Hollow brick machine  designed reasonable and compacted, it can work steadily without foundation bolts, so it is easier in installation. The steel material of shafts and gears are adopt high quality carbon steel and alloy steel,the key parts are quenched and tempered treated so as to extend the life. Augers are adopt wear- resistance metal spray painting treatment.

 
All machinery adopted spiral pressure clutch (patent) which have high sensitivity and declutching thoroughly. The de-airing extruders use electric clutch to make operation more convenient, The de-airing extruder adopt copper bracket bearing and immerging lubrication method. Reducers adopt hardened face gears .Zhengtai machinery  not only provide vacuum brick but also provide the professional consultation from the beginning of project till the after-sales service.

 
1.It's the latest all steel double level vacuum extruder. In design and development of it, we    absorbed the advanced the advanced

technology of congener productions from home and abroad, and use the advantages of various models for reference.

2. It has rational configuration, excellent applicability and high efficiency.

3. It's sturdy and durable. It's convenient to fix and maintain.
4. It can be remote controlled. No doubt, this machine is ideal brick manufacture equipment for using materials of clunch, shale, coal gangue.
