High Speed Disperser Blades
Dantco Mixers Corporation has a line of stainless steel and abrasion resistant
Poly high speed dispersion blades in various styles to suit the particular
dispersion application. All stainless steel blades may be supplied with a
hard chrome plated coating or with plasma sprayed tungsten carbide coating
for long life in abrasive or high temperature mixing environment. Most blades
are stocked and available from 1" to 36" diameter, suitable for
laboratory, to pilot line, to full production. These blades are used in inks,
coatings, adhesives, ceramic, rubber and chemical industries. They are designed
to disperse, dissolve, emulsify solid/liquid/gas materials. All blades may
be bored to fit other than Dantco Mixers Corporation dispersers.

The blade is held by the top and bottom blade holder with 2 fasteners.
The top blade holder (shown on the left) has a welded hub with keyway
and set screws. This design is suitable for mounting a blade anywhere
on the mixing shaft, most of the time it is in the middle of the mixing
shaft. The blade position on the mixing shaft may be adjustable within
the length of the keyway on the shaft. |
 |
| The HSF style is the standard used for most dispersing appliations,
since it produces high shear dispersion, pumping action, and size reduction
especially for heavy agglomerates. It is used in processing paints,
inks, slurries and coatings. Available in diameters from 1" to 36". Dantco is
the only supplier to offer this style blade in 1" diameter size. |
 |
| The HSE style is a combination of F and G style blades
and offers intense turbulent flow with some shear, especially when used on
high vehicle viscosity and high solid solutions, resulting in good dispersion
with high pump rate.
This style is favored in dissolving resins. |
 |
The HSG style, high vane blade, generates a high pumping
action which tends to mix the entire batch efficiently, resulting in high
speed blending with low shear, but with excellent flow and circulation.
It is used in heavy bodied mixes that require higher shear as obtained
from paddle agitation.

| The HSO style blade offers high pumping action and high
shear. The hole pattern allows for maximum shear generation with less horsepower.
Other process characteristics are similar to the HSF style blades. |
 |
| The HSD style, characterized as the Ring/Disk Blade,
offers all the advantage of a rotor/stator assembly while retaining the versatility
of a single blade design. The inside sharp teeth shear pigments agglomerates
and discharge materials at great speed and pressure through the slots and
against the surfaces of the deflected rings. Mixing materials are
quickly reduced in size with little heat accumulation. |
 |
| The HSCC style blade produces high shear, pumping action, and size
reduction similarly to HSF style blade. The curved teeth of the HSCC
blade provide additional shear caused by centrifugal forces pushing the
materials through the venturi formed by the roundness of the tooth. |
 |
| The Poly Blades are best suited for the toughest dispersion
applications where abrasive aqueous system such as ceramic, titanium dioxide,
sand will immediately wear out standard high shear stainless blade. The
Poly Blades, formulated from non-sparking and medium temperature materials
(150 degrees F), should outlast other blades by a factor of 10 in most applications. |
 |
| The HSF-H style is same as HSF style with the inclusion
of a center hub with 2 set screws for mixing shaft attachment. This configuration
may be used with blades up to 8" in diameter. |
 |
| The HSE-H style is same as HSE style blade with the inclusion of a
center hub with 2 set screws for mixing shaft attachment. This configuration
may be used with blades up to 8" in diameter. |
 |
| The HSG-H style is same as HSG style with the inclusion of a center
hub with 2 set screws for mixing shaft attachment. This configuration
may be used with blades up to 8" in diameter. |
