cutting mills (granulators) with force feeding device for max. throughput at size reduction. (PET bottles, plastics bottles, canisters, packing materials, containers,...) TO INCREASE THE THROGHPUT OF A GRANULATOR A SCREW CONVEYOR IS UTILIZED FOR A TECHNICALLY NEUE HERBOLD Maschinen- und Anlagenbau GmbH, D-74889 Sinsheim-Reihen offers a large range of machines and plants for size reduction and recycling of plastics scrap, from production or waste collection. To increase the through-put rate of a granulator used for size reduction of loose, unpressed plastics a force feeding technique was developed. A screw conveyor is utilized for a technically optimized material feed. Via conveyor the material is fed in the feed hopper. The transport to the grinding chamber is now no longer only based on the principle of gravitation - in fact the material is now fed to the grinding chamber by one / or more vertically assembled screws. Depending on the required granulator size the number of screws, the rotation speed as well as the drive capacity can vary. A transport screw equiped with a load-dependent control as well as a frequency converter prevents…

Active batch balancing & food conformity & CIP suitability In the food industry, absolute hygiene is of crucial importance, with high demands being placed on the measurement technology to be installed in terms of design, functionality and reliability. In the beverage industry in particular, these requirements can be very specific. A Peruvian beer manufacturer was looking for suitable solutions for overfill and running-empty protection for its process tanks with different solid and liquid raw materials. The malt dosing system was designed with innovative RF technology. Capacitive limit switches from UWT were installed, which are designed for high temperatures and applications with highly caking materials such as the viscous liquid of the malt mixture. It tastes better when you know your limits The difficulty in beer production lies in controlling the correct malt dosage during the addition of water for dissolving. This was due to the fact that the grain became very sticky after moistening, which led to false alarms for…

Goudsmit Magnetics (Waalre, Netherlands) has developed a new pipe magnet that requires half the installation height of its predecessor and is also twice as strong. Manufactured entirely from stainless steel, the magnetic separator contains a core of neodymium (NdFeB) magnets and creates a flux density of 12,000 gauss. The conical-shaped magnet core contains more pole plates, so even 30 µm particles stick to more engagement points. This results in a higher degree of separation and also makes it possible to capture smaller metal particles in addition to coarse ones. Steel particles present in the product flow such as bolts, nuts, washers, screws, small metal balls, broken threads and clips can be effortlessly separated from grains, corn, flour, wheat flour and other incoming goods flows. The new magnet system is suitable not only for mounting in free-fall pipes, but also for pressure pipes. The stainless steel bullet magnet can be used in food but also other industries. Low installation height & compact design The 12,000 gauss pipe magnet was developed in response to specific market demands. The first requirement was to…
