The low speed granulators in the ESL 180 Series have been specially developed as low speed grinders for applications in the injection-molding sector. The material to be granulated is fed via a sound-absorbing feed hopper that is available in a range of variations to suit the application. The ESL 180 granulators are mounted on either low or high level baseframes, depending on the application, and they come with suction troughs/bag fill chutes to suit. With these numerous options, the ESL 180 Series low speed granulators can be tailored to an extremely wide range of applications.
The ESL 300 Series granulators are primarily intended for grinding scrap moldings and sprues from the injection and blow molding sector. The ESL 300/400 and ESL 300/800 are especially suitable for larger moldings, such as car door liners, bumpers, or hollow bodies.
Unique Knife Design. Unique knives make adjustment work unnecessary. The curvature of the specially profiled rotor knives ensures a constant cutting circle after re-sharpening, maintaining the cutting gap. Awkward knife adjustments are no longer necessary, and downtime is reduced. The ESL bed knives can be turned 4 times and can also be re-sharpened.
Sturdy Rotor System. The rotor shaft has bearings at each end, and the shaft diameter is designed for the largest rotor width to enable use of a modular assembly across the width range. Staggered rotor blades means that only one blade cuts at once, increasing the cutting torque. All of the machines in this range are therefore suitable for grinding more solid materials and thicker walled sprues.
Quick Snap System. The new quick snap system allows the lower section of the front plate to be easily removed for granulator cleaning. The lower section of the front plate is held in position by two sturdy lever clamps. An electrical limit switch prevents the operation of the machine when this lower front plate is removed. The rotor outboard bearing is mounted in the fixed upper front plate section.
Good Accessibility. The granulators can be safely opened in just a few steps and without the use of tools. The feed hopper is hinged and can be pivoted back. After removing the lower section of the front plate and the suction trough, the machine becomes easily accessible and ready for quick cleaning in case of color or material change.
V-Cut Rotor Design. The V-shaped arrangement of the staggered rotor blades holds pre-cut material in the center of the cutting chamber. This prevents material sticking to the side walls and considerably reduces wear on the grinding chamber walls when processing fiber and glass-reinforced plastics.
