Product overview 

Standard soil screen is the screen that filters the soil. It is widely used in the classification, screening, analysis and testing of samples in various laboratories. Equipped with automatic laboratory shaker with higher efficiency and safety.

Product usage instruction

1.The coarse screen commonly used in civil engineering experiment is the circle hole, there has different size of bore diameters, like100,80,60,40,20,10,5,2mm, and its effective diameters is 2.0,1.0,0.5,0.25,0.10,0.075mm. The classification of screen hole in different countries and departments is also different.

2.Analytical balance. The analytical balance is pided into two types according to the range and accuracy of weighing, (1)weight 10kg, feeling1g, (2) weight 1000g,feeling0.1g.

3.Sieve machine, standard shaking screen machine in the horizontal direction shaking vibration, beating in the vertical direction. The shaking frequency is 100~200 times per minute, the bits is 50~70 times per minute.

Product test method

1.From the  air - dried loose soil, the soil was taken in quarters. Pass the solids sample through a 2mm screen and measure the quality of the soil on and under the screen.

2. Pass the sample through a 2mm sieve to measure the quality of the soil above and below the sieve respectively. Pour the soil on the 2mm sieve into the upper layer of the coarse sieve that has been successively stacked, and the soil on the 2mm sieve into the upper layer of the fine sieve that has been successively stacked (the size of the sieve from the top to the bottom is analyzed to be from the top to the small size). Use shaking sieve machine to fully screen and analyze the soil particles on each sieve until the diameter is larger than the diameter of the sieve hole. Generally, shake sieve for 15~30min.

3.Starting from the maximum aperture sieve, remove each sieve in sequence, and weigh the soil left on each sieve to 0.1g accurately. The difference between the sum of the soil masses on each sieve and the total soil masses shall not be greater than l % of the total soil masses.

4. Calculate the content of grain size and cumulative content and draw the grading curve to obtain the characteristic particle size, then analyze the grading of soil and choose name according to the specification.
