The automatic iron ore sampling and sample preparation system in the mining sector comprises a process sample sampling and sample preparation system and a bench blasthole sample preparation system. Relying on robotics combined with complete-set automated control, it achieves fully automated operations across the entire process—from sampling, receiving, preparation, and testing to warehousing—for iron ore samples.

Process Sample Sampling and Sample Preparation System:

It can perform full-section sampling and sample delivery for process samples, as well as sampling of sticky ore and preparation of externally manually delivered samples.

The sample preparation section adopts a combination of robotics and equipment to achieve automatic particle size determination and automatic moisture determination, and uploads the testing data to the system. Meanwhile, through processes such as crushing, proportional division, and grinding, the system prepares compositional samples of the required particle size, which are sent to the automatic assay analysis system via a pneumatic conveying system; retained samples are packaged, coded, and delivered to the intelligent storage system.

Bench Blasthole Sample Preparation System:

The system adopts a combination of robotics and equipment to automatically receive bench blasthole samples and simultaneously identify sample information. The robot performs operations such as proportional division, pre-drying, crushing, and grinding according to a preset procedure to prepare compositional samples of the required particle size, which are sent to the automatic assay analysis system via a pneumatic conveying system.

This automatic sampling and sample preparation system adopts an advanced, mature, and reliable process flow. Its testing data can guide ore dressing operations and bench production, and provide a basis for iron ore settlement, thereby improving the advancement and reliability of automated quality inspection and control for ore.
