Sedimentary Rock Classification Diagrams. ThoughtCo/Andrew Alden. This diagram is used to classify sedimentary rocks according to the mixture of grain sizes in them. Only three grades are used: Sand is between 1/16 millimeter and 2 mm. Mud is anything smaller than sand and includes the silt and clay size grades of the Wentworth scale.
traditional ceramics - traditional ceramics - Vitrification: The ultimate purpose of firing is to achieve some measure of bonding of the particles (for strength) and consolidation or reduction in porosity (e.g., for impermeability to fluids). In silicate-based ceramics, bonding and consolidation are accomplished by partial vitrification. Vitrification is the formation of glass, accomplished in ...

The clay from the ground is removed by a mechanical digger. The second example is far more appropriate for the IELTS Process Diagram question and far more sophisticated in choice of language. Most of the description in your IELTS process diagram will use the passive voice but some verbs cannot be passive so are written as active.
The diagrams illustrate the way in which cement is made and how it is then used in the process of making concrete. Overall, limestone and clay pass through four stages before being bagged ready for use as cement which then accounts for 15% of the four materials used to produce concrete.
Clay Minerals There are three main groups of clay minerals: Kaolinite - also includes dickite and nacrite; formed by the decomposition of orthoclase feldspar (e.g. in granite); kaolin is the principal constituent in china clay. Illite - also includes glauconite (a green clay sand) and are the commonest

This process is called blending of clay. Tempering In this stage, water is added to clay and pressed or mixed. The pressing will be done by cattle or with feet of men for small scale projects, pug mill is used as grinder for large scale projects. So, the clay obtains the plastic nature and now it is suitable for molding.
These are ceramic products that are produced from unrefined clay, and combinations of refined clay and powdered or granulated non-plastic minerals. This includes pottery, stoneware, chinaware, porcelain, etc. To create these end products, the ceramic matter needs to go through the traditional manufacturing process, which goes as follows:
Place the clay between two pieces of canvas. Covering the clay with canvas will protect the clay while it is being rolled out. The pieces of canvas will prevent the clay from sticking to the table or getting marked by the surface or roller. Make sure the canvas covers the entire piece of clay and that there is some extra canvas in front of the clay.

MODERN CLAY BRICK PRODUCTION In the last 60 years a variety of factors resulted in radical changes in the European brick industry. Nowadays the modern clay brick production process in western countries is an optimal mechanized and automatic process, fully controlled to get the best quality products out of the process.
To begin, the clay used to make the bricks is dug up from the ground by a large digger.This clay is then placed onto a metal grid, which is used to break up the clay into smaller pieces. A roller assists in this process. Following this, sand and water are added to the clay, and this mixture is turned into two differing types of brick by either placing it into a mould or using a wire cutter.
