RESEARCH IS CONSTRUCTIVE - TECHNOLOGICAL PARAMETERS OF INSTALLATION FOR PNEUMATIC MECHANOACTIVATION OF CEMENT
2013
The analysis of lowering of raw expenses on the modern production of dry construction compounds, steel concrete products and constructions is carried out. Considering the literary review, installation for pneumatic mechanical activation of cement of the continuous action is developed and created. The analytical expressions describing constructive technological parameters of a mixing and accelerating node of installation for pneumatic mechanical activation of cement are given in article. In pneumatic installation of the continuous action cement moves the dispenser. Process of mechanical activation in continuously operating installation depends on adjustable parameters of system to which the number of accelerating tubes belongs, diameter snuffl ed, diameter of accelerating tubes and the geometrical sizes of the working camera of installation. It is set that it is most expedient to apply pneumatic installations directly on productions of concrete goods, ZhBK and CCC as the maximum effect from cement mechanical activation is watched. Researches show that mechanical activation of cement allows to cut the cement expenditure to 17 %, and, therefore, to reduce prime cost of concrete goods, ZhBK and CCC, without changing qualitative characteristics of a ready-made product.
