Customized Options

As a leader in Separation Technology, FLSmidth is constantly looking at ways of improving operating efficiencies and ease of maintenance of our equipment. We continually develop new technologies, upgrades and programs which will enhance the performance of our customers' equipment.

FLSmidth's extensive product lines and staff of design, process and manufacturing engineers provide the experience in evaluation, specification and the fabrication of Filter Press parts and media for optimum performance in pressure filtration.

Shriver Skeleton Frame
The Shriver Filter Presss Skeleton can be supplied in side-bar or overhead plate suspension styles, 7 bar or 16 bar operating pressures (100 psi or 225 psi) and manufactured with carbon steel epoxy coated construction or with stainless steel clad frames. Contact FLSmidth to discuss your requirements.

Recessed Chamber Plates for Specific Applications
Filter plates can be supplied in a variety of materials including polypropylene with high heat and chemically stabilized resins. Corner Feed or Center feeds with filtrate, air-blow and cake wash porting arrangements to meet the application requirements are supplied. FLSmidth offers high pressure plates for 16 bar (225psi) operation and/or high temperature applications when needed.

Membrane Plates
High-efficiency membrane plates can be supplied for special applications to enhance wash effectiveness, minimize treatment chemical consumption, or minimize cake moisture. When using membrane plates, slurry is fed only during the initial fill cycle. After the feed pump has been switched off, the membrane inflation phase starts. The mechanical action of the force from the membrane plate surfaces on the filter cake is described as “squeezing” out the retained moisture from the cake. The advantages of membrane technology are that it generates higher filtration productivity through reduced cycle times, dryer cake and more efficient washing.

This increased productivity is a result of several factors:

  • Cake discharge from chamber more readily than recess plates
  • Differential chamber pressures are minimized by using the balanced membrane squeeze
  • Improved efficiency in cake washing applications reduces wash liquor consumption
  • Reduced cycle times where very long filtration times are experienced

 

Shriver Membrane Plate Filter Presses include all required ancillary components for pressurizing the membrane plates. These packages include squeeze water distribution manifolds, high pressure multi-stage centrifugal pumps, water storage tanks and all required valves and instrumentation for safe and reliable operation.

Filter Media Upgrades
FLSmidth's wide selection of filter media is available in a variety of materials (Polypropylene, Nylon, Dacron, Felts, etc.), in a variety of weave patterns and available with many advancements (molded rubber barrel necks, grommets, and seal edge treatments). FLSmidth’s decades of experience in pressure filtration has resulted in a complete listing of application, an extensive case-history with numerous performance evaluations of media covering a broad range of applications.

HYDRAULIC CLOSING MECHANISM – ELECTRIC TYPE
For the most demanding applications Shriver filter presses are fitted with an electrically powered hydraulic closing system consisting of a hydraulic power unit and a double acting hydraulic cylinder. The hydraulic system maintains the required pressure throughout the operating cycle. The hydraulic power unit consists of an electrically powered hydraulic pump, oil reservoir, strainer and all necessary valves, gauges, fittings, and hoses. A safety interlock of the feed pump and/or squeeze system is provided to disable the pumps until the required hydraulic pressure has been attained preventing accidental system pressurization.

Plate Shifting Mechanisms
Manual, fully automatic and semi-automatic units are available.
Cloth Washers

AUTOMATIC CLOTH WASHER MECHANISM
The Shriver fully mechanized plate shifter can be fitted with a cloth washer designed to separate the filter chambers automatically for discharge of the filter cake and provide periodic automatic high pressure washing of the filter cloth.
