Should come with a warning not to use on a 325 Watt stand mixer. It killed our machine after properly triple grinding of only one cup of wheat. Called Kitchen Aid and they didn't want to know anything about imdentifing my loss. Had to buy another machine. Bought the 575 watt pro version. Hopefully that works.
Glycerine is more commonly called glycerol, which can add to confusion because of the similarity between the terms "glycerol" and "glycol." Glycerol is a by-product of the production of soap and the refining of vegetable oils and biodiesel fuel. It is a humectant, which means it attracts, absorbs and retains moisture from the air.
Concrete production is a large scale process that involves high energy consumption. In order to increase the sustainability of this process, the reduction of energy input is necessary. Bio-glycerol was demonstrated to be a highly efficient renewable-based additive in the grinding …
In this paper, the effect of citric acid on the hematite was studied and the mechanism was analyzed. The results indicated that under the condition of the optimal grinding medium, compared with the result without citric acid added, with citric acid added at the mass of 0.10% of the hematite, the content of-0.074mm of grinding production was increased by 7.11%; physical adsorption and chemical ...
