Bisley has been active in the supply of raw materials to the concrete admixture industry since the early 1980's. Today the Company works both with local admixture companies and the major multinational concrete admixture manufacturers throughout North America.
The primary oxides found in the raw materials used in cement give cement its color, namely chrome, iron and nickel. These oxides, especially iron oxide (Fe 2 O 3) are kept to a minimum during production, and this gives the cement its color. What's more, the heat required for burning and the fineness is higher with white cement.

Limestone plays two major roles in the cement manufacturing process, one is used as a raw material for cement clinker, and the other is used as a cement admixture. Limestone is one of the key raw materials of cement clinker. Around 80-90% of the raw material for the kiln feed is limestone.
Ball Mill Ball mills with high efficiency separators have been used for raw material and cement grinding in cement plants all these years. Ball mill is a cylinder rotating at about 70-80% of critical speed on two trunnions in white metal bearings or slide shoe bearings for large capacity mills. Closed circuit ball mill with two compartments for ...
Cement - Composition, Properties, Major Cements: Portland cement is made up of four main compounds: tricalcium silicate (3CaO · SiO2), dicalcium silicate (2CaO · SiO2), …
The IoT sensors from Faststream Technologies collect aggregate product data and other third-party syndicated data from various stages of a product cycle. This data relates to the composition of raw materials used, temperature and working environment, wastes, the impact of transportation, etc. on the final products. Packaging Optimization:
1. Which type of secondary materials are used in the clinker / cement / concrete manufacturing? The secondary materials used in the cement industry are: Alternative raw materials (ARM), which are defined as waste materials or by-products from other (mainly industrial) processes or societal sectors and used in clinker production to substitute ...
Cement - Extraction, Processing, Manufacturing: Raw materials employed in the manufacture of cement are extracted by quarrying in the case of hard rocks such as limestones, slates, and some shales, with the aid of …
