Classification of Frac Sand

The frac sand can be divided into different types according to different specifications, and following are some general classify standards.
1.Classify according to strength
High strength frac sand
According to new standard of GB/T 17431.1—1998, high strength frac sand is a kind of structure light coarse aggregate, whose strength grade is not less than 25MPa. Its technology requirements are as same as ultralight and ordinary frac sand except density degree, cylinder compressive strength, strength grade and water absorption which have special index. High strength frac sand always with low productivity, high cost, high additional value, and price is higher than ultralight and ordinary frac sand by 50%
Ordinary frac sand
According to new standard of GB/T 17431.1—1998, high strength frac sand is a kind of structure light coarse aggregate, whose strength grade is not less than 25MPa. Ordinary frac sand can be used widely and with high market potential
2.Classify according to density
According to density, frac sand can be divided into general density frac sand, ultralight density frac sand, and extra light density sand
General density frac sand
General density frac sand refers to frac sand that density is more than 500kg/m3, whose strength is higher relatively, and often used in structure thermal insulation concrete or high strength concrete.
Ultralight density frac sand
Ultralight density frac sand refers to frac sand that density is 300～500kg/m3, which usually used in heat insulation concrete and heat insulation concrete products
Extra light frac sand
Extra light frac sand refers to frac sand that density is less than 300kg/m3, whose heat insulation performance is very high but with very low strength. It is usually used to produce extra light heat insulation concrete or heat insulation concrete products

3.Classify according to shape
According to shape, frac sand can be divided into macadam frac sand, spherosome frac sand, and cylindrical frac sand

Macadam frac sand
Macadam frac sand generally used in natural ore producing, and it is made from rock smashing,  roasting to flour sifting. It also can be made by directly crushing and sifting from nature or man made light material such as pumice, scoria, coal cinder, nature or calcined coal gangue.
Spherosome frac sand
Spherosome frac sand is made by disk pelletizer. It is made by the process from raw material crocus and then prilling mixed with water. After made into balls, which need to roasting or maintenance before turn to frac sand. In general, Chinese frac sand is such a product.
Cylindrical frac sand
Cylindrical frac sand usually made by shaping. It is craved into article mud, and then craved into cylindrical. Such a product is applied in high plasticity clay material, however, output is lower relatively. Cylindrical raw material is roasted by rotary kiln and the cylindrical rolling to oval in the kiln

What is Frac sand rotary kiln

Frac sand rotary kiln working principle
 Frac sand rotary kiln in rotary kiln production temperature (950 ℃ ~ 1050 ℃), which burning super fine kaolin technology, mature, domestic advanced, represents a super fine kaolin burning technology development direction. This burning technology with low energy consumption and high output, when the product after dehydration, decarburization whitening, stable performance, which can be used for paper, coatings, and other industrial areas.
 Frac sand rotary kiln product features
Frac sand rotary kiln is widely used in dolomite and kaolinite, bauxite, refractory burden, cement, limestone, titanium iron powder, mining, activated carbon, coke, kuangfen, alumina, magnesium oxide, zinc oxide, cement and other special industries.

Insulating fire bricks,Fire Brick,Refractory Brick,Insulaation Firebrick

Insulating fire bricks are soft and light in weight. They can be easily cut by handheld hack saw or any other hand tool like chisel or even drill bit. Color of insulating fire bricks varies but usually they come in shades from light brown to white, see pictures. In refractory air is the best insulation and this is why insulating firebricks have excellent insulating properties. Their body is made of tiny air spaces similar to honeycomb effect. How to use light weight fire bricks insulation Use of light weight fire brick insulation is broad, mainly in industrial and hobby kilns heated up with either electric spiral elements or gas burners, furnaces, both for hot face lining or outer back-up heat insulation. Advantages Produced with unique advanced technology, the clay and high alumina heat insulating fire bricks possess the characteristics of high intensity for pressure and good thermal shock stability. The use of the bricks can reduce the heat capacity of kiln walls and promote the heat efficiency of kilns. The insulating fire brick is applicable for constructing industrial kilns and inner lining of kilns。 Do not confuse lightweight insulating fire bricks with heavy dense firebricks. Insulating bricks are refractory too and of course withstand very high temperatures range BUT for purpose they have very low thermal conductivity and don’t absorb the heat well at all. Light weight insulating fire brick. Those are intentions for heat insulation. For instance if you used them for building of the hot face in a wood fired oven (for cooking) the oven wouldn’t cook, because it wouldn’t store and hold almost any heat. You can however use these insulating fire bricks on the outer side (of the heavy firebrick walls, vault or under the floor bricks and slab) to prevent the soaked in heat in the chamber’s body mass from escaping and achieving superb results. Meaning well insulated oven which will hold the absorbed heat in its mass, where it should be to cook for long time.

The refractory material refining quality steel casted by Henan province has reached top level of China

Currently, tourisms learn from Technology Department of Henan that the project of refractory material refining quality steel undertook by Luoyang Refractory Research Institute has passed acceptance check.. By carrying such an project, they have solved the key technology problem of short life span of LF+VD refining ladle refractory material that used in casting steel, and the life span increases from 85 heats to 135 heats. The person in charge of Technology Department of Henan has said that such a refractory material project has obtained two patents, formed productive capacity of 15 thousand ton per year and increased output value is 133 million. The appearing temperature of refractory material used by refining quality steel is lower 60℃～80℃ than ordinary ladle, which obviously reduces the power consumption of per ton steel, and very important for saving graphite and reduce heat loss of ladle. Now, with industrial structural adjustment of steel industry and increase of high quality special steel, which project carrying by Technology Department of Henan will promote such a proceeding in a big degree. If the factory in China can turn 5 million ordinary steel making to refining steel making per year, which will bring 12.5 billion income for steel industry, and the social benefits is obviously.
