Paste thickeners and E-Cat
Deep-Cone™ Paste and PPSM
thickeners — Ultimate
underflow solids
concentrations
FLSmidth is the world leader in deep
cone thickening technology with
more installations in more applications
than all competitors combined.
EIMCO Deep-Cone Paste Thickeners
produce underflows concentrated to
near their limit of pumpability. Their
deep tank design maximizes pulp
concentration, and produces uniform,
non-segregating, paste consistency
underflow slurry.
The Dorr-Oliver Paste Production
Storage Mechanism (PPSM) is a
unique device and process designed
to “flash thicken” solids to paste
consistency. The paste viscosity is
controlled to permit storage.
Paste thickeners maximize the
efficiency of a range of applications
such as:
• Dry stacking of tailings
• Underground paste backfill
• Counter-current decantation (CCD)
• Autoclave leach feed
• Maximum water and chemical
recovery
• Increase downstream process
efficiency
E-Cat® ultra-high rate clarifier
and thickener
This rakeless design uses novel
technology to accomplish both
clarification and thickening in a single
unit with minimal area. The design
advantages include:
• Low capital cost compared to
conventional thickeners
• Low maintenance costs due to
no moving parts
• Much smaller area required
compared to conventional
thickeners
• Low operating costs, low
flocculent consumption
• Counter-current decantation
(CCD)
