This segregation (based on materials segregated) is caused by centrifugal force as air and material enter the collector. A spinning action separates vacuumed material from the air without the use of any filters.
Dry centrifugal separators are especially useful for segregating large volumes of heavy or abrasive materials -granules, stones, broken glass, brick chips, wood and metal shavings, metal chips, etc. They can be used alone when the dirt stream is homogeneous and not dusty. Since most dirt streams contain mixtures of coarse and fine materials, however, centrifugal separators usually provide primary separation and filter protection before a filtration separator.
Dry separators are available in diameters up to 72″ and are sized based on the volume of air involved. They are typically equipped with a removable dirt can, hopper bottom with legs or hopper bottom with mounting pads. They are used to collect and hold vacuumed material.
High-efficiency separators use a high velocity vortex centrifugal action for higher separation efficiency or for pneumatic conveying. This type requires continuous discharge from the separator by the addition of a surge hopper for material storage.
The Spencer Top Hat® separator is a small centrifugal drum-top unit typically connected to a vacuum system via a jumper hose to act as a preseparator. It provides very convenient, localized separation and collection of recyclable byproducts or highly aggressive materials such as glass and metal fragments, before they can mix with the main dirt stream. It also avoids abrasive damage to the vacuum tubing system. There are two sizes for standard, customer-supplied drums; the Top Hat is easily transferred from drum to drum.
