Physicochemical Problems of Mineral Processing
2011 Vol. 47 267-274
EN The paper presents the results of investigations on classification of different mineral waste on screens with flat screens and rectangular riddles. We developed three different constructions of such screening and subjected them to tests and process examinations aimed to determine their efficiency an[...]

Physicochemical Problems of Mineral Processing
EN This paper presents the results of considerations concerning the ratio of blocking of screen holes and the importance of particular independent variables affecting the process of blocking of sieve holes. The phenomenon of blocking the holes is unfavorable since it reduces the flow area of the lower [...]

Physicochemical Problems of Mineral Processing
EN The aim of this paper is to describe the process of sieve holes blocking. A series of tests and their results revealed a dependence describing the value of an average screen blocking coefficient as a function of two main factors affecting the process. These parameters are the toss indicator and the [...]
