Comminution entails reducing the particle size of the raw material by crushing, grinding, and milling or fine grinding. In mineral processing parlance, comminution in coarse range is known as “crushing” and in fine range it is called “grinding”. Comminution : The act or process of reduction of particle size with

Life-cycle assessment (LCA) is a method for assessing the environmental impact of products, processes and services. Usually, LCA is used to evaluate the total environmental burdens and benefits over the entire life cycle for a product from “cradle” o “grave” including material and energy used during extraction and processing of raw materials, manufacturing, transportation, reuse

The percentage of raw materials (compounds) accounted for by rubber recycled materials was 2.42% for the entire group. Regenerated rubber powder is a powdered material obtained from grinding waste tires, principally by using heat on the waste tires, and this recycled material contributes to major savings and recycling of resources.

The illustration displays the recycling process of bottles made of plastic. Overall, the plastic reusing process is cyclic and consists of five main stages: sorting at the center, compressing into blocks, crushing it, producing plastic pellets, heating it to get raw material that is then used to make plastic products and the cycle starts again.

Raw Material Extraction. The first step in the production of plastic objects is extracting the raw material that is derived from natural gas or refined crude oil. The drilling is done by heavy machinery to take out raw material from the underground. The collected raw material is sent through the pipes for the refinery process.

The study is aimed at maintaining maximum capacity of closed-cycle crushing units using the automated control system by an optimizing extremal control method. This method is based on an optimized parameter extremum search that stores maximum increment and stops the search in the vicinity of maximum capacity.

1) Calculate and share detailed raw material demand forecasts at regular intervals with service centers and mills . By sharing what we call a “material demand profile” with the sources of the raw material, OEMs can reduce risk for their raw material suppliers enabling them to operate more responsively, while increasing the OEMs ability to control pricing and ensure availability.

Raw material preparation From the quarry to preheater feeding with raw meal The cement manufacturing process starts with the extraction and preparation of the raw material. Even at this stage, the requirements are high because only with homogeneous and high-grade raw meal is it possible to manufacture high-grade cements in a cost-effective manner.
