Calcined clay capacity then becomes similar to that of clinker production. Case study 2 – converting a wet-pro-cess kiln A mothballed long wet-process kiln was assessed for its potential for clay calcination production. The clay had a 10 per cent LOI, 10 per cent moisture, kaolinite, low-Fe and fine clay. In this case, having a fine feedstock and

 — Lemma et al. study of mixed-layer clay consisting mainly of illite (45%) and chlorite (14%) containing also non-clay minerals, such as quartz (30%) and feldspar (10%), revealed high optimal calcination temperature of the material. The highest value of strength activity index (SAI) of this clay was observed after calcination at 1100 °C.

The first part of this presentation refers to tests carried out on calcined clay granules at a pilot plant of Gebr. Pfeiffer using a vertical roller mill (VRM). In addition to the findings obtained for the grinding process (specific power consumption, wear rate of grinding parts), the results related to the material (fineness, physical ...

 — Clay calcination at lab scale: assessment of reactivity. Raw clay sample was dried at 110 °C for 24 h and ground to reduce particle size until Dv 50 = 5.5 μm in order to guarantee the homogenous diffusion of the heat in clay grain during calcination process. Thermal treatment of clay was carried out in a laboratory oven Naberthern LH30/14 ...

 — The first of these is a 0.3Mt/yr calcined clay and a 2400t/day cement grinding production line that was commissioned in mid-2020. This plant is based at Abidjan in Ivory Coast. The second is a new plant that Germany-based ThyssenKrupp Industrial Solutions is building for Oyak Çimento at Kribi in Cameroon.

C/Clay technology consists of calcination and a grinding stage. Both are coupled in a state-of-the-art process. C/Clay can be used to process all types of clays, regardless of moisture content, organic components, and grain size.. Particular attention was paid to the efficient use of energy and heat transfer with as little loss as possible.

the original clay, and (b) the phases in which iron occurs in clay its susceptibility to oxidation and reduction reactions. [21]. Color control during clay calcination The dehydroxylation of the clay (removal of the OH‐) takes place at temperatures between 350‐650°C, thus leading to

To avoid reddish color during calcination, iron oxides are reduced to the magnetite form by a reducing atmosphere maintained down to the stability temperature of the magnetite. Unlike conventional methods, our principle consists in dissociating the reduction phase from the calcination by performing it only during cooling, thus allowing:
