CONSTRUCTION OF A PILOT MOTORISED MIXER

ABSTRACT

A motorized mixer of 200 liters capacity was constructed to have the capability of mixing 200 liters of fluid during operation.

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
