Sand is a very common material in our daily life, but the family of sand is also divided into coarse sand and fine sand.

The current situation, vigorously promote the construction of infrastructure, the demand for sand and gravel aggregate is also increasing day by day, the mechanism of sand has gradually become the main raw material of sand for construction, at the same time, in order to meet the requirements of different areas of use, generally divided into coarse sand, medium sand and fine sand, what is the difference between? What is the difference between coarse sand and fine sand with what sand making machine? Here for you to explain in detail.

What is the difference between coarse sand and fine sand?

Which is better for coarse sand and fine sand? Is the price the same? The degree of sand coarseness and fineness refers to the average degree of coarseness and fineness of sand particles of different grain sizes mixed together, and the difference between coarse sand and fine sand is mainly reflected in the fineness modulus, grain size, use area and price.

Coarse sand

Fineness modulus of 3.7-3.1, particle size greater than 0.5mm particle content of more than 50% of the full weight, the average particle size of 0.5mm or more gravel. Coarse sand is generally relatively inexpensive, instead of other sand with, cost savings, but the mud content to be a little heavier, more used in mortar flooring, as well as beams, slabs, columns, foundations and large volume concrete use.

Fine sand

Fineness modulus of 2.2-1.6, particle size greater than 0.25mm particles more than 85% of the full weight, the average particle size of 0.35mm-0.25mm gravel. The price of fine sand is slightly higher, the difference between medium sand and fine sand is not very big, general use in masonry mortar for masonry, and for sliding joints with the exception of the general construction of fine sand alone is rarely used. Except, the different sand in the hands, will find that the fine sand can be formed into a ball, the sand is very difficult to form a ball, loose easy to loose, coarse sand can not be formed into a ball at all, these characteristics also affect the application of the different sand in the various stages of the project.

What kind of sand making machine is used to make fine sand from coarse sand?

Coarse sand into fine sand machine also known as sand making machine, there are about a dozen kinds of the current market, with what machine is good? It is recommended to choose the impact sand making machine, the equipment combined with the actual situation of domestic sand and gravel production aspects of the development, recognized and favored by the user, because it is a collection of various crushing modes in one, dual-purpose distributing plate, deep cavity impeller design, throughput enhancement, high efficiency, 40-650 tons per hour, can handle ≤ 55mm coarse sand, equipment model complete.

Advantages:

Beat the coarse sand into fine sand, into round sand, cubic sand, also has the function of shaping, to meet the requirements of higher engineering.

The perimeter guard plate can be turned around up and down to prolong the service life, hydraulic cover opening device, convenient maintenance, shorten the downtime and improve the efficiency.

Combined throwing head, only need to replace the worn part, reduce the cost of use.

Self-circulation of airflow inside the vortex chamber, coupled with pulse dust collector and noise eliminator, realizes green sand making.

Selectable lubrication, bearing chamber thin oil type and grease type modular design, can realize the whole interchangeable.

How much is a coarse sand to fine sand machine?

Coarse sand making fine sand machine in the market use has been very common, there are many manufacturers have production, but due to the production technology, fetching materials and various aspects of the process is different, coupled with the output requirements, model selection, etc., resulting in fluctuations in the price of the sand making machine, the emergence of high and low situation, which manufacturer is good and affordable?

From equipment research and development, manufacturing, sales, after-sales and other aspects of the general mining machine manufacturers are independently completed, specializing in the production of various types of sand making equipment has more than forty years, has been to ensure that the material, workmanship, quality is more reliable, the middle does not go through other manufacturers and dealers, there is no question of price differentials, the specific coarse sand playing fine sand machine how much, welcome to consult online to understand, there are technical managers to send you detailed information for reference and comparison! The company provides a series of after-sales service, as well as a site visit to the factory, free transportation by car!
