Applications

  • CBN grinding on various oils
  • Steel, carbide, Inconel, cast iron and aluminum grinding on oil and and water soluble coolants
  • Honing, super-abrasives, lapping, polishing and burnishing processes
  • Ceramic and glass grinding and polishing
  • Component and parts washing
  • Waste water effluents

Benefits

  • Unique Design

    The Star Filter Element's unique design of the element's star shape and the filter panel's compact, rectangular design provides the maximum filtration area in the most economical use of space. Based on your application, selecting either the synthetic double-layer weave media, stainless steel wedgewire or patented fuse-bonded stainless steel microscreen filter panels will provide reliable, maintenance-free, effective filtration down to 1 micron.

  • Advantages

    • Ideal for use in vacuum filtration on filter drums, screens and removable vacuum elements like HydroFlow Star Filtration Systems
    • Enhance filter clarity and performance for rolled media vacuums and pressure filters
    • Completely safe, food grade product
    • Aids in the recovery of precious metals with low ash content upon incineration
    • Non-abrasive filter media is not harmful to pumps, valves and equipment
    • The element's star shape and filter panel's compact, rectangular design maintains structural integrity after removal from the filter
    • Precision built and interchangeable elements
    • Each element can be removed easily and without stopping the system when multiple elements are installed
    • Positive seal connection

  • Principles of Filtration Cycle

    • Cellulose precoat is used to provide a true depth cake and achieve filtration down to 1 micron
    • The powdered cellulose is stored in a hopper that is equipped with an automatic feeder
    • The cellulose is mixed with clean coolant and the slurry is pumped to the distribution ring on the Star Element
    • The cellulose is quickly drawn to the filtering surface creating a filter cake for trapping solids

  • Regeneration Cycle:

    • Solids trapped in the cellulose cake become compressed and dense. As the cake builds, it restricts the flow and creates a negative pressure in the suction pipe. The system senses the increase in the vacuum and initiates the automatic regeneration cycle.
    • The regeneration valve opens
    • Clean coolant flows from a raised tank supplying coolant to the process
    • Additional coolant flows back towards the Star Element
    • The backflow of coolant gently releases the element's compressed filter cake
    • The dense solids mass quickly settles on the conveyor for removal
    • A pneumatic cylinder then lifts the element and "bumps it" in the wet seal to further clean the surface
    • The regeneration valve closes, tanks return to normal operating levels and the precoat cycle begins
    • A conveyor moves the solids out allowing them to dry on the incline before being dumped
