Soil Test Sieve

What is Soil Test Sieve?

Soil Test Sieve, also known as standard Soil Test Sieve, is a sieve used for soil testing and filtration, mainly used to separate soil of different fineness, suitable for soil nitrogen content determination, soil potassium content determination, soil carbonate determination, etc. For soil screening in various experiments, the sieve frame and screen are made of 304 stainless steel, which is not easy to rust and easy to clean. Different fineness of soil can speed up the operation steps in the laboratory.

Soil test Sieve is a special equipment for separating and sieving the residual plants and soil. After the experiment, the soil can be submerged, and the residual plants can be left on the top. The soil detection results obtained in this way are much more accurate. Use a soil sieve to remove The residual plants in the soil are convenient for measuring various data contents in the soil in the following work, and the residual plants in the soil can be extracted separately, so that the proportion of the plant debris in the soil can be simply calculated, from From the perspective of organic fertilizers, the degree of emeraldness of the soil is judged.

Soil test Sieve saves a lot of time for people in the process of soil experiments, and makes the experimental results more accurate. Its application is of great significance to agricultural experiments.

Applications of Soil Test Sieve

Soil Test Sieve is suitable for analyzing soil with a particle size greater than 0.074mm, and can separate soils of different finenesses. It can be used for soil nitrogen content determination, soil potassium content determination, soil carbonate determination, soil sieving, sand, cement, coarse sand , soil, stones and other experiments.

How Soil Test Sieve works?

Put the Soil Test Sieve frame on the test sieve machine, turn on the power, and use the vibration motor as the vibration source. The vibration of the vibration motor will drive the vibration of the base of the sieve machine, and then conduct it to the soil sieve placed on the base through the base, so that the soil sieve smaller than the soil sieve The material particles in the mesh of the sieve surface are screened into the soil sieve of the lower layer, so that only materials with the same particle size are left in each layer of soil sieve. To achieve the separation of different particle sizes and to determine the particle size composition of this material. The purpose of making the materials in the soil sieve can be effectively screened, graded and filtered.

Soil Test Sieve Instructions for Use

1. Coarse sieves commonly used in geotechnical tests 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 number of shaking is 100~200 times/min, and the number of slaps is 50~70 times/min;

Soil Test Sieve Test Method

1. From the air-dried loose soil samples, the soil was taken by quartering.

2. Pass the sample through a 2mm sieve, and weigh the soil mass above and below the sieve, respectively. Take the soil above the 2mm sieve and pour it into the upper sieve of the stacked coarse sieve, and pour the soil under the 2mm sieve into the upper sieve of the fine sieve stacked in sequence (the analysis sieves are stacked from top to bottom, from large to small) . Use a sieve shaker to fully sieve and analyze until the diameter of the soil particles on each sieve is larger than the sieve aperture, generally shake the sieve for 15~30min;

3. Starting from the large aperture sieve, remove each sieve in sequence, and weigh the soil left on each sieve separately, accurate to 0.1g. The difference between the sum of the soil mass on each sieve and the total soil mass shall not be greater than 1% of the total soil mass;

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

Soil particle size (mm)	＜2mm	＜10mm	＜20mm	＜40mm	＞40mm
Sampling mass (g)	100-300g	300-900g	1000-2000g	2000-4000g	Above 4000g
