1.0 INTRODUCTION
This experiment was conducted to study the effect of cyclone body diameter upon collection efficiency. The cyclonic separator is an important and popular type of dust-removal equipment. In this experiment 50 gram of kaolin was used as sample to study the particulate collection efficiency of double cyclone system.
A cyclone collector can be defined as a structure without moving parts in which the velocity of an inlet gas stream is transformed into a confined vortex from which centrifugal forces tend to drive the suspended particles to the wall of of the cyclone body. It consists of vertically placed cylinders which has an inverted cone attached to its base. The particulate-laden gas stream enters tangentially at the inlet point into the cylinder. The outlet pipe for the purified gas is a central cylindrical opening at the top. The dust particulates are collected at the bottom in a storage hopper. The gas path generally follows a double vortex (Tse Hung,2012). The gas is first allowed to flow through a light circular spiral which produces centrifugal force on the suspended particles which in turn are forced to move upwards at the central portion of the cyclone. Because of inertia, the dust particles tend to settle on the surface of the cyclone wall, from where they are collected in receivers (Sharma,2007).

The collection efficiency of cyclones varies as a function of particle size and cyclone design. Cyclones are generally sized from the diameter of the cylinder (Mudakavi,2010). Cyclone efficiency generally increases with particle size and/or density, inlet duct velocity, cyclone body length, number of
