CONSTRUCTION OF A PILOT MOTORISED MIXER A REPORT PRESENTED TO THE DEPARTMENT OF CHEMICAL ENGINEERING OF THE INSTITUTE OF MANAGEMENT AND TECHNOLOGY, ENUGU
ABSTRACT
The construction of the mixer involves the preliminary measures and calculations on the surface area of the metal sheet. Some basic workshop practices was carried out during the construction such as the marking out of the metal sheet, cutting of different sizes of the sheet, welding of the prints, assembling of the components parts and painting of the equipment.
The material used in the construction of the mixer is mainly of mid steel. The mild steel was used for the construction due to its quality cost availability and characteristics.
The cost of constructing the motorized mixer was cheep due to the choice of material selected for the constructional project and it was finally painted with aluminum paint to protect it form corrosion.
The material dimension used in construction of the motorized mixer is as follows:
Length of vessel                                                         700mm
Diameter of vessel                                                     600mm
Length of shaft                                              800mm
Surface area of plastic vessel             1320000mm
Electric motor rating                          733.3v 50/60HZ, 3728.5 watt
7000r pm
