Stationary concrete plants it is completed with bunkers dose, a pneumatic and the compressor, can work both in manual, and in automatic modes.
Installation of concrete factory is equipped with two concrete plants compulsory action in volume 1m3-3,5m3, productivity 35m3-320m3 at an o'clock everyone, and capacities for storage from 35 to 150 tons of cement and inert materials from 12 to 140 tons. All it is specified in the uniform elektronno-mechanical scheme shown in a control system by the operator.
The cabin of the operator is equipped with the monitor, the computer, the printer, the keyboard, etc. a necessary electric equipment.
Technological decisions in designs of bunkers-stores for inert materials, silos for cement and loading devices (accessories for the bunker - screw), and also mixing units are various enough. The bunker of inert materials are divided into 4 bunkers. Each bunker is used for a separate kind of inert materials (rubble, sand.) . Loading of inert materials occurs to the help of loading technics. For manufacture of more dense concrete the additional bunker for sand which is established at will of the customer is used. For each configuration of a working platform and productivity of factory, experts of the company count and optimise capacity and the form of bunkers for cement and inert materials. Work of bunkers of inert materials occurs at the expense of pneumatic pistons and air valves. Thus cement silos carefully hidro isolation for storage of cement without loss of quality and minimisation of time and expenditures of labour for their service.
The bunker for inert materials, depending on requirements of the Customer are issued in the opened.
Giving of inert materials in concrete plants (mixer) depending on productivity is carried out by a conveyor tape (the tape conveyor).
Tape conveyors are used at factories of company Krismak of the big productivity. Thus the width of a tape, a configuration and a corner of an inclination of the conveyor pays off so that to exclude glissades or tape sagging, productivity of the conveyor corresponds with productivity tenzo scales, and it, in turn, reduces loading on the tape conveyor and its bearing parts (rollers, support) and provides optimum productivity of all complex a feeder-dozator as a whole. Movement of tape conveyors is put in action at the expense of work of motors-reducers, rollers, bearings, drums of a transport tape.
In general, all offered designs of loading devices provide stable work and productivity of factory, and their choice depends on requirements of the Customer and a configuration of a working platform.
It*s not necessary to forget, that stable quality of concrete also depends not only on correct dispensing of initial materials, and and from quality of mixing.
Dispensing is carried out by means of scales dose which are established on bunkers dose, located directly over the amalgamator.
All amalgamators are made from stable materials and rotating knots hydroIsolation.
The assortment of amalgamators of the company includes classical amalgamators of drum-type type with the optimised design and calculated time of mixing of inert materials for maintenance of high quality of concrete.
Paddles amalgamators are more effective, than classical drum-type amalgamators – at the expense of presence of horizontal shovels, they in regular intervals coordinations a concrete solution in a countercurrent. Thus at the expense of high intensity of mixing, time of their work in a cycle more low, than drum-type amalgamators. A modular design лопастного the amalgamator and easily removable shovels facilitate their replacement and repair in case of deterioration.
Control systems of concrete factories are designed so that to supervise all operations which are carried out by the equipment and it is easy to operate factory work. At the same time, electric devices (the relay, gauges), established directly in a working zone – on элеваторах, bunkers, amalgamators, doses.
