Rolling mills as stand-alone machines for processing of plastics as granulate, powder or for plastification and blending of rubber or raw rubber or natural rubber: Laboratory rolling mills as stand-alone rolling mills are used for the process of blending or plastification of test materials, focused on process quantities above 500 g The rolls of such laboratory rolling mills will rotate against each other and this with a specific and continuously adjustable speed/friction. Stand-alone rolling mills of our make of this category have a roll diameter above 150 mm. A table structure will not be required. Our stand-alone rolling mills can be equipped with rolls running in parallel or also with faster running roll in front/at the rear On request, the rolls can be heated. Heating but also cooling of the rolls may take place e.g. by peripheral heating ducts. At processing of rubber, mostly a cooling of the rolls is paramount. The cooling effect will be obtained by a cooling water feed. The cooling water will be fed through ducts in the rolls. The following characteristics are highlighted below: Characteristics, including:
- Variable speed/friction by integrated potentiometer
- Manual or motorized gap setting from the front
- Automatic daily electronic brake angle control according to the relevant regulations
- Scraping knife from the front and/or from the rear
- Two hand control for closing the rolls against injuries by open roller gap
- Two drive motors with a drive power of 5.5 kW each at individually driven rolls
- Special safety technology and in particular sufficient access protection above the dangerous roller gap
- Preprogramming of mixing programs consisting of time, speed, friction and gap width
