<p>The equipment has a metering sieve in the base of a chamber, and a rotary metering brush working with the sieve. The chamber itself, base (2), and frame (4) of the sieve (5) are all shaped to match the radius (13) of the metering brush (2), and the base is movable up and down. The brush bristles (15) work against the sieve at a steep angle. The chamber (1) can be tapered at the bottom, the latter having wedge-shaped components matching the brush radius where it joins the sieve.</p> |
