An improved method for Estimating Grinding Media Consumption Rates. In 2007 Benavente established an empirical correlation for estimating grinding media consumption, based on operational parameters as well as Bond's Abrasion Index.
Grinding energy efficiency depends on the appropriate selection of cutting conditions, grinding wheel, and workpiece material. Additionally, the estimation of specific energy consumption is a good indicator to control the consumed energy during the grinding process. Consequently, this study develops a model of material-removal rate to estimate specific …
The larger energy consumption in those investigations might be largely explained by low feeding rates and low grinding efficiency that is defined as the ratio of net SEC to total SEC. Fig. 3 Actual, corrected, and net specific energy consumptions (SEC) for FHRs compared to those for scots pine obtained under constant power [ 15 ]
A few years ago, McGill University in Canada developed a new and more accurate test methodology for predicting steel media consumption. This test (Steel Media Wear Test) is licensed and currently being offered commercially by JKTech. The test also has the advantage that it produces estimates of the
Power consumption of Mixer grinders A typical Mixer grinder consumes 0.75 kWh of energy per hour of usage. That means an hour of usage can cost you 0.075 cents. A Mixer grinder is made up of universal motor with multiple tapped stator winding for speed control. This motor spins the blade is present inside the food container.
Based on the model originally developed by Benavente, a projection of grinding media consumption typically results in an error of approximately ± 12%, which until recently, was considered a satisfactory result given the lack of alternate methods to better predict consumption.
According to Outotec, its Vertimill provides the lowest total cost of ownership compared to other grinding mills in many applications due to its high energy efficiency, lower media consumption, low installation cost and minimal liner wear and maintenance. The mills can handle feed sizes up to 6mm and grind to products less than 20 microns.

This article aimed to review and discuss the available literature on the wear of grinding media. The consumption of the grinding media represents an expressive part of the grinding operational costs, reaching up to 50% of it. During grinding, a combination of abrasion, corrosion and impact results in wear of grinding media.
consumption rate, high energy efficiency and low unit cost have not converged. This has limited the application of such energy efficient grinding technology such as the IsaMill, and restricted its application to regrind and ultra fine milling only. 1.2 Keramax MT1 get price
Energy consumption varied with grinding methods, moisture content, speed, feed rate, and sieve size. Balasubramanian et al. (2013) reported that specific energy consumptions showed a reducing trend (310.71–30.55 kJ/kg) with increasing feed rate but the increasing trend with moisture content and sieve size openings.
