The engine and gearbox are directly coupled to the wheels through the mixer and roller chain sprockets. Processing gears are installed so that the engine power is equally distributed on the twin axes instead of one axle. The gate of the mixer is watertight and is mounted to slide and adjustable slack pneumatic cylinder actuator is oversized. Torre The legs and supports of the tower are folding, sturdy and welded steel, providing high stability and vibration eliminated. The tower is designed and dimensioned to allow passage of trucks and their cargo below the mixer (3,50 m). Platform height scales with access ladder and walkways. With walkways Platform height sieves. Platform with walkways to inspect the height hot silo. Platform with catwalks in the hot elevator. Staircase with security guards, from the first stage to the screens. The floors of the platforms are slip sheet. Temperature gauge Pyrometer temperature indicator aggregates the dryer outlet.

5 CIRCUIT BITUMEN The bitumen is stored in tanks, is metered through a pump system of continuous operation in a pouring basin with heavy end by cutting three-way valve for branching the return excess to the tank. Bitumen pump, from storage tanks to the cube of heavy heating oil driven by electric motor 20 hp Injection of bitumen On the mixer, including: Pump oil heating bitumen electric motor driven 25 hp. Spray bar and pneumatically operated valves. EQUIPMENT AUTOMATIC CONTROL AND REGULATION OF PLANT Electronic. Prepared four aggregates, bitumen and two filler. With one or more preset dispensing, and includes: View mingled Setting a number of automatic repeat batches Tote batches View download times Regulation and bounds checking error in weighing. COMMAND AND CONTROL EQUIPMENT AUTO BURNER Electronic and with the following features and elements: Pyrometers, display and recording daily temperature of aggregates. Automatic fire modulator for temperature Preset within the required tolerances. It provides great fuel economy and prevents overheating of the mixtures. Indicator pyrometer temperature exhaust gas fireplace, security mechanisms that cut combustion if a limit is exceeded (adjustable at will) considered as dangerous to bad thermal performance. AIR INSTALLATION For operating the plant. Includes controller connecting pipe pressure, filters, gauges, strainers, etc.. In addition to a compressor provided with continuous control, driven by a 100 hp engine 380 V. Maximum operating pressure 7 kg/cm 2 INTRAME 350 RM - 5 -

6 BOILER Model V.12 DM.300 Approved by the Ministry of Industry. With a heat capacity of 800 Mcal/h at a maximum temperature of 210 C Fast performance is due to the incorporation of a helical coil which greatly increases the heat exchange surface. Oil circulation is effected by means of a centrifugal pump 2" driven by an electric motor of 10 CV. ELECTRICAL SYSTEM The electrical installation, including wiring of the entire plant and its related elements together. The entire facility is supplied with three-phase 380 V 50 Hz Wardrobe, includes full switchboard Starters for all motors supplied with the plant.
