Being an energy intensive industry, typically this segment of industry accounts for 50–60% of the total production costs [17].Thermal energy accounts for about 20–25% of the cement production cost [18].The typical electrical energy consumption of a modern cement plant is about 110–120 kWh per tonne of cement [19].The main thermal The vertical mill produced by our company is air-swept type, widely used in the grinding of raw cement, slag, cement clinker, raw coal and other raw materials. It gathers grinding, drying and powder selecting as a whole, with high grinding efficiency and high drying capacity ( the maximum material moisture can be up to 20% ).Vertical Mill Buy Vertical Roller Mill,Vertical Mill,Cement

According to their study, the energy and exergy efficiencies are determined to be 84.3% and 25.2%, respectively. Atmaca and Kano glu [17] also studied the raw mill in cement industry. TheyModern cement plants trend for the usage of vertical mill in cement grinding because of its many advantages of lower energy requirements, higher feed rates, simple layout (drying, grinding, material conveying and separation processes into just one unit), substantially reducing civil construction costs, lower noise level and improving theEffects of alternative calcium sulphate-bearing materials on cement

Coal mill is the main equipment in the pulverized coal preparation process.Because calcining top-grade cement clinker requires a stable supply of coal powder as the fuel of cement kiln, and more than 85% of pulverized coal should be finer than 200 mesh, water content less than 2%, and calorific value more than 6000Kcal/kg, therefore the pulverized coal e.g. Ball Mill, Vertical Roller Mill etc. Impact: High grinding media consumption will increase operating and consumable cost and reduces mill availability. Causes of underperformance: Inadequate choice of grinding media type Hard grindability of the material or additives Material filling level in mill too low.
