Product Code
12" dia sieves
Standards
ASTM E11; AASHTO M 92
Sieves are utilized in a variety of sieve testing applications, including soil sampling and classification, as well as powdered and granular materials. 12" sieves are specialized tools for effective separation of materials on the basis of particle size. Since they have a diameter of 12 inches, they are larger than most common standard sieves thus useful in big volumes of material handling. They are very integral in construction, agriculture, and laboratories, therefore very important.
The mesh or perforated surface of a 12" sieve will have an opening which allows the passage of smaller particles and retains the bigger particles. Such features are important so that precise results in sifting duties are achieved. For instance, aggregate sizes may be separated easily by using the 12" sieves in concrete ready mix products so as to result in desirable standards in the final product.
On comparing the 12" sieves to a slightly smaller size, say 8", the increased diameter would imply higher throughput. You could sift so much material at one go making it really useful for time-saving for professional as well as for DIY use. However, this increased size may also double the space you use for it and keep
Woven Wire Cloth and Perforated Plate Sieves are available in frame diameters of 8" dia (200 mm) and 12" dia (300 mm), with nominal aperture sizes suited for a variety of applications and requirements.
Sieves are made entirely of stainless steel.
How to Use 12" Sieves Effectively
Use 12" sieves effectively in order to enhance sifting. May use it in construction or on farms and even in laboratories. Here is how can do that step by step for to achieve optimal results with your 12" sieves.
Step 1: Gather Your Materials
Ensure that you have all you need:
- Your 12" sieve of the appropriate type for your task.
- The material you want to sift.
- A container for the sifted material.
- A spatula or scraper to collect materials, in case required.
Step 2: Prepare Your Work Area
Choose a flat, stable area for sifting. This will help to avoid spills and make work not stressful. In the case of fine materials, you should place a tray or pan under your sieve in order to catch the overflow.
Step 3: Load the Sieve
Load all the material, into the middle of the sieve with caution, because you should not load the sieve. In fact, overloading could potentially lead to uneven sifting and reduce the process effectiveness. A guideline for filling the sieve is to fill it up to half its capacity.
Step 4: Begin Sifting
The following are a few methods you may use in sifting effectively:
- Shaking: Use the ends of the sieve to hold it and gently shake it back and forth. This motion is used to let the smaller particles fall through the screen. In this way, the coarser will be located on top
- Tapping: Working with denser materials, tapping on the sides of the sieve may dislodge particles that are lodged in the mesh.
- Rotation: The other use of the sieve is in turning in a circular motion that allows the even spread of the material and improves sifting.
Step 5: Observe and Adjust
As you filter, take a minute to consider the results. If you find too many bigger particles flowing through, you may need to change your approach or use a sieve with a different mesh size.
Step 6: Collect the Sifted Material
Once you have sifted, take out the sieve carefully, and collect the sifted material in the container at the bottom. You can run a spatula on the sieve to scrape off particles left on it if necessary.
Step 7: Clean the Sieve
Clean your 8'' sieve after each use to keep it performing at its best. Here are some guidelines:
- For metal sieves, clean with warm soapy water and soft brush. Avoid abrasive material that may leave scratch marks on the surface.
- For plastic sieves, a soap and water wash is normally enough.
- Let it dry completely before you put it away not to rust or become moldy.
