1. Introduction Aerated concrete block is the light and porous building material. The concrete block product is characterized by the advantages of light weight, heat preservation, sound isolation, high strength, processable property and so on. It can be made into many kinds of bricks or boards according to different uses. They could be used in industry building and common building. They are more and more popular in the world. 2. Aerated concrete common conception Common concrete density is usually 1600-2400kg/m³, but Aerated concrete are 500kg/m³, 600kg/m³, 3600kg/m³, 3700kg/m. 3. Advantages of the product1). Light weight2). Heat preservation3). Sound isolation4). Save manpower5). Resist compression and fireproof6). Good processable property. 4. Main Features of the Machine: 1)The structure of the machine is simple and practical, it is easy to install and maintain. 2) After overturning, the blank stands vertically with the width of 60mm and the height of 1200mm, thus the cutting wire can be shorter and it is not easy to be broken and drifted, the cutting precision can be more exactly as well. 3) When the blank is moving along with the cutting cart, the vertical cutting is done by the vertical cutting device which is fixed. The horizontal cross cutting device is driven by the chain which can keep the cross cutting support running consistently when it is rising or falling, thus it can ensure the cutting precision. 4) As the blank stands vertically, the grooves on both sides of the blank (with width of 600mm ) can be milled at the same time when the blank is cut vertically, no groove processing device is needed. 5) The machine can produce both building blocks and slabs and the blank can be cut into six sides, therefore the quality of products can not be influenced by the mold oil and the deformation of the mold. 6) The machine is easy to operate. The cutting process of the machine (overturning, vertical cutting and cross cutting ) can be finished in different positions, therefore the operation is simplified and the maintenance is convenient.
