Selectors TPS TECHNOPOUDRE are designed to carry out a granulometric cut on gross products, mixed or crushed. It is characterized by are high output of cut, its reduced number of internal parts and its possibility of construction with a cast solid body avoiding the multiple mating planes, thus allowing an easier cleaning.   Apparatuses TPS can carry out a selection of the granulometry of the product uninterrupted with possible recycling of the large particles in a crusher.   The limit of separation is function of the balance between the centrifugal force and a centripetal aeraulic force exerted on the particle. The granulometric cuts are also related to the intrinsic characteristics of the product (form, density…). The adjustment of the TPS is very simple and allows to optimize the cuts by simple variation speed. An adjustable device is designed to reach important outputs of selection. All the dynamic functions of selection are gathered in head of an easily extractable and adjustable selection out of l' apparatus. The TPS can carry out selections of 10 with 200µm according to the products to be treated.
