Laxmi En-fab Private Limited

Overview
Project Proposal of AAC Production Line AAC Plant
Annual output 50,000-300,000m3 Production Technique

Product Principle
1) Technology Orientation:-
Production and application of aerated concrete has a history more than 40 years in China. Viewing from technology point, high quality products can use 3mm special sand slurry technology to meet the construction requests and 50% energy saving goals. (When mortar joint is less than 3mm, take thermal conductivity coefficient of wall as 1; when mortar joint is more than 3mm, take thermal conductivity coefficient of wall as 1.5). Based on the history of the aerated concrete development, only high quality products can bring a prosperous market. Thus, the technology orientation of this scheme is high-class products according to China Standard GB11968-2006.
2) Production Capacity:-
The product is aerated concrete block and the output is 150,000m3 per year. The first phase can be equipped according to 100,000m3 per year. There is a reservation of plate in consideration of user''s need.
3) Product Specification:-
Products conform to requirement of 04~07 grade blocks stated in GB11968-2006.
General Specifications of Aerated Concrete Blocks Process Flow

Main Equipment:-

1. Cutting Machine
2. Jaw Crusher
3. Ball Mill
4. Side Panel
5. Autoclave
6. Mould

Other Equipment :- Disk feeder, Belt scale, Belt conveyor, Pulping machine for sand after mill, Slurry pump, Slurry tank, Dust collector, Funnel style elevator for lime, Belt balance, Spiral conveyor etc.

Technical Parameter :- The formulation of aerated concrete of 600kg/m3 absolute dry volume weight is:

• Sand : Quick Lime : Cement : Gypsum = 68 : 20 : 10 : 2
• Aluminum accounts for 0.074% of the total volume of dry materials;

• Ratio of water to material: 0.6~0.65.

Application Range:-

• Autoclaved Aerated Concrete AAC Production Line
• AAC Plant used for products of AAC.

Operation Instruction:-
One-shift production may be put into practice when piecework system is carried out in the enterprise, but working hours must be prolonged and workers of the shift must be increased, and also labor protection should be done well. If four autoclaves are arranged in Phase One, fixed persons are organized in one shift.

Plant and system 

1. RAW MATERIAL PREPARATION

A ball mill wet-grinds the quartz sand with water to a sand slurry. The sand slurry is stored in slurry tanks and pumped into the slurry weighing hopper in the mixer tower. The binders are stored in silos. The aluminum powder or paste is prepared in a separate building where it is dispersed in water.

All the components are accurately weighed and are released into the mixer in a pre-defined order. The LAXMI recipe and temperature control system constantly monitors this process.

LAXMI also has the knowledge and the experience to produce AAC with alternative raw materials, for example with fly ash

 

2. CASTING, RISING/PRE-CURING AND MOULD CIRCULATION

The mould consists of four fixed sides and one detachable platform. The inner mould surfaces are covered with demoulding release oil before casting. This oil is applied either manually. The mix is then poured into the mould. A transfer platform transports the filled casting mould to the closed and heated pre-hardening area, also called the Pre-curing room. Due to the alkaline reaction of the aluminium in the slurry, many small bubbles develop in the compound. At the same time, the cake begins to harden. After a waiting time of approx. 2 - 3 hours, the preset "green strength" (cutting strength) is reached. The waiting time depends on the temperature in the Pre-curing room, but also on the quality of the raw materials used and the chosen recipe.

3. TILTING

The tilting crane tilts the mould by 90 Degree. The Tilting crane unlocks the mould and removes the mould body, so that the cake remains on Side plate for cutting. This tilting system has proven to be the safest method for tilting the cake into the vertical cutting position, as the cake is remaining on Side plate for the cutting process.

 

4. CUTTING

The cake in cut by high precision cutting machines. Cutting is done by pneumatically tensioned cutting wires. As the aerated concrete block stands upright, it is possible to use short cutting wires. The horizontal cutter and vertical cutter cut the block length and width. All waste material generated in the cutting process is collected in a basin underneath the cutting line, recycled, and returned to the production process.

 

5. AUTOCLAVING

After cutting, the green cakes are grouped on steam car by crane. The aerated concrete is hardened under steam pressure in special, sealed pressure vessels, the autoclaves, thereby achieving its final strength. The steam pressure is approx. 12 bar, the temperature approx. 192 Degree C. Usually, the hardening time is between 10 and 12 hours. The used steam for the hardening process in the autoclaves is generated in a steam boiler plant. Usually, high-capacity steam boilers that are operated by coal or wood are used to generate the steam.

1. RAW MATERIAL PREPARATION

A ball mill wet-grinds the quartz sand with water to a sand slurry. The sand slurry is stored in slurry tanks and pumped into the slurry weighing hopper in the mixer tower. The binders are stored in silos. It is also possible to mill the anhydrite together with the sand in the ball mill. The aluminum powder or paste is prepared in a separate building where it is dispersed in water.

All the components are accurately weighed and are released into the mixer in a pre-defined order. The LAXMI recipe and temperature control system constantly monitors this process.
