PRECISION SIZER |seed sizer|seed sizer|corn sizer|bean sizer With precision sizer you have to Keep in mind at all times the Oliver Gravity Separator is not a "cure all" for the processor’s problems. The gravity separator is a specialized piece of equipment during the precision sizer process designed to separate particles of a similar size that differ in weight. Oliver Gravity Separators should not be used as a cleaning machine to remove dust, dirt and other refuse. The gravity separator should not be used as a sizing machine.Screeners can do this job more efficiently. In all processing situations, the best results are obtained on the gravity when the product has been thoroughly pre-cleaned and sized, using the proper equipment for those purposes. Under these conditions, the gravity separator is able to show what it can really do! Many customers ask us how we can determine when we are getting the most from a gravity separator. This is an extremely difficult question to answer because not all people want to accomplish the same thing by operating their gravity. We manufacture gravity separators to make a separation based on particle density.To do this, it is first necessary that the product be cleaned and properly sized. Since size, shape and weight of the product directly effect the separation, it is imperative that the product be classified according to size and shape before attempting to make a separation on the basis of weight. The most positive method of testing to determine the effectiveness of a gravity is through the use of a Density Test, whether measuring in Pounds per Bushel, Pounds per Cubic Foot, Gram per Cubic Centimeter or Kilogram per Cubic Meter. By using this test, determine the difference in bulk weight per unit volume between The heavy and light product. The gravity should be set to obtain the maximum weight difference between the light and heavy products. The test weight of the heavy, middle and light fractions should be recorded along with the machine settings necessary to obtain this. This gives a written record of the operation of the gravity and the settings necessary to obtain that particular separation. These can be used as a reference when processing similar products in the future. |
