective pressure, affecting the particle molding. Therefore, before the raw material enters the ring die pellet machine, it needs to go through strict crushing and screening process to ensure that the particle size of the raw material meets the requirements of the equipment.
Reasonable adjustment of equipment parameters
Firstly,Many equipment parameters of the ring die pellet mill, such as the rotational speed of the ring die, the gap between the pressure roller and the ring die, and the selection of die holes, etc., are closely related to the production efficiency. The rotational speed of the ring die is not the higher the better, although the higher rotational speed can improve the output to a certain extent, but more than the optimal rotational speed range of the equipment, it will make the material in the ring die residence time is too short, can not be fully extruded and shaped, resulting in a decline in the quality of the particles, and at the same time will accelerate the wear and tear of the equipment.
Secondly,The gap between the pressure roller and the ring die directly affects the extrusion effect of the material. Too large a gap, the material can not be subject to sufficient pressure, difficult to shape, resulting in lower production; gap is too small, the pressure roller and the ring die friction between the increase, not only increase the energy consumption of the equipment, but also make the ring die and the pressure roller wear and tear, shorten the service life of the equipment. Usually, the gap between the pressure roller and the ring die should be adjusted to 0.1-0.3 mm, the enterprise can be in the process of equipment operation, through the observation of the molding of the material and the sound of the equipment, the gap is fine-tuned at the right time.
Thirdly,The choice of mold hole is also crucial. Different materials and product specifications require different hole diameters and depths. Mold hole aperture is too small, the material through the difficult, low yield; aperture is too large, can not meet the requirements of the product particle size. The ratio of the depth of the mold hole to the diameter of the hole (depth-to-diameter ratio) also affects the efficiency of granulation, the depth-to-diameter ratio is too large, the resistance of the material extrusion increases, and the productivity decreases. Therefore, enterprises should be based on the actual production needs, choose the appropriate aperture and depth ratio of the ring die, such as the production of livestock and poultry feed, you can choose the aperture between 2-8 mm ring die, and reasonable control of the depth ratio.
Enhance the maintenance and repair of equipment
Regular and standardized equipment maintenance is the basis for guaranteeing the efficient operation of the ring die pellet machine. In the daily maintenance, we should clean up the residual materials inside the equipment in time to prevent the materials from accumulating and drying on the ring die, pressure roller and other parts, which will affect the normal operation of the equipment. Especially when replacing the production of different raw materials, it is more important to thoroughly clean the equipment to avoid cross-contamination of raw materials and ensure product quality.
Regularly check the ring die and pressure roller wear is also extremely important. Ring die and pressure roller are the core wear parts of ring die pellet mill, and their wear degree directly affects the production efficiency and pellet quality of the equipment. When the ring die and pressure roller are worn out, the extrusion effect of the material becomes worse, the pellet molding rate decreases, and the output decreases. Once the ring die and pressure roller are found to be seriously worn, they should be repaired or replaced in time.
