Soil Sieve

Method of Using Soil Sieve

1. Take soil from air-dried loose soil samples by quartering. The quantity of soil is carried out according to the following figure in the table.

2. The sample was screened by 2mm, and the soil quality on and under the screen was respectively weighed out. Pour the soil on the 2mm screen into the upper layer of the coarse screen stacked in turn, and pour the soil under the 2mm screen into the upper layer of the fine screen stacked in turn (analysis screen from top to bottom aperture large to small stack). The sieve shaker is used to fully sieve out until the soil particle diameter on each sieve is greater than the mesh pore diameter, generally shaking the sieve for 15~30min;

3. Starting from large aperture sieve, each sieve will be removed in sequence, and the soil left on each sieve will be weighed respectively, accurate to 0.1g. The difference between the sum of the soil mass on each screen and the total soil mass shall not be greater than l% of the total soil mass.

4. Calculate the content of grain group and cumulative content, draw the gradation curve, get the characteristic particle size, analyze the gradation of soil, and name it according to the specification.

Soil Sieve Instructions for Use

1. Coarse sieves commonly used in standard soil sieves are generally round holes with apertures of 100, 80, 60, 40, 20, 10, 5, 2mm; fine sieves are generally square holes with equivalent apertures of 2.0, 1.0, 0.5, 0.25, 0.10, 0.075mm. There are some differences in the pore size classification of analytical sieves used in different countries and departments;

2. Analytical balance, analytical balance needs two types according to the weighing range and accuracy: (1) weighing 10kg, with a sense of 1g, (2) weighing 1000g, with a sense of 0.1g;

3. Shaker, the specification stipulates that the shaker can shake in the horizontal direction and slap in the vertical direction. The shaking frequency is 100~200 times/min, and the slapping frequency is 50~70 times/min.

How to make a soil sieve

Add handles or grips to the frame for easier handling.

Consider painting or waterproofing the frame for durability.

Place the sieve over a container or bin to collect sifted soil.

Pour soil onto the sieve and gently shake or agitate it to allow fine particles to pass through the mesh.

Proven solutions for our wide range of products

How soil sieves are used in different industries:

Agricultural Research

A research facility uses soil sieves to analyze soil samples from different regions to determine their nutrient content and suitability for growing specific crops. Soil sieving helps provide accurate particle size analysis and identifies any soil health issues that may affect crop growth.

Soil Remediation

An environmental consulting firm uses a soil sieve to analyze soil samples from a contaminated site to determine the particle size distribution and composition of the soil. Soil sieving helps determine the presence of heavy metals and other contaminants, which informs remediation strategies.

Building Material Analysis

A construction company uses soil sieves to analyze sand samples from a quarry to determine particle size distribution and suitability for concrete production. Soil sifters help determine the proper sand size for a specific project and ensure the quality of building materials.

Gardening

Greenhouses use soil sieves to analyze soil samples from different pots to determine nutrient content and suitability for growing specific plants. Soil sieving helps provide accurate particle size analysis and identifies any soil health issues that may be affecting plant growth.

Department of Agriculture Soil Texture Grade (If you need a more accurate definition of your soil's texture grade, you should take a disturbed soil sample to a testing lab to quantify particle size.):
