Design-assembled concrete mixing units
The group of companies "ELTIKON" offers design-assembled BSU with a capacity from 40 to 320 m3 / hour. The number of mixers from 1 to 4.
Automated control system for reconstructed BSU AS "Beton-IPC / SKB-2"
Preparation of concrete mix - a key stage of technological process of production of concrete and concrete goods on which their reliability and durability depends. Conditions of preparation of concrete mix on the existing equipment do not allow to provide sufficient quality of preparation and stability of properties of the received concrete. Lack of control of a state loading выгрузочного devices, the unsatisfactory condition of the dosing equipment, the provided dispensing accuracy, lack of any information on a condition of concrete mix leads not only to accidental providing necessary indicators, but also to emergencies. At a dosage and unloading of components of concrete mistakes of the operator, unauthorized operation of the equipment and formation of marriage are possible. The lack of assessment of properties of fillers (humidity) results in wide spacing of indicators especially on consistence.
For compensation of heterogeneity of properties there is a need of increase in a consumption of cement for providing strength indicators of the prepared concrete mix.
Except all technical issues of ensuring technological process there is a problem of working conditions. On a status of dust content of the environment, noise level, vibrations of a working condition do not meet sanitary standards for production rooms.
Reconstruction of concrete-mixing workshop with elimination of above-mentioned shortcomings (replacement of the dosing equipment, the device of a system of preparation of giving and dosing of additives, control automation with preparation of concrete mix, etc.) will allow to provide stabilization of properties of concrete mix at its preparation without considerable capital expenditure and in short terms.
KTS basis the EXPERT of "Beton-IPC/SKB-2" - the industrial computer Mikro of RS, is located in the control cabinet the separate block and combined with modules of input-output of discrete and analog signals (USO). In total all modules of electronics make the technological station of computer control and management.
