    Design and production specifications of machine for wood cement composite boards production
    (2013) Omoniyi T.E.; Akinyemi B.A.; Olayiwola H.O.
    Manual method of producing wood cement composites (WCCs) is time consuming, labour intensive and leads to inconsistent products. This paper reports the design and production specifications for a machine capable of automating the critical processes of mixing, blending, vibrating and compacting involved in WCC production for rural usage at a cottage level. It is a semi-continuous manually operated machine, made up of two broad units: the mixer and the former (conveyor cum press). The mixer is hand powered by a lever 500mm long at an average speed of 35rpm and has a capacity of 0.1514m3. The former is made up of rollers interconnected with chain drives and a freely rotating press roll. It is powered by a manually operated pulley system at an average speed of 4rpm. The mixer can save up to 52% of the total time required to achieve homogenous mix while the former can also reduce time required for board formation by 50%. The machine has an overall capacity of producing 30 Nos. of 12.5mm × 570mm × 570mm boards.
