·The type of screw depends on the application manufactures a "Core Buster" design hollow pipe only for small amounts of heat transfer as well as complete hollow flight screws when larger amounts of heat transfer are required Heat Transfer Screws are constructed of mild steel standard 300 series Stainless Steel 304SS or 316SS or heat
·Heat Transfer Screw Conveyor Hollow Flight Design Our heating and cooling screw conveyors indirectly transfer heat to or from the product by introducing a heat transfer medium such as cool water hot oil or steam through a special trough jacket and/or the pipe and hollow flights of the screw conveyor Achieving the
·Screw Heat Exchanger We provide unique solutions for each specific field of application and cover the entire process portfolio including cooling off bulk solids such as bed ashes drying of sludges or pastures and heating off such as petcoke for the anode lines of the aluminium industry among other applications Our screw heat exchangers vary substantially
Screw conveyors with conventional design only allow the heating or cooling medium to flow through the housing and optionally the worm shaft where as the hollow screw flights of our KÖLLEMANN screw heat exhanger are used for heat or cooling transfer by means of a thermal medium along the entire length of the screw With the active use of the
3 ·Hollow flights are used to pass heating or cooling liquids around the helix Typically both the hollow centre pipe and the hollow flight are used as a heat exchanger to cool heat or thaw the material being conveyed Short Pitch Flight Short pitch screws are used in inclined conveyors They are also used to control the feed at the inlet
Table of Contents Download Guide PDF Standard Pitch Single Flight Standard pitch single flight screws have the outside diameter equal to the pitch and are the most common screw type used for horizontal screw conveyors and inclines up to 10 degrees Variable Pitch Single Flight Variable pitch single flight screws have […]
5 ·Our heat transfer conveyors have special designs of flights and paddles that homogenise the material as it is conveyed thus giving better heat transfer and a more even distribution of heat The capacities of the conveyors depend on the heat transfer characteristics of the product and the difference between the required output temperature of the
·Cooling Screw Conveyor or Screw cooler Due to their design our screw heat exchangers differ from the standard models available on the market mainly due to the proven and tested hollow flight principle which combines several advantages The most outstanding advantage is the achievable power density compared to energy transfer via shaft tube and
