Clay Processor Installs DCF Self-Cleaning Filter to Keep Up with Demand
A kaolin clay processing facility has discovered that the Ronningen-Petter® patented DCF self-cleaning filter provides measurable advantages in the processing of slurries.
(PRWEB) July 12, 2005 -- A kaolin clay processing facility has discovered
that the Ronningen-Petter® patented DCF self-cleaning filter provides measurable
advantages in the processing of slurries.
Improvements in the kaolin
clay facility had created a problem for its process engineers — finding a filter
to meet the facility’s newly doubled production rate. Their solution was the
Ronningen-Petter DCF-1600 multiplex self-cleaning filter. Because the screen on
the DCF filter is cleaned on demand and without interrupting production, a
consistently high flow rate is maintained across the system.
SITUATION
Engineers made process changes in the kaolin facility and needed a
filter that could protect the heat exchanger, keep up with the facility’s higher
throughput, and handle the unique screening characteristics of kaolin slurry. In
addition, backwashing filters installed in other areas of the plant ran the risk
of depositing water into the product and diluting the slurry.
RONNINGEN-PETTER SOLUTION
The facility’s engineers installed a
Ronningen-Petter DCF-1600 four station multiplex self-cleaning filter system and
have never looked back. The DCF filter mechanically scrapes collected debris
from the filtering screen with a disc that moves up and down the screen parallel
to the liquid flow, then purges the solids from the filter. This self-cleaning
action is performed without halting production, and provides the highest quality
filtering under continuous demand. Because the screen on the DCF filter is
cleaned on demand and without interrupting production, a consistently high flow
rate is maintained.
Higher Flow Rates — The high flow rates achieved
with the installation of the Ronningen-Petter DCF filter enable the filtering
system to keep up with the facility’s doubled production. And the high quality
filtering provided by the DCF filter protects the newly installed equipment that
is so critical to the maintenance of the improved production rates.
Does
Not Introduce Water into Product — Ronningen-Petter DCF self-cleaning filters
offer some clear advantages over the backwashing filters and vibrating gravity
screens typically seen in the clay industry.
Backwashing filters that
were already installed in other areas of the plant always ran the risk of
depositing water into the product and diluting the slurry. In contrast, the DCF
does not introduce any new fluids into the product, and the waste purged from
the DCF filter is in a small, highly concentrated form.
RESULTS
Increased production rates: DCF filters outperformed and replaced
several vibrating gravity screens by increasing throughput and reducing the
filter floor space required by 70%
Labor savings: Operators don’t need
to watch the filter, since the differential pressure across the filter media
conveys its performance and can be monitored automatically.
Material
savings: Saves the dollars spent on replacing vibrating gravity screens.
Superior flow rates: 30-200 gpm (113-756 l/min) at pressures to 150 psi
(10.5 bar).
Lower maintenance: Saves costs and time.
CONCLUSION
Ronningen-Petter DCF self-cleaning filters, by their very nature,
provide kaolin clay processors with higher flow rates and better quality
filtering than backwashing filters and vibrating gravity screens typically used
in the industry. The DCF-1600 filter meets the challenges of variations in clay
properties, particle size and flux rates to protect expensive processing
equipment.
