Dr. Loesche opened a special two-day conference to celebrate Loesche's 100th anniversary. Loesche has experienced significant developments that have kept the company at the forefront of comminution technology since 1906. Key milestones included Dr. Loesche's grandfather inventing the vertical mill with a flat table in 1927, the successful sale of the first 4-roller mill in 1972, and the invention of the 2+2 and 3+3 technologies in 1993. Currently, Loesche has approximately 700 mills in operation worldwide and focuses on research and development to continuously improve vertical roller mill technology.
This document provides information about Loesche mills for grinding ores and minerals. It discusses Loesche's history of providing mills to the ore industry since 1961. It describes the technology and principles of Loesche mills, including compressive and shear grinding mechanisms. It also summarizes the advantages of Loesche mills for ore processing applications, such as lower energy consumption, steeper particle size distributions, and higher mineral liberation. Finally, it discusses customer benefits such as reliability, customized solutions, and aftersales support.
Selective Comminution of Concrete Waste and Recovery of the Concrete Constitu...LOESCHE
Using a Loesche VRM, trials were carried out in order to determine the extent to which the constituents of concrete waste could be made suitable by a special recycling process for use as a substitute for the natural rock fraction in components. In this process, the employment of suitable separation equipment played a crucial role.
Dolomite grinding in the Ukraine.
Summary: In summer 2009 a vertical roller mill, type LM 15.2, was successfully
commissioned for dolomite grinding in the Ukraine. This compact mill was set up at
Ternopolsky Karyer in Ternopol/Ukraine. It was ordered by OJSC Nadrabudinvest,
a Ukrainian company with a product range covering sugar, building materials and fertilizers.

Loesche Automation offers turnkey automation solutions and software development for all your automated process and production procedures. We plan with you, generate a concept and provide you with the necessary services.
Loesche mills have become firmly established in the grinding of industrial minerals such as limestone, bentonites and dolomite. The applications for ground limestones of various particle sizes are both broad and diverse.
Loesche Technology has been innovating in grinding mill technology since 1927. Key developments include the world's first spring-loaded air-swept mill, introduction of this technology to other industries like cement and ores, and development of highly efficient classifiers. Today Loesche provides vertical air-swept mills for raw materials, cement, slag, fuels, minerals and more. Their product line covers a wide range of throughput capacities.

Korea builds their first IGCC plant with proven Loesche technology. Loesche signed a contract to supply two LM 43.4 D coal mills for Korea's first 300 MW IGCC demonstration plant in Taean. The Loesche mills will grind, dry, and classify a coal and additive mixture to produce 95 tons/hour of raw material for the plant's gasification process.
Loesche is launching its new LM-Master for advanced vertical roller mill (VRM) control. This automation solution stabilises the VRM to allow operation with lower vibration. It also optimises mill performance by making accurate control actions several times per minute and offers continuous monitoring of the milling circuit for improved operational visibility.

Holcim is one of the world's leading suppliers of cement and aggregates, operating in over 70 countries worldwide. It established a presence in the Philippine cement industry in 1974 through its subsidiaries Alsons Cement Corporation and Union Cement Corporation. Holcim's strategy focuses on cement and aggregates production, geographic diversification, and balancing local and global leadership. It prioritizes innovation through research and development to offer sustainable and high-quality products.
The cement industry is worldwide one of the main contributors to man-made CO2 emissions, estimated at 7% of global emissions.
To keep pace with the demand and pressure to reduce CO2 emissions, a shift to sustainable building materials for housing and infrastructure must still be continued.
Cement manufacturers can make significant progress toward sustainability goals with alternative fuels and efficiency projects by reducing clinker content through cementitious additives (SCM).

The LOESCHE layout characterizes through a compact design and hence a small plan footprint - ideal from brownfield, but also for greenfield projects.
The BinEX discharge system has major components that include an inner cone, silo floor, discharge arm, and drive system. The inner cone and silo floor work together to form a natural angle of repose that prevents uncontrolled bulk material flow out of the central outlet. The discharge arm rotates to convey bulk material to the outlet at a rate determined by its speed. The silo floor design avoids buildups of material at corners. The BinEX comes in various sizes to accommodate different capacities and dimensions for discharging bulk materials like cement, coal, and minerals from silos. Loesche is an engineering company that designs, manufactures, and installs bulk material handling systems including silo discharge equipment.

An Integrated Approach to Alternative Fuel use in Cement MakingLOESCHE
The world is facing a growing challenge with handling the ever-increasing tonnages of waste materials being produced, while at the same time environmental pressures are driving the push to reduce fossil fuel use in industrial processes. Cement production is no exception in this respect.
Published in www.zkg.de
This document summarizes a case study from Morocco on converting waste into a reliable fuel for co-processing. A waste assessment was conducted to analyze the composition and potential of municipal solid waste. A technical assessment of cement kilns was also performed to evaluate their suitability for co-processing waste. Based on the results, a pre-treating process was designed to produce alternative fuels of varying quality that could be used in the cement production process. With proper quality control and legal framework, the project demonstrated that combustible waste can be reliably used as fuel to reduce greenhouse gas emissions.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
