Aggregate processing plant includes Extraction, Crushing, Other Benefaction, Screening, Segregation, Stockpiling and Handling process.

Total process of aggregate processing plant from extraction through processing. Processing influences mineral quality and integrity, aggregate physical properties, and, in particular, gradation (size control).

Extraction in Construction Aggregate processing plant:

Extraction methods in Aggregate production contain Stripping, Drilling and Blasting, Shot Rock or Gravel Bank.

The vast majority of materials used in the mineral aggregate industry are obtained from surface-mined stone quarries or from sand and gravel pits.

Crushing in Construction Aggregate processing plant:

Crushing in Aggregate processing plant includes Scalping, Jaw Crusher, Cone Crusher/Impact Crusher and Vertical shaft impact crusher, Impact Crushing.

Aggregate crushing is the first step of processing after the extraction from quarry or pit. Many of these steps also are common to recycled materials, clay, and other manufactured aggregates. The first stage in most aggregate process operations is the reduction and sizing by crushing. Some operations, however, provide a step prior to crushing called scalping.

Screening in Construction Aggregate processing plant:

Screening is another technique to control both quality and gradation of the aggregate product.

The rinse screen is also commonly used. By processing the material over a screen that retains all of the product, the clay and deleterious fines may be rinsed away to make the product acceptable.

The best technique for gradation control is screening. Aggregate Screening may be done wet or dry, depending on the type of aggregate being processed and the degree of consistency required for each product.

Segregation in Construction Aggregate processing plant

Segregation begins on the belt where fines vibrate to the bottom and coarse aggregate remains on the top as the material bounces across the idlers. At the end of the belt, if left un-deflected, the coarse particles are thrown out and away. Fine particles, on the other hand, tend to drop down or if wet even follow back underneath the conveyor. The greater the speed of the belt, the worse the segregation problem is.

Stockpiling and Handling in Construction Aggregate processing plant

Although the cone stockpile is very common in the aggregate industry, two stockpile procedures may easily reduce product integrity.

A radial stacker is a compromise solution for conveyor-built stockpiles, especially if kept less than 20 ft. The proper technique is to keep the end of the movable conveyor less than a meter from the top of the pile and raise the conveyor with the pile to the full height. Then the conveyor is moved horizontally with the pile in small increments. In this manner the pile is constructed at one end while the products are retrieved at the other end.

Truck built stockpiles and layered stockpiles are also used in aggregate Stockpiling and Handling process.

Zoonyee can offer complete aggregate processing unit for the quarry plant including crushers, grinding mills, screen and belt conveyor. Zoonyee also design the aggregate process for the special stone crushing company with different capacity.
