Loesche Mills for Cement and Granulated Blast Furnace
Grinding of cement clinker and granulated blast furnace slag in roller grinding mills (vertical airswept grinding mills) is a technology introduced by Loesche. The first use of Loesche mill, with a grinding track diameter of only 1.1 metres, was used as vertical roller grinding mills for grinding: • Coal • Cement raw material • Clinker / granulated slag • Industrial minerals, and • Ores The core elements of these PROCESS OPTIMISATION FOR LOESCHE GRINDING

Cement & Blast Furnace Slag Loesche
Grinding of cement clinker in vertical roller mills is a technology introduced by LOESCHE which was first used in 1935. Almost 30 years ago LOESCHE introduced the first vertical roller mill to grind both, cement clinker and granulated blast furnace slag, in one process. The concept of M- and S-rollers was established in 1992, In some developed countries such as Germany, the US, and Japan, converter slag has been used as a silicon fertilizer, phosphatic fertilizer, and microelement fertilizer.

A study of intergrinding and separate grinding of blast furnace slag
Abstract. Grinding-related parameters of blast furnace slag cements (BFC), such as Bond grindability, specific rate of breakage and breakage distributions were determined employing separate and intergrinding modes. Strength tests were performed on mortar specimens made by BFC prepared by these modes of grinding to the same fineness.the grinding bed in the mill. However, it also presents the risk of pre-hydration. This is where the use of vertical mills for slag grinding offers a further benefit as the mill not only grinds the material but also dries it in the process. The normally-moist slag, with an eight per cent water content, is dried and ground in one step while theSEPARATE OR INTERGRINDING? Loesche

The improve-ment of the grinding efficiency of dry slag by Grinding Aids is less pronounced as with clinker. Therefore, more interest is The aim of this study is to evaluate the effect that the size of grinding media exerts on ferronickel slag milling efficiency and energy savings. A series of tests were performed in a laboratory ball mill using (i) three loads of single size media, i.e., 40, 25.4, and 12.7 mm and (ii) a mixed load of balls with varying sizes. In order to simulate the Effect of Grinding Media Size on Ferronickel Slag Ball Milling

Australia: Germany-based Christian Pfeiffer has received an order for a grinding circuit comprising a 16.3m-long ball mill and a QDK T 250-Z type separator from Hallett Construction Materials. The circuit will have a capacity of 84t/hr, according to the supplier. Hallett Construction Materials plans to use the equipment at its upcoming Port be pulverized with laboratory mills. On the contrary, metallic objects such as steel nails or iron screws can damage the grinding tools which can lead to a considerable deterioration of the mill's performance. Therefore, it is necessary to sepa-rate the metal components before grinding (e.g. with mag-netic forces).The Art of Milling RETSCH
