Aggregate Gradation Control Unit

An Aggregate Gradation Control Unit is a piece of equipment used in the construction industry, specifically in the field of aggregate production. It falls under the supply class of Miscellaneous Construction Equipment and is categorized within the supply group of Construction, Mining, Excavating, and Highway Maintenance Equipment.

The purpose of an Aggregate Gradation Control Unit is to measure and control the gradation, or the distribution of particle sizes, of aggregates used in construction projects. This unit ensures that the aggregates meet the specified gradation requirements for a particular application, such as concrete or asphalt production.

The unit typically consists of a series of sieves with different mesh sizes, a mechanical shaker to separate the particles, and a collection pan to collect the separated aggregates. The operator places a sample of the aggregate onto the top sieve and activates the shaker, which vibrates the sieves and separates the particles based on their size. The separated aggregates are then collected and analyzed to determine if they meet the desired gradation specifications.

By using an Aggregate Gradation Control Unit, construction professionals can ensure that the aggregates used in their projects are of the correct size distribution, which is crucial for achieving the desired strength, workability, and durability of the final construction material.
