• The Aggregate Manufacturing Process General Kinematics

    Most of the products we use every day are made with feldspar, the most abundant group of minerals in the earth’s crust. Feldspars play an important role as fluxing agents in ceramics and glass production and are also used as functional fillers in the paint, plastic, rubber and adhesive industries. Granite, formed from quartz, feldspar, micas, and Aggregate ProcessingGeneral Kinematics Processing EquipmentDuring processing, aggregates are distilled down to a level of their most common use. Some aggregates may be crushed to a powder while others may be screened to various diameter chunks. The proper processing of aggregates is important in maintaining their desirable qualities. For instance, between 60 and 75 percentof concrete consists of both coarse and fine aggregates. If the aggregates are not properly sized, as well as clean and free from other matter, the concrete could fail to meet its desired strength a

    How Concrete is Made In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
