Sand CLC block making machine, light weight block machine
Basic Introduction:
Autoclaved Aerated Concrete (AAC) is a siliceous material (sand, fly ash and silicon tailings such as waste porcelain clay, stone processing waste materials, blast furnace slag, etc.) and calcareous materials (lime, cement) as the main raw material, mixing fat gas agent (aluminum powder), by ingredients, mixing, casting, pre-raising, cutting, autoclave, curing process made of light porous silicate products, because by the hair contains a lot of gas even after the small pores, hence the name of aerated concrete.
Advantage of AAC:
- Lightweight: Porosity achieve 70% to 85%, volume density is generally 500 ~ 900kg/m3, as 1/5 of general concrete the 1/4of clay, the 1/3 of hollow brick, and similar with wood can float in water. It can reduce building weight, reduction in the cost of integrated building.
- Fireproof: Most of the major raw materials is inorganic materials, so it has good fire resistance, and do not emit harmful gases when meet fire. Fire 650 degrees, as a refractory material, the thick up of 90mm walls can reach to 245 minutes fire resistance, 300mm thick up wall can reach to 520 minutes fire resistance.
- Sound insulation: Due to a unique porous structure, so it has a sound absorption capacity. The sound absorption capacity can reach of 10mm thick wall up to 41 db.
- Insulation: As the material inside has a large numbers of the pores and porous, which has a good thermal insulation properties. The Thermal conductivity is 0.11-0.16W/MK, as 1/4-1/5 of brick. Typically, the insulation effect of 20cm thick aerated concrete wall is equivalent to 49cm thick solid brick walls ordinary.
- Permeability: Result of material by the composition of many independent small pores, the moisture absorption is slow, in the volume of absorbent is 5 times of clay saturation do. When used in the bathroom, the wall can be treated to interface directly paste tiles.
- Anti-seismic: The same building structure, improve the two seismic than the brick level.
- Green: Manufacturing, transportation, all use the process of pollution, to protect arable land, saving energy, is one kind of a green building material.
- Durability: material strength is stability, in the specimens tested after one year of atmospheric exposure; the intensity increased by 25%, and remained stable after ten years.
- Shortcut: it has good machinability, can be sawed, planed, drilled, nailed, and available appropriate as bonding of adhesive material, so create favorable conditions for building construction.
- Economies: An integrated lower cost than using more than 5% of solid clay bricks, and can increase the usable area, greatly enhance the utilization of floor space.
Main Equipments in AAC Production Line:
- Material-milling Equipments:
a. Crusher: Lime, gypsum, and such kind of bulk material need to be crushed as the first step in AAC Plant.
b. Miller: The AAC material must be fully grinded in order to make better reaction. Ball Mill is used widely, it has two types: dry and wet, can be chosen upon requirement.
Material Metering Equipments: Computer Control Automatic Metering System is commonly used as measurement of raw materials.
Material mixing and casting equipments: Mixer, it’s the slurry mixing machine, also is slurry casting machine.
- Cutting Machine: the AAC blank is formed after casting and pre-curing, as the size is too large, it must be cut to achieve the required product size.
The entire center feeding: Sand Making Machine Material falls the feed hopper, then enters the high-speed rotary sling wheel from center feeding hole, which is speeded immediately in the sling wheel. Sand CLC block making machine, light weight block machine The speed can reach several dozens times of the gravity acceleration. Then Sand making machine is thrown from the sling wheel. First, Sand Making Machine is crushed with other rebounded material fell freely from the sling wheel.

Then both of them are impacted to the material lining (rock-rock) or strike back block (rock-iron), rebounded and stroke to the Good of eddy cavity of Sand making machine in the inclined-up direction. Then Sand CLC block making machine, light weight block machine moves along deflection-down, and forms a continuous material curtain with the material from the impellers passage. Just like this, the material is stroke, rubbed, crushed twice or more, then is discharged from the down discharging hole. There is little loss for medium-sized and fine sand and stone powder. Sand Making Machine The grade and the fineness of the sand for construction after being washed can be up to the national standards, such as sand for construction and cobble and broken stones for construction. There are no other wear parts except the screen mesh. Sand CLC block making machine, light weight block machine has longer service life and little maintenance chance.
