Embodiment Construction

[0029] see first figure 1 According to a preferred aspect of the present invention, the solid particle material separation system includes a superfine pulverizer 1 fed by a screw conveyor 2, two separators 3 for classification that are arranged downstream of the superfine pulverizer 1 and are connected in series , 4, the filtering device 7 and the suction device 8 connected to the outflow pipe of the separator 3,4.

[0030] The two separators 3, 4 are in fluid communication with each other by means of a connector 5, and each separator has, at its bottom part, a rotary discharge valve 6a, 6b, for example in the shape of a star. The suction device 8 is also designed to generate a forced flow of air during the suction and can be equipped with a device 101 for regulating the generated air flow.

[0031] Thus, the material to be classified is conveyed by means of a screw feed conveyor 2 to an attritor 1 in which said material is ground until it assumes the form of particulate matt...

Abstract

A longitudinal micrometric separator (3) for the classification of solid particulate materials comprising an outer casing having an inflow opening and an outflow opening for the particulate material, a collection chamber (11a) at the bottom, as well as a sliding support (10a) for the particulate material extending substancially along a longitudinal drawing axis, in which the material is conveyed in the direction of the aforesaid longitudinal axis by a forced fluid flow. The sliding support (10a) comprises at least one first inclined wall (15a), lying in a plane parallel to the drawing axis, and at least one dropping channel (17a) with axis parallel to the drawing axis and connected to a side end of the same inclined wall, the other side end of the inclined wall being set at a distance from the internal surfaces of the casing.

Description

technical field [0001] The present invention relates to a micrometric separator for classifying mixtures of solid particulate materials in which a fluid stream, preferably an air stream, has the ability to transport the particulate material and guide it to slide along a suitable container wall such that, based on the different physical properties possessed by the particles Particle separation function based on particle size. This particle size separation (ie particle separation) is of particular importance in the case of pulverulent organic substances, since material mixtures are obtained with a specific particle size (granulometry) and with organoleptic properties which can be determined a priori during the classification process. Also in the context of inorganic material mixtures, the separation of mixtures with a uniform particle size is of great importance, for example, with regard to materials used in the construction industry. Background technique [0002] Of the vari...
