Mixheads

ESCO’s FFH system overcomes the challenges of costly bulk storage and pre-blending facilities along with the problems of settling, viscosity increases, separation and agglomeration which have all contributed to the limits of batch blend systems. Fillers are metered and mixed continuously without batching.

Overview

ESCO’s FFH system overcomes the challenges of costly bulk storage and pre-blending facilities along with the problems of settling, viscosity increases, separation and agglomeration which have all contributed to the limits of batch blend systems. Fillers are metered and mixed continuously without batching.

Blending

Advantages:

  • Shear rate independent of filler feed rate insures complete and thorough mixing
  • Filler ratios can be changed on the fly
  • Blends of fillers can be utilized
  • Filler types can be changed on the fly
  • High filler ratios are possible
  • Total output rates can be changed on the fly without altering filler ratio
  • Limited residence time prevents separation, agglomeration, and time for filler to react adversely with the liquids
  • Minimum particle damage
  • Virtually any free flowing filler has the possibility of use in the FFH

High volumes of dry filler can be added to the system. We have processed the following fillers:

  • Reground scrap rubber and rigid and flexible PU
  • Cellulose
  • Carbon black
  • Expancel micro spheres
  • Rubber tire crumb
  • Phosphorescent minerals
  • Chopped EVA scrap
  • Mineral fillers such as calcium carbonate, silicon carbide, silica sand, aluminum hydroxide, alumina, phosphorescent minerals, barium sulphate, and abrasive particles like garnet and silicon carbide
  • Metallic particles
  • Glass micro balloons, peat moss, expandable graphite, perlite, mica, fly ash, melamine (ground and unground),

Mixhead Model Features

  • Capable of handling multi-component liquid streams
  • Polyurethanes, epoxies, and polyesters can be processed
  • Can be used as a pre-blender or final mixer, but there’s no need to pre-blend; the Filler Fed mix head is designed for incorporating a wide range of solid fillers directly into multi-component systems
  • One or two filler streams can be processed
  • Each chemical stream has its own recirculation/calibrate valve at the head

Nominal Output Rates:

  • 5-400 lbs/min [Depending on ratio + filler bulk density]

Optional Features

  • Optional computer control stores recipe for easy set-up
  • Flow meter control on pump drives is also available
  • ESCO tailors the system to meet your needs.
