Apr 09, 2014 Use of Conveyor belt in Mining industry and food industry. Minimum labour is required for the operation and maintenance of belt conveyor system.Many other functions can be performed with the basic conveying like weighing, sorting, picking, sampling, blending, spraying, cooling, drying etc.
required size sample. Stop the conveyor belt and clean off a section of material from the belt. Insert a template that conforms to the shape of the belt. Carefully remove all the material from the template. Use a scoop to remove as much of the material as possible. A brush and dustpan may be used to remove the fine material.
4.3.1 Sampling from a Flowing Aggregate Stream - Samples shall be selected from all of the material produced using CP 75. Use extreme care to avoid segregation when sampling. Sampling the initial discharge or the final few tons from a bin or conveyor belt increases the chances of obtaining segregated material and should be avoided.

The Construction Manual lists the following sample locations in suggested order of preference Conveyor belt between the weigh hopper and the central mixer or transit mix truck Conveyor belt feeding the batch plant bins immediately preceding the weigh hopper
Oct 05, 2007 SAMPLING CONVEYOR BELTS When sampling conveyors the following guidelines should be observed For conveyors that are discharging current production, sampling a single cross section of it is considered acceptable. For conveyors discharging material from a loader or truck feed bin or hopper, segregation will influence results more so
6.1.3 Sampling from a Flowing Aggregate Stream (bin or belt discharge). Definition of the sublot and location of the sampling unit is generally identical with sampling from a conveyor belt, with the exception that the sampling unit in this case is defined as that material which will flow during a five minute period.
D75 also allows the use of sampling tubes to sample a stockpile at random locations. Carefully collect the entire contents of each shovel or scoop full into an appropriate container. Conveyor Belts-Conveyor belts are often considered the best source for representative sampling during aggregate production. The process involves collecting three ...
Belt Widths The belt widths are as follows 18, 24, 30, 36, 42, 48, 54, 60, 72, 84, and 96 inches. The width of the narrower belts may be governed by the size of lumps to be handled. Belts must be wide enough so that any combination of prevailing lumps and finer material does not load the lumps too close to the edge of the conveyor belt.

a belt clamp, mounted on the conveyor structure, through which the belt is threaded. Where the slope is very long, additional clamps should be spaced approximately 1000 feet apart. Where more than one clamp is used, workers are stationed at each clamp to loosen and tighten the clamps as the belt is fed onto the conveyor. Care must be
discharge points and conveyor belts can be widened to be more forgiving (e.g., skirting internal back-to-back width can be reduced to allow the belt more side travel.) Skirting should be extended a minimum of three belt widths past the load point. Rules for conveyor and load point
