Product introduction:


I. Product Profile:


Aerated concrete production line is mainly made of fly ash (slag) as raw material, lime and cement as cementing material, aluminum powder as blowing agent, through grinding, metering, mixing, pouring, static curing, cutting, steam curing and other processes to produce aerated concrete. Aerated concrete is a new type of wall building material. It has the advantages of light weight, heat preservation, heat insulation, energy saving, waste-benefit, environmental protection construction, convenience and rapidity. It is a key environmental protection project promoted by the state.


2. Production process decomposition:


III. Raw Material Treatment


1. Jaw crusher


Mainly used for crushing and crushing of materials with compressive strength not exceeding 320 MPa. It has the characteristics of large crushing ratio, high output, uniform product size, simple structure, reliable operation, simple maintenance and economical operation cost. The crusher has been widely used in mining, smelting, building materials, highways, railways, water conservancy and other departments.


The working principle of jaw crusher: When working, the motor drives the eccentric axis to rotate through the belt pulley, so that the moving jaw periodically approaches and leaves the fixed jaw, thus crushing, rubbing and grinding the material, making the material from large to small, gradually falling down, until discharging from the discharge port.


2. Ball mill


It is suitable for grinding various ores and other materials. It is widely used in mineral processing, building materials and chemical industry. It can be divided into dry and wet grinding methods. According to the different ways of ore discharging, it can be divided into lattice type and overflow type.


3. Beating Pool


The raw materials are injected into the tank and mixed to form slurry.


4. Storage Warehouse


Used for storing prepared fly ash slurry or mortar, with slow mixing to avoid slurry settling. For tanks with effective volume greater than 100m, planetary drive agitation is adopted.


IV. Ingredient Casting


1. Measurement scale


Metrology said that the main raw materials will be measured, after mixing, and finally pouring mixer for pouring mixing.


2. Casting mixer


It is a material mixing machine before pouring of autoclaved aerated concrete green body, which is located above the green body mould. It is used to mix the slurry, cement, quicklime, gypsum and aluminium powder suspension injected into the tank according to a certain proportion to make it mix evenly, react fully, and inject the mixture slurry into the mould frame in time.


3, mold


The combination of the die and the side plate can fill the slurry and solidify the foam into the green body by static curing. Die specification: 4.2m, 4.8m, 6M


4, side panels


Side slab bearing body is cut, framed and steamed.


5. Nursery Room


After pouring, the mould is pushed into the primary curing room with a conveyor chain for gas generation and initial condensation. The room temperature is 50-70 degrees and the initial curing time is 1.5-2 hours.


V. Reversal Cutting


1. Flipping hanger


The overturning hanger turns the body (with mould and side plate) 90 degrees in the air. The lifting device is placed on the cutting table or the cutting trolley, and the demoulding is carried out for cutting. In addition, the demoulded frame and the returned side plate are assembled and hoisted to the pouring return line for cyclic pouring.


2. Vacuum suction hood


After cutting the green body, the top green body waste can be removed through the suction hood, which can greatly improve the utilization rate of waste.


3. Stepwise Cutting Machine


Working Principle: The overturning hanger flips the die with the blank in the air and sets it on the cutting trolley at 90 degrees. The demoulding leaves the blank with the side plate on the cutting trolley. The cutting trolley is powered by the motor. Longitudinal cutting, milling groove and horizontal cutting are completed through the longitudinal cutting device. After the cutting trolley continues to move to the central position of the crosscutting device and stops, the crosscutting device starts and the crosscutting frame starts from top to bottom. Vertical downcutting completes transverse cutting; the cutting trolley moves to the marshalling hanger and lifts the billet (connecting side plate) to the steaming trolley by the marshalling hanger. The cutting trolley returns to its original position for the next cutting cycle.


4. Turn-over table


After the body is cut, the turning table turns the body 90 degrees to remove the bottom waste, so as to improve the utilization rate of waste.


5. Semi-finished hangers


After the cutting is completed, the green body is lifted to the steaming car by semi-finished lifting gear and arranged in the kettle.


6. Steaming Car


The autoclave is a vehicle that carries the side slab and the body into and out of the autoclave. The cut green body is hoisted to the steaming vehicle together with the bottom plate. The car carries the bottom plate together with the body, marshalling into the autoclave for steam maintenance.


6. Release of finished products


1. Finished fixture


The finished product of the steaming kettle is hung to the packaging line for final packaging.


2. Plate Breaker


In order to transport and use, the air-filled sheet products which adhere to each other after solidification in the manufacturing process are separated from each other.


3. Autoclave


Autoclave is a large pressure vessel for steam curing pressurized bricks or standard bricks, such as aerated concrete, lime sand, fly ash, etc. The hydrothermal reaction of CaO-SiO-H O is completed in the autoclave. It is also widely used in other production projects requiring pressure steam curing process. Such as high-strength gypsum, thermal insulation materials, rubber products, high-strength glass, cement pipe pile and wood, medicine, chemical industry. The company can also design and manufacture various forms of pressure kettles according to user requirements to meet the needs of users for various purposes.
