Autoclave Aerated Concrete Block Production Line Designing Scheme
1. Product Principle
Technology location point
Production and application of aerated concrete has more than 40 years history 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 under 3mm, take wall heating transmitting coefficient as 1, when concrete slot become over 3mm, take wall heating transmitting coefficient as 1.5). Based on the history of the aerated concrete development, only high quality products can bring a prosperous market. Thus, this scheme designed according to China standard GB11968-2006.
The product is aerated concrete block. Capacity is 150, 000 m3/year. The first period can be collocated according to 100, 000m3/year. Considerate the customer requirments, make reservation for panel materials.
According to GB11968-2006 standard 04～07 grade.

2. Technical Summary
1) Raw materials storage and process
Flyash powder and plaster
Flyash powder(considerate of both for dry and moist materials.), phosphate plaster and waste slurry are mixed according to a fixed proportion, and store the mixed slurry to 50m3 storeage container. To pump the mixed slurry by lurry pump to slurry mixing tank.
Numbly lime is carried to the factory by a dump truck and unloaded to the lime material shed. Then it is sent to compound pendulum jaw crusher to shatter after manual estimate, and is sent to lime head container by bucket elevator after it is shattered. The lime is sent to the high pressure mill by bin bottom feeding machine to pulverize. The pulverized lime sent to bucket elevator by mill exit helix conveyors, and then it is sent by bucket elevator to the lime powder container in the dosing building for further use.
The cement is carried into the factory by bulk-cement delivery tanker and pumped directly to the lime powder container in the dosing building for further use.
The sacked aluminium paste is bought from other places in the country and stored in the aluminium paste warehouse. Use electric block suspend it to the 2ed floor of the dosing building, and put it in the aluminium paste blender after estimate is done. Then it will be stirred into suspension for use.
Additives are brought by the specified manufacturer and stored in sacks according to the material quantity.
Scrap material, waste slurry
Scrap material cut by the cutting plane line, falls into the bottom chute, flushed by water into the waste slurry pool in the bottom of the cutting machine, and is pumped to the waste slurry storage tank by vertical mud pump. When it reaches a certain concentration, pulp it together with fly ash and adjust the proportion. Finally, put it in the slurry storage tank for use.
Magnesite (while producing sheet material)
Magnesite is sacked powder material and is delivered by bucket elevator or strength to powder container for use. This storehouse is used to store powder lime while not producing sheet material.
2. Dosing, stirring, pouring
When the valve of bottom of the slurry storage tank is opened, slurry is put into slurry metering balance of the dosing building to measure. When the weight of slurry reaches the dosing requirements, the dumping valve is shut by automatic system and dumping is stopped. The measured slurry is put into the pouring blender directly.
Cement and lime are delivered into electronic powder metering balance by single-solenoid machine in the bottom of the storehouse, and then are sent to pouring blender by helix transport machine after cumulative metering.
Aluminium powder is put into aluminium powder blender after it is measured by specific metering device. It is made into suspension and this is done once per mould.
The feeding order is: ①flyash and gypsum, ②additive, ③cement, ④lime, ⑤aluminium powder suspension.
Before pouring, the temperature of slurry should reach that of the technological requirements. While pouring, mould is delivered right under the pouring blender by shuttle, and the unloder arm at the bottom of the pouring blender drops, pours and hoists gradually through cylinder as the level of material goes up. After pouring, mould is moved in maintenance room to stay still and maintain first.
