The description of technological process

Preparation and warehousing of raw material
Cement and milled inert filling from cement carriers with compressor installation are loaded into silos. The silo of cement and the silo of filling are located in immediate proximity from ÄÑÊ (dosing unit amalgamator of components).
From silos cement and filling move to dosing units bunkers by means of horizontal or combined screw conveyors. Dosing of dry and liquid components is carried out by means of the industrial processor.
Water through the system of pipelines is filled in special tanks ÑÄÆÊ-3Ï before the shift beginning. In a tank for foam former aperture the concentrate of foam former, and in a tank for chemical agents necessary reagents are added. Liquid components (the concrete chemical agents) are mixed up, lead up to the set temperature and under the program are dosed out in the amalgamator. Thus the concentrate of foam former automatically mixes up with air in special foam generator up to the set frequency rate and as technological foam moves into the amalgamator. For maintenance of productivity and economy of the electric power it is recommended to fill in ÑÄÆÊ – 3Ï with warm water (not below 10-12° Ñ).

Mixing of components
Mixing of all dry and liquid components occurs in several stages. On the central control panel the factory makes the control, processing and management of all important functions of installation over all sites of preparation of aerated concrete mixes. The operator in the real time mode of traces all processes of operation of installation. In case of need the operator in a short period of time can correct or change the current structure, time of mixing, a temperature mode and other technological parameters on the electronic panel of the main board or by means of a computer. Also the operator can transfer the operation of installation in semi-automatic or manual control mode.

Formation, cutting, transportation
The ready mix through the bottom mouth of the amalgamator is unloaded into the metal form. The form of a file will consist of two parts – the pallet and a demountable curb. The pallet represents the carriage on four steel wheels with the wooden basis projecting above a metal skeleton. The demountable curb will consist of two parts the “ã” -shaped form and in assembled state forms four sides, forming the massif. Before filling with aerated concrete mixes, the demountable curb is assembled, lubricated with a special solution or laid by an oiled paper and put on the pallet. For maintenance of tightness, joints of the form are glued by a special sealant. In order to prevent damages during transportation, the sealant is delivered separately from forms and pasted by the Customer.
After filling with aerated concrete mix, the form by means of the positional conveyor, is delivered to a place of ensembling of stripping strength. Time of ensembling of stripping strength depends on many factors (concrete structure, brand of cement, temperature, etc.) and changes from 4 up to 8 hours.
For maintenance of highly strengthening characteristics of a material it is very important to provide a rigid temperature mode at the moment of strength ensembling. Depending on used materials it is necessary to maintain temperature of 40-50° C the section before massif cutting (4-8 hours) and 60-90° C the section after massif cutting (up to 16 hours). More exact temperature schedule is established by the Customer in an operating mode according to the results of control supervision. For providing of conditions of a mode heat and humidity processing, it is recommended to the Customer to organize hotbed designs or stationary tunnel chambers.
At the expiration of the strength ensembling period the demountable curb is disassembled, the pallet with the massif moves to a cutting section. The curb is cleaned, assembled, oiled, and installed on the free pallet and moves to filling under ÄÑÊ.
The massif, which has gained necessary plastic strength, is captured by the special positional conveyor and moves for cutting. At the first stage by means of screw milling cutter the top is sheared off the massif (up to 5 mm). At the second and third stage cross and longitudinal massif cutting occurs. After that the massif cut into blocks is rolled to a pushing conveyor for submission into chambers of heat and humidity processing. There is an experience of the tested variant of the arrangement of such chambers as “thermos” with use of exothermal effect of reaction of cement hydration.
If the Customer uses sand or large screening as fillers, there is a probability of pilling of material with subsidence of larger particles on the massif bottom that can result massif undercut. In this case in the wooden basis of the pallet technological flutes are slitted for passing of cutting strings up to the metal skeleton.

After the stage of heat and humidity processing, the cut massif is rolled out on the carriage on disassembly. Blocks are stacked on shipping pallets, pulled together with a fastening-tape and with the help of transporting mechanisms move to warehouse platform or to warehouse. The further curing period of finished blocks at positive temperature is determined by the Customer and makes from one to two weeks. The released pallet is cleaned, interlaid with layer or with oiled paper and brought into filling zone.

Chief mounting and putting into operation

The result of chief mounting and putting of the equipment into operation is considered to be “dry” trial start, commissioning and training of the Customer’s staff, manufacture of a trial lot of products with volumetric density of 600 kg / m3.
The density of 500êã/m3 is mastered after the certain term of operation, at the achievement of necessary professional skills of the staff and optimization of a mix structure by the Customer in his premises.
The same is for density of 400êã/m3 if quality of used materials allows.
Before putting of the equipment into operation the Customer should provide necessary raw material on the industrial platform.
By the moment of experts arrival for carrying out of chief mounting and putting of the equipment into operation it is very important that all the foundations are ready and fit the set sizes. The supply of a current and water should be carried out. It is necessary to have load-lifting mechanisms. All works on preparation of the premises and installation of auxiliaries should be finished. Works on preparation of a premise, assembling and installation of railway lines, filling of foundation and other building work are not related to installation. Those parts of the equipment which are provided by the Customer are not related to installation as well.
The staff which will operate the installation, should be on a platform during all term of installation and start-up of the equipment. The customer should provide electricians, mechanics and auxiliary staff for carrying out the installation works.
The customer additionally pays residence costs for specialists of Limited Company “ICC” in hotel, meals on the building site, transportation from hotel up to a place of installation and back, and also transport charges from Kaluga to a place of installation and back.
