When it comes to grinding mill ring gear lubrication, there is a tidal wave of technical detail around the different lubricants, lubrication system designs, application rates and control strategies for how each lubricant is applied. This article breaks down the confusion to a few key points to ensure optimal gear lubrication.

Pooja’s background combines a bachelor’s degree in chemical and process engineering with a master’s degree in industrial environmental engineering, shaping her strong interest in sustainability and safety. When she first came across Metso, those themes immediately stood out. “I saw that Metso had a strong focus on environmental strategy and safety. It felt like a place where I could both learn and contribute,” she says.

First published on North American Mining. Metso and Loesche bring complementary strengths that, together, remove the traditional barriers and accelerate adoption of Vertical Roller Mill (VRM) technology in mining. VRMs fundamentally change how grinding and classification are combined, which opens a different performance potential compared to traditional concepts.

A large manganese ore processing plant with an annual capacity of 1.5 million tons employs a three-stage crushing circuit with closed-loop screening, using Metso crushers throughout the process. During production, screen blinding was particularly severe, reaching approximately 50%. The problem worsened during the rainy season when material adhesion became more pronounced, resulting in screening efficiency of only 60%-70% and high circulating loads.

What does Pride mean to you? Daiara: It’s about authenticity, respect, and the freedom to be who you are without fear. Pride represents the importance of creating spaces where people don’t feel the need to hide parts of themselves to belong. In my journey, especially working in a highly technical and traditionally male-dominated environment, I’ve learned how powerful it is when people feel respected as individuals.

From shutting down once every hour to clean blinded screen apertures to achieving 0% screen blinding rate and reducing screened product size by 5mm, Shangri-La Shenchuan Mining Company has realized both production increases and cost reductions. The secret lies in their adoption of Metso Trellex® LS screen media.

A comprehensive offering designed for Asia Pacific operations Mining businesses across Australia, Southeast Asia, and the Pacific operate in environments defined by high material volumes, geographically remote assets, and demanding shutdown schedules.

Across many of the world’s most intense port areas, customers often experience gaps in local support, engineering availability and responsive service for their bulk material flow systems and equipment. To address these challenges, Metso is strengthening its bulk material handling and port solutions offering through a significant and long-term expansion of its local presence close to customer operations.

First published on International Mining, April 2026. Across global mineral processing operations, recovery remains one of the most persistent and costly challenges. As orebodies become more complex and head grades decline, mines are increasingly dealing with finer mineral dissemination and more difficult liberation characteristics. In many cases, valuable minerals are not fully liberated at conventional grind sizes, leading to losses in tailings.

In mining operations, crushing and screening are often discussed as individual machines, along with the spare and wear parts needed to keep them running. This perspective is understandable from an operational or maintenance standpoint. However, it overlooks how closely these stages are connected. Crushing and screening do not operate independently. Perhaps the key issue is not only recognizing this connection, but working accordingly and also managing it as conditions change.
