Stainless steel: conforming to the GMP and food health authentication, suitable for packaging the corrosion resistance chemical products. PLC touch screen and man-machine interface: PLC works stably, antijamming, high weighing precision, convenient and easy operation; Weighing feedback proportion track type, overcoming the shortcoming of changes of packaging weight caused by the changes of material proportion. Servo motor-driven: high precision location, strong torque, long life, adjustable rotational speed. Speed reducer: low noise, long life and lifelong maintenance. Packaging weight adjustable at any time, operating condition changeable as necessary, convenient operation Adjustment parameter of each kind of product can be stored for later use but not more than ten. The entire seal air damping glass and stainless steel hopper, clear sound of the material, no dust releasing, with dust exhaust apparatus at the mouth of filling, keeping the workshop clean. Can adapt the ultra fine dust to the big pellet and so on the many kinds of materials by replacing the screw attachment. machine Parameter: Metering mode: Screw rotation filling traced by weighing feedback Packaging weight: 10-5000g(screw attachment changeable) Weighing range: 1-6000g(Resolution 1g) Packaging precision: Packaging weight: ≥100g with an error ≤0.5-1g Packaging weight: 100-1000g with an error ≤0.5%-1% Packaging weight: ＞1000g with an error ≤0.25%-0.5% Packaging rate: 10-50bags/min Power supply: Three-phase 380V(or single phase 220V)50-60Hz Total power: 1.8KW Weight: 260kg Dimensions: 800×1200×2050mm Hopper volume: 50L
