Since the installation of an OK™ Mill at India''s Orissa Cement Limited in Midnapore, the plant has consistently met or exceeded the performance guarantees regarding capacity, fineness and specific power consumption. The mill at Orissa Cement was guaranteed to produce 212 tonnes per hour of PSC at 3800 cm2/gm Blaine without the use of ...

A cement mill (or finish mill in North American usage) is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement is currently ground in ball mills and also vertical roller mills which are more effective than ball mills.

Feb 10, 2016· Specific power consumption high for ball mill and Low for VRM ; ... Overall ball miil is good option for Cement mill but only has limitations for higher capacity, as two ball mill to be installed for One VRM, but in case of breakdown one ball mill can be in operation.

After the upgradation of VRPM circuit at Maihar Cement Limited, Satna, cement grinding capacity increased from 170 TPH PPC to 226 TPH PPC at blaine of 3300 cm2/gm and savings were witnessed in specific power consumption of kwh/t.

ball mill specific power consumption. Jan 07, 2015 In other words, Tdp is the saturation temperature of water corresponding to the vapor pressure: Tdp = Tsat Pv 80 Cement Mill Specific Power Consumption: A cement mill is usually limited by drive power so that any reduction in kWh/t translates in to increased production capacity as well as a reduced unit power cost.

Key words: power draw, cement, dry grinding, ball mill electricity consumption for cement production is used for grinding the raw material .. In order to design a ball mill and to calculate the specific .

Grinding of cement to a lower Blaine value will reduce the specific power consumption . A comparison of typical specific energy consumption of Cemex ® mill with conventional multicompartment ball mill grinding and HPGR pregrinding closedcircuit operations is given in Table 1.

The basic parameters used in ball mill design (power calculations), rod mill or any tumbling mill sizing are; material to be ground, characteristics, Bond Work Index, bulk density, specific density, desired mill tonnage capacity DTPH, operating % solids or pulp density, feed size as F80 and maximum ''chunk size'', product size as P80 and maximum and finally the type of circuit open/closed ...

The consumption of energy by the cement grinding operation amounts to one third of the total electrical energy used for the production of cement. The optimization of this process would yield substantial benefits in terms of energy savings and capacity increase. Optimization of the Cement Ball Mill .

In this study, the first and second law analysis of a raw mill is performed and certain measures are implemented in an existing raw mill in a cement factory in order to reduce the amount of energy consumption in grinding process. The first and second law efficiencies of the raw mill are determined to be % and %, respectively.

Energy consumption assessment in a cement production plant is studied in this paper and a guideline for reducing energy consumption is provided according to a national standardISIRI 7873. Based on energy assessment, several energy saving actions were implemented and valuated.

Salah satu tahap proses penggilingan akhir di pabrik semen adalah cement mill. Saat ini tipe mill yang masih banyak digunakan untuk penggilingan semen adalah tube mill/horizontal mill walaupun ke depannya diprediksi akan lebih banyak yang beralih ke vertical roller mill karena beberapa kelebihannya seperti kapasitas lebih besar dan specific power consumption lebih rendah.

Lucky Cement Corp. in 1993 and commissioned in 1994, for grinding cement at its Pu Shin plant.
