In-Line Disperser Mill
* Dispersing * Homogenizing * Deagglomerating * Milling

The In-Line Disperser Mill consists of specially designed saw tooth blades rotating at over 8000 peripheral feet per minute within a very closely sized, jacketed chamber, in order to induce intense shear and pressure on the product being pumped through the mill by the variable speed feed pump. Special hardened wear-rings are used to reduce wear.

MILLING CHAMBER AND BLADES

The milling chamber is provided with wear resistant liners, and is segmented for easy disassembly of blades and chamber components.

The blades and chamber compartments are interchangeable to provide for periodic interchange of upper and lower chamber, thus distributing any wear evenly.

The spacing between the blades and chamber wall is machined in the In-Line Disperser Mill, thus eliminating time consuming maintenance. Most applications require very significant wear before any drop in milling or dispersing efficiency is noticed, thus drastically reducing maintenance down-time and extending production runs to months or years.

The milling chamber is jacketed for cooling, as is the seal lubricant reservoir.

The very intense shear, results in significant heat input of the product, particularly if the product is high in viscosity. This must be taken into consideration when adjusting the feed rate. External cooling may be required for some products.

DOUBLE MECHANICAL SEALS

The shaft of the In-Line Disperser Mill is sealed by the same double mechanical seals used on the Schold Shot Mills. They are of U.S. manufacture and have been proven in hundreds of applications. They are provided with a pressure lubricant reservoir, pressure gauge and regulator for pressurizing with plant air. An air check valve is provided in case of plant air failure, in order to allow continuing operation.

A FEW CASE HISTORY COMMENTS

• In the textile dye industry, six passes through a media mill were replaced by one pass through the In-Line Disperser Mill at 12 GPM and one subsequent pass through a media mill.
  
  
• It is reported that the In-Line Disperser-Mill is of value in making gel-free solutions of high molecular weight resins which normally require boiling solvents for solution. Successful stabilization of resin solutions which resist emulsification can be accomplished with the In-Line Disperser-Mill.
  
  
• The In-Line Disperser-Mill may be the only milling process necessary to produce a finished product.
  
  
• In the manufacture of zinc oxide copypaper coating, coating was “off the grind gauge” at full pump rate (15 FPM).
  
  
• In making fluorescent “carbon paper” coating, one pass through the In-Line Disperser-Mill surpassed 48 hours of baIl milling.
  

How It Operates:

The product to be milled is slurred and pumped into the bottom of the milling chamber by the variable speed feed pump. As the product enters the first milling compartment, it is forced to flow in a thin film between the textured chamber walls and the saw-toothed blades in an area of very intense agitation. The shear and pressure developed between the material and material between the material and blades and milling chamber walls creates dispersion. The product continually being forced by the pump pressure then flows back across the top of the blade and into the next compartment, where a second pair of blades repeats the process.

***WARNING SAFETY STATEMENT***
As in all machinery, it is imperative that proper safety procedures training and supervision should be maintained.

Under no circumstance should the machine be cleaned, wiped, maintained or tampered with while shafts are rotating or with electrical power connected.

Electrical hardware, connections, wires and floor mountings must be periodically checked and, if necessary, repaired.
