Aggregate Grinding Mill Machine

For coarse aggregate crushing and also the fine aggregate crushing, we recommend to you personally to select BINQ JAW CRUSHER. Jaw crusher could be the most favored aggregate crushing equipment. It's construction is easy but working proficiency is high. As well it's easier to change a wear aspect and also the common check and maintenance.

About aggregate grinding, we all suggest to you to select MTW Trapezium Grinding Mill. It's improved on MTM Trapezium Mill. Both grinding mills are usually advanced than common ball mill. You can select these grinding as aggregate grinding equipment.

Coarse Aggregate and Fine Aggregate Introduction

Aggregate refers to these shed granular material filled in the concrete with the role of skeleton. It's usually named concrete aggregate whose diameter is generally more than 0. 16mm. According to the apparent denseness, aggregate is generally divided into three styles which are general aggregate, lightweight aggregate and weight aggregate (such as barite). Also, aggregate can be divided into fine aggregate and coarse aggregate by aggregate size.

Coarse aggregate includes pebbles, pebbles, crushed gravel, blast furnace slag, broken bricks, the 2nd aggregate (concrete crushing objects), and also various natural rocks (such as andesite, quartzite) or artificial calcined materials (such because brick blocks, refractory clay clinker) with special features, etc.

Fine aggregate refers to this gravel or even crushed stone material in whose stone size is less than 5MM used for planning the concrete. Fine aggregate is usually divided into coarse sand, method sand, fine sand as well as finer sand, whose fineness modulus is actually of 3. 7 ~ 3. 1, 3. 0 ~ 2. 3, 2. 2 ~ 1. 6 and also 1. 5 ~ 0. 7. According to production sources and materials, fine aggregate may be divided in to ordinary river sand, mountain sand, sea sand, artificial killed sand (stone chips), and waste sand.

Concrete fine aggregates generally utilizes clean river sand, ideal for the actual medium and also coarse sand. Coarse aggregate should properly use gravel, crushed stone or even crushed gravel according to nearby resources as well as material supplying conditions, combined with engineering and technical requirements. The maximum size of coarse aggregate should be decided according to the structure, steel spacing and construction techniques, equipment and other selected conditions.

Alkaline activity check should be taken about the aggregate used in concrete in the conditions of water, soil, open or even damp. Construction site ought to adopt nearby aggregate; Metallurgical Construction must focus on use a metallurgical slag, to limit the distance and also decrease shipping costs, create resources and waste treatment damage profits.
