Types Of Sifting Screens To Choose From

If you are looking for small minerals in dirt, sand or gravel, you will need to use a sifting screen. This is very useful if you are working in a garden and want to remove stones and other debris more rapidly in a garden. They are also useful if you are engaging in archaeology. You will likely need more than one type of sifting screen, since no one screen works under all circumstances. To catch minerals in the screen, the openings in the screen must be smaller than the size of the minerals.

The Composition of the Screens

The most durable screens are those that are made out of perforated metal. This is a sheet metal that has had holes punched through it. Other alternatives include wire mesh screens made out of one of several metal types. The frame is usually made out of wood that needs to be water-sealed to protect it from moisture that would otherwise cause it to rot.

Portable Screens

When engaged in back country surveying, consider purchasing a backpack screen. A removable nylon mesh makes it easier to carry the sifter and allows for you to carry other items with it. Once you have arrived at the site, remove the sifter from the carrying case and the remove the additional items.

Small and Large Sifters

Hand sifters are generally smaller and come with handles on each side that make the sifters easier to use and also protect the user’s hands from the minerals. On the other hand, if the goal is to sift through as much material as possible in a short time frame, the two-person sifters are idea. One person holds each end and drags the sifter upward to remove minerals and other debris.

Tilting Sifters

The materials are removed by shaking the sifter so that the gravel, dirt and sand can fall underneath. Some sifters are able to tilt so that it is easy to allow the gravel to slide from one side to another. There are also rocking sifters that come with a front lateral dowel and an adjustable height.

Double-Decker Sifters

If you need to sift through two different-sized meshes, you should get a double-decker screen. This option has two sifting screens, with one clamped on top of the other. First, the material that is captured on the top screen is collected. Then, the material caught by the bottom screen is collected.
