CHAPTER ONE

INTRODUCTION

1.1 Background of the Study

Industrial mixers are essential tools in various manufacturing processes, providing efficient blending and homogenization of materials. The construction of an industrial mixer involves several engineering principles, including mechanics, thermodynamics, and material science. In industrial settings, mixers are used to combine raw materials such as powders, liquids, and pastes to achieve a uniform product. The performance of these mixers is crucial for ensuring product consistency, quality, and efficiency. This study focuses on the design and construction of an industrial mixer, examining its components, functionality, and the impact of various design parameters on performance.
