TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The granulator further comprises the sludge hopper feed screw connected to a sludge extrusion chamber. The sludge extrusion chamber is equipped with screw extrusion surface of the hollow shaft. The hollow shaft of the inner cavity constitutes a clinker chamber, where the clinker chamber and clinker silo are connected. The clinker chamber at its inner concentric is provided with a spiral blade within clinker extrusion axis. The clinker chamber and sludge extrusion chamber are connected to granulated sludge chamber. The granulated sludge chamber at bottom outside parallel to the axis has a first cam and a second cam. The first cam and second cam is tangent to the circumference of the cam and turn in the opposite vertex and the sludge is used for extrusion molding. he urban sewage sludge compost automation device comprises compost barrel equipped with a removable liner, where the liner contains multiple separators. The separators are adhered using a binder. The sawdust and hollow glass beads are bonded and extruded and the inner part of the hollow glass beads are filled with a sponge and vermiculite. The cutting machine further comprises feeding system, separator feeding system, and material feeding system. In the urban sewage sludge compost automation device a first electric door is provided between the first fermentation section and the second fermentation unit and second electric gate is provided between second fermentation unit (502) and finished part. The fermentation bin further comprises a leachate collection system, dehumidification system, feeding system, ventilation system, humidification system, and temperature control system. The first cam and the second cam is provided to a side next to the granulator and further comprises sludge stop feeding mechanism comprising back gauge tabs, where the tabs are fixed to the spring seat, and the spring seat is fixed to the granulator. The materials include vermiculite, diatomaceous earth, zeolite, sand, limestone, or red shale.
