  • Cutting Carbon through Industrial Energy Efficiency: The Case of Midwest Pulp and Paper Mills

    While manufacturing is a critical part of the U.S. economy, it’s struggled over the last several years—both financially and environmentally. Overall U.S. manufacturing employment has dropped by more than one-third since 2000. Meanwhile, U.S. industry—of which manufacturing is the largest component—still ...

  • Milling filter cakes - Cutting instead of pressing to achieve more uniform particle size

    There are various methods of separating solids from a suspension. These include filtration, centrifuging and drying. In most cases, further processing of the resulting products cannot be carried out directly. They have to be reduced to the right particle size by means of a mill. This can be done with a Gericke Nibbler, which shreds the filter cakes efficiently using a basket and screen assembly. ...

  • Efficient steam production in paper mills

    The paper and pulp industry is an energy and emission intensive industry. Steam is an essential part of the paper making process with steam boilers, steam distribution systems and other processes accounting for a large percentage of a paper mill’s energy costs. Useful energy is often lost from boilers and process equipment such as heat exchangers, dryers, evaporators etc, as well as from ...

  • A second generation of clear-cut success

    Massachusetts clearing and grubbing contractor builds on a 43-year legacy with great people and great equipment. Some of the most desirable land in the Northeast lies within the rolling, wooded New England countryside. Among the clearing and grubbing contractors performing the important first step of commercial and residential development in the area, one of the better known is Letourneau ...


  • Multiobjective optimisation for environment-related decision making in paper mill processes

    Considering only environmental impact or only profit is not enough to manage chemical processes. This study focuses on the optimal scheduling of cutting papers using the multiobjective optimisation programming. Two independent objective functions are introduced in this paper, the production cost and trim loss with the constraints of satisfying the customer orders. The Goal Constrained Programming ...

  • Cut-Off Wall - Abandoned Mine Tailings Pond - Case Study

    Problem At an abandoned mine in the Yukon Territory, mining for both Gold and Zinc took place until the mid 1950's, with the processing of the ore taking place on the banks of an adjacent lake. Processing methods resulted in the creation of a large mine tailings pond that had high concentrations of iron, arsenic, zinc and lead. Spring runoff and summer rainfall then infiltrated through ...

  • Analysis of the contact conditions between chip and tool using nanostructured coated cutting tools

    The stages of contact between a metal chip of AISI 1018 steel and a coated cutting tool creates significant opportunities for manufacturers of machined products to understand how dry machining and minimum quantity lubrication affects the economics of manufacturing. The present work not only compares various computational approaches to the solution of shear plane and tool face temperatures during ...

  • Intensified ribbon blending of melamine compounds cuts cycle times 25% for furniture molder

    Melsur Corporation, the world's leading supplier of hard plastic melamine school furniture, molds components from a mixture of resin, wood flour and pigments. Each of the 32 color variations, 30 products and custom designs must be blended individually, a process that can take up to four hours, depending on product. Anything less than empirically defined cycle times alters the final color and ...

  • A cut above - A sanitary rotary cutter-crusher solves a pharmaceutical product company`s size reduction problem

    "We make this pharmaceutical product that ends up being big bricks of tough, brittle material", says the blending team leader of a growing pharmaceutical products company, "and we couldn't reduce it to the size it needed to be. I can't even begin to tell you how frustrating it was." The team leader is discussing the problem his company had with one of its key products, a bulk sweetener ...

  • A new sustainability model for machining processes

    It is generally recognised that the sustainability concept integrates economic, environmental and social aspects. It would be interesting for manufacturers to be able to know which process, workpiece materials or machining condition is more sustainable than another. In this paper, a new model for the sustainability in the machining field is proposed with the goal to increase productivity, reduce ...

  • Mathematical analysis of the micromachining of 316L stainless steel

    The interactions between 316L stainless steel and a multi-point cutting tool create significant opportunities to understand how dry milling of hardened materials affects micromachining conditions. The present work not only compares various computational approaches to the solution of shear plane and tool face temperatures during semi-dry machining, but also discusses how the accompanying machining ...

  • An analysis of mechanical micromachining

    The analysis of the high-speed mechanical micro milling process is described in this paper. The present work not only compares various computational approaches to the solution of shear plane and tool face temperatures, but also explains why there is a difference when calculating temperatures generated during the micromachining process. The analysis shows that the computed temperature of the shear ...

  • Metallic mould inserts for fabrication of polymer microfluidic devices

    In this paper, three metallic mould inserts for fabrication of polymer microfluidic devices were produced using different methods. Firstly, metallic glass mould insert was cut by high speed micro-milling. Secondly, 316L stainless steel mould insert was made by micro metal injection moulding (μMIM) using D50 = 4 μm powder. Finally, 316L stainless steel powder with a smaller particle size of ...
