Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard replaces GB/T 10171-2005, Concrete mixing plant (tower). Compared with GB/T 10171-2005, the main technical changes are as follows:

- the scope of application of the standard has been changed (see Clause 1; Clause 1 of the 2005 edition);

- a definition of rated capacity has been added (see 3.1);

- the term and definition of the dismountable mixing plant have been deleted (see 3.10 of the 2005 edition);

- a definition of discharge height has been added (see 3.11);

- the series of main parameters has been changed to correspond with the series of main parameters of the mixer (see 4.1; 4.3 of the 2005 edition);

- "Dismountable - not marked" has been deleted (see Table 2);

- the requirements relating to equipment noise are given separately (see 5.1.9 and Table 4);

- the content on dragline scraper feeding devices for star-shaped aggregate bins has been deleted, and content on hopper loading mechanisms has been added (see 5.3.1; 5.3.1 and Table 5 of the 2005 edition);

- the material weighing accuracy has been changed, and requirements for the dynamic weighing accuracy per batch and the cumulative dynamic weighing accuracy have been added (see 5.5.2.3, Table 7 and Table 8; 5.5.2.3 and Table 7 of the 2005 edition);

- "three-phase five-wire system" has been added (see 5.9.1.2; 5.9.1.2 of the 2005 edition);

- "the power supply and distribution should follow the principle of balanced three-phase supply" has been added (see 5.9.1.3; 5.9.1.3 of the 2005 edition);

- the statement "the main control room of the mixing plant (tower) has monitoring equipment or a good view of concrete discharge and of vehicles entering and leaving" has been deleted (see 5.9.2.4 of the 2005 edition); this content has been moved to the new 5.9.5;

- requirements for the functions of the control system have been added, such as "the computer control system shall have fully automatic and manual production functions; manual production shall be accompanied by detailed production records available for statistics and queries at any time" (see 5.9.3.9 to 5.9.3.14);

- a subclause "Monitoring system" has been added (see 5.9.5);

- the test of the energy consumption of the complete plant and of the power of the main mechanisms has been deleted (see 6.4.5 of the 2005 edition);

- the range of the number of verification scale intervals n has been changed (see Table A.1; A.1 of the 2005 edition);

- the title of the subclause on the calculation of the scale interval has been changed from "actual scale interval" to "verification scale interval" (see A.3.13; A.3.13 of the 2005 edition);

- the record form for the test of the energy consumption of the complete plant and of the power of the main mechanisms has been deleted (see Table E.13 of the 2005 edition).
