Screw conveyer
Serie 30
Identification – SD
Type of construction – trough, welded
CHARACTERISTICS AND APPLICATION:
Screw conveyer is intended for a fluent transport of powedered and grained materials with graine size 0-30 mm in usual granulometric structure of milled products. The moisture content of powdered materials must be lower than 1% water and the material must not be adhesive. If the material contains clay, so the allowable moisture content is max. 3% water. The max. allowable temperature of conveied material is between -30 and +150 ° Celsia. The transport is horizontal, only in any case - if it is necessary - the possible and allowable inclination angle is max. 10 degree and the application must be before consulted with producer.
DIMENSIONS AND PARAMETERS:
Type range of srew conveyers contains 9 basic sizes derived from helix diameter < 135 up to 800 mm >, in the whole scale of screw shaft rotation speed and corresponding capacity. Transport length can be chosen between 1.000 – 30.000 mm.
The conveyers are delivered completely equiped, with drive, rotation indicator, incl. connecting material. After technical – commercial consulting it is possible to order some modifications or a special type of construction.
DESCRIPTION OF CONSTRUCTION:
Screw conveyer consists of trough, which is shut on both ends (sites) with shields. Parts of these shields are ball bearings with special packings of worm shaft, too. The trough has a removable coverings with revision openings. The worm shaft is positioned on bearings outside of trough. At longer conveyers are used an adjustable hanging bearings. Inlet and outlet flange are delivered extra to be welded on the building site or are welded already at the assembly in workshop. The drive of screw conveyer is made in a few ways: a standard construction with gear box, which is via elastic clutch connected with screw shaft, further alternatives are chain gear or slip-on gear box.
Construction – screw conveyer is made from a normal steel (class 11 acc. CZ-Standard ČSN) as a welded construction. Screw windings are pressed singly and are made from a normal/carbon steel (class 11 acc. CZ-Standard ČSN). On special requirement the windings can be made from material HARDOX or with hard surfacing (welded-on).
A special type of construction and special requirements must be consulted with supplier !!!
