GB/T 10605-2015Center driving rotary-rake thickener (English PDF)

1 Scope

GB/T 10605-2015 is the Chinese national standard on center driving rotary-rake thickener, in the field of mining and minerals. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 10 December 2015 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2017. Classification: ICS 73.120, CCS D96. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Standard specifies the product classification, technical requirements, test methods, inspection rules, marking, labeling, instructions for use, packaging, transportation and storage of center driving rotary-rake thickeners. This Standard is applicable to center driving rotary-rake thickeners used to thicken and deslime various slurries (hereinafter referred to as thickeners). This Standard is inapplicable to thickeners which have adiabatic device requirements for thickening tanks.
