Description
The PRV type sample-taker allows you to recover batches of material in a vertical drop without modification of particle size or shape. The material is removed by the rotary spoon and then conveyed inside the DN100 cylinder fitted with an internal thread. The whole is rotated by a gear motor. The gravity recovery of the sample is carried out at the outlet of the DN 100 cylinder on an inclined sheet allowing the filling of a volumetric chamber, the surplus returning to the strains.
