Batching plants for ready mix or precast production ssentially differ only in the type of mixer. Standard batching plants for the ready mix production are settled with pan or twin-shaft mixers
The advantage is the fast production and consequently shorter delivery time of concrete.
Batching plant is used for the production of concrete mixtures according to specified recipes. According to these recipes, is weighed the individual components in the desired ratio, then conveyed to the mixer, where is the whole mixture thoroughly mixed. from the outlet falls out finished concrete mixtures directly into a transport car or trolley. Using the weighing system can be sold as individual components such as sand or gravel.
The base is trained personnel between the number of 2-8 people. Individual processes are controlled either manuály or automatically where the operator enters only the amount and type of concrete mixtures.
Aggregate storage bins are divided into three main groups, namely on:
Cement silos are delivered according to the performance of the machine with a capacity of 30-100 t. Used for storage and for supply of machines with cement or with fly ash. They are equipped with a device for dust elimination, with Measurement of levels to determine the amount of material in a silo and with aeration device for improving the flowability of the material. The material is transported to the weighing system by a screw conveyor.
Because that most of the control elements is driven with air, it is recommended a separate source of pressurized air (compressor).
According to the machine's performance it is necessary to choose adequate el. connection. The machine is equipped with a switchboard for high and low voltage circuits and is equipped with control system for managing the entire machine.
Automatic control system offers the following possibilities: managing the entire cycle of mixing just by entering amount of a recipe, entering formulas, evidence of used material ,making sales documents .
Recycles concrete residues and waste water from the batching plant. During the maintenance of batching plant and mixer truck is produced a mixture of waste water, aggregates and cement. This mixture can be through recycling facility re-used for further production . On present trends and legislation is almost a necessity to have a recycling facilities.
For the operation of the batching plant is necessary to have a loader. The big advantage is own transport (sometimes even necessary).
Cladding and insulation (to ensures the operation in winter period)
Camera system - monitoring machine operation (increased security), monitoring of outdoor space (security)
