Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker
CHRYSO ® Reductis 50 reduces significantly the Hexavalent Chromium content in cement even at low dosages. It allows to maintain durably the Chromium VI content below 2 ppm
Cement Raw Mill Grinding Aid (RMGA) We produce high quality product of Cement Raw Mill Grinding Aids to help achieving high level of raw material fineness in raw mill. RMGA will improve the grinding efficiency (increase
Principal application is to increase output (tons/hour) at constant cement fineness (cm 2 /g) Introduced at low dosage, usually. between 0.01 and 0.10% (most preferably at 0.01 0. 1%) Influence on cement quality is
MasterCem cement additives amplify grinding efficiency, resulting in a higher mill throughput and lower the clinker factor, with an overall reduction in CO2

SikaGrind455 GNT is a cost effective grinding aid for portland cement and other hydraulic cements. SikaGrind455 GNT is non chloride based grinding aid. SikaGrind455 GNT
Our grinding aids are designed to increase mill output without increasing costs, while saving energy and reducing CO 2 emissions. Improved cement flowability reduces the effort for handling and transporting cement. The TAVERO® family of products include: TAVERO® VM. Optimises performance of vertical roller mills.
At the same time of the first commercial grinding aid in the cement industry, the first studies concerning grinding aids in dry grinding processes appeared in the literature [3,4]. In a first instance, it was assumed that liquid grinding aids may act by bringing static charges of the same sign to the surface of the product particles [ 3 ].
The cement grinding process is the final chance to adjust the cement quality to meet the demands set by relevant standards and cement customers. It combines influences from different areas like the mechanical grinding process, the chemical and physical raw material properties and the cement formulation itself. Interactions between these effects
Grinding aids are organic compounds that are added to the mill during cement grinding. Their main purpose is to reduce the energy required to grind the clinker into a given fineness. In addition, some products (usually referred to as performance enhancers) provide positive effect on cement hydration improving strength development [1].
Grinding aid or grinding additives refer to substances which when mixed into the mill contents cause an increase in rate of size reduction [1]. These terms are very common in cement industries where it is used to increase the throughput to the mill. Grinding aid also affect the cement flowabilitiy throughout the circuits.
Cement Raw Mill Grinding Aid (RMGA) We produce high quality product of Cement Raw Mill Grinding Aids to help achieving high level of raw material fineness in raw mill. RMGA will improve the grinding efficiency (increase
Techniques used to determine the effectiveness of these admixtures with/without grinding aids and the chemistry of early cement hydration included surface area determination, atomic absorption
affected. In particular, cement production in Spain decreased by 23% in 2008 relative to 2007.1 Due to this huge drop and the forecast for the coming years, cement producers feel obliged to take measures to drastically reduce production costs. One of the fields most affected by these costreducing measures is the grinding aids sector, which
A variety of additives have been shown to have grinding aid characteristics for grinding cement clinker. Typical among these are amines, organosilicones, glycols, resins, cod oil, kojic acid, carbon
The foreign investmentbased cement factories are found to be more efficient and profitable than the governmentowned or private cement factories, the survey revealed. In order to produce 1 tonne of cement, the foreign investmentbased factory uses 0.99 tonne of limestone on average. In contrast, the stateowned factory uses 1.45 tonnes.

Description. MA.G.A./M is a highefficiency grinding additive, normally used for increasing the mill output and improving the quality of the ground materials (granulometry and dry flowability). This concentrated additive is based on accurately selected raw materials in order to guarantee constant quality and high performance.
Antiscalants and Descalants. While scale formation can often be greatly reduced (depending on the system chemistry) by the appropriate use of BASF Solutrix™ antiscalants, (Solutrix™ 11, 11 (J) and 100) sooner or later there is nearly always a need to remove existing scale. Some scale minerals are amenable to acid cleaning and traditional

Cement grinding unit cost. Take the annual output of 600,000 tons of largescale cement grinding station as an example, there are three common options can be recommended: SCHEME 1: roller press + φ 3.2 ×13m ball mill; SCHEME 2: φ 3.8 ×13m closed mill; SCHEME 3: clinker fine crusher + cement roller press+φ 3.2 ×13m ball mill.
Addition of grinding aid to a cement mixture reduces the amount of water you might need to add to the mixture by 15%. It reduces the amount of coating that will be required; Grinding aid increases the quantity/output that will eventually be gotten from the mixture ; It expands one day strength by 1040% and 28 days strength by 520%
