Vacuum Extrusion

JW – JK 45/45

Main characteristic of the Vacuum Extrusion

The JZK series Vacuum Extrusion Clay Brick Machines produced by Golden Bay Company area whole steel structure, double – stage vacuum brick machine, they are energy – efficiency vacuum brick machines and are the the main molding equipment to produce hollow coal gangue brcks.

To produce bricks, the main machine makes the upper half and the lower parts connect together hermetically; the mixed brick  raw materials are squeezed out for the first time by preceding squeeze procedure, then squeeze fine materials go into the vacuum chamber, the air was extracted from the raw materials, like clay; then the materials are squeezed out again by the lower helix machine, then they turn to clay bras with smooth surface and high density.

Theses vacuum Extrusion Clay Brick Machines  are made of selected high-quality steel plate in welded construction. All of the major parts are produced through thermal refining, which are compact and functional. Get stable operation, and energy – saving and with low power consumption. They are the main products applied to small brick factories or power – lacking areas.

Advantages of machine

1.      The machine is mainly made of wear – resistant cast steel; it is hard and durable, and specialized in producing hollow shale bricks and hollow coal gangue bricks.

2.      The bearing pedestal is huge and 75 KGS in weight. It is also made of wear – resistant cast steel.

3.      The charging hopper of the main machine is board and with splits design and also made of made of moulded steel. It takes 30 minutes to replace an upper helix machine.

4.      The manual bearing oil supply system can make sure that the bearings are always working under lubricating condition.
