Description :

• Mineral Grind plus is one of the latest innovation by Vista in the field of grinding Aid for mineral, Cement raw material, Coke, Coal, Calcite, quartz, dolomite etc.
• The above mineral grinding involves rather higher power consumption than that stipulated in Ritinger's law in chemical engineering discipline, because of coating of powder on hammers, balls, rollers, interior mill surfaces and due to re-agglomera-tion /re-adhering of freshly fractured particulate minerals during and post size reduction operation. This phenomenon reduces powder flow bility/dispensability to a great extent increasing unit grinding cost.

Advantages :Vista mineral grind plus when added by mass of grinding feed offers thefollowing :

• Increase mill output (6% to 12%) depending on the efficiency of the grinding
• installation & the characteristic of raw meal to be ground
• Increase fineness for same energy input.
• Reduces grinding energy cost due to lesser power consumption.
• Improved flow characteristic of feed during grinding and storage.

Dosage : Can vary from 0.03 to 0.1% by mass of charge depending on hardness, microstruc-ture, and re-agglomeration characteristics of minerals

Dosing equipment :

• The additive should be accurately dosed by means of a calibrated dosing pump.
• Vista's technical team arranges installation, and operation of dosing pump at site.

Gypsum, limestone etc are recommended to determine initial blend proportion, grinding efficiency , mortar flow, pack set index, and compressive strength of cements at varying dosage to work out the most economic dose level. Cement mill trials should follow to finalize continuous use of this additive.

Dosing equipment : Vista Catasoft C- 88 should be accurately proportioned through a calibrated dosing system. Vista's technical service wing is ready to assist the customer

Addition rates :

• Typical dosage rate may vary from 0.05% - 0.10% by weight of cements including Portland

Description :

• Vista Combustion Catalyst (VCC) is an innovative chemical. When added tcoal (peat, lignite, bituminous) , coke or agrfuels- Bagasse, rice husk, jute waste.
• It helps in proper burning texplore maximum heat value of fuel reduces ash depo-sition and fouling of boiler tubes, hot air duct, chimney etc.
• VCC catalyses the combustion by generation of active oxygen which accelerates oxidation of carbon, hydrogen, hydrcarbon, and cellulosics. This results in com- plete combustion and increase in heat OUtPUt per unit of fuel burnt. When opti- mized saving in fuel consumption economises fuel bill tthe extent of 10 -20%. As coal deposit is fast depleting saving not only preserves resources but reduces emis- Sion of green house gases ( C02, NOx, Sox) responsible for global warming. In addi- tion use of VCC reduces burn-out, devolatalization, slagging and fouling of com- bustion units of all types operating with coal & other solid fuels.

Composition : VCC is based mainly on manganese salts  supported by activator (promoter) Chemistry of combustion when solid fuels are burnt, the moisture reacts with carbon tgenerate valuable C(carbon monoxide) and hydrogen. The burning of the former gases is made  fast by VCC.The fixed carbon (C) and volatile hydrocarbons require sufficient supply of oxygen from air. Since air is composed of only 21% oxygen and 79% nitro-gen (inert gas). The active oxygen produced by VCC in-situ. Catalyzes the system. The Oxidized atmosphere is generate by reduction of manganese compounds Mn+7 + 5e → Mn+2, Mn+4 + 2e → Mn+2

Advantage :

• Reduces stock soot emission (air pollution)
• Reduces un burnt carbon in ash
• Reduces corrosion of coal burner (pulverized firing system)
• Enhances carbon- oxygen reaction
• Increases OUtPUt of kilns, furnaces, boilers
• Better heat conduction - improved burning results in coal saving (10-20%) irrespective of firing system / pulverized or otherwise.
• Cleans the system removing unwanted residues
• Minimizes work rate of blower and suction fans (power saving)
• Enhances boiler life by reducing corrosion of met allies and refractories, fouling (deposition on convection heat surface, e.g. super heaters and reheaters)

Method of application :

• Other than pulverized system of firing - The liquid catalyst can be conveniently spread over the coal charge (nut, breeze or lump ) @ 0.5% by weight of coal manually.
• Pulverized system of firing - For thermal power or other industries operating on pulverized coal firing, a dozer machine has tbe installed tdose the catalyst either at pulverizer end or on conveyor.

Area of Use :

• Brick field * Sugar mills * Textile Processing * Confectionaries/ Condiments * Glass Melting
• Cements Kilns
• Refractories/ ceramic * Teas/Coffee * Manufacture
• Producer/water gas generator * Metallurgy-smelting in Culpa, etc

Vista Hydration Promoter (VHP) is an inorganic composite made of oxides, hy-droxides and salts of alkali, alkaline earth metal and amphoteric oxides of Group IV element. It promotes rapid hydration of the glassy phases, of both Pulverized Fuel Ash (Fly Ash) and Granulated Ground Blast Furnace Slag (GGBS), Pulverized Air cured Bolder, other slag derived from Sponge Iron sector and so on, when blended with OPC (Ordinary Portland Cement) clinker to manufacture composite cements like Portland Slag Cement (PSC) and Portland Pozzolona Cement (PPC). The precise role of VHP is to assist in rapid strength development of both PSC and PPC which are very slow setting unlike OPC. Rapid hydration of both Slag and Fly Ash, being secondary cementitous materials, saves concreting cost. VHP-activated Blended Cement is also economical due to low level of OPC clinker usage. The me- chanical strength and durability of such blended cements are superior to Ordinary Portland Cement.

Application and Advantage :

• Manufacture of premium brand high early strength PSC or PPC to compete OPC in terms of strength and durability.
• Production of high strength blended/composite cement having higher loading of Slag or Fly Ash and less of Clinker to reduce unit cost of production yet maintaining the same level of strength and durability.
• VHP allows incorporation of high volume of Fly Ash reducing proportionately OPC for concrete making in Ready Mix Concrete (RMC) business. As OPC is much costlier than Fly Ash, the unit cost of RMC is reduced.
• Production of Fly Ash Bricks and Shapes. Use of VHP considerably reduces hydraulic/air curing time and quickens re-cycling of moulds; thereby increasing speed of production.
• Rapid hardening Slag/Fly Ash cement based jointing mortar and plasters, making them water proof as well. Ceramic Tile Adhesives based on PSC or PPC harden thoroughly within 10-12 hours.
• Reduction of heat curing time of cellular concrete blocks and shapes containing VHP together with Fly Ash saves energy cost.
• Asbestos cement products — incorporation of more Fly Ash amounts to cost saving and carbon credit.

Dosage : Depending upon the composition and content of slag or fly ash and nature of clinker, whether from Rotary or Vertical Shaft Kiln, dosage may vary from 0.5 to 1.5% by weight of blended cement. It is advised to fix the dosage after carrying out Laboratory Test as given in "Testing Manual" supplied with this leaflet. The product is a commercial innovation keep-ing in view the business of blended cement manufacturing units and for those using blend-ed cement as Raw Material.

Grades :

• Regular grade is meant for mini cement grinding units incorporating very high proportion of Slag / Fly Ash in manufacturing cement and which has non-structural usage like jointing mortar and plasters and similar applications, such as tile adhesives.
• Super grade is recommended where the blended cements are used for structural con- cretes only and high strength and high durability are prime requirement. It is an excellent additive to upgrade cement quality for production of premium brand blended cement of high early strength or reduction of clinker yet achieving the bench mark quality.
