half inch mining screen

How to Build a Home Sand and Gravel Screen | Hunker

Step 2. Cut various grades of steel mesh to fit each box. Use the widest opening in the steel mesh of about 3/4 inch to sift out the larger gravel stones. Half-inch steel mesh will give you a smaller grade of gravel while 1/4-inch screen separates the smaller particles of stone. Build a final screen with 1/8-inch mesh if you want fine sand.
