A cross-over sampler at a discharge allows sampling from a vertical stream of a falling product. Sampling is usually carried out in places of material transfer from one moving conveyor to another. The equipment allows sampling of various ores, coal, charge, limestone, sand, rubble, gravel, concentrates and other bulk materials as representatively as possible in conditions where installing sampling systems directly from a conveyor belt is impossible.
Depending on the task, the crossover sampler can take samples in one or several stages. The cross-over sampler is installed directly at the transfer site and has a special bucket passing through the flow of falling material at a given speed and frequency. This allows you to sample material from the entire stream and to ensure maximum representativeness of the sample. The design of the sampling bucket engine allows you to control its movement and return to its original position.
Single-stage bulk material sampling system - the exit trough of the primary sampler is connected to the sampling container, in which the entire collected product accumulates.
Multistage bulk material sampling system - the selected product gets to the belt feeder, which forms the product flow for the subsequent stages of sampling, crushing and cutting. At the same time at these stages it is possible to use both pendulum samplers and cross-section samplers.
