how to make a stone crushers

Building a stone crusher involves designing and constructing a machine that can reduce large rocks into smaller gravel, sand, or rock dust. Here’s a step-by-step guide on how to make a simple stone crusher:

—

Materials & Tools Needed:
1. Heavy-duty steel frame (for the crusher body)
2. Jaw plates or impact hammers (hardened steel for crushing)
3. Bearings & shafts (to support moving parts)
4. Electric motor or diesel engine (for power)
5. Pulleys & belts (for power transmission)
6. Flywheel (to maintain momentum)
7. Bolts, nuts, and welding equipment
8. Angle grinder, drill, and cutting tools
9. Safety gear (gloves, goggles, welding mask)

Steps to Build a Stone Crusher:

# 1. Design the Crusher
– Decide whether you want a:
– Jaw Crusher (compression crushing)
– Impact Crusher (hammer-based crushing)
– Roll Crusher (for softer stones)
– Sketch a design with dimensions for the frame, crushing chamber, and moving parts.

# 2. Build the Frame
– Weld a sturdy steel frame to hold all components.
– Ensure it can handle vibrations and heavy loads.

# 3. Install the Crushing Mechanism
– For a jaw crusher:
– Fix one jaw plate stationary and another movable on an eccentric shaft.
– The moving jaw crushes stone against the fixed jaw.
– For an impact crusher:
– Mount hammers/beaters on a rotating rotor that smashes stones against breaker plates.

# 4. Set Up Power Transmission
– Connect the motor/engine to the crusher using pulleys and belts.
– Ensure proper speed reduction if needed (crushing requires high torque).

# 5. Add Discharge System
– Install an adjustable gap mechanism to control output size.
– Include a chute to direct crushed material into a collection bin.

# 6. Test & Adjust
– Run the crusher with small stones first.
– Check for jams, vibrations, or wear on components.
– Adjust jaw/impact plate gaps for desired output size.

Safety Considerations:
– Wear protective gear when welding or
