Basalt Aggregate Processing Equipment

Aggregate can be produced by different stone materials. Basalt is one of raw materials for aggregate production. In basalt aggregate production operation, several processing equipment will be involved, such as crushing machine, screening plant etc.

Aggregate Production

Aggregate refers stone and other granular materials mixed with cement and water in the production of mortar or concrete. Aggregate is the loose granular material which plays the role of the skeleton or filling materials in the concrete. Gravel in concrete accounts for about 3/4 of the total volume of concrete sub-coarse aggregate and fine aggregate. Coarse aggregate includes gravel, crushed stone, slag, etc., fine aggregate includes the sand, fly ash.

It plays very important role in the construction industry, and at the time of mixing, stirring cement with water, into a thin paste, if without aggregate, it will not be forming, will lead to unusable. So in the construction industry, the aggregate is leading a very important role.

Basalt Aggregate Processing Equipment

Aggregate can be produced by different stone materials. Basalt is one of raw materials for aggregate production. The long geological, mining and technological research tends to show that the basalt ore can be cost effective for production of various products of basalt aggregates such as: basalt composites, basaltic glass, cast basalt, basalt fibers, and even jewelry whose value is similar to values of jewelry made of stones.

In basalt aggregate production operation, several basalt aggregate processing equipment will be involved, such as crushing machine, screening plant etc. Gyratory crushers, jaw crushers, roll crushers, and impact crusher are used for primary and secondary crushing. After crushing, the size of the material is further reduced to 50 micrometers or smaller by grinding, using ball mill, media mills, autogenous mills, hammer mills, or jet mills. The ground material then is classified by wet screening, dry screening, or air classification. At some plants, after initial crushing and screening, a portion of the materials can be delivered for construction sand application.

Crusher for Basalt Production

Crushing is the integral stage in basalt aggregate production operation. Basalt rock is a relatively hard mineral, generally, crushing operation can be processed by three stages: primary crushing, secondary crushing and tertiary crushing. The feeder or screens separate large boulders from finer rocks that do not require primary crushing, thus reducing the load to the primary jaw crusher. The stone that is too large to pass through the top deck of the scalping screen is processed in the secondary crusher. Cone crushers are commonly used for secondary crushing. Tertiary crushing is usually performed using cone crushers or other types of impactor crushers.
