Application

Design

Operation

The IDMS Blow-Through Rotary
Valve has been especially designed
and developed for the in-line feeding
of non-homogeneous alternative
fuels into pneumatic conveying
systems within the Cement, Lime,
Gypsum and Power industries.
Robust in design and performance
the IDMS is capable of feeding a
wide range of alternative fuels
including shredded plastics, foil
chips, conditioned sewage sludge,
wood chips & saw meal, palm kernel
shells, rice husk, animal meal and
various mixed combinations.

A robust, compact, space saving
design ensures high efficiency
performance. Durable and reliable
air-sealed bearings protect the units.
Wear parts thus ensuring optimal
and stable pneumatic conveying
conditions with minimal air leakage.

The IDMS Blow-Through Rotary
Valve is used as a feeding device to
directly feed of non-homogeneous
alternative fuels into pneumatic
conveying lines at conveying
pressures of up to 300 mbar.
Typically, a pre-feed device
positioned between the upstream
material silo is used to consistently
feed the material into the IDMS. The
integral scrapper and cutting blades
are designed to prevent the IDMS
from becoming blocked with foreign
bodies or oversized particles. For
ease of use and maintenance, the
high abrasion resistant wear parts
are all exchangeable from the plant
side without the need to completely
disassemble the unit. The geometry
of the unit’s inlet, chambers,
conveying channel and outlet
guarantee efficient material flow into
the pneumatic conveying line thus a
high material conveying to air ratio is
achieved.
