Some powder materials, such as battery cathode/anode materials, potassium perchlorate, cobalt tetroxide, graphite powder, and matting agents, are highly buoyant and contain significant trapped gas. This makes them difficult to pack into bags or drums; forced packing leads to bag expansion or breakage. Many companies resort to prolonged settling, which is time-consuming and inefficient. The JKF-159CE vacuum deaeration valve bag packer and JKF-159H twin-screw extrusion deaeration packer offer solutions. The JKF-159CE effectively handles high-gas, low-density ultrafine powders with zero dust emission and high compression filling. The JKF-159H features twin-screw feeding, automatic weighing, adjustable parameters, large/medium/small feed modes for speed and accuracy, enclosed dust-proof structure, and gas expulsion before filling. Guangzhou Jingke Packaging Equipment Co., Ltd. has developed these advanced deaeration packers that remove air from powders without altering properties, solving dust, bag expansion, and breakage issues while boosting efficiency.
