STUDIES ON THE EFFICIENCY OF THE USE OF DUST FILTERS AT THE WORKING FACILITIES FROM THE COMPOUND FEED FACTORIES

Abstract

The technological process of obtaining the compound feeds involves the mixing of the milled cereals in the mills of the work installation with protein flours, mineral salts and vegetable oils. During the activities of grinding cereals and obtaining granules of finished product, it can be detached fine particles which forming the dust that is released in the air. This article analyzes the technological process for the preparation of compound feeds with accent on the stages of grinding, granulation and homogenization of the finished product, for study the problems who can appear due to the eliminated dust in the air by the working installations. The measurements effectuated attest the efficiency of the use of special filtres and automatized control systems of dust concentrations according to the pollution norms imposed by the European Union in order to protect the environment.
