Single-screw extruder KE series

grooved feed

Main Extruders The main principle of the SKETmatik extruders is that they are manufactured to strict design principles and quality control to meet our customer’s requirements Barrel & Screw are available with L/d ratios from 25 to 35. The screws are nitrided as standard The barrels are air cooled with water-cooling to the feed zone. The options of grooved feed zones with axial or spiral grooves are also available. Screws can be supplied with any geometry to meet specific requirements including: Barrier screws that can be combined with shearing and/or mixing zones The screws can be removed from the barrel either forwards or backwards Bi-metallic cylinders are available for use with abrasive materials. Screws in special material are also available Drive As standard motor and gearbox are mounted in a U configuration and the motor is AC with a digital controller (flux vector). Alternative drive systems are available: Compact Geared Motor, Torque Motor Both of these systems have the advantage of taking minimal space, having low noise levels, and are environmentally clean being water-cooled. The AC digital controller can also be water cooled if required. Barrel Temperature Control Efficient barrel temperature control is achieved using ceramic or glimmer heater bands and cooling fans blowing over specially designed copper cooling fins to improve cooling efficiency Hopper: The hopper can easily be moved between three positions: OPEN; CLOSED and DISCHARGE.Hoppers with sight windows or level monitoring systems are also available.Pneumatic or other material handling systems can also be accommodated.
