1. Introduction. The vertical roller mill (VRM) is heavy mechanical equipment that used in the cement materials industry to process cement, slag, and coal cinder (Pani Mohanta, Citation 2015).The equipment always needs to work in the environment of heavy load, high temperature, high pressure, high corrosiveness, electromagnetic radiation interference, and multifield coupling, thus it is ...

It is well known that most particle technology studies attempting to predict secondary properties based on primary properties such as size and shape begin with particle characterization, which means the process of determining the primary properties of particles in a wide spectrum from macro to nanoscale. It is a fact that the actual shape of engineering particles used in many industrial ...

Vertical stirred mills have been widely applied in the minerals industry, due to its greater efficiency in comparison with conventional tumbling mills. In this context, the agitator liner wear plays an important role in maintenance planning and operational costs. In this paper, we use the discrete element method (DEM) wear simulation to evaluate the screw liner wear.

This work concentrates on the energy consumption and grinding energy efficiency of a laboratory vertical roller mill (VRM) under various operating parameters. For design of experiments (DOE), the response surface method (RSM) was employed with the VRM experiments to systematically investigate the influence of operating parameters on the energy consumption and grinding energy efficiency.

Milling cutters are an essential component of a milling machine. As the name suggests, it is the cutting tool responsible for scraping the material outside the workpiece. All milling machines have a cutter. During a typical milling operation, the Cutter moves perpendicular to its axis, allowing it to remove material from the workpiece at the perimeter of the Cutter.

The vertical windmill, with sails on a horizontal axis, derives directly from the Roman water mill with its rightangle drive to the stones through a single pair of gears. The earliest form of vertical mill is known as the post mill. It has a boxlike body containing the gearing, millstones, and machinery and carrying the sails.

The first practical windmills were panemone windmills, using sails that rotated in a horizontal plane, around a vertical axis. Made of six to 12 sails covered in reed matting or cloth material, these windmills were used to grind grain or draw up water. [9] These windmills are recorded by Persian geographer Estakhri in the 9th century as being operated in Khorasan (Eastern and Western ...

Max Weber (), a founder of sociology, wrote long ago that a major goal of sociology was to reveal and explain "inconvenient facts" (Gerth Mills, 1946, p. 147). These facts include the profound influence of society on the individual and also, as we shall see throughout this book, the existence and extent of social inequality.
