High pressure roller press can be introduced as a pre-grinding step for the ball mill, in order to decrease specific power consumption in finish grinding and/or to increase the output of finish mill. Grinding capacity of finish mill increases by about 30%. Up to capacity increases are reported in India with the use of this approach.

The primary grinding is done by the Roller press and finish grinding takes place in Ball mill. Because of this, we can increase the Ball mill capacity as well as the Cement production. Also the feed materials which are coming from roller press to the ball mill are powdery form instead of Clinker material.

1.5.2. High-Pressure Grinding Roll. In high-pressure grinding roll (HPGR), the material is reduced by a highly compressive stress created by two counter-rotating rolls (one fixed and another floating) . This creates a critical fracture process that presses the material into a compact flow area. This flow area is shown in Figure 6.

The Industrial Revolution was the transition to new manufacturing processes in Europe and the US, in the period from about 1760 to sometime between 1820 and 1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power, the development of machine tools and the rise of the …

Slag vertical mill is a negative pressure air sweeping type grinding equipment, which will dry the slag and grind the slag. The slag ground by the grinding roller on the grinding disc is composed of two parts: a small part of new slag with high water content and most of the ground non-finished slag with lower water content.

The process involves cooling of the slag through high-pressure water jets, this leads to formation of granular particles. The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill or roller press to a very fine powder,which is called GGBS.

Energy consumption of a single-set high-pressure roller mill with 200 t/h capacity is reported to be less than 30 kWh/t-cement (NDRC, 2008. p. 48). In China, a 5000t/d cement grinding plant reduced electricity consumption by more than 30% (approximately 8~ 10kWh/t cement) by using high-pressure roller mills, instead of ball mills (NDRC, 2008. p ...

Incorporation of roller presses in the grinding circuits of cement manufacturing plants was borne out of the dire need to reduce the power consumed by ball mills in its finish grinding process. This study evaluated the wear phenomena of a roller press installed in a cement plant. Two improvised wear measuring devices (IWMDs) were constructed on a laboratory scale with chevron lines created …

High efficiency classifiers have been shown to bring about a reduction of 2.8–3.7 kW h/t in raw materials, save fuel and yield a narrow particle size distribution, increase the grinding mill capacity by up to 15%, produce more uniform particles of raw meal and cement and thus enhance the quality of the product and the clinker .
