Superior Cost-Performance Centrifuges Enabling Simultaneous Purification, Separation, Condensation and Recovery  Mitsubishi Disc Separators SJ Series

Mitsubishi Disc Separators SJ Series

Name. Byname. Abbreviation

Centrifuge, Selfjector, SJ, separation disc type, self-discharge type, 2-phase separation (clarifier), 3-phase separation (purifier), purifier, sedimentation equipment, sanitary type

Overview of Equipment

Mitsubishi Disc Separators are highly reliable separation disc centrifuges embodying proven purifier technology backed by the supply of over 65,000 units since 1940. They are capable of solid-liquid separation and liquid-liquid separation required in various wet processes such as purification, separation, fractionation, condensation and recovery.

Features

  1. Small and lightweight, power saving, superior performance, low cost
  2. Highly reliable drive shafting proven by the supply of over 1000 units a year.
  3. Bowl structure excellent in separation performance and discharge command response
  4. Pilot valve regulated total/partial discharge mechanism that ensures highly accurate discharge of solids
  5. The even higher-efficiency Super Partial discharge function (optional) minimizes liquid loss at the time of discharge and maximizes condensation of solids.
  6. Higher stability and maintainability ensured by well-balanced antiseismic structure.
  7. Full automation possible with the PLC-incorporated automatic control panel.

Uses and Suggestions

Mitsubishi Disc Separators offer extensive uses, from upstream to downstream, for solid-liquid separation, liquid-liquid separation and particle classification in various fields.
¦ÂSeparating solids from liquids that are difficult to filter; reducing filtration aids (culture solution, extractant, squeezed liquid)
¦ÂReducing the frequency of filter replacement and backwashing (improvement in various filtration processes)
¦ÂShortening stationary separation and condensation processes (grease or solvent/water separation, solid separation)
¦ÂRecovering solids escaping from the filter press, etc. (recovering solid particles and catalysts)
¦ÂPurifying, keeping clean and regenerating various liquids (lubricating oil, coolant, polishing fluid, various machining fluids)
¦ÂRemoving oily substances to unload water treatment (in various wastewater treatment processes)
¦ÂRemoving floating oil to prevent decomposition of solution (various machining fluids)
¦ÂRemoving water to regenerate and keep clean oily agents and solvents (cleaning agents)
¦ÂRemoving coarse particles for grading and fractionation (particle wet process)

Terminology

¦õeparation discs : Separation discs built in the bowl thin the liquid layer to shorten the sedimentation distance of liquid, thereby accelerating
¦æischarge : Solids accumulated in the bowl can be forced out by water pressure introduced from outside without stopping rotation of the bowl.
¦Ô-phase separation : Feed liquid is separated into two phases, i.e., solids (sludge + water) and purified oil.
¦Õ-phase separation : Feed liquid is separated into three phases, i.e., solids (sludge), heavy liquid (water) and light liquid (purified oil).
¦åentrifugal separation : Method of separation relying on centrifugal force caused by rotation of the bowl.
