apr 27, 2013 artificial sand:: natural sand are weathered and worn out the artificial sand produced by proper machines can be a better substitute to river sand.the sand only sand manufactured by crusher is cubical and angular in shape.sand made by flaky and angular particles may produce harsh concrete, and may result in mm are used, to replace the river sand.
It is best machine for making sand from stone. sand manufactured by vertical shaft impactor is of cubical shape. such sand can be used for all types of construction work, concreting, plastering etc and is better substitute to river sand. v.s.i. crushers is a most economical machine for crushing stone in cubical shape and manufacturing

dec 01, 2020 the explosively growing demand is generating a huge number of spent lithium-ion batteries, thereby urging the development of cost-effective and environmentally sustainable recycling technologies to manage end-of-life batteries.
today, only energy-intensive metallurgical methods are in place to recycle used batteries and scrap materials from battery production, and even these are limited to the recovery of elementary metals. this way, profitability can only be achieved for metals like nickel, cobalt, or manganese.
mar 16, 2018 less than of lithium-ion batteries around the world are recycled, chen said. the batteries from used smartphones and laptops often end up in
On the other hand, the used lithium ion battery contains a considerable grade of lithium, cobalt, nickel, manganese, aluminum, copper and other metal elements, some of these metals and their chemical products are relatively expensive, so if the used lithium ion battery can be scientifically and effectively recycled, it can not only effectively solve the plight of resources and the environment, but also create
sep 15, 2020 because the batteries are inexpensive, there is little incentive to recycle, so only about of lithium-ion batteries are recycled, He said.
It is proposed that BN nanoparticles formed during the milling process act as nucleation sites for growth during annealing process. apart from them, contaminant Fe nanoparticles introduced during the milling process also served as catalyst for the growth. however, the quality and purity of bnnts grown by ball milling was not satisfactory.
the mechanochemical synthesis of functionalized silicon nanoparticles using high energy ball milling is described. this method facilitates the fragmentation of mono crystalline silicon into the nanometer regime and the simultaneous surface functionalization of the formed particles.
oct 07, 2020 ball-milling technique has been used by researchers to produce uniform & small-sized iron oxide nanoparticles and their different propertiesactivities have been tested already 77, 78. apart
nanoparticles are de ned as having a particle size of 1000 nm. Th drug is present in the dissolved, entrapped, encap-sulated form or is attached to the polymer matrix 1,5. nanoparticles er several advantages. Th ey can deliver wide range of drugs hydrophilic as well as hydrophobic, can be administered via the oral
synthesis is majorly classified into two types. 1.top down approach bottom up approach top down approach is a method in which we cut a bigger part into smaller parts to a size of nano meter. all physical methods of synthesis are considered
