  Dispersion Blades

  <p>High speed dispersers use a disc style agitator blade. The main function of dispersing is not performed at the disc but as the product leaves the blade. To produce the laminar flow for dispersion, the disc must produce horizontal discharge of the product. It is therefore important to insure the shaft is vertical. Dispersion blades are fitted with either alternating teeth or grooves. These features results in rapid shift of brief overpressure and under-pressure zones. The rapid alternating pressure zones aid in wetting and mechanical separation of the pigments. The size of these teeth contribute to the flow generated by the impeller.</p> <p>Dispersetech manufactures a wide selection of quality high speed dispersion blades. The designs provide a varied mix of both high shear and flow. Standard blades are constructed of 304 stainless steel, but other metals are available on request. Plastic and Urethane blades are available as well. In order to improve wear performance, we offer heat hardening as well as various ceramic coatings. The impellers are available in many blade sizes to meet the batch size requirements.</p> <p>Our blades can be bored to fit any of the common dispersion mixers including Myers, Cowles, Hockmeyer, Schold, Schar, etc. Our selection includes the Sawtooth blade, the workhorse in the industry as well as more exotic designs such as ring blades, poly blades and louvered blades.</p> <p>These mixing blades find uses in many chemical processing industries including paint, coatings, adhesives, cosmetics, pharmaceutical, etc.</p>

  Grinding Media

  <p>Grinding media is used in wet milling and dry milling operations.  Grinding Media is typically a bead of uniform size, shape, and density.  The media is agitated in high concentration with a slurry (or mill base) to be ground.  In a small media mill a central shaft agitates the media and slurry.  Energy is transferred from that shaft to the nearest layer of beads and from that layer to subsequent layers of beads.  It is within that power transmission that the mill base is exposed to extremely high shear and impact forces.   </p> <p></p> <h2>Media Selection</h2> <p></p> <h3>Media Size</h3> <p>Media Size is chosen both based on the type agitated equipment or mill and the agglomerate size of the slurry. For best stress transfer in a mill it is traditionally recommended that media diameter to particle diameter be 10:1 or greater.  Large media enhance impact forces while small media cause more collisions.</p> <p></p> <h3>Media Density</h3> <p>Media Density affects impact energy in the mill.  Denser media impart higher impact forces.  However, there are limits.  Mill base viscosity must be sufficient to support these high densities.  Dense media in low viscosity mill base can result in increased media packing, temperature rise, and mill and media wear. </p> <p></p> <h3>Media Shape</h3> <p>While some mills will use cylinder and other shaped media, Bead mills use spherical media.  The overall quality of the sphere is still important.  It plays a role in the mill wear and heat generation.  A quality sphere produces the best milling performance in a small media mill.</p> <p></p> <p>All grinding media is not created equal. DisperseTech offers a broad range of media for you wet milling operation. We can assist with media selection for your particular products and production equipment. Whether you operate sand mills, horizontal mills, basket mills, attritors or vertical mills, we have the media you need. From inexpensive sand, to glass, zirconium silicate, zirconia oxide, chrome steel and steel shot we carry a braod range of products. We can assist in determining the appropriate material and charge for you mill.</p>
