PERFORATED PLATES Stepping up to the plate Perforated plates are used in various areas of p rocess and preparation technology such as mills, centrifuges and fluidised bed plants. The special conical perforation ensures, among other things, less contact resistance, fewer blockages and higher throughput. In addition, our perforated plates are work-hardened during production. As a result, they have a higher wear resistance. A special manufacturing process enables the finest perforated plates to be produced in initial plate thicknesses that can be many times the hole width. The perforated...

WEDGE WIRE SCREENS Tailor-made screens for everyone and everything Our wedge wire (or slotted) screens are successfully used in almost all branches of industry, such as the food industry, the brewery and beverage sector, waste water and process water treatment, the chemical industry, the sugar industry, water and environmental protection, the stone and earth industry and general mechanical engineering. Depending on the application and requirements, the wedge wire screens can be individually adapted to each individual case by means of any conceivable geometric shapes, materials, dimensions...

SCREENING MACHINES Top screening machines in the industry Our screening machines, whether circular vibratory, linear vibratory or classifying machines, are suitable for recycling applications as well as for screening bulk materials (coal, sand, hard rock) and thus cope with even problematic applications that cannot be classified or can only be classified with difficulty using conventional screening machines. With our screening machines, we support major projects such as the construction of new power plants or equip regional medium-sized companies with modern separation technology. LIWELL®...

CONVEYOR BELTS Customised belt solutions Conveyor belts from HEIN, LEHMANN are to be found in virtually all branches of industry due to the wide range of steel qualities and the enormously wide range of dimensions, especially where process engineering processes at temperatures from -150°C to approx. 1,200°C are required or where non-metallic means of transport are unsuitable: from A to Z, from automation to the zinc mining industry. Benefit from our extensive technical and m etallurgical expertise and more than 70 years of experience! We offer you a comprehensive service and we manufacture...
