ABSTRACT
Industrial mixer is equipment designed to carryout operation involved the combination of two or more substance to achieve a uniform product. The method of fabrication of this mixer involves a preliminary computation of the dimensions of the standard which they will be used in marketing out cutting, out to sizes rolling or folding, welding, body filling and painting to prevent corrosion attack. The result obtained after the process undergoes was a batch operation industrial mixer which can contain about 56.12 liters with statistics of the vessel being 410mm by diameter and 425mm by height. The width of the baffle is 35mm and length of impeller 150mm. Although, the result obtained (mixer) was excellent, but do not have up to 100% mixing efficiency due to some factors during the fabrication process such as error in cutting operation, low quality material etc. Cost of production was estimated up to thirty thousand naira when summed up, i.e the material cost, labour cost and expenses.

CHAPTER ONE
1.0 INTRODUCTION
Mixers are equipments used to prepare a uniform combination of two or more substances. It is used in mixing operation which is very common operation carried out in chemical and process industrial. It may involve the mixing of solids, liquids or gases in any possible combination involving two or more of the above.
Mixing operation is an operation that is performed in order to bring about homogeneity or reduce degree of non-uniformity of a system. These are achieved to another or from one part of the region to another part of the system region, this intend to effect distribution, intermingling and homogeneity of matter.
The material fed to mixer may be low or moderate viscosity liquids, highly viscous Newtonian or non-Newtonian liquid plastic and deformed solids like rubber or dry free flowing powders and the uniform combination of two or more material from a mixer may be either homogenous or heterogeneous.
Component of mixer
The component of mixer include
(a) The shaft
(b) The impellers
(c) The vessel or tank
The Shafts: These are the connecting rods that hold electric motor with a belt. The diameter of the shaft varies with the point of attachment in the driving motor and its length of the shaft varies with the height of the vessel. Shafts are used to transmit an induced motion from the driving motor to the impeller arrangement.
Also they are used in the location of impeller in an agitated vessel.
