Circular saws designed for specific requirements are a Hertwich specialty. The Hertwich circular sawing plants are an important part of automated billet production facilities. After cooling logs pass over a combination of storage conveyors and roller table lines to arrive at the billet saw, to be cut into short or long billets as required.

The Hertwich Packing systems comes from single layer bundling units with semi-manual strapping systems to multi-layer stackers for short and long billets with fully automatic strapping, feeding of wooden runners and weighing.

Our briquetting presses make swarf handling easy. They also significantly reduce the space you need for storing swarf boxes; pressed chips are less voluminous than loose ones. Aluminium briquettes are of high density, suitable for direct charging into standard reverb furnaces. Metal recovery during remelting is excellent, similar to that of ingots.
