DUST EXHAUSTING AND SEPARATING FOR CERAMICS INDUSTRY

THE TASK

Ceramic-based products are applied in many industries, e.g. technical ceramics (electro-technology, medical engineering, universal mechanical engineering / machine tool manufacturing, daily commodity ceramics like sanitary ware, ceramic dishes) or heavy ceramics (tiles, ducts...) - wherever, the base for manufacturing is ceramic material.

Fine dust emissions are created during manufacturing of all these products that often cannot be avoided even on use of modern machines and technologies. Capturing, exhausting and separating these dusts is mostly necessary due to the production process, the product's specifics or due to employment laws respectively environmental laws.

Handling of fine dust emissions gets additionally complicated due to the fact that the dust may be harmful to health. Therefore, this subject is very important.

The multitude of industrial processes and methods during manufacturing of ceramic products leads to different airborne substances. Type and quantity of the dusts to be separated, their physical features and aggregate state specify the selection of the suitable separating proceeding.

KELLER PLUS Positive experiences of several years have shown, that Keller

Lufttechnik's solutions ensure an efficient, failure-free and environmentally sound operation.

product recycling high availability

clean air recirculation constant air volume

compact construction system solutions extensive references. Your benefit: Sophisticated systems that are continuously adapted to the latest state of the art.

THE SOLUTION

Keller Lufttechnik has got long-time experience and extensive knowledge in air filtration system solutions, also especially in separation of fine dust emissions.

Keller Lufttechnik is able to ensure all benefits of an ideal sepa- rating procedure, maximum occupational safety, clean breath air, optimal safety in operation and environmental protection by means of systematic projecting.

Keller Lufttechnik developed and applies the modular shape of filtration units and their performance features and provides ideal solutions in the field of typical ceramic applications.

YOUR BENEFIT

ADVANTAGE PRODUCT RECYCLING When separating airborne substances, the SINBRAN filtration technology allows pure product recycling by ideal PTFE membrane surface filtration. Your benefit: Quality assurance when recycling the separated materials as no filter material residuals are within the separated material. ADVANTAGE HIGH AVAILABILITY Excellent lifetime when using SINBRAN filter technology. Keller Lufttechnik's warranty: 20000 operation hours and a high availability ensure an economic unit operation. Your benefit: Reductions of spare parts costs, waste disposal costs as well as loss of production times and maintenance expenditures. ADVANTAGE CLEAN AIR RECIRCULATION Air recirculation into the working room because of small and constant residual dust concentrations upon the complete lifetime of the SINBRAN filtering elements. Your benefit: Savings in energy costs and measures regarding air make-up of the exhausted air volume. ADVANTAGE CONSTANT AIR FLOW RATE Constant air flow rate by ideal surface filtration in combination with compressed air pluse cleaning during operation. Your benefit: Constant operation conditions even on large dust quantities in the filter. ADVANTAGE COMPACT DESIGN Compact module design for an ideal adjustment to the necessary suction output. Your benefit: Investment optimisation and minimisation of the required space. ADVANTAGE SYSTEM SOLUTION Projecting of system solutions (individual capturing, ductwork, exhaust technology, sound insulation, services). Your benefit: ONE competent contact person - no warranty-relevant interfaces.

FILTER ELEMENTS

SINBRAN®, a combination of sintered, porous polyethylene and laminated GORETM-membrane, joins the advantages of membrane filtration with rigid body filtering. The stable, rigid body offers a large filter surface and requires only less space. This construction provides also a high mechanical capacity and long service life. The GORETM-PTFE-membrane provides surface filtration with a very high filtration efficiency because of the extraordinary even structure. The dust particles are kept back almost completely at the filter surface. Thus, the sintered body keeps out of dust particles and gets not clogged. The consequence is an extremely low pressure loss compared to conventional rigid body filter elements. Short compressed air pulses during the filtration process provide an efficient cleaning. SINBRAN® is a co-production between Keller Lufttechnik and W.L. Gore & Associates GmbH.

Compared to conventional filter elements, SINBRAN® provides clearly less pressure losses. Pre-dusting with limestone powder for a constant air-to-cloth ratio.
