The sand washer assembly consists of a motor stirrer unit, glass wash beaker, cleaning brush, metal stand, siphon tube and control box. An extra beaker is provided to enable the second test to be carried out concurrently within the settling and drying periods of the first test. The metal stand is designed to accommodate the wash beaker during the agitation period of the test and the siphon tube allows the clay/water suspension to be siphoned off, after the settling periods, without disturbing the sand grains in the beaker. The control box provides an essential means of timing and controlling the agitation and settling periods. It incorporates an alarm buzzer as well as a facility for by-passing the timer and allowing the stirrer to run continuously.

The potential for hydrogen in substances is measured by the pH scale, which runs from 0 to 14. Seven on the scale is neutral. A pH that is 0 to 7 is considered more acidic, with 0 being a high level of acidity. A pH in the range of 7 to 14 is basic, or alkaline, with 14 being at the highest basic level. Pure sand is mostly made from silica, a substance with a neutral pH of 7. But pure silica is rarely found outside laboratory settings. Sand in your garden or for sale in garden centers will have other materials mixed in. These can include living organisms, vegetative matter, even water, and salts. All these things affect the pH of what is recognized as sand.

Mechanism:

Clay Washing along with automized cycle, microcontroller based electronic control box.

Misc Spec.:

Auto Clay washer conducts clay washing cycles automatically. The Number of cycles and washing time can be set by the user. It eliminates The need of Siphoning out water manually and other major manual interventions such as time punctuality for siphoning etc, ensuring The accuracy of readings.

Sand Type:

Silca Sand,

Application:

To check Total clay contents of sand sample
