Mo­bile Sand Wash­ing Plant to Make Man­u­fac­tured Sand

NBM&CW - - NEWS -

Ur­ban de­vel­op­ment is the key in­di­ca­tor of the growth of the In­dian economy, and construction – both in­fra­struc­ture and real es­tate – play a key role as a gauge and mea­sure of growth. Sand, the back­bone of the construction in­dus­try, has be­come a prob­lem­atic re­source to pro­cure in India. Avail­abil­ity and in­fe­rior qual­ity have both con­trib­uted to the price volatil­ity in this re­source – clas­si­fied as a mi­nor min­eral un­der the Na­tional Min­eral Pol­icy in­sti­tuted in 1993. With the prob­lems as­so­ci­ated with sand, namely il­le­gal min­ing by sand mafia, heavy price volatil­ity, in­fe­rior qual­ity and non-grade ma­te­rial, high de­mand to spurt growth, sand is noth­ing less than a crit­i­cal min­eral of very high value. Whether a river sand min­ing ban by NGT, or a state gov­ern­ment regulation to op­ti­mally dredge the rivers, the prob­lem with sand sup­ply can­not be re­solved by only in­sti­tu­tional regulation. The in­dus­try needs an an­swer to the un­der­ly­ing sup­ply side prob­lems.

The most trusted al­ter­na­tive to sand is Man­u­fac­tured sand (also known as M-sand). This technology helps al­le­vi­ate the risks as­so­ci­ated with nat­u­ral sand pro­cure­ment. By de-risk­ing the construction sec­tor from heavy price volatil­ity, de­pen­dence on il­le­gal sand sup­ply – man­u­fac­tured sand pro­vides un­in­ter­rupted sup­ply and con­sis­tent qual­ity, which no in­sti­tu­tion re­lated to the nat­u­ral and river sand reg­u­la­tions has been able to de­liver.

Man­u­fac­tured sand as a con­cept, has many man­i­fes­ta­tions in the cur­rent In­dian mar­ket. Un­washed quarry dust, crusher dust (both 2&3 stage) is be­ing passed by that name. To take care of the ex­ces­sive ul­tra­fines/silt in the so-called Sand, clean­ing sys­tem has been in­tro­duced. Many such in­tro­duc­tions like bucket clas­si­fiers and screw clas­si­fiers have, how­ever, failed to de­liver on the prom­ise. These old age tech­nolo­gies can nei­ther pro­duce cor­rect sized prod­uct nor are the prod­ucts free from dele­te­ri­ous slimes & silt to the re­quired ex­tent. An­other ma­jor draw­back of these plants is their in­abil­ity to han­dle vary­ing feed types. The only re­li­able technology to pro­duce man­u­fac­tured sand is a highly

Combo 7-in-1 Mo­bile So­lu­tion for washed man­u­fac­tured sand

CDE is the world leader in ma­te­rial wash­ing equip­ment, pro­vid­ing novel means to save our planet by pre­serv­ing its re­sources. The com­pany has ex­ten­sive ex­pe­ri­ence in pro­duc­ing high qual­ity man­u­fac­tured sand in num­ber of coun­tries around the world and have suc­cess­fully in­stalled more than 200 wash­ing plants in India mak­ing man­u­fac­tured sand a pre­ferred op­tion in 30 cities across India.

CDE’s flag­ship Combo sand wash­ing sys­tem de­liv­ers washed, de­wa­tered, and well-graded Zone II con­crete sand. This is RMCready, im­pu­rity-free, vastu-friendly sand that is be­ing read­ily used for man­u­fac­tur­ing low-cost higher dura­bil­ity con­crete.

Combo de­notes the word ‘com­bi­na­tion’ of 7 func­tions of green wet pro­cess­ing technology that will save wa­ter, land, and en­ergy and not cre­ate pol­lu­tion haz­ards at pro­ject site.

The com­pact plant in­cor­po­rates all the ac­tions in­volved in wash­ing process e.g. screen­ing, clas­si­fi­ca­tion, de­wa­ter­ing, wa­ter man­age­ment etc. in a sin­gle chas­sis. This en­ables the plant to be in­stalled in a small area with at­ten­dant ad­van­tages of lower power & wa­ter con­sump­tion and thus, low op­er­at­ing cost.

chal­leng­ing tech­ni­cal process in­volv­ing wash­ing and grad­ing of sand. CDE is the pi­o­neer of this con­cept and a global leader with its cut­ting-edge sand technology op­er­at­ing across the planet. This technology uses quarry dust, crusher dust or river-bed ma­te­rial as the raw/feed ma­te­rial to pro­duce the high­est qual­ity ready-to-use graded sand, meet­ing Zone II qual­ity spec­i­fi­ca­tion un­der IS 383 for the construction in­dus­try. In CDE technology along with Zone II grade con­crete sand, some amount of Zone IV sand for plas­ter can also be pro­duced. The pro­duc­tion lev­els would de­pend upon feed ma­te­rial char­ac­ter­is­tics. Re­cently, CDE has also de­vel­oped a technology for us­ing the re­jected sludge of sand plant for mak­ing bricks.
