To solve the problems occurred during manual coal sample preparation,such as low work efficien-cy,high labor intensity,poor working environment,harmful to human beings and poor representativeness of the sample due to large error,the auto coal sample preparation system was designed.Performance tests like residue sample mass,fuel size,residue sample precision and sample preparation bias verified this system has met the requirements of GB/T 1 9494.3-2004 and GB 474-2008 on precision and bias.Its application not only improves the automation degree of sample preparation,but also reduces human disturbance factors in the sample preparation process.
