Double Stage Vacuum Extruders are designed for extrusion of bricks at medium or high capacity.
The raw material is mixed to a fairly stiff texture and is then loaded into an extruder where a worm screw pushes it along a barrel into a vacuum chamber which compresses it through a taper and out through a die.
The die is machined to a precise size and shape larger than the finished size of the brick, calculating how much the raw material will shrink during the drying and firing process. The raw material emerges as a continuous brick shape column.
1.Designed to work with clay, flyash, shale or coal gangue, for production of extrusion of bricks.
2.Especially suited to manufacture of high class bricks.
3.Four models available according to raw material and end product requirement.
