Currently, the existing horizontal dry ball mill discharging method is as follows: a stainless steel sealed cover is installed outside the ball mill barrel to collect the material. The middle section of the ball mill barrel has an opening for feeding and discharging. During milling, a sealing plug is used to block the opening, and the ball mill barrel rotates along the axial direction for grinding; during discharging, the sealing plug is removed and replaced with a plug with a slot hole. The ball mill is started, and the barrel rotates axially. The powdered material is centrifugally ejected from the ball mill barrel through the plug and falls onto the stainless steel sealed cover, eventually discharging from the bottom of the sealed cover. However, due to the external sealed cover on the ball mill barrel, the overall height of the equipment increases, making it inconvenient to add material into the ball mill barrel. Furthermore, because the barrel is enclosed in the sealed cover, it is also very inconvenient to replace the plug. Additionally, the ball mill’s discharge port is located at the middle section of the barrel wall, making it difficult to fully discharge the material, which can lead to contamination or uneven composition.

Our company’s newly developed negative pressure discharge ball mill unit effectively overcomes the shortcomings of the above equipment. It improves the efficiency of both discharging and grinding, is easy to operate, reduces labor intensity, and uses a fan to create negative pressure to extract the powder. The discharge is quick and clean, preventing incomplete discharge or cross-contamination between different product batches.
