  • The mills grind efficiently

    The – “Milser Mühle“ – has relied on AERZEN for 50 years When the Borgstedt Family took over the Milser Mühle 130 years ago, at first, it only produced feed material, and then, from 1918, it started to produce flour for human food. “Therefore we selected oilfree compressing AERZEN Positive Displacement Blowers of series GM as conveying air producer ...

  • Landfill grinding system

    A landfill needed a way to reduce their waste stream volume, increase the life of their landfill, and recover a recyclable, marketable product. Wood and yard waste material comprise up to 20% of their entire waste stream volume. Processing and recycling this material will extend the life of the landfill by 20 years. They chose WSM's Model 4864BH Horizontal Hogging System with a customized feed ...

  • Case study: Mechano-chemical grinding

    Challenge Traditional grinding mills reclaim only a fraction of precious metals from ore, leaving valuable material in the tailings. These minerals are more difficult to liberate, as it requires the ore to be ground to a very fine mesh. Approach GK was approached by a company who had a proprietary chemistry solution for recovering minerals from an existing ...

  • Ultrasonic pre-treatment of biosolid

    Low-frequency and high-intensity ultrasonic treatment of biosolid is a good method for biosolid disintegration. So, as a pre-treatment method of anaerobic digestion, it may replace the hydrolysis. Thus, we studied the effect of ultrasonic disintegration of biosolid at different ultrasonic power densities. Results showed that the Soluble Chemical Oxygen Demand (SCOD), Total Nitrogen (TN), Total ...

  • The Wheels of Integrated Product Policy Grind Slow

    Integrated product policy had an innovative feel when it appeared on the EU's environmental agenda in the late 1990s. But after much in-fighting and business lobbying, the White Paper on IPP issued by the European Commission in June proved disappointingly thin, and unlikely to make any significant impact on the market until the end of the decade at best. 'Fundamental changes in the way societies ...

  • High Output of Quality Flavors Demands Efficient Grinding

    EAST HANOVER, NJ Vanilla beans from Madagascar, cinnamon bark from Sri Lanka, ginger roots from Nigeria and many other natural flavors you enjoy have likely come from Givaudan Flavors Corp. which extracts flavor from natural products, concentrates it, packages and markets it to food and beverage manufacturers. Givaudan processes natural ingredients on a mass scale, placing high demands on its ...

  • Recovering oil from grinding sludge - Case Study

    Zahnradfertigung Ott uses RUF briquetting unit A large volume of sludge is produced in the grinding of high-precision gears. In most cases, this grinding sludge is disposed of at high costs. Zahnradfertigung Ott, a specialist manufacturer of gears, found a better solution: since 2005, the company is using a briquetting unit from RUF to recover 500 litres of grinding oil per day from the ...

  • Wastewater pre-treatment in a confectionery industry

    Description of the plant In a first step, wastewater accruing from the production of marzipane is cleaned by a screen. As flow and load to the plant are highly variable depending on the production process an aerated mixing and balancing reactor has been installed to equalise flow and load before final chemical pre-treatment. After adding of chemicals for precipitation and flocculation ...

  • Importance of the Pre-charge of Pressure Tanks.

    A pressure tank consists of an air and water chamber that are divided by a membrane. The air in the air chamber is compressed dry air. This so called pre-charge is a very important factor in the operation of a system with a pressure tank. It acts like a spring and stores the energy in a tank that is used to supply pressurized water when the pump is not running. The membrane that separates the air ...

  • Pre-event water contributions to runoff events of different magnitude in pre-alpine headwaters

    Precipitation and catchment characteristics of mountainous headwaters can vary largely within short distances. It remains unclear how these two factors determine the contribution of event water and pre-event water to stormflow. We investigated this in five neighboring headwaters with high annual precipitation amounts (>2,000 mm y−1) in a steep pre-alpine region in Switzerland. Rainfall and ...
