The ITECA rotating cup sampler, also known as Type PGR, is made of a steel body, fitted into a vertical chute between two flanges. The basic working principle of the rotating cup sampler is based on a pivoting sample spoon that cuts across the entire material stream. Each sampler is customised based on the specific material being sampled with careful attention being paid to the sampler slot size in relation to the particle size distribution of the bulk material.
The speed at which the spoon cuts across the stream is based on the specific material as well as the flow rate of material. Lastly the number of cuts is also influenced by these parameters and is therefore customised for each individual application. The setup is based on the Pierre Gy sampling theory.
