the mill power and the efficiency of the mill operation (Van Nierop and Moys, 2001). If a SAG mill has been designed with a conventional power or specific energy model which do not con-sider the projected feed size distribution it is likely that this mill will reach the expected power consumption .

Optimization addresses the grinding process, maintenance and product quality. The objective is to achieve a more efficient operation and increase the production rate as well as improve the run factor. Consistent quality and maximum output with lower specific power consumption results in lower operating costs per unit of production.

Track Specific Energy Indices-TIP 0404-63 Steam consumption (kg or lb steam/ton of paper). Electricity consumption (kWh/ton). Natural gas consumption (m3 or kscf/ton). Total energy consumption (kJ or MMBtu/ton). Water consumption (m3 or gal/ton). Compressed air consumption (m3 or kscf/ton). Condensate return to power house (%).

Jul 13, 2012· The aim of this study is to benchmark the specific energy consumption (SEC) of similar processes within different paper mills in order to identify energy improvement potentials at process level. We have defined improvement potentials as measures that can be taken at mill/process level under assumed fixed inputs and outputs.

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().

Mar 13, 2018· The table shows the energy consumption of a specific combed yarn in a modern factory with its production steps. It can be seen from the table that 221.1kWh energy is used for a given spinning line of 1000 spindles, 61% of which is consumed by machines and the highest energy consumption with 30% share occurs at the spinning stage.

The Asset Based PI Example Kits are designed to help you learn how to apply asset- based PI to common, industry-specific business objectives. In this example kit, the specific power consumption, a measure of energy used to produce product, is calculated for several mills and several grades of product, allowing for comparisons and identification of lower-performing mills.

Grate Discharge Ball Mill: This type of mill usually works with a high circulating load and thus produces very little extreme fines. The specific power consumption is therefore less than for an Overflow Mill. A Grate Discharge Mill will also have 15—25 % higher capacity per volume unit as compared with an Overflow Mill.
