The air chute conveyor is suitable for conveying various dry powder materials such as cement and raw materials. Due to its small wear, easy maintenance, low power consumption, material saving, no noise, good sealing, safety and reliability, it is widely used in large, medium and small enterprises. When conveying powder materials such as cement and raw materials, iron impurities are often mixed in the production process. If these iron impurities are not removed, it is easy to cause the produced materials to contain a large amount of iron impurities, affecting the quality of the finished products.
