A clean and revolutionary cold manufacturing process. Hoffmann Green has initiated a technological breakthrough based on changing the compositionof cementso that it does not contain clinker, the main source of CO2 emissions in traditionalcementproduction, as well as creating a cold and cleancementmanufacturing process (no firing of raw materials).

Sep 26, 2020· The manufacturingof cementgenerally involves four steps:Mixing; Burning;Grinding; Storage;Mixing: Themixingof raw materials can be done either with dry process or wet process. In dry process the calcareous and argillaceous materials are grinded to the required size and then they are mixed in required proportions and stored in silos ...
There are four stages in the manufacture of portlandcement: (1) crushingand grindingthe raw materials, (2) blending the materials in the correct proportions, (3) burning the preparedmixin a kiln, and (4)grindingthe burned product, known as “ clinker,” together with some 5 percent of gypsum (to control the time of set of thecement).

Thegrindingif clinkers in modern plants is carried out in thecementmill which contains chromium steel balls of various sizes. These balls roll within the milland grindthe mixture which is collected in a hopper and taken in the bucket elevator for storage in silos. Thecementfrom silos is fed to the packer machines.
It is generally added in very small amounts (about 2% by weight) to the burnt cement (called Clinker) after it is taken out from the kiln and before it is sent for grinding. Gypsum is a sedimentary rock having a composition of calcium sulfate (Ca SO 4. 2 H 2 O). It is added for imparting a retarding effect in the setting of cement.

Portlandcementis two processes, known as ‘wet’ or ‘dry’ processes depending upon whether themixing and grindingof materials done in wet or dry conditions. A wet process was popular in the early years because of the possibility of more accurate control in themixingof raw materials.
Theconcrete grindingmachines mostly use some sort of abrasive such as diamond or silicon tools togrind. Diamond tools used forgrindingusually are usually diamondgrindingcup wheels. The machines come in a variety of sizes with quality of finishes determined by the grits in a machine.
Mixing and grinding of cementclinker with gypsum; Crushingand Grinding: In this phase, soft raw materials are first crushed into suitable size. This is done usually in cylindrical ball or tube mills containing the charge of steel balls.Mixingthe Material:
