Design and fabrication of a dust collection system.

Abstract

A lot of dust is generated during the course of various mine operation and also other economic activities most especially due to rock fragmentation. The dust is usually beyond allowable concentrations hence causing negative effects to human life and the environment. Wet suppression has been tried out but it interferes with the mine operations. This is why I came up with an idea for a dust collection- system which. couldn't interfere with operations and yet affordable. The dust collection system was designed and the fabricated to avoid the circulation of dust from point sources and the case. study was limestone dust in Tororo cement Quarry- The designed and fabricated dust collection system comprises of the hood for capturing the dust from a point source, a cyclone for separating dust using centrifugal force, a hopper for breaking the vortex and an airtight container for collecting the dust. The machine was also tested to examine its efficiency and the efficiency of the dust collection system designed was dependent on the length and diameter of the cyclone. Conclusions and recommendations were drawn from the discussed results got after testing. The prototype had an efficiency of 78%. total dust and replaceable filters and an air lock were mended for further cleaning of the air. The major costs to be incurred by the dust collection system designed are the power costs since it has no movable parts. The designed and fabricated system is the best to be used in all areas whether arid or not, but only needs availability of power.
