АRК-003 Automated cutting complex

Complex for cutting foam concrete in the manufacture of foam conctere products.

Developed by our company ARK-003 Automated cutting set is multi-functional because it can saw different porous and light types of concrete (foam concrete, gas concrete, and polystyrene concrete). Result of sawing, i.e. blocks dimensions and surface quality meet severe requirements of standards (1st category acc. to GOST 21520-89).  Band saws saw mass in vertical and horizontal planes. During sawing in vertical or horizontal planes you do not have to move or position mass. In the process of sawing cycle a mass is located on the mold basement which is rigidly fixed on railway track with a special clamp. As far as you do not have to move or position mass, its integrity is not effected a lot. Also you can saw a mass at any stage of strength development. The cutting set is controlled by one operator from the control panel. Time needed to saw a mass of volume 0,85 m3 depends on required blocks sizes and is in the range of 6-9 min. The machine capacity per one 8hrs shift is up to 60 m3. Life time of band saws if sawing gas concrete, foamed concrete or polystyrene concrete is 600-1500 m3  (according to our company statistics) and depends on used aggregates and material density. Considering price for band saws from the leading manufacturers (USA, Germany) sawing of gas concrete, foam concrete or polystyrene concrete will cost from 10 to 20 rubles for 1 m3.

The cutting set is easy to embed in any existing lines of other manufacturers. There are technical solutions which allow sawing mass of sizes 2400х600х300 mm obtained on the other manufacturers’ molds. Using the ARK-003 Automated cutting set you get high quality blocks and also do not depend on time of mass setting strength because you can saw it at any stage of strength development. Sawing technology using band saws provides production of blocks of any sizes within the accuracy + 1 mm and surface quality which answers standards. ARK-003 cutting set allows reducing quantity of defects (thanks to sawing accuracy), eliminating numerous manual operations, increasing labor efficiency and cut personnel (1 operator maintains the set).

COMPARE BLOCKS QUALITY

Concerning different options of equipment for sawing porous concrete with bars, chains and circular saws it is necessary to take into account: - mass can be cut with bars only if material has definite yield and low density. If mass was “overdeveloped” you will not be able to saw it with a bar. If during sawing process bar interferes with some firming (large sand grains or cement fisheyes) it side-tracks. Also when sawing a yielding mass with a bar cut-off pieces are not taken away from cuts but remain on block walls and as a result, quality lowers. Blocks often stick together in sawn mass or after they are laid on pallets. If using bars a mass is not completely cut at the bottom.
