The first is by collecting the cross section from the falling coal stream at a transfer point between two conveyors. This is known as CrossStream Sampling. The second method is by collecting the primary increment by sweeping the cross section from the material on a single conveyor belt. This is known as CrossBelt Sampling.
Central belt sampler. The central belt sampler is used in the middle of coal conveyor belt. The main character of the central belt sampler is scrape sampler. The scrape sampler cuts the moving coal stream crosswise. The central cross belt sampler has a simple structure, and the mass of the single sample is smaller.
In the field of industrial sample taking and sample preparation of bulk materials and suspensions of all kinds we are planning and produce sample taking and preparation plants tailormade for your requirements. Representative sample taking from the moving product flow, from conveyor belts, from chutes and slides and from piping systems.
Falling Stream Sampling Systems. Falling Stream Samplers are a general product category that covers a wide range of sampler designs. The key characteristic all these designs have in common is that sample material is collected from a main process flow that is either in a freefalling condition or traveling through some trajectory, such as at the discharge of a conveyor.
You can choose the separate machines or ultimate sampling system according to your requirements. Why choose TOP Sampler sampling system machines? As a sampling system manufacturer from China, the lower price is our biggest advantages. Secondly, our sample preparation machines have coal sample storage, automatic washing, and rainproof function.
