HN-CY Large Coal Sampling Machine

Main features of coal sampling machine:

Fully automatic sampling, sample preparation, and ensuring the authenticity of the sampled samples.

The computer randomly selects sampling points to ensure the fairness and impartiality of sampling.

The spiral blade lifting and motor-driven spiral drill sampling head of the sampling head can adapt to full section and various raw material sampling.

Computer on-site dynamic monitoring, Chinese operation interface, easy to operate.

There are various operating modes, which can be divided into fully automatic, semi-automatic, and manual working modes.

The system has a simple structure, reliable operation, easy maintenance, and convenient repair.

Workflow of Coal Sampling Machine

The sampling process can be divided into:

Auto automatic positioning → Random selection of sampling points → Sample collection → Sample collection

After the coal transport vehicle enters the sampling area, the car and train positioning systems detect the location of the vehicle, obtain the plane coordinate parameters of the car carriage in the sampling area, and transmit them to the main control computer. The main control computer automatically generates several random sampling points in the vehicle area based on the carriage parameters. The main control computer controls the mechanical sampling device to take samples at designated sampling points, and controls the sample preparation equipment to automatically complete the crushing and reduction of coal samples.
