Technical features：

1. This machine is made of all steel and is driven in two stages: upper and lower. The main shaft of the extrusion is connected to the mud cylinder as a whole, ensuring the concentricity of the main shaft and no swinging phenomenon.
2. This machine uses coal gangue, shale, and clay raw materials, and has a one-time code burning production process, which can produce load-bearing bricks and porous bricks.
3. The use of tungsten carbide spray coating on the mixing teeth of the cutter extends its service life.
4. Adopting advanced sealing technology, high vacuum degree, high extrusion pressure, and strong production capacity.
