Making money out of thin air in a decent society has always been considered bad manners. We propose to make money out of sand and, moreover, a lot of it.
Very often, money lies right under your feet, sometimes you just need a certain amount of desire, work, knowledge and initial capital to just pick it up and put it in your pocket, having thoroughly cut off the roadside dust. In our case, the money is in the sand. Yes, yes, in the banal sand, which in its original form costs mere pennies, but it is worth putting a little work and the laws of physics on it, as it miraculously turns into a highly liquid commodity.
What is graded sand and what are its properties
Sand is perhaps one of the most common non-metallic minerals on earth. Due to its physical and chemical properties in its original form, it is an indispensable component of modern construction.
In its mass, it contains small grains of a naturally destroyed natural mineral, usually quartzite. And all these grains have a different size.
Fractionation is the separation of the sand mass by dry sieving on vibrating sieves with strictly calibrated holes of a given diameter and obtaining a material at the output that contains particles of a strictly defined size.
Enrichment is the separation of the main mass of sand from accompanying impurities, mainly clay.
The separation of clay makes it possible to achieve a qualitative improvement in the characteristics of sand, namely, its flowability increases and the quality and strength grade of concrete prepared on the basis of sand increases.
Areas of application for graded sand
The owners of sand pits, especially during the construction season and as a result of increased demand, very often neglect the quality of overburden. An array of sand lies at a certain depth from the day surface; as a rule, they are located above it. fertile layer soils, loams, clay, sandy loam, hard sandstones and directly sand. The more carefully the accompanying rocks are removed from the face of the quarry, the higher the quality of the sand. But the concepts of “how to do” and “how to do” are not always related concepts.
High-clay sand is the scourge of high-quality concrete. Modern frame-monolithic construction requires very high grades of concrete, which cannot be obtained on sands with clay impurities.
As for fractionated sands. The areas of its application are very wide.
Sand of fine fractions 0.1-0.3mm goes as consumable when carrying out sandblasting, quartz filter filler
Medium fractions 0.35-0.7mm as a basis for creating light, highly aerated soil mixtures with intensive type cultivation of strawberries and a number of berry crops, as a filler in the production of decorative castings and artificial stone
Coarse fraction with a grain size of 0.75-1.5 mm and above is an indispensable attribute when organizing construction works backyard landscapes, decorative finishes facades of buildings, the production of textured interior plasters, as the basis of soils for aquariums and terrariums.
Fractions of quartzites different size the grains are used to produce inexpensive abrasives.
How enriched sand is obtained
Enrichment, as a rule, consists in active and passive washing of the sand mass with water.
Active flushing is performed by blowing the conveyor line with sand with high pressure nozzles. In home and artisanal conditions of small production, a high-pressure washer of a professional or semi-professional class does an excellent job with this function.
Passive washing is the placement of an ordinary sandy mass in a container with water in a ratio of 1 to 3 and resting there for 3-5 hours until the clay particles soften and leave, followed by extraction. Significantly speeds up the process of using semi-active enrichment by washing quarry sand in an activator-type drum; in conditions of small production, a concrete mixer is excellent in a sand-to-water ratio of 1 to 2. In this case, 15-20 minutes of the process is enough.
Fractionation is carried out by dry screening of the sand mass on vibrating screens with the removal of calibrated fractions to a storage tank or simply to the working site. Intensity, processing time, the number of simultaneously selected fractions, their threshold sizes can be flexibly changed by simple settings.
Modern dry screening units work not only with sand, but also with granite chips / screenings / dolomites, limestones and others, which significantly expands both the functional and commercial possibilities of production.
Is the sand worth the candle
The most fundamental question is what is the profitability of such production and possible dates project payback.
Ordinary sand in various regions of the country costs from 150 to 250 rubles per ton, excluding delivery to the production site.
The price of enriched sand increases from 35 to 40% when shipped in bulk and up to 150% when shipped in packaged containers.
The enrichment costs consist of the purchase of a concrete mixer with a volume of 0.25 cubic meters or more, water consumption at the rate of 2000 liters per ton of raw materials, taking into account the possibility of clarification and cyclic reuse, electricity 1.8-2.7 kW / h, wages, in the case of attracting employees, rent for the use of the production site and tax deductions according to OKVED 08.12
The price of fractionated sand can increase depending on the fraction and its quality, by 120-1800%, and when calibrating and packaging the material, rare fractions, especially for the needs of a decorative nature and more.
The price of a complex for sand fractionation by dry vibratory sieving can range from 200 thousand rubles in a mobile version of low productivity, but with a fairly wide functionality, up to 10 million rubles or more for stationary industrial installations with a full cycle.

Sand is a hard rock that has been eroded into small pieces by water and wind over millions of years. Basically, such pieces are small, no more than a few millimeters in size, quartz grains - the most common mineral on Earth, consisting of silicon dioxide molecules. Silicon dioxide is found not only in the form of quartz on a sandy beach. You can easily find it in the package of chips or crackers. It is used there as a leavening agent, which means that it prevents food particles from sticking together. But this “sand”, which you can eat with crackers, is much smaller than usual, and it does not harm the body.
Let's see what, besides quartz, sand can consist of.
clear crystals here they are grains of quartz, but besides them we see grains of other minerals. The fact is that the sands are actually very different, depending on their origin. Volcanic sands, for example, may contain bits of red minerals, and then the beach will be red. There are several beaches in the world where the green mineral chrysolite is found in the sand. Therefore, the beaches there are green. And in some countries there are black sands containing many heavy minerals such as hematite or magnetite.
But the most interesting thing is that in addition to minerals, sand, especially sea sand, often contains fossilized remains or shells of the simplest animals and plants that lived millions of years ago.
These shells are usually made of calcium carbonate - that is, chalk. This is the same chalk that is used in the classroom to write on the blackboard, or outside to draw on the pavement.
Today, children are no longer interested in playing in an ordinary sandbox, because kinetic sand has appeared (in Greek, kinetics is interpreted as movement). It is represented by fine sand with the addition of special synthetic ingredients, thanks to which it becomes plastic, retains its shape, does not stick to hands and, most importantly, does not dry out. Classes with plasticine sand bring great pleasure to kids and, in addition, develop fine motor skills. Learn how to make kinetic sand at home, we will share with you the easiest and most affordable recipes.
