What is AAC Production Line ?
AAC block production line, also known as aerated concrete block line, is a kind of lightweight block production line. According to different types of raw materials, quality and processing characteristics of equipment, AAC block machines are differently designed. The production process are as follows: Mix fly ash or silica sand, slag and water into slurry, stir the slurry together with powdered lime, a certain amount of cement, plaster and foaming agent, and then pour them into the mold box. After resting foaming solidification, AAC lightweight block production line can cut them into blocks or plates in various specifications, and then send them into the autoclave by the steam-curing car. After high temperature and high pressure steam curing, AAC block machine can produce porous and light aerated concrete products. Adopting German advanced equipment, PLC automatic feeding and complete electric control system, our lightweight block production lines are quite famous both home and abroad. The whole aerated concrete block line includes feeding, mixing, pouring, preliminary maintenance, cutting, autoclaved maintenance, and so on.
Autoclave and boiler is the necessary equipment in AAC production line. Autoclave is mainly used to steam curing the AAC block and the boiler usually is a steam boiler and it mainly supply steam which makes the autoclave steam curing in a high pressure and high temperature circulation.
AAC Block Features
(1) light weight
Areated concrete density is usually 400-700kg/m3,(according the market in produce ), same as 1/3 of clay brick and 1/5 common concrete. So use the Light brick can reduce the weight of the build more, and also reduce the beam of roof and pillar press best and then, it can save the material and cost, it also fighting shaking.
(2) keeping temperature
It has many porous, the delivery hearting coefficient is 0.9-0.22W/(mk), the same as 1/4 or 1/5 of clay brick,so it is best materials now in the world. There are many kinds materials have lowest waste.
(3) High Strength
High pressure steam-curing autoclaving process gives AAC unmatchable strength to weight ratio, higher than even M150 concrete and far exceeds the building code requirements.
Being lightweight AAC drastically reduces the dead weight of building, resulting into reduction in steel (up to 27%) and cement (up to 20%) structural cost saving.Being 8 times the size of a clay brick, AAC wall construction involves 1/3 the joints, thus an overall mortar saving up to 66%.
