How to separate clay and sand in the soil

The most common method is to use gauze and water to separate the sand and clay from the soil. Clay can't be filtered out.

It is to add a mixture of sand and clay to the water, fully stir it into a suspension, filter it with a gauze mesh, so that the coarser sand remains on the gauze mesh, and the fine clay powder leaks down (the solid on the gauze can be repeatedly rinsed to make the clay completely leak down), and then the clay in the mud water is filtered out with filter paper and dried separately; The range of sand is very broad, and sand in the broad sense includes clay; What can be filtered down is clay, and generally sand and gravel cannot be filtered down.

Clay soil is a clayey soil with few sand grains, and it is not easy for water to pass through it to have good plasticity. Clays in general are formed by the weathering of silicate minerals on the earth's surface. Generally, weathered in situ, the particles are larger and the composition is close to the original stone, which is called primary clay or primary clay.

Experimental analysis: Pour two-thirds of the water into the beaker, slowly pour the soil into the water, gently stir it in one direction with a glass rod, and let it stand for half an hour before observing.

Experimental Phenomenon: The soil is divided into two layers.

Experimental conclusion: the upper layer of soil particles is smaller, it is clay; The particles of the lower layer are larger, it is sand.

After adding water, filter it with gauze, the clay can be filtered, but the sand cannot.

(1) Sandy soil is a kind of soil dominated by sand particles, and sand particles of various sizes can be clearly seen. The sediment content can reach 85% to 100%, while the fine soil content accounts for only 0 15%. The sandy soil is aerated and permeable, but it has few nutrients, poor fertility and is susceptible to drought.

It can be mixed with clay soil to improve, and clay manure and pond mud can be applied at ordinary times, and chemical fertilizers should not be applied more. The use of phosphate fertilizers and trace elements on sandy soil is very effective. (2) Sandy loam soil is a kind of soil with more sand particles and less fine soil.

Its sand content can reach 55% 85%, and it can be spherical when wet, and the dry soil is easy to crush. This kind of soil is loose, aerative and permeable, not sticky or hard, suitable for farming, but poor fertilizer and water retention. When fertilizing, more sticky manure should be applied, and chemical fertilizer should be applied in accordance with the principle of "a small amount and many times", and it should be applied diligently and less to prevent fertilizer loss.

3) Loam: A kind of soil with good texture and suitable sandy clay content. Its characteristics are loose but not loose, sticky but not hard, not only breathable and permeable, but also water and fertilizer retention, high fertility, suitable for planting a variety of plants. Artificially formulated loam can be thoroughly mixed with 20% clay, 30% 40% silt, and 30% 40% sand.

4) The clay content of the clay reaches 45% 100%, of which the sand particles with a particle size of millimeters account for only 0 35%. Clay soil has high water and fertilizer retention capacity, and contains more nutrients required by plants, but it has poor aeration and water permeability, wet and clay, dry and hard, large soil blocks, and is not easy to cultivate. It should be improved by appropriately mixing sand and applying more organic fertilizers.

Sand, loam, and clay soils are divided according to the texture of the soil.

Sand: The sand content of sand is more than 50 and the clay content is less than 30. Therefore, the pores between its soil particles are large, the small pores are few, and the hairiness.

The action of the thin tube is weak, and the water retention is poor. However, the sand soil has good permeability and is not drought tolerant, and the soil microorganisms are dominant in aerobia. Due to its loose texture, it is easy to cultivate.

The organic matter of sandy soil decomposes quickly, accumulates less, and nutrients are easy to leach, resulting in a relatively poor variety of nutrients. Fertilization in sandy soil is effective, crops grow early and hair quickly, but there is no stamina, which often causes lack of fertilizer and early aging, low seed setting rate, and insufficient grains. This type of soil is neither fertiliser nor fertiliser-tolerant.

If you apply too much fertilizer at one time, it will not only cause loss and waste, but also cause crop one.

Time is crazy to grow. Therefore, it is necessary to pay attention to a small amount of fertilization, and apply more organic fertilizer and mud fertilizer.

Clay: its texture is heavy and clayey, poor tillage, lack of large pores between soil particles, so poor aeration and water permeability, neither drought tolerance, nor waterlogging tolerance, but its water retention and fertility are strong, fertilizer resistance, nutrients are not easy to leach, nutrient content is richer than sandy soil, organic matter decomposition is slow, humus is easy to accumulate. This.

Planting soil water is more and less gas, soil temperature change is small, soil is cold, good gas decomposition is not vigorous, nutrient decomposition and transformation is slow, fertilizer is late after fertilization, fertilizer has stamina, no small seedlings grow old seedlings, if excessive fertilization will cause crops to be greedy for green and late maturity in the later stage.

Loam: Loam is between sand and clay in nature, and its tillage and fertility are better. The contradiction between water and air is not so strong in this kind of soil, it is aeration and permeability, has moderate fertilizer supply and fertilizer retention capacity, drought and waterlogging resistance, strong stress resistance, wide adaptability, long tillage period, and is easy to cultivate into high-yield and stable-yield soil.

Supplement: Sandy soil has the least soil content and low viscosity, which is not suitable for the growth of most plants. The clay is sticky, there are few voids in the soil, and it is not easy to ventilate and leak, which is suitable for breeding. Loam soil is the best soil for the growth and contraction of plant roots, with high nutrient content and easy loosening.

Summary. Generally, only two types of equipment are used, the soil and sand are first screened with a high-frequency vibrating screen, and then cleaned with a wheel bucket sand washer, which can easily separate the soil and sand in two steps. Let's take a look at both devices.

1. High-frequency vibrating screen.

The last step of the machine-made sand production is to use the vibrating screen to screen it as the end, the soil and sand can be screened, the motor through the V-belt, drive the exciter spindle to rotate, due to the centrifugal inertia force of the unbalanced weight on the exciter, so that the screen box is vibrate.

2. Wheel bucket sand washing machine.

Under the tumbling of the wheel bucket, the sand and gravel remove the impurities covering the surface of the sand and gravel, and at the same time destroy the water vapor layer covering the sand particles, so as to facilitate dehydration; Then add water at the same time to form a strong water flow, take away impurities and foreign matter with small specific gravity in time, and discharge it from the overflow washing tank to complete the cleaning effect and separate the soil and sand.

How to reuse the soil after sand washing?

1. It is used to burn bricks; 2. Return to the field to plant crops; 3. Return to the park to plant grass and flowers; 4. Used for roadbed filler.

The cleaned sand and gravel can be used as configuration concrete, which is used in the middle area of the building, which meets the construction sand standard and has a large market demand.

In the form of **.

1. Sandy soil refers to the soil with a large sand content, rough particles, fast water seepage, poor water retention performance and good aeration performance. 2. Loam, refers to the soil particle group, which is coarsely combined into soil with moderate content of clay particles, silt particles and sand particles, and the particle size is between to. The texture is between clay and sand, and has the advantages of clay and sand, with good aeration and water permeability, water retention and temperature preservation performance, drought and waterlogging resistance, strong stress resistance, wide adaptability, long cultivation period, and easy to cultivate into high-yield and stable-yield soil.

3. Clayey soil is a kind of soil, which has the characteristics of good water retention performance. Low sand content, fine particles, slow water seepage rate, good water retention performance, poor aeration performance - soil.

Characteristics of sandy soil: the sand content of Wang sandy soil before elimination is more than 50%, and the clay content is less than 30%. Therefore, the pores between soil particles are large, the capillary action is weak, and the water retention is poor.

However, the sandy soil has good permeability and is not drought tolerant, and the soil microorganisms are predominant. The organic matter of sandy soil decomposes quickly, accumulates less, and nutrients are easy to be lost, resulting in a relatively poor variety of nutrients.

Characteristics of clay: its texture is heavy and clayey, and there is a lack of large pores between soil particles, so it has poor aeration and water permeability, and is neither drought nor waterlogging. However, it has strong water retention and fertility retention, fertilizer tolerance, nutrient is not easy to leach, nutrient content is richer than that of sandy soil, organic matter decomposition is slow, and humus is easy to accumulate.

This kind of soil has more water and less gas, little change in soil temperature, cold soil, and slow nutrient decomposition and transformation.

Characteristics of loam: The nature of loam is between sandy soil and clay soil, and its tillage and fertility are better. The soil of this texture is aerative and permeable, drought and waterlogging tolerant, and has strong stress resistance.
