Minimization of that cost is critical if oils derived by beneficiation and hydroretortingVertimill® Fruitful Outotec,Lower capital cost. Vertimill® requires a simple and small foundation, which means less floor space is required. In fact, in the same application a Vertimill® has 50% less footprint than a ball mill. Lower operating cost. Vertimill® is an energy efficient grinding machine.

  • Abstract USGS

    Working capital, based on 2 months of operating costs, was included in the capital cost of each mine and mill model. Working capital covers the cost of meeting operating costs in the initial stages of production, before revenue is generated from the first shipments of FEED MANUFACTURING COSTS AND CAPITAL ,Feed Manufacturing Costs and Capital Requirements. By Carl J. Vosloh, Jr., Economic Research Service, U.S. Department of Agriculture.
