<p>The dosing device for introducing measure quantities to a pneumatic transport system comprises a casing (10) provided with a lateral opening (12) fixed to a reservoir under pressure containing the pulverised material. Inside this casing (10) is a fixed tubular casing (14) containing a rotating tubular casing (16). Each of the casings (14,16) are provided with dosing slots (24,26) and diametrically opposite outlet slots (34,36) that provide a direct communication between the lateral opening (12) and a diametrically opposed outlet (32), this communication being more or less reduced by rotation of the rotating tubular casing (16). The transport air under pressure is admitted with the channel (30) by two conduits (38,40).</p> |
