Coal Mill Henan Unishine Mining Machinery Co Ltd. Coal vertical mills are designed to achieve the maximum rated capacity grinding a design coal with a grindability of 55 HGI and 8-12 percent moisture and achieving a discharge fineness of 70 per cent passing a 200 mesh screen 74 micron and 99.5 per cent passing a 50 mesh screen.

With near 0% remaining on the 50-mesh sieve, at least three points are needed on the Rosin-Rammler Chart to plot the fineness results. Four sieves of 50, 100, 140, and 200 mesh are recommended for fineness sampling. Fuel line fineness should be 75% or more passing a 200-mesh screen and a maximum of 0.1% remaining on the 50-mesh screen.

Improved 50 mesh by adjusting classifier blades. By conducting periodic Iso-kinetic coal sampling pulverizer performance can be tracked so that maintenance decisions are based on the truly important measurement. Issue: 200 mesh fineness had deteriorated over time which was monitored by testing. © STI, Storm Technologies, Inc.

static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while the SLS dynamic classifier produces coal fineness levels of 100% <100 mesh and 95% <200 mesh, or better. NEW MPS MILL DEVELOPMENT

As feed rate decreased, fineness improved. Note that better than ±10% fuel balance is not achieved until better than 70% passing 200 Mesh is achieved. When >10% fuel imbalance is observed, burner lines with higher fuel flows typically have less desirable fineness. Burner lines that have less fuel typically have better coal fineness.

11-11-2009· While all these are regarding the mill performance, the coal fineness and mill out let temperature also affect the boiler performance. The coal fineness has an effect on the combustion performance like the bottom ash percentage combustibles when the plus 50 mesh percentage goes up. It has been very well established that in the case of tangential firing

As feed rate decreased, fineness improved. Note that better than ±10% fuel balance is not achieved until better than 70% passing 200 Mesh is achieved. When >10% fuel imbalance is observed, burner lines with higher fuel flows typically have less desirable fineness. Burner lines that have less fuel typically have better coal fineness.

MILL THROUGHPUT. The amount of fuel in Tons/Hr that the pulverizes is capable of handling with maximum power (amps), acceptable mill outlet temperatures and airflow limits COAL FINENESS. It is necessary to obtain levels of 75% passing 200 mesh and near zero on 50 mesh to improve fuel balance and distribution

The SAS Adjustable High Spin Static Classifier Retrofit is a proven and reasonable alternative to making the substantial capital commitment required for Dynamic Classifiers. SAS customers have achieved 6% to 15% capacity improvements, while concurrently reaching 99.8% thru 50 mesh and 76.2% thru 200 mesh fineness levels – grinding at 42 HGI coal.

Much of the improvement can be traced to the need to achieve higher fineness levels. As we have mentioned before, our goal for optimum combustion is to attain a minimum of >75% passing 200 Mesh with <0.5% remaining on the 50 Mesh at pulverizer full load. Higher fineness at full load can cause extremely high fineness at lower coal flows.
