1. product introduction:

aerated concrete production line mainly uses fly ash (slag) as the production raw material, lime and cement as the cementing material, and aluminum powder as the aerating agent. The aerated concrete is produced by crushing, measuring, mixing, pouring, resting, cutting, steam curing and other processes. Aerated concrete is a new type of wall building material, which has the advantages of light weight, heat preservation, heat insulation, energy saving, waste, environmental protection construction, convenient and fast.

4. raw material handling equipment

1 Jaw Crusher
is mainly used for medium and coarse crushing operations of various materials with compressive strength not exceeding 320 MPa. It has the characteristics of large crushing ratio, high output, uniform product size, simple structure, reliable work, simple maintenance, and economical operating costs. The crusher has been widely used in mining, smelting, building materials, highway, railway, water conservancy and other departments.

jaw crusher: When working, the motor drives the eccentric shaft to rotate through the pulley, so that the movable jaw periodically approaches and leaves the fixed jaw, thereby squeezing, rubbing, grinding and other multiple crushing of the material, making the material from large to small, Gradually fall until it is discharged from the discharge port.

2 Ball Mill
It is suitable for grinding various ores and other materials, and is widely used in mineral processing, building materials and chemical industries. It can be divided into dry and wet grinding methods. According to the different ways of ore discharge, it can be divided into two types: lattice type and overflow type.

3 beater
injected into the pool and mixed to form a slurry.

4 Storage Bin
for the storage of prepared fly ash slurry or mortar, with slow mixing to avoid slurry settlement. Adopt planetary drive stirring method.

5. batching pouring equipment

1 Measurement

metering scale mainly measures each raw material, and after stirring, it is finally injected into the pouring mixer for pouring and stirring.

2 Pouring mixer

is a material mixing machine for steam curing aerated concrete body before pouring, which is located above the body mold. It is used to stir the slurry, cement, quicklime, gypsum and aluminum powder paste suspension injected into the tank according to a certain ratio to make it evenly mixed and fully react, and inject the mixture slurry into the mold frame in time.

3 Mold

the combination of the mold and the side plate can contain slurry, static curing foaming and curing into a green body. Mold specifications: 4.2m,4.8m,6m

4 Side Panel

the side plates to carry out cutting, rack and steam curing.

5 Primary Care Room

After pouring, the mold is pushed into the primary curing room with a conveyor chain for initial gas condensation. The room temperature is 50~70 degrees, and the initial curing time is 1.5~2 hours (according to favorable geographical conditions, this process can be avoided)

6. turnover cutting equipment

1Overturn sling

the turning sling, and is hung on the cutting table or cutting trolley, and demoulded for cutting. In addition, the demoulded mold frame and the returned side plate are combined and hoisted to the pouring return line for circular pouring.

2vacuum suction hood

After the blank is cut, the top layer of blank waste can be removed by the suction hood, which can improve the utilization rate of waste.

3Step-by-step cutting machine
: the overturning hanger turns the mold with the blank body 90 degrees in the air and places it on the cutting trolley. Demoulding leaves the blank body and side plates on the cutting trolley. The cutting trolley is driven by the motor to complete longitudinal cutting, groove milling and horizontal cutting through the slitting device. After the cutting trolley continues to walk to the central position of the crosscutting device to stop, the crosscutting device is started, and the crosscutting frame cuts vertically from top to bottom to complete; the cutting trolley travels to the marshalling sling, and the blank (with side plates) is hoisted to the steam curing trolley by the marshalling sling, and the cutting trolley returns to the original position for the next cutting cycle.

4Turnover Table

After the blank is cut, the turning table turns the blank 90 degrees to remove the bottom waste, thereby improving the utilization rate of waste products.

5semi-finished product sling

cutting is completed, the blank is hoisted to the steam curing trolley through the semi-finished lifting tool for grouping into the kettle.

6Steam-curing Trolley

steaming trolley is a carrier that carries the side plates together with the blank in and out of the autoclave. The cut blank is hoisted to the steaming vehicle together with the bottom plate. The trolley carries the bottom plate together with the blank body and is grouped into an autoclave for steam curing.

7. finished product out of the kettle equipment

1Finished fixture

hoisted to the packaging line for final packaging.

2snapping board machine

to separate the aerated sheet products that adhere to each other after curing during manufacture from each other for transportation and use.

3Autoclave

autoclave is a large pressure vessel for steam curing of pressurized bricks or standard bricks pressed by aerated concrete, lime sand, fly ash, etc., and the hydrothermal reaction of CaO-SiO-H O is completed in the autoclave. At the same time, it is also widely used in other production projects that require pressure steam curing production process. Such as high-strength gypsum, insulation materials, rubber products, high-strength glass, cement pipe piles and wood, medicine, chemical and other industries. The company can also be equipped with various forms of pressure kettle according to user requirements to meet the needs of users for a variety of purposes.
