7 Steps in the Aggregate Manufacturing Process

Aggregate is an important raw material in the infrastructure construction industry. Aggregate is divided into fine aggregate (commonly known as sand, with a particle size between 0.15-4.75mm) and coarse aggregate (commonly known as stone, with a particle size between 4.75-9.0mm).. The aggregate material is loose and granular in shape and is the basic raw material for …

Four Types of Aggregate Conveyors

Aggregate conveyors are typically used in mining and quarrying applications as well as at storage locations and for loading and unloading. They are sized for the required tons per hour and to fit the space available. For long life, high reliability, and low running costs, the conveyor should suit the type of aggregate being moved.

Alternative fine aggregates in production of sustainable concrete …

There are several restrictions on illegal river sand mining that enforced researchers to use alternative materials as fine aggregates in construction without negotiating with quality (NGT report, 2016; Construction and Demolition waste mangement rules, 2016).
