Double class vacuum extruder
1. The top ten enterprise. National free-inspection products and famous brand.
2. Which can produce hollow brick, multi-hole brick, heat preservation block, , solid brick.
3. Material: Clay, shale, coal gangue, fly ash etc.
4. Characteristic of brick: Energy-saving, discharge-reduing, heat weight-saving.
5. Advanced level at home and broad
6. Highly extruding pressure, quick molding. The green adobe is strong, solid and smooth
7. Double-stage vacuum extruder

This machine adopts the design of the strong combine, the principal axis bearings of the extrusion system are connected for integral whole, guaranteeing united at heart degree in principal axis and benefiting in validly evenly extruding. Thus the extruding pressure is big and anticipate to compress in advance and guarantee high vacuum degree, making unburunt brick more dense and solid. It is applicable to making all kinds of hollow brick of coal of coal stone, shale. Powder coal ash and clay raw material. The parameter is subjet to change for different raw materials.
