Sifting, Sieves and Sizing

This is one of those Ebay sales I just could not pass up. An old shaker for the analysis of soil samples. This is a very crude version of a shaker I used many years ago to check the grind of spices.

The key to sizing materials is not so much the shaker, but the sieves. There are brass pans with very exacting sized screen across the bottoms. Here you can see some of the large openings.

The pans are stacked in descending order of opening size.

The pans are then clamped into the shaker with a solid pan at the bottom of the stack. This is something best done outside as much dust can become airborne with the shacking process. A good dust mask is also a very good idea.

For this demo, I am sizing a bag of lime from a garden store. The product is slowly poured into the top pan while the stack is being shaken but the motor.

When the pans are unstaked, each contains the particles small enough to pass through the upper sieves, but too large to pass through the screen of the pan itself.

The different grades of material can then be stored in some convenient containers. Careful labeling is needed to keep track of the work of sizing the material.

This bag contained a few "clunkers", large lumps of material, that might make good terrain items just as they are.

To see how the sifting of the matterials effects their use, check out Sand, Coffeeand Tea.
