Feeder unit

Intended for preliminary batching of initial materials (crushed stone, sand) in accordance with a given recipe and for supplying them to the inclined conveyor belt. Feeder unit consists of blocks with established belt feeders and conveyors.

Raw materials are discharged into tanks equipped with vibratory feeder and sieve to catch oversized fractions. Vibrators located on the sieves and side walls of the tanks prevent materials from getting stuck. Conveyor belt is equipped with safety system. Tanks are made with capacity of 8 and 16 m3.

Switching to a different recipe of the asphalt mix can be made online without shutting down the plant. Application of frequency converters allows to change the performance of the belt feeders from the operator’s cab remotely. Herewith all parameters of the belt feeders are adjusted automatically.

Dryer unit


Intended for heating and drying of  stone materials to the state which provides the mixture preparation. The Dryer unit consists of dryer drum, heating unit, dust filtering system.

The use of frequency converter in the drying drum control allows to start it smoothly, change rotation speed and adjust optimal temperature. Thermal insulation inside the drum reduces heat dissipation and improves efficiency. Exterior of the drum may be lined with polished stainless steel. Construction of interior provides efficient heating of materials and minimum fuel consumption. Dryer can also be used with damp raw materials. Plant operates on natural gas or liquid fuel (black oil M100), full combustion is achieved by thorough heating of the oil inside the tank and fast heater, use of high-capacity smoke exhauster, modern burners and automatic temperature/rarefication level adjustment inside the combustion space. Switching between the fuel types can be done in short time.

Combined dust filtering system


Consists of:

* Pre-cleaning stage, including a direct-flow cyclone-dust collector; designed to capture the coarse dust

* The second stage of cleaning (block cyclones);

* The third stage of cleaning (wet gas cleaning).

The third stage consists of scrubber "Venturi", drip tray and water supply system.

Furnace unit


Furnace unit is intended for fuel burning to obtain high temperature gas environment in the drying drum. The burner control is performed by output parameters – the temperature of stone materials and waste gases. Temperature control in the drying drum is carried out remotely from the control cab by changing the heat productivity.

Mixer


Is used for sorting and batching of heated sand and macadam, batching of bitumen, mineral powder and dust, preparing asphalt-concrete mix and its dispatch into ready-mix unit or directly into trucks.

The unit is a tower consisting of blocks located in accordance with technological process of mixture preparation:

-         Screen block

-         Upper block including the bin of hot sorted stone materials and the bin with compartments for mineral powder and dust

-         Middle block with weigh batchers on the strain gauges (including sensor of  bitumen level) and mixer

-         Bin for surplus and oversized materials

The hot bin is equipped with sensors of high/low levels of stone materials, mineral powder and dust. There are sensors of temperature control in the compartment of stone materials and before the bitumen batcher. There is possibility to work passing the screen through the channel “by-pass”.

The are strain gauges of stone materials, mineral powder and dust in the construction. There is an infra-red sensor of temperature control at the place of asphalt discharge.

Pneumatic of CAMOZZI allowed to increase safety work of asphalt-mixing plant.

Mineral powder unit


The mineral powder unit is used for receiving, temporary storing and delivering the mineral powder to the receiving device of mixer mineral powder elevator. Bins are available in volumes of 23 m3, 32,5 m3, 45 m3, 60 m3. The equipment for mineral powder production has batcher on strain gauges, aeration system, level sensors system.

Dust unit


Collects dust caught by dust filters and feeds it via elevator to the mixer. If necessary, dust can be dispatched via loading auger into trucks.

Mineral powder and dust bins are equipped with high and low level sensors. Continuous sensors can be installed as well. Aeration system at the bottom of each bin prevents loose material from choking-up.

Ready mix unit


Is used for temporary storage and dispatch of prepared asphalt mix into motor transport. Asphalt temperature remains constant for a long time due to the thermal insulation of the hoppers. Side walls and gates are heated with electrical heaters. Skip hoist of the unit is designed to start and to stop smoothly.

Ready mix unit consists of collecting bins, holding bin for ill-conditioned materials dumping, platform, skip, winch, emergency stopping system of the skip.
