<p>The transporter has a cylindrical tank (1) with a conical base (2). There is a hopper (3) at the top, acting also as a dosing device. A pneumatic device controls a claw (7) which reciprocates vertically within the lower part of the hopper. A compression chamber (8) fluidises and moves sand and mortar pneumatically. A valve (11) gives total decompression of the equipment and is placed in front of a trap door (4). The sand and mortar leaves the compression chamber via a spout (9) and flows into a pipe (13).</p> |
