5.2 Introduction of results experimental and theoretical studies
Industrial introduction developed dezagregirujushchego devices in a sort mnogozahodnyh tapes has been realised at Open Society enterprise «Shebekinsky cretaceous mill». The Shebekinsky cretaceous mill - the largest manufacturer and the supplier high-quality tonkodispersnogo a chalk in Russia and the CIS countries.
Overall performance check dezagregirujushchego devices at separirovanii a chalk was an introduction main objective.At the enterprise make following marks of the separated chalk: MMOR MMS 1, MMS 2 in accordance with GOST 12085-88 and mark М15 on THAT 5743-02005346453-2008. Drying swept occurs in drum drier БН-2.0, levigating of a lumpy chalk is made in dezintegratorah, then the levigated chalk goes on separation to dynamic separator CSA 6, manufacturer MICRON PROCES (Spain).
Technical characteristics of separator CSA 6 in which it has been established dezagregirujushchee the device it is resulted in table 5.1.
Table 5.1
Technical characteristics of dynamic separator CSA-6
№ | Parametre | Value |
1 | The sizes, mm | 2300X6500 |
2 | The expense of air Нм3/ч | 30000 |
3 | Capacity of a drive, kw | 15 |
4 | Rotating speed of a rotor, mines-1 | 200 |
5 | Mass, kg | 8500 |
6 | Productivity, t/ch | 7 |
The chalk chemical compound is resulted in table 5.2.
Table 5.2
The chemical characteristic swept
Component | SiO2 | Al2O3 | Fe2O3 | CaO | MgO | SO3 | CO2 | CaCO3 |
The maintenance, % | 0,39 | 0,32 | 0,08 | 55,6 | 0,32 | 0,05 | 43,44 | 99,25 |
According to results of engineering calculations for separator CSA 6 have been made and fixed in separatsionnoj to the tape chamber mnogozahodnogo dezagregirujushchego devices with following parametres:
- Step of the screw of tapes of 4,6 m;
- Width of tapes of 0,08 m;
- Quantity of calling 8;
- Thickness of a tape of 5 mm;
- Angle of slope to a wall 15;
- Material of tapes Hardox 450;
- Installation height - 0,1 m above the bottom point of a rotor;
- The calling beginning coincides with the termination of the previous tape of the device.
As a result of industrial trials it is established, that there was an improvement of following indicators: a sieve residue, productivity, efficiency of process dezagregatsii (Table 5.3).
Table 5.3
Results of industrial trials of a dynamic separator with
dezagregirujushchim the device
Productivity, t/ch | Sieve residue R0045, % | Efficiency of process dezagregatsii, % | |
Before introduction | 7 | 0,5 | 14 |
After introduction | 7,36 | 0,3 | 29,4 |
It is necessary to notice, that productivity increase on 5,14 % and decrease in sieve residue R0045до of 0,3 % is connected with increase of efficiency of process dezagregatsii on 15,4 %. Insignificant decrease in cumulative specific power expenses for 0,5 % is marked also.
As a result of the executed works on device introduction in a sort mnogozahodnyh tapes in dynamic separator CSA 6 used for separation swept the device in a sort mnogozahodnyh the tapes, raising efficiency of process dezagregatsii it was recommended to use at separation inclined to aggregation tonkodispersnyh powders in a cement making, to exhaust and plaster.
Industrial introduction dezagregirujushchego devices and use of results of work in educational process are confirmed by certificates (the Appendix 8).
