Cement clinker - Wikipedia
Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.

The Pin Mixer: A Preferred Device for Pelletizing Gypsum & Limestone
Raw and pelletized limestone. With similar characteristics and identical end use markets, limestone and gypsum are frequently processed using the same pelletizing production line. Historically, this process has consisted of a disc pelletizer and rotary dryer with a screening and recycle circuit, such as that shown in the diagram below.
Portland cement - Michigan State University
The mining, production and uses of cement, clay and shale are quite similar. Cement is made from gypsum, shale or clay, and limestone. The term "cement" is most often used to refer to Portland cement. Portland cement, when mixed with sand, gravel, and water, makes concrete, which is an essential element of the construction industry.
Lime and Gypsum | Gericke
Singe shaft mixers are an economical solution for many mixing processes of limestone and gypsum-based products. Volumetric and gravimetric feeders often form part of such a mixing solution. Another typical application is plasterboards, where Gericke has installed many feeding systems in the production of such gypsum boards around the globe.
Gypsum - Wikipedia
Gypsum is a soft sulfate mineral composed of calcium sulfate dihydrate, with the chemical formula CaSO 4 ·2H 2 O. It is widely mined and is used as a fertilizer and as the main constituent in many forms of plaster, blackboard or sidewalk chalk, and drywall. Alabaster, a fine-grained white or lightly tinted variety of gypsum, has been used for sculpture by many cultures including Ancient Egypt ...
Lithium Production Processes - ScienceDirect
During the period from 1950 to 1984, Foote Mineral Company (now Chemetall, Germany) operated a plant using a lime-roast process to produce lithium hydroxide from spodumene. 2 In this process, spodumene was mixed with lime for calcination at 1030–1040 °C.
Lithium Production Processes - ScienceDirect
The gypsum–limestone process was later utilized by Büyükburç and Köksal 69 to extract lithium from a boron clay containing 0.2% Li. A mixture of the clay with these additives was sintered at 915 °C for 110 min and the calcine was then subjected to water leaching at room temperature, resulting in approximately 88% Li recovery.
How Cement Is Made
Concrete is formed when portland cement creates a paste with water that binds with sand and rock to harden. Cement is manufactured through a closely controlled chemical combination of calcium, silicon, aluminum, iron and other ingredients. Common materials used to manufacture cement include limestone, shells, and chalk or marl combined with ...

Gypsum Product - an overview | ScienceDirect Topics
Wet scrubbing with limestone and lime are the most popular commercial FGD systems. The inherent simplicity, the availability of an inexpensive sorbent (limestone), production of a usable by-product (gypsum), reliability, availability, and the high removal efficiencies obtained (which can be as high as 99%) are the main reasons for this popularity.

Wet flue gas desulfurization was simulated to improve gypsum production using low-grade limestone. High-grade limestone with 94 wt% CaCO 3 content is used for producing gypsum with 93 wt% purity, but owing to the resource depletion of high-grade limestone, low-grade limestone should be replaced as an alternative. However, low-grade limestone with CaCO 3 purity of less than 94% contains ...

Gypsum Product - an overview | ScienceDirect Topics
1 Production of Building Gypsum Major raw material of gypsum is natural dihydrate gypsum (CaSO 4 · 2H 2 O) and natural anhydrite (CaSO 4) (also named hard gypsum). Both are named as raw gypsum. Common building gypsum is hemi-hydrate ( ), decomposed from dihydrate and anhydrite when heated to 1500-1700 ºC.

Flue Gas Desulfurisation - an overview | ScienceDirect Topics
Flue gas desulfurization (FGD) is a very common method for gas claning adopted in a gas processing plant. In this process, the flue gas with acid vapors is scrubbed to remove it as a by-product. Most of the FGD processes use alkali to scrub the flue gas. Many designers of FGD adopt the limestone gypsum process.
