Suitable proportioning pumps with adjustable flow rates should be used for consistent performance of the additive. Addition Rates The dosage rate of NRG will depend on the fineness and the reagglomeration characteristics of each cement. Typical dosage rates will vary from 0.02% - 0.06% by weight of cement for Types I & II cements and …
The average particle diameter of cement was reduced by 3.65 μm when 0.03 wt% of PC was added as grinding aid. Moreover, a high initial fluidity of the cement paste, 290 mm, could be reached when 0.08 wt% of PC was added. The fluidity loss of cement paste after 30 min and 60 min was 265 mm and 260 mm, respectively.
Our peristaltic pump is usually used for liquid cement grinding aid transfer. We always suggest the pump depends on our customer's cement grinding aid's add amount, then introduce the suitable pump.

The action of additives in cement is divided into two types: Grinding aids; Quality improvers; In the world practice of cement grinding and other solids, for more than 60 years, the theory "Adsorption-related strength decrease of solids" has dominated, this theory is formulated in 1928 by Soviet scientist Peter Alexandrovich Rehbinder.
The OPTEVA® CBA® series of additives is a new concept in grinding aids - significantly different from any previous GCP product for the cement industry. The difference is that it is a "Grinding Aid Plus". OPTEVA® CBA® additives offer all the benefits of traditional grinding aids, such as increased grinding efficiency and cement flowability. …
A molecular modified PCE-type GA was self-synthesized, and the grindability concerning grinding duration and particle size distribution of ground cement was evaluated. Setting time, flowability, hydration heat, mechanical properties and microstructure of the ground cement were also investigated. The results show that: PCE-type GA is effective …
1. Introduction. The history of grinding aids in dry fine grinding processes starts in the late 1930s with the application of the first commercial grinding aids in the cement industry [1].Since that time, the importance of grinding aids in industrial dry fine grinding processes has strongly increased; so did the number of scientific papers …

1. Introduction. Grinding aids, first introduced into cement manufacturing in 1930 [], are surface-active substances that facilitate particle comminution during the milling process.In the production of Portland cement, grinding aids are added in small amounts in the range of 0.01 to 0.10% by weight of cement, according to the PN-EN 197-1 standard [].
1. Introduction. Cement world production currently increases up to approximately 4 billion tons/year. The electrical energy consumed in cement production is 110 KW/tone and about 30% of which is used for raw material preparation and about of 40% for final cement clinker grinding [1], [2], [3].This leads to important cost increase of …
The national average hourly rate for a concrete pump truck rental falls somewhere between USD$ 400 and USD$ 750. But there's more to it than that. The size of the pump, specifically the boom length and concrete capacity, also affects the hourly rate. Larger pumps with longer booms can reach further and handle bigger jobs, so they …
