I built a sifting table with the following characteristics:
The table is built at a slant.
The table top is 6-feet by 2-feet.
The table top allows for the insertion of different sifting frames; window screen, 1/8" hardware cloth, 5-mesh hardware cloth, 1/4" hardware cloth, 1/2" hardware cloth
The table stands just over 2 feet high at the low end and nearly 4 feet high at the high end.
The low end of the table has no end wall to allow sifted material to roll off into a collection bucket.
I use utility tubs from Lowes (larger than masonry tubs) beneath the table to catch what falls through.
I mounted a bench grinder onto the high end of the table for vibration.
The table is made of 2x4 and 1x6 lumber.
The legs can be removed for storage.
As for the bench grinder, I broke off a portion of one of the grinding wheels. This causes serious vibration and gets the material moving! I bought a variable speed router control from Harbor Freight Tools to control the speed, and thus the vibration, of the table.
The wood was cut using a chop saw. Most of the cuts were standard left-right miter cuts for the slope of the table. However, the diagonal supports for the legs also required a side-to-side angle to get everything lined up.
This table causes a great deal of noise, so I use it in the middle of the day. I use a general use dust respirator, the kind with removable side cartridges.
Window screen gets out the dust. Screens up to 1/4-inch give me specific use sifting.
I use pine bark mulch marketed as soil conditioner as my organic component. It provides a good quantity of the right sized particles, but it can have some larger strips in there as well. After sifting the smaller particles out, I put on the 1/2" screen and hand sift (no vibration) the remaining pine bark by just rubbing it through the screen. The longer strips and sticks stay on top for me to remove.
I buy haydite 2-cubic yards at a time and store it in 44-gallon Rubbermaid Brute trash cans. I can sift an entire can of haydite in less than an hour, and that includes setting up the table and sifting the haydite twice.
I'll be purchasing another 2-yards of haydite soon. My goal is to sift it all BEFORE is store it. I've been lazy in the past and only sifted one 44-gallon can when I ran out of sifted material. I'll have to make note of how long it takes me to sift that much material, if the bearings in the bench grinder hold up, and if the neighbors call the cops on me for making an all-day racket-party.
I'll have to post photos as well.
