Building a stone crusher requires mechanical knowledge, materials, and tools. Below is a basic guide on how to make a small-scale manual stone crusher (for experimental or small-scale crushing purposes). For industrial use, professional machinery is required.

Materials Needed:
1. Heavy-duty steel plates (for jaws and frame)
2. Steel bars or rods (for reinforcement)
3. Bearings (to allow smooth movement of the crushing mechanism)
4. Bolts, nuts, and washers (for assembly)
5. Welding machine & electrodes (for fabrication)
6. Angle grinder & drill machine (for cutting and drilling holes)
7. Pivot mechanism or hinge (to allow jaw movement)
8. Handle or lever system (for manual operation)

” /> Steps to Build a Simple Manual Stone Crusher:
# 1. Design the Crusher
– Decide between a jaw crusher, hammer mill, or roller crusher. The simplest is a jaw crusher.
– Sketch the design with two jaws: one fixed and one movable.
# 2. Build the Frame
– Cut steel plates into two side panels and a base.
– Weld them together to form a sturdy rectangular frame.
# 3. Create the Crushing Jaws
– Cut two thick steel plates into rectangular shapes (one fixed, one movable).
– Weld the fixed jaw to the frame at an angle (~20°–30°).
– Attach the movable jaw to a pivot point using heavy-duty hinges or bearings.
# 4. Add a Lever Mechanism
– Attach a long steel bar as a lever arm to the movable jaw.
– Use bolts or welding to secure it firmly.
– A spring can be added to help return the jaw to its open position.
# 5. Adjustable Gap for Crushing Size
– Install an adjustable bolt or spacer at the bottom of the movable jaw to control how fine the crushed stones will be.
# 6. Test & Operate
– Place stones between the jaws.
– Apply force on the lever arm to crush them manually.
– Adjust settings for desired output size.

Alternative: Motorized Stone Crusher
For an automated version:
1. Replace manual lever with an electric motor.
2. Use belts/pulleys or gears for power transmission.
3. Add flywheels for
