Milling and grinding

Milling and grinding of raw material, minerals and cement is a rough process, with highly abrasive and hard feed materials that can accelerate equipment wear and tear. This leads to increased costs for equipment and spare parts replacement, and costly maintenance. It is crucial that the equipment used for milling and grinding can withstand such harsh materials. Our range of milling and grinding technologies have been tried and tested around the globe. Our vertical roller mills, horizontal mills, hydraulic roller presses and stirred mills have for many years offered efficient milling and grinding, flexibility, cost savings and easier maintenance. Whatever the application, one of our robust milling and grinding solutions will be suitable for grinding all types of feed materials including hard rock ores, raw, cement or slag. We work closely with you to realise the potential of the technology that will benefit you. Some of the features you can benefit from in our milling and grinding solutions include: Long-lasting wear parts, hardfaced with the toughest material including TRIBOMAX® Compact layout Easy access for maintenance Low vibration Low noise level Ability to grind without water Segmented wear parts Fast drying Ability to handle large feed particle size material Easy switching for different cement types Flexibility in installation set up Optimum product fineness

With the knowledge and experience gained throughout the years, we ensure that you have the best milling or grinding solution possible, whether you are working in the cement industry or mining industry. For the cement industry, our Hydraulic Roller Press is suitable for water-scarce locations as it does not require water for deagglomeration of feed material in the roller press. It is also adaptable to three different types of grinding setups: pre-grinding, semi-finish grinding and finish grinding. The OKTM mill can skilfully grind raw or cement feed material and offers parts commonality, simplifying spare parts inventory and facilitating easy switching of parts between vertical roller mills. Our ATOX® coal mill has large rollers with great grinding capability of all types of coal, tolerating moisture levels up to 20 percent. For the mining industry, our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent. It is primarily used in the gold, copper and platinum industries as well as in the lead, zinc, silver, and nickel industries. Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media. Our ball mills are the most robust design in the industry, available with either geared or gearless drive arrangements. The cost-effective FT Series mills are smaller, gear driven and feature hydrodynamic lubrication.

Understanding the challenges you face when milling and grinding hard feed material, we have built our technologies to last. We have paid particular attention to the wear parts because they are right there where the action is, making it all happen. We hardface them with the toughest materials for increased longevity. It is also possible to manoeuvre the wear parts in our vertical roller mills to maximise their lifetime and encourage even wearing. There is no doubt that milling and grinding cement and other feed material is tough work. We offer well-designed technologies to endure virtually any hard rock ore or raw material, with differing moisture levels and particle size.
