FIELD: mining.SUBSTANCE: invention refers primarily to mine-mill industry in part of operating procedure and equipment development and may be used during pulp sampling in quality control system for products preparation for analysis. Pulp flow sampling method includes installation of slot-type sampling device to sampled pulp pipeline using mating flanges, pulp flow supply to reforming chamber of slot-type sampling device and taking primary sample using slot-type shutoff device. After pulp flow delivery to reforming chamber, pulp flow is reformed to horizontal average flow directed to expansion chamber. Pulp average flow is used for continuous taking of primary sample supplied through inlet chamber and sample outlet branch to feeding funnel of sample reducing module. Reduced sample taking is performed using cutoff-bucket, reduced sample from cutoff-bucket is directed to flow reducer, in which after mechanical mixing of flow on homogenisation disk flow is reformed to vertical down flow through homogenisation chamber, and then - to annular flow directed to reducing chamber walls outgoing from reducing disk, and controlled continuous taking of final reduced sample is performed from pulp annular flow.EFFECT: obtaining final reduced accumulated sample with minimum error.3 cl, 3 dwg |
