TCJ **0 terracatto facade vacuum extruder is developed based on TCJ**0 clay extruder for extruding wider ceramic board. It break through 3 technical problem of “extruding pressure is not high, clay went hot, poor stability of clay force pressure”, it got national patent on ***0 and have been approved in many terracotta facade panel production lines and ceramic plate ceramic board production lines.

1.TCJ**0 ceramic exturder structure features:

 1.1General structure：

As the drawing 1 shown, TCJ***0 ceramic extruder is conventional up and down 2 grade structure, up part is double shaft mixing device, the *7kw motor through gear box and Coupling drive 2 mixing shaft rotation, installed mixing blades on the front of shaft, installed screw blades on the back of shaft and connect with vacuum room. Installed clay impeditive blade at the last end of shaft, in order to compact the clay and formed a sealed environment with vacuum room before the clay enter vacuum room, and cut the branded thus the clay will not accumulated on the vacuum room and do not make jam happens.

The lower grade use air clutch, *0KW motor through gear box and coupling drove the main shaft and clay board,  lower screw blade use high quality steel making and inlay high grade and easy to changeable wear resistance alloy. Designed high strength organic glass watching hole in the vacuum room with diameter **0mm for easy inspect and clean vacuum room.

1.2 Features:

In the lower part, drive, main shaft, extruding cylinder, extruding funnel and screw blade is designed and special treatment according to wider ceramic board extruding requirement, reinforced main shaft use high quality steel, through quenching and tempering treatment and thermal treatment, enable it enough rigidity and strength. Screw blade as the core parts, is designed based on abroad machines and after repeated experiment according to different material. Complete screw blade is cast forming to guarantee its accuracy.

For easy clean machine and maintenance, clay cylinder jacket and liner adopt splitting structure, cylinder jacket equipped with water cooling system, it can cooling the clay cylinder via cooling water, thus down the clay temperature, liner anti-slip groove use special device, thus can stop the clay revolve and re-back to cylinder.

Extruding funnel (also called machine head) is used to connect the screw blade with mould, for guarantee symmetry, it should according to mould manufacture.

1.3 Other related configuration

Electrical control:electrical cabinet have open Remote control interface, can central controlled with other machines and form automatic production line. Up and down motor use frequency converter regulating speed, it can both single and synchronized regulating speed. Up and down motor rotation speed Synchronization and joint control firstly, can decrease the possibility of clay jam caused by the clay enter and exit vacuum room imbalance.

Temperature and pressure tester: designed digital pressure and temperature tester, it can inspect the forming pressure and clay temperature any time.

Extruding funnel: TCJ**0 extruder equipped with 2 standard funnel **0x**0mm and **0x**0mm, the previous one can produce product with width ******0, the last one use for **0—**0. It can be customized for special requirement.

Mould: Equipped with a **0×*8 hollow ceramic board mould.
