mills have been used successfully for the combined drying and grinding of cement raw material, coal, cement clinker, blast- furnace slag and composite cements for many years.

The VRM technology was introduced in the mid-'90s for grinding clinker and slag by LOESCHE (Schaefer, 2001). Fig. 1 illustrates the grinding parts of a Loesche vertical roller mill. The grinding material is comminuted in the Loesche roller grinding mill between the rotating horizontal grinding track and stationary grinding rollers.

In this study, all the samples were obtained from the clinker grinding line 2 of the Ilam cement plant in the Iranian province of Ilam-karezan. Used a VRM (Loesche mill) with 160 t/h to grind the clinker, fed into the mill during the grinding process (%90 passing 32 mm). Fig. 3 shows the grinding circuit for VRMs. The Loesche VRMs at the Ilam ...

The energy consumption in the cement mills varies between 16.5 to 63.5 kWh/ton with an average of 36kWh/ton [1]. There are numerous factors affecting the energy consumption during clinker grinding. Clinker hardness imparts a wide variation to grindability. The hardest clinker takes about 80% more power than the softest one [2]. …

Customised. Technology. Widely recognized for its resilient designs, CPG comes with different designs for both wet as well as dry grinding. CPG can offer two types of bearing design of Ball mill: Highlights. White Metal Bearing. Best known for easy operational benefits. Designs of ball mills for all sizes of applications.

The effect of clinker grinding aids (GAs) on mill performance and cement properties is currently quantified in real-scale grinding plants. In fact, laboratory-grinding mills operated for given time interval do not consider the effect of circulating load, thereby leading to increased specific energy consumption (Ec) with excessively wide cement …

Cement Clinker Powder Production Process. The first stage: the crushing of raw materials. The cement clinker material is crushed by the crusher to the fineness (15mm-50mm) that can enter the mill. The second stage: milling. The crushed small pieces of cement clinker are sent to the storage hopper by the elevator, and then sent to the …
