PCT No. PCT/FR86/00211 Sec. 371 Date Feb. 6, 1987 Sec. 102(e) Date Feb. 6, 1987 PCT Filed Jun. 19, 1986 PCT Pub. No. WO86/07629 PCT Pub. Date Dec. 31, 1986.Apparatus making it possible to effect accurately in line and continuously the weight feeding of granulated or pulverulent products. It comprises two separated endless belts for extraction and dispensing. The endless belt of the dispenser is continuously weighed as a whole and the speed of the extraction apparatus is controlled to the measurement of the instantaneous load of product distributed on the dispenser belt. It comprises: a hopper (2) for storing the product to be weighed under which is arranged an endless belt 3 for extraction of which one of the two support drums (5A, 5B) is driven at a variable speed by a motor-reduction gear, a dispenser unit disposed below and in line with the endless belt 3 of the extractor, this unit being constituted of, a fixed T-shaped support frame (9) which is provided at its ends with three pillars (10A-10B-10C) supporting three strain gauge type flexion weight indicators (11A-11B-11C) which are provided with flexible suspension cables (12A-12B-12C) to which is suspended an ultralight tubular frame (13) and, an endless belt of which drums 14A-14B are supported by said frame 13, one of the drum 14A being driven at variable speed by a motor-reduction gear unit (16). an electronic control chain F1-F2 between the motor-reductor gear unit (16) driving the endless belt (15) of the dispenser and the endless belt of the extractor (3) said chain being such that the speed of the endless belt of the extractor (3) is controlled in dependence to the measurement of the instantaneous load of product distributed on the dispenser belt (15). Application to the fertilizer industry.
