1 Scope

GB/T 25701-2010 is the Chinese national standard on single toggle jaw crusher - specific metal consumption, 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 23 December 2010 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 July 2011. Classification: ICS 73.120, CCS D94. 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 commentary compound pendulum jaw crusher metal consumption of terms and definitions, technical requirements, test methods, metal crusher unit consumption Fixed and metal consumption rating labels. This standard applies to compound pendulum jaw crusher (hereinafter referred to as crushers).
