EQUIPMENT AND PROCESS FOR PRODUCING HOMOGENEOUS COMPOUNDS OF LOOSE SOLID SUBSTANCES

摘要

Equipment and process for producing homogeneous compounds of loose solid substances by continuous mixing-in ingredients of accurately measured quantity (weight) in a time unit and in accordance with the ratio of relative relation of weight of each ingredient with regard to the other mixing-in ingredients. Mixing-in is carried out into air stream. Invention belongs to the branch of technology for the production of compounds of loose granular substances. Problem resolved by this invention is to avoid mixed-up quality less than the maximum, i.e. to obtain absolute homogeneousness in all volume units and weight respectively. Equipment for producing homogeneous compounds consists of pneumatic transport device comprising a radial fan (2) with shaft (10) driven by electric motor (9) in housing (3), suction tube (4), discharge tube (5) and unit for continuous mixing-in as Figure 2 comprising elecromotor drive (14), which by means of mechanical transmission gear (11) drives worm (13) having continually changeable and accurately adjustable rotational velocity depending on results of mathematical analysis of operation. This invention is mostly suitable for the production of animal feeding compounds where a hammer mill (1) is an element of the equipment. It can be used in any other industry where it is necessary to produce homogenous or intentionally unhomogeneous compounds of loose granular substances.
