Hein, Lehmann GmbH

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 Metallurgical expertise and more than 70 years of experience!

We offer you a comprehensive service and we manufacture our equipment using our largely self-developed machinery with exact dimensional accuracy and in highest quality.

PERFORATED PLATES
Stepping up to the plate

Perforated plates are used in various areas of Process 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 plates are available in numerous designs. Material quality, starting plate  thickness, perforation and surface finish can be individually adapted to your requirements.

CONIDUR®

Our tried and tested own brand for all Perforated plates. We are happy to offer you individually tailored solutions to suit your requirements.

RAW MATERIAL SCREENS

Clean separation, clear advantages

We can supply you with the classic raw material

screens (e.g. wire mesh, harp screens), screen panels and screen mats made of PUR plastic (polyurethane) and rubber.

HEIN, LEHMANN also offers the lightweight plastic screening made of Vibro-Flex mesh with plasticcoated wires, whether tensioned screen lining, wedged flat screen bottom or PU screen system (WS 85 / WS 83 or WS 2.10 with magnetic attachment). Suitable for all

conventional screening machines as well as special sizes on request.

In addition to basic screens, we also manufacture a wide variety of baskets and basket inserts (hardening baskets, charging baskets and charging racks, nitriding baskets, annealing baskets, washing baskets) as wire

mesh or welded constructions with wire meshes and wire grids for loading, stacking and for the hardening shop.

You don‘t have any concrete requirements or drawings yet? No problem! Together with you we will find out which solution is the best for you.

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®

We have designed, produced and launched onto the market the world’s first LIWELL® screening machine using the Spannwell® principle.

You could say that these are something like the technological screening nemesis for extremely difficult and/or moist bulk materials.

Other machines have to admit inferiority, for their revolutionary technology has been used worldwide for screening bulk materials for around 40 years.

WEDGE WIRE SCREENS

Tailor-made screens for everyone andeverything

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 as well as different profile shapes (combined with different cross bars).

Our wedge wire screens work almost without clogging, have an optimal open screen surface and have a long service life thanks to a wide range of material possibilities.

RIMA®/CORIMA

We offer our high-quality slotted screens in two own brands:

• Looped (RIMA®) for high vibration security

• Welded (CORIMA) for a highest degree of splitting accuracy
