of the machine. This enables the attendant to adjust screen cloth tension and check the unit's condition and operation. Allow sufficient clearance in front of the screen at the discharge end, or in the rear at the feed end, for replacing screen sections. A suggested clearance would be at least one foot longer than the longest screen panel.

The automatic sand sieving machine has been designed mainly for dry sand of size between 0.9mm – 0.01mm. The operation of this machine is very straight forward, simple and does not require any special expertise, skill or knowledge. To set up the machine for operation: i. Fill the sample of sand into hopper through the funnel.

Screening separates the sand and gravel into different size ranges. Water is sprayed onto the material throughout the screening process. After screening, the sized gravel is transported to stockpiles, storage bins, or, in some cases, to crushers by belt conveyors, bucket elevators, or screw conveyors.

Particle size reduction, screening and size analysis Objective This laboratory examines the particle size reduction of silica sand using manual and automatic grinding methods and the subsequent separation and size analysis of the obtained polydisperse powders. The particle size of the powder samples will be determined using sedimentation and image

In granular deposits, it is useful to remember that if all the sand grains are visible to the naked eye, then the material is entirely sand. If individual particles are invisible, the sample is classified as silt or silty sand. Gravel may be described as rounded, irregular, angular, flaky or elongated.
