ORE CRUSHER USING ENGINE

### **Short Description of the Machine** The **Automated Counter-Rotating Roller Crusher for Gold Ore** is a laboratory-scale prototype designed to crush gold ore into smaller, uniform particles for further mineral processing. The machine operates using two counter-rotating grooved rollers that grip, compress, and fracture the ore through compressive forces. It is powered by a **3 HP electric motor** connected to a **15:1 gearbox**, which reduces the motor speed and increases torque to provide sufficient crushing force. The machine consists of a **hopper**, **counter-rotating rollers**, **roller shafts**, **spur gears**, **bearings**, **belt and pulley drive system**, **supporting frame**, **collection tray**, and an **Arduino-based control system** for automated operation. The frame is fabricated from mild steel, while the rollers and shafts are manufactured from high-strength steel to withstand wear and crushing loads. The prototype is designed to process **50–100 kg of gold ore per hour**, accepting a maximum feed size of **80 mm** and producing a final particle size of **5–15 mm**. Its compact design, simple construction, and automated control make it suitable for laboratory experiments, educational purposes, and small-scale mining applications. ### **Main Specifications** * **Machine Type:** Automated Counter-Rotating Roller Crusher * **Capacity:** 50–100 kg/h * **Maximum Feed Size:** 80 mm * **Product Size:** 5–15 mm * **Roller Diameter:** 100 mm * **Roller Length:** 200 mm * **Motor Power:** 3 HP (2.2 kW) * **Gearbox Ratio:** 15:1 * **Roller Speed:** 96 rpm * **Control System:** Arduino-based Automation * **Frame Material:** Mild Steel * **Roller Material:** EN24 Steel * **Overall Dimensions:** 1000 × 600 × 1150 mm (L × W × H) * **Approximate Machine Weight:** 125 kg This prototype provides an efficient, reliable, and cost-effective solution for laboratory-scale gold ore crushing while demonstrating the application of mechanical design, power transmission, an
