The circular economy increasingly demands robust and affordable milling applications. For a client in Hungary, Poeth supplied a 160 kW Hammer mill line for the grinding of printed circuit boards. To make recycling profitable, purchasing costs are important, but the costs of wearing parts are certainly also an important factor. Wear parts of the hammer mill, such as hammers and sieves, are cost-effective and freely available on the market. Poeth is currently building a line for grinding dried foods (residual flows from the food industry) such as: parsnip, carrots, potatoes (from the fries industry). For small capacities, Poeth has a cost-effective mini hammer mill in the range. The mills meets the latest ATEX requirements, including all necessary documents. The machine is pressure-resistant. A hammer mill is basically a machine with which coarse particles can be ground into smaller particles. The reduction of material particles is done by subjecting the material supplied to rapidly rotating hammers, which are hinged to the rotor. At the bottom is a sieve, which drains the product as soon as the desired grain size is reached. This screen deck is relatively easily interchangeable. The air management is also very important for the fineness and capacity. Poeth has been producing mills since its foundation in 1921, back then for the authentic wooden grain mills. Hammer mills are relatively simple and are capable of grinding many types of material. However, the hammermill is not suitable for very fine milling (e.g., < 100 microns). Also not not for coarse milling (e.g. > 700 microns)
