Grinding and extraction Kemper HP

Whenever metal is ground, grinding dust, sparks, and noise are inevitably produced. The most significant occupational risks in metal grinding are associated with fine particulate dust, which can contain metals released from the workpiece and abrasive material particles. For example, when grinding stainless steel, the dust may contain iron, chromium, and nickel—all of which, when inhaled, can be toxic to your body.

One of the most effective ways to reduce the risks and exposure caused by grinding is to ensure a proper grinding station and efficient local extraction.

We provide the right solutions for this!

Kemper HP Grinding tables

There is one base model of the grinding table, available in four different versions with widths of 1000 / 1300 / 1500 / 2000 mm — so you can choose the size that best fits your needs.

All width versions share the same functional features:
– They effectively attenuate the most painful frequency range of grinding noise
– Offer top-class dust extraction and spark suppression
– Provide excellent working ergonomics

The robust steel construction enables handling of very heavy components without any risk of the table tipping over.

The top and both side panels can be opened when needed, allowing easy handling of differently sized workpieces, including the use of an overhead crane for loading directly onto the table.

The sheet metal, mineral wool, and perforated panel structure inside the side walls allow for rough handling without risk of mechanical damage.

All models have a large-diameter extraction outlet located at the rear top side, ensuring even high airflows are managed without annoying whistling noises.

Grinding tables are customized at our factory according to each customer’s specific needs

The most common accessories include electrical kits:

• Power sockets
• LED lighting
• Switches for controlling lights and extraction units

In addition, we can supply the grinding table with various surface materials, such as:

• Standard metal grating
• Rubber-coated grating
• Wooden or plywood gratings
• Plastic surfaces, etc.

If easy rotation of workpieces is important, you can also opt for a rotating plate with a foot brake, or a quick-release vise mount.

We also offer various transport base options — for example:

• Tables that can be moved with pallet jacks
• Tables permanently mounted together with a filtering extraction unit, allowing you to move both at once with a forklift

A popular, simple, and highly effective workspace setup can be achieved by arranging four tables in a square and placing a KEMPER extraction unit in the center. In this configuration, for example, the light switch or a usage-sensing power socket on one of the tables can trigger the extraction automation—opening the extraction damper and prompting the inverter-controlled fan to automatically adjust suction power based on demand.

This setup not only improves energy efficiency, but also contributes to better indoor air quality and lower noise levels.

The grinding cell can be easily separated from the rest of the space using KEMPER lamella curtains. The main advantage of these curtains is that they allow unobstructed passage. While effectively containing noise and dust, they still function as a “wall” that minimally interferes with movement and workflow. The color and UV protection rating of the lamella material can be chosen from a wide range of options.

We offer a large selection of lamella curtain materials and mounting components as ready-to-use kits. Don’t hesitate to reach out before trying to figure it all out on your own — we likely have exactly what you need!

Although we often refer to these as grinding tables, perhaps a better term would be “multi-purpose workstations.” Naturally, the tables are used for a wide range of everyday tasks — it’s common to see welding, drilling, threading, painting, assembly, and much more done on them. It’s no surprise that the optimal working height, good lighting, and strong extraction capabilities encourage workers to use the tables for a variety of purposes.

Important safety note: If solvent-based substances are used frequently, they pose a flammability risk and require ATEX-rated extraction systems. For protection against solvent fumes, we offer activated carbon cassettes for the tables and even high-capacity activated carbon filters for some of our extraction units.

Extraction and filtration units for grinding tables

Recommended ventilation rates and extraction methods:

• Direct exhaust outdoors, using KEMPER cast centrifugal fans in size ranges of 1,000 – 3,000 m³/h.
• Direct exhaust outdoors with filtration, as above but with an additional unit, for example the KEMPER WallMaster.
• Filtered air returned to the workspace, using a KEMPER centrifugal fan combined with a WallMaster unit — the most economical way to implement air recirculation.
• Filtered air returned to the workspace when using a grinding table on a mobile base or when a quieter/more compact solution is required, the choice is KEMPER MaxiFil (E12) or KEMPER FilterCell XL (M/W3).
• Filtered air returned to the workspace with the best possible purification result and very quiet operation, with the possibility to connect multiple units into the same system — the KEMPER WeldFil device series.

Two fans can be connected to one WallMaster unit, or one fan can be connected to two WallMaster units.
