Feed mill filter coarse filtration unit: the front-end core barrier to ensure pure production

The multi-stage filtration system of the feed mill filter is the core defense line to ensure purity. As the first checkpoint of the system, the coarse filter unit eliminates potential threats from the source with its efficient interception ability of large particle impurities, laying the foundation for the stable operation of subsequent production links and the improvement of feed quality. Its unique design and function make it an indispensable key link in the feed production process.
The efficient operation of the coarse filter unit depends on carefully selected filter media. Commonly used wire mesh and woven filter cloth are specially designed in terms of material and structure. The wire mesh is mostly made of stainless steel, which not only has excellent corrosion resistance and can adapt to the erosion of acid and alkali substances that may exist in the feed production environment, but also has high strength and good toughness. The uniform large-aperture grid structure formed by the precision weaving process enables it to withstand the impact of hard foreign objects such as stones and metal debris without easy damage, ensuring a stable interception effect during long-term use. The woven filter cloth uses high-strength fibers and is woven into a filter layer with a specific porosity through special textile technology.
In the feed production process, if large particles of impurities are not intercepted by the coarse filter unit, a series of serious problems will occur. When hard foreign matter such as stones enter the grinder, they will collide violently with the high-speed rotating blades, accelerate the wear of the blades, and may even cause the blades to crack, causing equipment failure and shutdown, which not only delays the production progress, but also greatly increases the maintenance cost. Once metal debris is mixed into the feed, it will not only contaminate the product, but also may damage the digestive tract of farmed animals and affect the health of the animals. Soft foreign matter such as hemp ropes and plastic sheets are easy to entangle in the transmission parts of mixers and granulators, causing equipment to operate poorly or even shut down due to excessive load. The coarse filter unit isolates these hidden dangers by setting up a solid barrier at the front end of production, ensuring that core equipment such as grinders and mixers can operate stably in an environment without interference from foreign matter, thereby ensuring the continuity and efficiency of feed production.
Pure raw materials are the prerequisite for producing high-quality feed. The presence of large particles of impurities will seriously affect the nutritional balance and palatability of the feed. Foreign objects such as stones and metals not only destroy the physical structure of the feed, but may also introduce harmful ingredients and reduce product safety; soft foreign objects such as hemp ropes and plastic sheets will cause uneven mixing of the feed, making it impossible to accurately proportion the nutrients, affecting the feeding effect of the feed. The coarse filter unit efficiently intercepts various large particles of impurities to ensure that the purity of the raw materials entering the subsequent production links meets the standards, providing reliable guarantees for precise formula mixing, granulation and other processes, and improving the quality and market competitiveness of feed products from the source.
