1. Introduction. Portland cement is currently one of the most used construction materials with the best compromise between the high demand and the associated low cost together with its high performance and flexibility [].It was estimated that global cement production rose up to ~4000 Mt·yr −1 in 2016 [].. The base material for cement is the clinker.

Cement Production - an overview | ScienceDirect Topics

Cement production is one of the largest industries in the world. Annual world production in 2013 was approximately 4 GT (of which, about half was in China). It is produced in kilns at around 1400o C (2500 o F), and approximately 750 kg (1650 lb) of CO 2 are released for each tonne (2205 lb.) that is made.

Mill (grinding) - Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

In many subsea well designs, the liner is partially cemented around the shoe, and a liner lap packer is used to seal the liner top. This is necessary when the fracture gradi-ent cannot withstand the equivalent circulating density re-sulting from the pressure drops associated with cementing the entire liner. Drilling liners may be installed to:
