What Is The Working Principle of The Powder Filling Machine?
From the perspective of working principle, there are two main metering methods of the powder filling machine, that is volumetric filling and weighing filling.
The volumetric powder packaging machine realizes the filling by controlling the volume of the rotating circles or times of the auger. to be filled. Its advantages are simple structure, no weighing device, low cost, and high filling efficiency.
The disadvantage of the auger powder filling machine is that the filling accuracy varies greatly depending on the stability of the density, the uniformity of the powder size, the hygroscopicity, looseness, and other characteristics of the material.
Therefore, the main application of a volumetric powder filling machine is a powder with uniform powder size, relatively stable bulk density, and with good free-flowing properties.
The powder weighing filling machine is to ensure accuracy by controlling the weight of the material to be filled. Compared with the auger powder filling machine, its structure is more complicated, the machine cost is higher, and the filling efficiency is lower than that of volumetric filling.
It's well suitable to fill powder with uneven powder-particle size, unstable bulk density, and with high value. In order to improve the filling accuracy and feeding speed, the weighing and filling processes are at the same time.
For the gravimetric powder filling machine, the target weight is filled with a high-precision load cell, and the auger is mainly used for unloading.
Powder filling machines with two working principles are widely used in daily chemical, food, pharmaceutical, and other industries. The user can choose according to various factors such as budget, powder characteristics, and packaging weight.
