Coal, lignite or petcoke are ground in the Pfeiffer vertical mill by using hot gases from a hot gas generator. The grinding plant can be inerted. The raw coal is dried while being ground in the mill even if feed moisture exceeds 25%. The feed size that can be handled is up to 100 mm, making two-step pre-crushing unnecessary.

Petroleum coke (petcoke) has been burned at kraft pulp mills to partially substitute for natural gas and fuel oil used in lime kilns. Due to the high vanadium and sulfur contents in petcoke, there had been concerns over the impact of burning petcoke on kiln and chemical recovery operations.

» Safe grinding using available hot gases from the process or from a hot gas generator » Stable and smooth mill operation even when grinding sphere-shaped petcoke » Highly efficient grinding, drying, and separating in one unit » Grinding-drying of raw coals with moistures exceeding 35% » Grinding can be performed in an inert atmosphere

Addition of Grinding Balls Watch raw mill SEC daily and add grinding balls in right timing →10% energy saving expected Ball diameter shrinks as time passes due to erosive effect. This leads to gradual increase of raw mill SEC. Filling level of grinding balls is also important in grinding efficiency. Optimum level of filling should be maintained.

As my previous article of Grinding Machine, I told, grinding is an important operation in manufacturing industry to get a final product, so for that, we need to know about the grinding wheel and its properties so that we easily choose a right wheel for the right material.. I assumed that you already have a brief idea about Grinding Machine. Don't worry! if you not learned yet …

equipment is used, air-swept mills are optimally suited for grinding solid fuels, such as coal or petcoke. Single-compartment mills are of a similar design to air-swept mills, but the material is discharged mechanically by a discharge diaphragm. These mills …

Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels.

One of the raw materials, calcined petcoke (CPC), is sourced from different parts of the world with different properties. As the ground product must have constant properties, the grinding process must be adjusted accordingly. Adding of crushed butts into the grinding mill is a process step which may become more important in future.

petcoke as fuel for cement production challenges in petcoke burning: difficult to grind low hgi, hence difficult to grind requires finer grinding due low volatiles: 1.5% on 90 micron (instead of conventional 15% on 90 micron) possible solution: to reduce residue: increase air separator rpm in vrm (.)
