River gravel sand making machine is typically used in the current artificial mechanism of sand making industry. It is the alternative equipment of rod mill, traditional sand maker, cone crusher etc. River gravel sand making production line is composed of vibrating feeder , jaw crusher , sand making machine, circular vibrating screen , sand washing machine, belt conveyor etc.
River gravel introduction
River gravel is usually the rock fragmentation after long-term weathering, and then by the impact rolling mill, lose angular, because often in the river, like egg shape, named river pebbles.
River gravel is a kind of natural stone material, and the main chemical composition is SiO2, followed by small amounts of iron and manganese trace, copper, aluminum, magnesium and other elements and compounds.
River gravel sand making machine
River gravel sand making machine takes use of the high-speed rotating materials mutual to crush suitable for hard, medium hard and abrasive materials with coarse crushing and fine crushing process. River gravel sand making machine is applied widely for crushing iron ore , copper ore, gold ore, lead-zinc ore, tungsten ore, manganese ores, building sand, corundum slide pink, olive, salt, fluorite, limestone and silicon carbide slag etc.
When the sand making crusher’s discharge product size is not greater than 10mm, the qualified rate is 60% ~ 90%, in order to ensure product size pass rate reached 100%, with grading equipment closed circuit crushing is necessary. River gravel sand making machine can also be used for rough grinding operations, when the crusher’s feed particle size is 2 ~ 8mm, the particle size of up to 0.149 to 0.92mm.
River gravel sand making machine advantages
River gravel sand making production line a high degree of automation with low operation cost, high crushing rate, energy saving, large output, less pollution, simple repair, production of machine-made sand in line with national standards for construction sand, uniform particle size, particle shape, reasonable gradation.
River gravel crusher and sand crusher
Jaw crusher is the primary crushing equipment in the river gravel sand making production line. NFLG can supply you PE series jaw crusher and JCE series jaw crusher in the sand making plants, rock quarry plants, stone processing lines etc. gyratory crusher (cone crusher) can be used as secondary crushing equipment for river gravel sand fine crushing process.
