Aggregate Crushing Solutions

Sand and gravel aggregate crushing plant design: sand and gravel aggregate is the core raw material for construction, transport and other fields, and its crushing solution needs to meet the core requirements of ‘high yield, excellent grain shape and low energy consumption’.

According to different characteristics of mother rock (granite, limestone, basalt, etc.) and production scale, the following is a comprehensive plan to optimise the processing of sand and gravel aggregate:

Sand and gravel aggregate crushing equipment selection and process matching

Rough crushing equipment

Jaw Crusher

Jaw Crusher

Applicability: processing hard rock with compressive strength ≤320MPa, feed size ≤1200mm, discharge 150-300mm, crushing ratio 5-8.

Special design: hydraulic adjustment of discharge opening, adjustment range 75-225mm, wedge type jaw plate fixing system.

Medium crushing equipment

Impact Crusher

Impact Crusher

Soft rock economic solution: ≤40mm aggregate by impact crushing, rounded grain shape and controllable powder rate (5-10%).

Technical features: three-chamber crushing + heavy-duty rotor design (500-1000rpm), impact plates can be used in both directions to extend life.

Sand making and shaping equipment

Roller sand making machine

Roller sand making machine

Finished product optimisation: process 5-30mm aggregate to 0-5mm mechanism sand, sand fineness modulus 2.6-3.0 adjustable, stone powder content ≤10% (dry process).

Wear-resistant technology: roller surface material used.

Screening and washing equipment

vibrating screen

vibrating screen

Process control: pre-screening (aggregate grading: 26-31.5mm, 16-26mm, 5-16mm) + finished screen (sand/stone separation).

Bucket wheel sand washing machine

Purification requirements: the mud content of selected sand is reduced to ≤1.0% (national standard Class II sand), and the water recycling system reduces the consumption of clean water by 50%.
