• Conventional Thickener
  . Conventional thickeners, also called single-compartment or unit thickeners, are circular, continuously operating thickeners. Conventional thickeners impart downward velocity to the feed via feedwells. Different design variations include the following: • Bridge-supported thickeners are most common...
• A Guide to Understanding and Mixing Thickeners
  solution can be produced in the VersaMix. in considerably less time than in conventional mixers. A typical mixing procedure is as. follows: ·. Water is added to the vessel of the VersaMix. ·. Agitators are turned on and the speeds are adjusted to create the proper flow. patterns and vortex...
• Manufacture of Tomato Sauces and Ketchups
  . · Once mixed, the product may be passed through a high pressure homogenizer or. colloid mill to obtain the required consistency. The Problem. A number of problems can be encountered when using conventional agitators: · Additives designed to thicken the product tend to form agglomerates which...
• Production of Flavor Emulsions
  . to the processor: * Hydration of gums and thickeners is one of the most difficult mixing operations. In some cases the solution has to be agitated for a long period to ensure the gum is fully hydrated. * Agglomerates can easily form. These are not easily dispersed using conventional agitators...
• Preparation of Petfood Gravies and Gels
  into the vortex created by the agitator. · Mixing continues after the powders have been dispersed, to allow hydration to be. completed and the desired viscosity to be obtained. The Problem. Dispersion of gums and thickeners using conventional agitators can give rise to several. problems: · Potential full...

• Great balls of ceramic
  " -- a propagation of surface cracks in the rolling contact. zones -- caused by denting from hard contaminants as found in machine-tool environments. But hard contaminants can also dent bearing balls. Torrington says tests show WearEver hybrid bearings can live 10 times longer than conventional...
• Great balls of ceramic
  tests show WearEver hybrid bearings can live 10 times longer than conventional all-steel bearings made of 52100 steel, even when run with marginal lubrication or in the presence of hard contaminants. Another company using Cerbec bearing balls is New Hampshire Ball Bearings, Precision Div., Chatsworth...
• The Lowdown On Lubricants For Rolling Bearings
  to the grease failure chart in Fig. 2.). In applications where bearing operating temperatures will fall below -4 F (-20 C) or exceed 250 F (121 C), lubrication with conventional grease may be completely unacceptable—and prompt a need for specialty types and/or different lubrication methods. The lubricant...
• Predicting lube life
  versa. Larger speed reduction factors shorten grease life. For reference, conventional single-row, deep-groove ball bearings have a kf =1.0 and a DN limit of about 300,000. Speed effects vary among greases as well. For example, so-called channeling-type greases often used in double-shielded...
