Thermal insulation AAC brick production line , Best Autoclaved Aerated Concrete block plant           

Brief introduction of Thermal insulation AAC brick production line , Best Autoclaved Aerated Concrete block plant  :

 1,Introduction of Thermal insulation AAC brick production line , Best Autoclaved Aerated Concrete block plant

     Aerated concrete brick (light brick ) is the light and porous building material. It has light weight, keeping temperature ,unburned and other advantages .It can be made into many kinds of bricks(for example:600×200×100,80×80×180,240×115×53,600×200×125),they could be used industry building and common building .The size of brick can be changed by the requirement. They are more and more popular in the world .In the future , they will replace the clay brick completely.

2, Aerated concrete common conception of Thermal insulation AAC brick production line , Best Autoclaved Aerated Concrete block plant

     Common concrete density is usually 1600-2400kg/m3,but Aerated concrete are 500kg/m3,600kg/m3,700kg/m3.It has not the big grain ,main use silicon material (for example :coal ash ,sand ,stone dust and others ),through making the material small for example sand ,they can be used directly if has enough degree of small (for example coal ash .Mixing calcium material lime cement water to a special slop ,then add the aluminum powder and the additive .Make the aluminum dust and the special slop have a chemical reflect .Then produce Hydrogen to make the concrete slop to expanding or swell ,foam .Next ,put them into the curing room to concreting, cutting, steaming curing .last ,they will become the light brick ,the porous rate is 70-80%.

 3,Advantages of Thermal insulation AAC brick production line , Best Autoclaved Aerated Concrete block plant

   (1)light weight

     Aerated 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 .Then you can see ,it can save the material and cost ,it also fighting shaking.

    (2)thermal insulation

     It has high porosity. The delivery heating coefficient is 0.9-0.22W/ (mk),the same as  1/4 or 1/5 of clay brick ,so it is the best materials now in the world. Also have many kinds of raw material , have the lowest waste

     Main Raw Material:cement,lime ,gypsum , coal ash (fly ash), sand and other silicon materials ,  The formula is adjustable according to the raw material locally.

AAC Block Production Line of Hongfa

   *We are one of the best AAC block production line manufactures in China. We have exported our production lines to many countries --India, Vietnam, Indonesia , Myanmar, Middle East and so on.

   *We can supply our customer for designing project, production, installation, commissioning, training and good after-sale service.

   *The capacity of AAC block production line which we can design is 50,000 ~300,000 cubic meter per year.

The main process of produce:

1, Agglomerate lime is firstly crushed by jaw crusher, and then the granule lime is milled by energy-saving mill.

2, Mixing the fine grinding sands and the waste slurry for the slurry can improves effectively the stability of the slurry.

3 , The slurry and powder are weighed by electronic measurement. The measurement and pouring of batching plant are controlled by central control room.

4, The pouring method adopts fixed point pouring.

5, It chooses the JQF4.2 step by step cutting machine (Made in China). The maximum cutting size is 4.2×1.2×0.6m ,and the capacity of the cutting machine is about 200,000 m3 per year and choose JQF6.0 for 300,000m3 per year ,the maximum cutting size is 6.0×1.4×0.6m , The cutting precision reaches the China advanced level among the same size.

6, The autoclave kettle adopts 2 upward acting doors to decrease the time of the brick in and out of the autoclave and saves construction areas.

7,Using the integrated process layout, it is conductive to building warm insulate and automatic control of the line. At the same time ,it reduces the cost of construction.

8,Using hydraulic transport system instead of travelling crane can improve the stability of the system and save the procedure of application for inspection.

9,The waste on the bottom is cleaned by the hanger with cleaner and then sent to the autoclave kettle for autoclaved maintenance to realize no hard waste for production.

10,Comprehensive utilization of the waste material, waste water, waste gas and rain water helps make full use of the source and reduce emissions.

11,In order to simplify processing and reduce the cost of production, manual work is needed to clean and oil the molds.

*The production line is composed of raw material silo ,belt conveyor, ball mill, slurry storage tank , beater ,mixing and pour machine , mold , grouping conveyance mechanism ,cutting machine ,turnover conveyor device and tilting hoist, steam generating system(boiler),autoclave , steam distribution system , production conveyor device and production hoist and so on.

Ball mill:

Mould

Cutting machine

     The tilting hanger turns the mould 90 degrees in the air, demould the blank and puts it on the cutting table together with the side plate .The blank on the cutting table is cut by the longitudinal cutting device through the motor and its own running .After completion and running at the pause position ,the blank is cut horizontally by the cross cutting device when it is driven by the motor to the center of the blank .The cross cutting holder drops and cuts vertically from up to down until it is reset upward.

Overturned demould spreader and grouping hoister

     Overturned demould spreader is installed in green body transport machine, the lift and overturn of spreader is controled by hydraulic station ,overturn spreader make the green body, mould ,side plate overturned rotated 90°,hoisting in cutting platform or cutting trolley, after demould ,green body can be cutted ,overturned demould spreader make the mould and side plate fold ,and make mould put into the rail.

Autoclave

AAC block green body will be steamed in autoclave kettle and get high strength.

Capacity: from 50000 cubic meter to 300,000 cubic meters per year.

(1)Cement, lime ,fly ash style aerated block raw material proportion

(2) Cement, lime ,Sand style aerated block raw material proportion

Reference: cement is 42.5 Portland or 42.5 common cement,Aluminum power paste calculate to use according to 600kg/m³  

Remark: the accurate batching rate is adjustable according to the raw material locally.
