Batching is the process involves in measuring concrete mix ingredients by either mass or volume and pouring ingredients into the mixer. To produce a uniform quality concrete during manufacturing process, the ingredients must be measured accurately for each batch. There are two types of batching. 1. Volume batching.Web

The manufacturing process of this aggregate involves agglomeration in a slightly moist environment on an inclined rotating pan. The resulting pellets (10–14 mm in diameter) are then dried and subsequently fed into a rotary kiln or grate furnace, at temperatures between 1100°C and 1200°C, at which a degree of bloating occurs, resulting in a ...Web
