JKF-159 model CH valve pocket powder quantitative packaging machine USES frequency conversion speed adjustment, electronic automatic measurement technology, by PLC program control, can completely solve the super fine powder filling a complete, accurate measurement with, no dust etc. Characteristics. Variable speed by screw conveying, divided into the spiral and half a spiral, the spiral can be directly into bags in materials, mainly for the proportion of big, material liquidity and poor, material more viscous material design, such as: white, wet sour zirconium, mica powder, precipitation barium, small particles powder, dry mortar, add seam an agent, etc. Half a spiral of the spiral plus auxiliary air frequency materials into bags in indirect, mainly for 325 mesh-2500 mesh liquidity is good, not easy jam material design, such as: calcium carbonate, heavier barite ore, quartz powder, starch, zinc stearate calcium magnesium, stabilizer, la powder, pigments, magnesium hydroxide aluminum, etc.
