Vacuum brick extruder is used for producing a variety of hollow brick which is made of shale, coal gangue, with high fly ash and barren soil of low plasticity raw materials. Extrusion pressure can reach up to 3.0-4.2.  

Vacuum brick making machine adopts upper and lower stage structure, it can be installed in the shape of " 1" or " T" complying with landform.

Complete machine is full steel construction, reducer adopts GB(Chinese standard)1000 and 650 reducer motor. The main part of the brick machine is made of the fierce alloy forging, which extends the life cycle of equipments and reduce repair parts cost. Reamer is adopted wear-resistant materials and spray weld process, it is durable and easy to maintain.

JZK full steel double-stage vacuum brick machine produces all kinds of hollow bricks by using coal gangue, shale, fly ash and clay as the main materials. Its trowel adopts wear-resistant metal powder spraying technology; The upper mixing shaft, trowel and machine body are processed by aging, tempering and quenching; the gear of reductor are hard-toothed surface; clutch adopts screw compression type patent technology, it greatly improves machine working life. The reasonable design and compact structure of our coal gangue brick making machine maks it running smoothly without installing anchor bolt, it greatly reduce the consumption of power which caused by shocking of machine during equipment running. By using this equipment and technology to shift the waste material of value, saving energy and reducing consumption, and will obtain great economical and social benefit.

Features:

Vacuum brick making machine is good at low noise, low power consumption which saving rate is up to 40%, vacuum brick making machine has high automatic level, after setting up the size and strength of bricks, NG products will be returned to raw material storage if brick is not meeting set up requirements, and then go for pressing after mixing, it greatly assure the products' quality.
