Aggregate Plant processing the key process analysis

Aggregate Plant processing, a focus : the stone at stone crushing vertical impact crusher of 20 - 40mm.5 to 20 mm aggregate , sand production, and can be used for shaping equipment to produce high - quality cube gravel .

(1) Coarse aggregate content of needle -chip volume control

Concrete quality requirements of coarse aggregate , coarse aggregate of needle -chip should be less than 15% . Artificial compound , the production of limestone materials processing of raw materials in the stone particle content flakiness easily exceed the specification is less than 15% of the range , so to be taken reliable measures to reduce the content of the coarse aggregate of flakiness particles in the process design , coarse crushing with a jaw crusher , but the subsequent crushing equipment selection crusher , can effectively reduce the flakiness content broken products , excellent product grain shape , so that all levels of bone material flakiness content control in the range of < 15% .This is to ensure the quality of the concrete is very favorable .

Vertical impact crusher stone at stone crushing 20 - 40mm.5 - 20mm aggregate , sand production , not only for shaping equipment to produce high - quality cube gravel , while at the same time for the sand making equipment , there are more high into the sand ratio , and is easy to pass the line speed of the adjustment device to adjust the size distribution to ensure that the needs to meet a variety of aggregate .

(2) Finished sand fineness modulus control
Tender documents require the finished sand fineness modulus of 2.4 to 2.8 , calculated according to the vertical crusher broken curve (like rock ), the fineness modulus of sand production is approximately 3.1 , the system take the following process measures to ensure the finished sand fineness modulus :
Reasonable to set the screen aperture , to ensure that the two screening stations out of the sand fineness modulus qualified to ensure the stable quality of the finished sand .
