dust exhausting and separating for ceramics industry

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.
APPLICATIONS FOR CERAMICS INDUSTRY
Technical ceramics
dishes
adornment ceramics
sanitary ceramics
tiles
ceramic based abrasives
high-performance ceramic
structural ceramics
industrial ceramics
functional ceramics
engineering ceramics
electrical ceramics
cutting ceramics
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 separating 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.
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.
YOUR BENEFIT
KELLER PLUS
Positive experiences of several years have shown, that Keller
Lufttechnik's solutions ensure an efficient, failure-free and
environmentally sound operation.

ductwork, exhaust technology, sound insulation, services).
Your benefit: ONE competent contact person no warranty-relevant interfaces.
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.
