- The values ​​of specific indicators calculated on the main parameter (P) - the nominal performance for the conditions of preparation of fine-grained, sand or asphalt mixtures according to State Standard 9128-84 from source materials with volumetric mass 1.6 t / m ³ at initial moisture content of 5% and t = 140 ⁰C.

***

- If the duration of work in an atmosphere containing carbon monoxide, not more than 1 h, the maximum allowable concentration of nitric oxide, carbon can be increased to 50 mg / m ³ with a duration of no more than 30 minutes, up to 100 mg / m ³, with a duration of no more than 15 min-200 mg / m ³. Repetitive works under conditions of high carbon monoxide content in the working area can be produced with an interval of at least 2 hours.

****

- Data are presented for a unit operating with a nominal capacity of 48 t / h, with a moisture content of stone materials 5%, the temperature difference before and after heating - 140 ⁰ C, with standard materials and nominal fuel consumption.

*****

- The values ​​of emission of harmful substances from the stack into the atmosphere depends on the physicographic, climatic conditions, mode of operation of the unit, the type of stone materials and fuels.

******

- In the tumble dryer, except for the basic processes of fuel combustion and drying of stone materials, a decrease in the content of silicon dioxide (SiO2), part of the stone materials, due to the passage of a number of thermo-chemical transformations.

Preparation of the unit to work.

Prior to the start of operation of the unit operator shall ensure that all mechanisms and devices of the unit are in good condition, adjusted and lubricated, and minor faults reflected in the shift log prior to shift have been eliminated.

Control - measuring devices have a stamp and sealed.

Manometer arrows are in the zero position in the absence of pressure in the routes.

If there is pressure in the routes manometer arrows should show pressure:

• in the routes of fuel system - 1.5 - 5.5 kg/cm²;

• in the routes of the coolant - 5 - 8 kg/cm².

Lubricators of the unit heat system filled with the necessary quantity of oil and condensate in the pneumatic system and the coolant is removed.

Fuel tanks filled with with fuel.

Bitumen battery including the bituminous unit (consumable bitumen pot) filled with bitumen. The temperature of bitumen in the feed tank in the range 140 - 150⁰C, and the remaining tanks battery of bitumen 80 - 100⁰C.

Aggregate's mineral powder bunker is filled with powder.

Taps, cocks the components of the unit are in position, ensuring the execution of of working operations for the production of asphalt mixes. The system of steam heating of the unit is filed with steam (or other coolant), including the heating system in the mixer.

Heating of bitumen wire and partial heating of closing devices (bituminous cranes, valves) is enabled.

Mazut is heated in the fuel tank to a temperature of 95 - 105⁰S.

Bunker - storage of ready mix and the skip shall be exempt from the excess and oversize.

Pressure spool body spray system must be adjusted to the pressure of not more than 6 kg/cm².

Skip winch lift rope is in good condition.

Tube 3-way valve fuel tank should be in a position that ensures the circulation of diesel (heating oil) fuel tank for easy fuel filter - opened.

After 4 - 5 minutes after the ignition plug nozzle 3-way valve installed in the position of providing outflow of fuel oil into the tank for fuel oil, open the valve connecting the tank with black oil filter. You must then close the valve connecting the tank to the light fuel filter.
