  • Chute Cross Cut Sampler Multotec

    Chute cross cut samplers, widely used in coal, iron ore, sands, diamonds, base and precious metal industries are suitable for a wide range of applications from light duty (HM sands) to heavy duty (coal export terminals) models Their heavy duty rugged construction is integrated into the chute crosssection or mounted on the head boxCoal Sampling By Cross Cut To sample a fine freefalling stream sampling a conveyor belt with a crossbelt cutter as depicted a sampling cup shall be used with the minimum dimensions as given in figure below in addition the length of the cup should be at least three times the width of the falling stream to be sampled and the edges of the opening must be sharp to ensure a clean cut More Coal Sampling By Cross Cut thaiphysiodeA channel of uniform crosssection is cut manually into the coal seam, and all the coal within the cut section is collected on a plastic sheet placed at the base of the channel Most channels are around 10m across and samples should not be less than 15kg per meter of coal thicknessCoal sampling techniques for different seams ~ Learning   One coal sampling from the truck method is diagonal sampling by the coal trucks, we also called that threesamplingpoint sampling method The beginning point and end point should be set in a position which away from the truck 5 meters, and the third point should at the center position Then digs 04 meters and samples the subsampleCoal Sampling Methods Ensuring the Representative of perpendicular to the coal flow It cuts a swath through the coal and throws a sample into a chute The coal sample is taken via the chute to the analysis equipment The high inertia scoop must be accelerated to full speed within 90 degrees rotation to insure it will have enough power to cut through the coal as it travels along the conveyor beltCross Cut Sampler For Coal
