Duplex single-worm vacuum refiner 1000-3000kg

Duplex single-worm vacuum refinerThis refiner will be in conformity with CE, and its control to CS standard.Barrels are from seamless stainless steel tube. That makes the barrel more strong, high concentricity, creating higher extruding pressure. The worm is with changing pitch and changing-depth, and is welded from stainless steel 304. The worm is high in strength, light in weight. The clearance between worm and barrel is 0.75 mm max. measured at one side of the worm. High-precision, i.e., Class 6, gears with case-hardened and ground teeth are for gear reducers. The worm supporting bush is from nylon LPO, Germany. The bush is self-lubricating, wear-resist, and can work under high pressure. All metallic parts in contact with soap are in stainless steel 304. The property class of all carbon steel threaded fasteners will be over 8.8, and with locking devices. When the threaded fasteners are made from stainless steel the strength of material will not be lower than that of A270. Pneumatic clutches for upper and lower extruders are supplied by Eton, USA. Level probe inside the vacuum chamber is to control the start/stop of the upper extruder. Switches and other electric components are supplied by Schneider, France. Frequency adjustable A.C. drive for lower extruder is supplied by Allen-Bradley, USA. Operation panel is supplied by Rittal, Germany. Touch screen by EM, Taiwan. PLC by Allen Bradley, USA.
