Highest productivity... lowest downtime...
Designed and manufactured at our Southern Division specifically for medium run deagglomerating, dispersing and milling of inks, paints, dyestuffs, adhesives, pharmaceuticals, foods and other fluids where frequent color or media changes are necessary!
Schold’s Model F-600 Shot Mill is a 41/2-gallon, sealed and pressurized, high-speed continuous media mill designed for maximum productivity over a wide range of viscosities or thixotropy, moisture or air-sensitive material.
Because of its many unique features, solvent losses and product drying on the filter are eliminated, assuring higher production and feed rates than conventional open mills, ball or pebble mills and, in most cases, three-roll mills.
Clean-up, color or media changes are accomplished in minutes due to Schold’s unique hydraulic lift-mounted agitator assembly and dumping chamber design, thus assuring lower downtime for even higher productivity!
And, like all Schold products, F-600 Shot Mills have earned the reputation for being the most rugged and reliable production units in the industry.
How it operates
The material to be processed is pumped into the bottom of the grinding chamber by the feed pump. A variation of the pumping rate will determine the dwell time of the product in the mill and the degree of dispersion. The product is forced upward, passing through the grinding media which is fluidized by the velocity and agitation. Concurrently, milling occurs by a combination of rubbing and impingement between adjacent media particles and between the media and the agitator discs and chamber walls.
Atop the milling area is the drop-out zone where there are no agitator discs. Most of the media settles back into the milling area. The continually rising, ground product then passes through the mill filters at which point any remaining media is filtered from the product. The product continues to flow upward through an annular space between the filter and the shaft into the sealed discharge area.
When the run is complete, the mill head and shaft are unlocked from the jacketed chamber and raised by a double-piston, air-over-oil hydraulic lift. The swivel-mounted grinding chamber is tilted and the media dumped into a storage container for later use with the same color. The chamber agitator assembly and lines are then swabbed free of product and fresh media is installed in the mill chamber. The agitator assembly is lowered and locked and the next color is ready to run in minutes.
