Description
The CERAMATIC brick press with a fixed output rate is an all-mechanical automatic machine with a 3-station rotating table, comprising a filling station, a moulding station and a de-moulding station. The entire cycle of pressing, ejecting and fuming the table is operated by motor power through an electrical motor, diesel or petrol engine. The bricks are pressed at high compaction pressures through a mechanical lever system. The production rate can be determined in advance through the choice of a larger or smaller fly-wheel Fitted on a robust base frame with four wheels, the CERAMATIC can easily be moved from site to site.
Moulds for special brick sizes are available on request. Alternative to the standard CERAMATIC press, a hydraulic version exists, Type H. which produces bricks of greater heights at even higher compaction pressures.
Operating the CERAMATIC
Once the machine is in operation the moulds at the filling station are constantly filled by a worker using a shovel. The rotating table turns every 2 to 3 seconds so no pauses are necessary. The over-filled moulds pass under a cone-shaped roller, which removes the excessive soil and pre-compacts the contents of the moulds.
When the compressed bricks are ejected at the de-moulding station, a worker immediately removes the bricks and places them on a wheelbarrow, which is then taken to the drying area.
Additional Equipment
CERADES H2 soil disintegrator, comprising 2 counterrotating hollow drums driven by an electrical or diesel motor, specially developed for use with the manual and automatic presses.
