2. The device for proportioning loose materials with a worm weight feeder contains a weight feeder with a mobile element of the feed mechanism in the form of a worm, which moves loose material. It also contains a device for filling the hopper of the feeder. The hopper is suspended on the weighing system, preferably a tensometric system. Its output signal is processed in the control system. The latter has an analogue-to-digital converter at its input. The output of the converter is connected to the digital programmable control block of the driving engine of the mobile feed-mechanism element. Characterized in that: The rotation axis of the worm (2) of the feed mechanism (1) is at an acute angle, upwards in the direction of the loose material transport, with respect to the reception level of loose material, preferably at the angle equal to the dumping angle of the proportioned loose substance. The worm is coupled with the driving engine, preferably at the side of the feed mechanism (1) outlet.
