AAC Block Production Line

Brief Introduction

Autoclaved Aerated Concrete(AAC)brick/block is a light weight, multi-cell new construction material; the features include lower density, heat insulation, high strength, exceptional seismic performance, great work ability, good resistance to high temperature, maximum sound insulation and excellent adaptability. AAC is made from silicon material(silica sand, or recycled fly ash) and calcium material (lime, cement),which is widely used in building industry.

We have designed the AAC block production line with unique processes as well as innovative mechanical and control systems. This line is very efficient in producing quality AAC block. Its integrated technologies have reached an international level.

 

Cutting Machine Features

AAC cutting machine is the key equipment in the production of aerated concrete with annual capacity of 50,000 m3 to 200,000 m3. Its absolutely necessary for promoting the production capacity and quality.  Cutting machine series produced by our factory, can accomplish six-side cutting in one step, without the second lifting. Through having gone on technical reforming, our AAC cutting machine has stable performance and high efficient working, and it boasts by our customers. 

 

Autoclave Equipment Features

Autoclave is a comprehensive reaction vessel. From the beginning of the feeding - the discharge can be a higher degree of automation to complete the pre-set reaction steps, the control of temperature, pressure, mechanical reaction process (mixing, blowing, etc.) is an important parameter of reactant / product concentration and strict regulation.The loading car transports AAC cakes into autoclave,then steaming and maintaining with high temperature and pressure,the end products aac block come out

Hydraulic Mould Crane Features

This hydraulic mould crane is the main corollary equipment in the aerated concrete production. It allows the bricks together with the mould to be placed on the concrete cutting machine for die sinking or demolding. The bricks will be cut by the concrete cutting machine. Meanwhile, the hydraulic mould crane will recombine and clean the concrete mould, bottom plate. Then, it will brush the stripping oil for re-pouring.

 

Other Main Equipments in AAC Production Line

Jaw Crusher	Lime, gypsum, and such kind of bulk material need to be crushed as the first step in AAC Plant.
Ball Grinding Mill	The AAC material must be fully grinded in order to make better reaction. Ball Mill is used widely
Mixer	It’s the slurry mixing machine, also is slurry casting machine which can mix materials

Working process of AAC Plant

All kinds of raw materials Reserve Wharf → Measuring and Batching → Add water to raw materials and stir the mixture → Mould ready → Casting →Pre-maintain →Out of Mould →Turnover and cutting →Grouping and sending into the autoclaves → Autoclaving in high temperature →Final products out of the autoclave →Test the final products →Packaging →Sale
