Screw conveyor overview:
Without shaft screw conveyor is a new conveyor equipment, its R&D base on the advanced technologies both at home and abroad.
The helicoid of Screw conveyor is thick belt blade, through the driver to drive, don't set oart.
USES:
Without shaft screw conveyor applies to transport adhesion strong, paste sticky materials(such as the sewage treatment sludge),the high moisture content and waste materials (such as living garbage around).
Classification:
Our factory production-without shaft screw conveyor divide into “O”and “U” two types.
“U” without shaft screw conveyor it’s case for U, apply level transport and also open feed.
“O” without shaft screw conveyor it’s case is round, can tilt or level transport, the angle is no more than 15 °.
“O” without shaft screw conveyor divide into general type and explosion-proof, explosion-proof is suitable for chemical systems’use. With airtight, isolation and nitrogen etc. Its out and in size designed according to chemical standard HG2059-20635- 97.                                               Screw conveyor technical parameters:
