Automated Plastic Sand Mixer

In Zimbabwe, improper waste disposal is causing environmental issues like land pollution and blocked drainage. Most organizations manually mix plastic and sand to produce paste, which is time-consuming and reduces production rates. The aim is to design an automated plastic and sand mixer to produce paste for bricks and tiles more efficiently. Objectives are to design the mixer, select heat-resistant materials, integrate an electronic control circuit, and ensure safety. Benefits include improved productivity, quality, and health conditions for workers compared to manual mixing. The scope is mixing and heating plastic and sand granules to make paste.

CHAPTER 1

1.0 Background to the problem

In Zimbabwe majority of the populous is improperly disposing their waste materials especially
plastics mainly due to the lack of proper waste collection system and also ignoance. This
negatively affects the environment by that there is land pollution. This results in the blockage of
drainage systems.Some of the waste materials are non bio degradable which results in untorward
garbage piling in different corners across the city.

1.1Problem statement

In Zimbabwe most organisations produce paste by manually mixing plasting and sand which is
time consuming and affects the rate of production.
1.2Aim

To design an automated sand and plastic mixer to produce paste for making eg bricks and tiles
etc.

1.3Objectives

To design the plastic sand mixer


To determine the materials suitable for the high temperatures
To intergrate an electronic circuit to automate the design
To ensure product is safe to use

1.4Justification

An automated plastic sand mixer improves productivity by producing more paste in a


given period of time compared to the manual worker
An automated plastic sand mixer is more effective compared to the manual worker for it
is not affected by fatigue and does not need breaks.
There is improved quality of the paste produced by the machine.
Commercialization of this machine promotes indigenization in Zimbabwe for there is no
need to import the produce hence it makes it more affordable.
Since this machine requires any type of plastic, the collection of plastics from the streets
reduces pollution.
The use of the machine it reduces the health hazards of the workers by that they are not
directly exposed to the fumes and heat of the mixing sand and plastic and also no long
term skeletal disorders.
The project benefits the researchers as they gain the technical ability to properly design a
working prototype and also improves on teamwork.

1.5Scope
The project focuses on mixing granules of plastic and sand and then heating the mixture to
produce the paste.
