Concrete referred to as concrete, we are familiar with, widely used in various construction fields, is the use of cement as a cementitious material, sand, stone as aggregate, and water in a certain proportion, the formation of, however, concrete is generally used what sand? Which is good? What are the sand processing equipment for construction? Here to take you to understand one by one.

Concrete generally use mechanism sand

What sand is generally used for concrete?

Mechanized sand is generally used.

Sand on the market according to the source can be divided into natural sand and artificial sand, natural sand, including river sand, sea sand, yellow sand, etc., artificial sand, including mixed sand and mechanism sand, but with the various types of natural sand has been used as a building material for many years, the resources continue to decrease, while the infrastructure projects are increasing day by day, the increase in the amount of concrete, the demand for sand is also getting bigger and bigger, and the face of the river sand prices continue to rise in the face of the cost pressures brought about by limited resources and Under the dual factors of environmental protection, the use of mechanism sand is more long-term development.

Mechanism sand refers to the particle size of not more than 4.75mm particles, from a variety of ores (limestone, pebbles, granite, etc.) by professional mechanical crushing, sand making, screening and made of sand, only a few sets of equipment can be completed, access to low cost.

The fineness modulus can be artificially controlled by the production process, and the production can be organized according to the user's requirements.

It has better adhesion, more pressure resistance and longer service life.

Mechanism sand mineral composition and chemical composition and raw materials are consistent, not as complex as natural sand.

Mechanism sand application areas

What are the construction sand processing equipment?

Construction sand is less than 4.75mm particle size, fineness modulus MX 3.7-1.6 fine aggregate, in addition, the apparent density of sand, bulk density void rate, needle flake particle content, mud content, water absorption rate, etc. have requirements, so we must correctly select the equipment, there are many construction sand processing equipment on the market at present, the more commonly used are impact sand maker and composite sand maker, a combination of various aspects of the situation to choose.

1、Impact sand making machine

Processing capacity: 40-650t/h

Feed size: ≤50mm

Finished product size: 0.25-5mm

Set a variety of crushing modes in one, two feeding methods, in the mechanism of sand industry is more widely used in the new equipment, the finished product is relatively fine, through the four-port impeller design, crushing chamber impact angle to improve, through the amount of enhancement, large output, through the hydraulic adjustment system discharging, coupled with a large discharge port design, the material is discharged smoothly, which prevents the material from clogging, to avoid abnormal damage to the equipment, taking into account wear-resistant weekly guard plate and rock self-crushing point, reduce the cost of wear and tear.

2、Composite sand making machine

Handling capacity: 5-100t/h

Feeding granularity: ≤100mm

Finished granularity: 0-10mm

The main technical parameters of the optimization design developed into a new type of fine crushing/coarse grinding products, by the material moisture content is small, humidity is not greater than 15%, the spindle is equipped with a hammerhead, the material is continuously subjected to a series of high-speed rotation of the hammerhead impact and is crushed, the use of elasticity adjusting mechanism, into the non-crushable material can be automatically discharged, will not cause damage to the equipment, the life expectancy of the equipment has been increased by 2-3 times, coupled with the three-dimensional structural design, Small footprint, saving investment costs.

How much is the price of construction sand processing equipment?

The price has always been the problem that we are more concerned about, because the market has less than 100,000 yuan, there are more than 100,000 to a million dollars, do not know exactly how to choose, in fact, mainly because there are many manufacturers on the market now, processing technology and fetch, resulting in differences in quality, functionality, and then according to the model output, there will be a lot of difference, so it is necessary to consider more.

Regardless of which one to choose, as long as it suits you is good, the specific construction sand processing equipment price how much, welcome to call or consult at any time to ask the price to understand, there are managers to provide details of the single, are supplied at factory price, in addition, you are welcome to visit the plant to visit, see the scale, see the equipment, see the technology, or visit the nearby customer site, check the use of the situation, and immediately for you to arrange, and the late technical team door-to-door on the Equipment guidance installation, commissioning, operation training, regular return visits and a series of services.
