Iron Ore Sampling Systems High rigidity Sampling

Sep 10, 2018  For the iron ore concentrate, the GBT-10322.1-2000 standard stipulates we can use the auger sampling system to sample unless the auger sampler can reach the bottom of the iron ore storage and the auger hopper which is filled with iron ore. TOP-SAMPLER promises that our all sampling systems can meet this requirement and the sampling procedure is random and effective.
