For a ball mill grinding OPC to a fineness of 3200 to 3600 cm2/g (Blaine) the cost of wear parts (ball, liners and mill internals) is typically 0.15-0.20 EUR per ton of cement. For an OK mill grinding a similar product, the cost of wear parts depends on the maintenance procedures, i.e. whether hardfacing is applied.Increase productivity of vertical roller mill using seven QC tools Praveen Pareek1 and Dr. Vijayendra Singh Sankhla1 1 Department of Mechanical Engineering, GITS, Udaipur, India.

Roller mill is the main equipment in the grinding process, and the roller is the vital part of the mill which directly affects the grinding effect. During the grinding process, the materialTherefore, the wearing parts have long service life; the metal powder resulted from metal wear is small, so vertical roller mills can also grind the white cement raw material [15], [16]. • Installation of vertical roller mill system requires less space than a closed system Ball mill circuit.Review on vertical roller mill in cement industry & its

The grinding parts of the roller mill, consisting of roller shells and of a segmental grinding ring, show a wear rate appropriate to the properties of the raw material. the first large-scale vertical roller mill of the type MPS 3750 C for the grinding of Portland cement and slag cement was commissioned in a German cement plant. The results1.1. Vertical roller mills. The VRM is a commonly known grinding unit in the cement industry. The VRM sizes range from approx. 2 to 6 m in table diameter, and depending on the VRM size, the feed material will vary between pebble sized rocks in small VRMs and Ø150 mm fragments in large VRMs.The final product will typically be Wear mechanism of abrasion resistant wear parts in raw

From the working principle known the vertical roller mill: One, the grinding roller and the grinding disc must remain on the material layer grinding enough pressure, so that the material is rolled and crushing. The grinding pressure is roller pressure, it and the material grindability, moisture, wind speed, grinding and production requirementsQuartz is a hard mineral frequently being part in cement raw mixes. Hence it is of interest to correlate its content in the mixture with the wear rates experienced in vertical roller mills (VRM). From the experience of numerous laboratory VRM tests, it is known that the measured wear rates might not correlate with wear rates in full scale VRMs.Influence of quartz particles on wear in vertical roller mills.

The chemical compositions of such abrasion resistant wear parts are given in Table 1. These high chromium alloys are used in closed circuit dry grinding vertical roller mills (VRM) as wear liner on both table and rollers (Fig. 1). The heat treatment (hardening and tempering) results in a macro hardness of approx. 750 HV [2].
