DESIGN AND CONSTRUCTION OF A SELF FEEDING CASSAVA GRATING MACHINE

This project seek to modify the existing cassava grating machine to make it to be self-feeding in operation, to make the operation of the machine easier, safer The existing processing techniques used in the production of cassava starch and cassava dough leaves much to be desired. There are difficulties in the grating of the cassava dough, since the conventional methods available is time consuming and labour intensive. In the modified design, two side hopper, belt drives, gears and pulley will...

Development of Autonomous Lawn Mower from Locally Sourced Materials

A lawnmower is a machine that uses a revolving blade or blades to cut a lawn grass. Many designs have been made, each suited to a particular purpose. Manual grass cutter has environmental issues regarding pollution's and also require the need of man power to operate and has a great maintenance to its engine. This robot is design to be environment friendly and operated by a rechargeable battery and can be describe as an intelligent robot because the micro-controller receives information from s...

Purification of Water Using a Plastic Bio-Sand Filter

Plastic bio-sand filter is a prototype of a slow sand filter which purifies water using sand and gravels of specific sizes of (0.36mm, 2.36mm, 6.35mm), this filter has been designed and constructed to evaluate its performance using raw water from fishpond at faculty of Engineering, Ahmadu Bello University Zaria and to remove pathogenic organisms present in the water. The filter is composed of a lid which covers the whole filter from the entrance of debris or contaminants, a perforated pl...

CHARACTERIZATION OF NON-EDIBLE OIL FROM WASTE PLANT MATERIALS FOR BIOIDIESEL PRODUCTION

Oil obtained from orange peels and velvet tamarind nut by solvent extraction (n-hexane and acetone) using the soxhlet extractor were investigated as feedstock’s to determine some of the suitable parameters such as iodine value, saponification value, specific gravity, density, acid value and free fatty acid value, and their percentage yield that are suitable for biodiesel production. The density of orange and tamarind oil were found to be 0.9326g/cm3 and 0.8541g/cm3 respectively, their acid ...

DEVELOPMENT OF A SOLAR POWERED CAR

ABSTRACT: This project work is on the development of a solar powered car. It involves the design and fabrication of a solar powered car with a carrying capacity of two and a maximum speed of 30 km/hr, which runs entirely on a stand-alone solar system. The car is a unique prototype sedan car. It is designed with dimensions of 3 meters’ x 1.6 meters'. The maximum load carrying capacity of the vehicle is 700 kg and it requires a driving force of about 4.3 kW. The solar car uses a clean engine...

Design and fabrication of a PET (Polyethylene terephthalate) crushing machine.

Due to the need for recycling Polyethylene terephthalate (PET or PETE) materials, especially bottles because of its various uses and applications, it was necessary that a locally made machine for crushing and shredding the PET materials was fabricated. The crushing process is necessary so as to aid the transportation and workability of the material. This is a paper work for the activities carried out in the design, construction and fabrication processes.

Maintenance, supervision and inspection at a water treatment plant.

Clean and potable water is one of the basic infrastructures any responsible government needs to provide for its people. I was part of a team of competent engineers that carried out inspection, repair and maintenance of facilities at a water treatment plant. This is a paper work for different maintenance and supervision activities carried out at the water treatment plant. I employed my engineering skills in inspection, maintenance and supervision of the machines, making sure that they are up a...

DESIGN OF SEDIMENTATION TANK TO RESUSCITATE PHYTOREMEDIATION IN OVERLOADED OBAFEMI AWOLOWO SEWAGE TREATMENT PLANT

The discharge of raw sewage or improperly treated sewage into water bodies has always had a threatening effect on aquatic lives and that of human that uses the water on the downstream. Such is the case of Awba Lake which is currently being polluted by effluents from Obafemi Awolowo sewage treatment plant. The treatment plant is currently overloaded and macrophyte (water hyacinth) used for phytoremediation in the treatment plant can no longer survive under such high organic condition. This pro...

Comparative Assessment of Rice Husk Ash, Powdered Glass and Cement as Lateritic Soil Stabilizers

COMPARATIVE ASSESSMENT OF RICE HUSK ASH, POWDERED GLASS AND CEMENT AS LATERITIC SOIL STABILIZERS. ABSTRACT This paper compares the stabilizing effects of three different materials, namely: rice husk ash, powdered glass, and cement on the properties of lateritic soil. The basic properties of the lateritic soil were first obtained through colour, moisture content determination, specific gravity, particle size distribution and Atterberg limits tests. Each of the stabilizing materials was th...

Design and Fabrication of journal Bearing Testing Rig

ABSTRACT This project work deals with the design and fabrication of a suitable journal bearing test apparatus which can help in visualizing the behavior of journal bearing and its characteristics, and in determining the bearing parameters such as load bearing capacity, maximum oil film temperature, viscosity of lubricant, oil film pressure, and coefficient of friction based on experimental analysis. The work covers the design of a test apparatus which can be utilized to check the behavior of...

A Model for Economic Production in Manufacturing Industries Under Unstable Power Supply.

The research study presents the development of a model for Energy cost in manufacturing industries under irregular power supply. The work considers power consumption in the operation of production machines, hence cost incurred in running of these machines Parameters such as machine types for production, numbers of machine types for production and power ratings of machines for production were also considered in the development of the model The study employs linear programming approach in formu...

Production of Kenaf Fibre Reinforced Polyethylene Composite for Ballistic Protection

Kenaf reinforced polyethylene composites for ballistic protection was produced in this work. The samples of alkaline treated and silane-coupled non-woven matted kenaf fibers were cut to the required dimensions and oriented vertically and horizontally in combinations with a virgin high density polyethylene (VHDPE). The composite panels were produced using Box-Behnken 3-variables settings. The following factors settings were used (molding temperature: 160 0C to 200 0C; molding time: 60 minute...
