Weighing machine with screw feeder in open bags

A screw weighing batcher is a specialized device that measures bulk materials in automatic or semi - automatic mode. With the help of such equipment, it is possible to ensure the full dispensing of equal portions. A screw dispenser for filling allows you to determine a time or logical sequence - in accordance with the selected principle, substances will be measured by volume or mass.

The advantage lies in the fact that dispensers of this type from ZVO are distinguished by their simplicity of design and increased reliability. By the type of the process, they are all divided into portioned and continuous operations. The latter in automatic mode maintain the proper performance in accordance with the tasks set by the operator. The batch auger batcher periodically feeds the material to be measured into the weighing hopper. Thus, various bulk products are dosed: cereals, soybeans, yeast, bran, flour, cement and other materials.

Features of the operation of the portioned weighing auger batcher

By means of a screw feeder, material is taken from the storage hopper, after which it is transferred to the batcher. If necessary, the auger rotation speed can be changed using a drive consisting of a frequency converter and an asynchronous gear motor. The material is transferred by a stream to the hopper of the auger batcher on strain gauges, from the latter an electrical signal is sent to the controller.

As a result, a continuous correction of the speed of rotation of the screws is carried out, which stop only if the given mass of a specific dose has already been collected, for the purpose of unloading - packing into open bags is considered complete. Each screw feeder includes the following elements: mechanical; electromechanical; electronic. It is their full - fledged interaction that makes it possible to ensure high dosing accuracy.

If necessary, the equipment can always be reset to a different dose, using it in combination with automatic or semi - automatic packaging machines. The screw - type filling batchers from the "Plant of Weighing Equipment" are easily installed under the storage hopper and are characterized by high productivity. Separately, it is worth highlighting the accuracy of filling and a wide range of dose selection. Even if we are talking about the use of semi - automatic equipment, the only operation that has to be carried out manually is to put the bag on the neck of the dispenser.
