Material Crusher Machine: A Review

Abstract

Material crushers are essential machines used in construction, mining, and quarry industries to reduce large rocks into smaller aggregates. This paper presents the design and fabrication of a small-scale material crusher model intended for laboratory and small industrial applications. The study discusses the working mechanism, major components, and design considerations such as material strength, flywheel energy storage, and crushing mechanism. Computer Aided Design (CAD) tools are used to develop the model and visualize component assembly. The fabricated machine is designed to be efficient, durable, and economical. The proposed design demonstrates that how Mechanical principles can be applied to develop a reliable Crushing Machine capable of handling moderate crushing loads while maintaining operational simplicity and safety.

Introduction

A material crusher is a mechanical machine used to break large rocks into smaller particles like gravel, sand, or dust, which are widely used in construction, mining, and road building. Due to increasing infrastructure demand, there is a need for efficient and low-cost crushing systems. This project focuses on designing and fabricating a simple material crusher that demonstrates effective crushing using basic mechanical principles such as compression and impact.

The main objectives include reducing rock size, separating useful minerals, preparing materials for further processing, recycling construction waste, and improving handling efficiency and safety.

The literature review shows that crusher design is based on mechanical engineering principles such as stress analysis, fatigue strength, kinematics, and material selection. Researchers emphasize the importance of energy efficiency, durability, and proper design of components like shafts, flywheels, and jaw plates. Studies also highlight the use of CAD tools and simulation software to improve performance and reduce design errors before fabrication.

The crusher consists of key components including a frame, fixed and movable jaw plates, toggle plate, eccentric shaft, flywheel, hopper, and electric motor. These parts work together to apply compressive force and break stones into smaller sizes.

CAD modeling is used to design and assemble the machine virtually, allowing analysis of alignment, strength, and structural stability before manufacturing. Design calculations such as torque and flywheel energy storage ensure safe and efficient operation. For example, using a 2 HP motor at 1440 RPM, the crusher shaft torque is calculated based on reduced operating speed.

Conclusion

The design and fabrication of a Material Crusher demonstrate the application of mechanical engineering principles in developing industrial machines. 1) The proposed crusher model provides an efficient solution for reducing large stones into smaller aggregates. 2) Proper design, material selection, and fabrication techniques ensure reliability and durability of the machine. 3) Future improvements may include automation and improved wear?resistant materials to increase productivity and operational life.
