The final manufacturing stage at a cement plant is the grinding of cement clinker from the kiln, mixed with 45% gypsum and possible additives, into the final product, cement . In a modern cement plant the total consumption of electrical energy is about 100 kWh/t . The cement grinding process accounts for approx. 40% if this energy consumption.
Grinding can be done in batches, or in a continuous flow process (which is more common). First, material enters one end of a vibratory grinding mill drum into horizontal cylinders. Then, the mill uses a vibratory motion to mix and grind the particles, with operating speeds ranging from 800 to 1500 rpm. Typical vibratory mills use attrition and ...
Grindability of a 95/5 OPC at various Blaine fineness: o 2732 kWh/t at 3,000 cm²/g. o 3947 kWh/t at 4,000 cm²/g. o 5869 kWh/t at 5,000 cm²/g. Every 100 cm²/g increase in cement fineness increases the mill power consumption by 12 kWh/t for a closed circuit mill 23 kWh/t for an open circuit mill, a sheer waste if this is not required ...
A mill is a device, often a structure, machine or kitchen appliance, that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (, via a hand crank), working ...
The grind index is calculated performing a mass balance around the ball mill circuit to estimate the cyclone overflow density (viscosity effect) and a correction factor due to specific power consumption (size effect). The grind cut index is maintained by controlling the addition of water to the cyclone feed. This water control method sets the ...

The slag grinding plant in Nanchang is in operation since November 2005. The roller mill is a type RMS51/26 with an SEPOL RMS435 separator. For a feed material consisting of 95% slag, 4% gypsum and 1% limestone a capacity of 80t/h finish product with a fineness of 4400cm 2 /g according to Blaine was warranted.
Cement grinding plant is the last station in the cement production line. Its power consumption accounts for 65% 75% of the whole cement plant. Therefore, reducing the energy consumption in the cement grinding process is of great significance for energy conservation and emission reduction of the cement manufacturing plant.
This new grinding process is designed for finish grinding and also for pregrinding. The energy saving is similar as roll press, roughly 30% to 50% in respect to the ball mill, but with a moderate circulating load and grinding pressure. After a research phase on a 1 t/h pilot plant, a first 25 t/h industrial plant was achieved in cooperation ...
