JKR45/45-20 TWO STAGE VACUUM EXTRUDER is clay brick making machine.This machine is developed for many solid brick factories developing into hollow brick factories. Compared with JZK model vacuum machine, it saves investment by 30%, improves production output by 20%, and saves energy by 30%. Soil etc raw material cleans in the vacuum room, and goes into the consigning room, then extrudes them by the next stage reamer. When the mouth of machine adopts the different types of moulds can produce different kinds of hollow bricks. The machine is particularly designed, compact and can save soil, energy as well as benefits from the waste, besides that, economy recovery period is short. It is an ideal machine for factories change into hollow brick production.
