This machine is composed of three parts  the upper part, the lower part and the de-airing system .The former two parts utilize worm extruding Raw clay compacted by the upper part of this extruder goes through the vacuum chamber and is evacuated of air by the vacuum pump and then extruded into clay column with specified cross-section by its lower part. Because the raw clay in this extruder has under gone two extruding processes and de-airing treatment．the products of top-quality with compact composition．High compressive and shearing strength can be obtained Thus．this is an ideal equipment for making thin—walled hollow wares and solid bricks. This machine is suitable for making bricks from clay(with water content 18-2％). Shale coal gangue and fly ash(mixed with clay) as its raw material And only by this extruder can sandy loam(plasticity Index 7-10)or slit from rivers and lakes, which cannot be shaped by ordinary extruders. Be made into standardized green brick.
