Cemax teChnologyFosroc has developed Cemax – A unique product solution which focuses on adding value to cement production, considering all aspects relating to cement manufacturing process. Fosroc’s Cemax works in number of different ways to improve the efficiency and effectiveness of grinding action during production and providing important application benefit in terms of Flow, Compressive Strength and Consistency of finished product.

Cemax ... Works as “GRINDING AIDS & PERFORMANCE ENHANCERS” to meet various objectives of cement plants for their comminution process like Cement Mill, Raw Mill and Coal Mills.

Fosroc’s Cemax range of grinding aids and performance enhancers can save up to 40% of grinding cost.

Cemax produCtsGrinding Aids for Cement MillPerformance Enhancer/Quality Enhancer Special additives like Raw mill and Coal mill grinding aids

Benefits to Cement manufaCturers?Grinding Aids

Increased mill output Improved particle size distribution Improved Pack Set Index (flowablity)

Performance enhancer/Quality enhancer

Improved strength of cement Improved desired quality of cement Increased mill output Improved cement Pack Set Index (flowablity)

Special Additives

Improved cement properties

Benefits of Cemax teChnology...Reduced agglomeration

improvements in: energy consumption, cement fineness and mill output

improved consistent quality of cements with Better flow characteristics

improved particle size distribution

increased strength

increased composites addition rate in the cement

improve setting time, especially incase of PPC and PSC

Mechanism of agglomeration

Cement particles agglomerate between each others due to static charges

Re-agglomeration continues during grinding process

Cemax grinding aids

Cemax solution to reduCe agglomeration in Cement grinding

BenefitsReduced agglomerationIncreased mill output Reduced cement Pack Set Index (improved powder flowability)

Grinding Aid Actions

CEMAx is an organic compound that mostly active in the mill through adsorption on the particle surfacesIt generates a very thin monomolecular film around the

particles which soften some electrovalence bonds as well as neutralize electrostatic charges on the particle edges

Electrovalences of its organic group component act on the calcium (Ca++) and oxygen (O–) bond. Ion formed by CEMAx, (OH-(CH2)n) neutralized all electrostatic charges on the clinker and cement particles which eliminate coating and provide higher fluidity of the ground materials

BenefitsIncreased Mill outputReduced production cost per unit of cementImproved cement flowablity/ Reduced Pack SetImproved Mill equipment Performance

valuesImproved Mill EfficiencyReduced recirculation loadReduced blockages in Diaphragms and gridsReduced Equipment wear and tearReduced Silo outlet blockages and cakingImproved cement transportation efficiency

Cemax performanCe enhanCers

introductionPerformance enhancer improves clinker

grindability and cement quality by advanced chemical reactions

It is a second generation of cement additivesMore and more companies now prefer to use

Performance enhancer depending on the local cement market requirements and maturity

BenefitsEnhanced cement qualityReduced agglomerationIncreased mill outputReduced cement Pack Set Index (improved

powder flowability)

BenefitsImproved cement quality by solving the following Low quality clinkers New requirements from customers and marketImproved plant profitablity by producing

cement with lower clinker contentIncreased cement mill output

valuesReduction in Equipment wear and tearProducing better and unique type of cementReduction in Co2 emission through clinker replacementImprovement in plant operation similar to the effects of grinding aids

CeMAx – Grinding Aid Advantages

CeMAx moleculesadsorb onto newly

formed cement particles, reduces agglomeration.

Individually, CeMAx molecules enhance cement performance according to specific

requirements.

Performance enhancer Actions:

Higher early Strength and Faster Setting Time Optimization of the particle size distribution Acceleration of the hydration of C3A, CEMAx

accelerates the formation of Ettringite as well as its transformation into monosulphoaluminate to improve cement early strength.

Reduce Pack Set index (Improve cement dry flowablity) Ion formed by CEMAx neutralized all

electrostatic charges on the clinker and cement particles which eliminate coating and provide higher fluidity of the ground materials.

Higher late Strength Accelerate the hydration of ferrite phase,

Later, it leads to the promotion of silicate phases hydration which lead to better late strength enhancement.

CeMAx – Performance enhancer AdvantagesThe FUTURE is insight……….

Reduces production cost and improves cement plants profitability.

Improves cement physical properties which will improve cement quality and allow higher clinker replacement.
