Bowl Mill s Raymond® Bowl Mill. The Raymond® Bowl Mill is considered the finest vertical roller mill available for pulverizing coal. With the high cost of fuel, many companies are discovering that it is increasingly cost effective to utilize coal or petroleum coke as primary or alternative fuel for firing kilns, air heaters and other process equipment.
pressurized seal air is also used to prevent leakage of coal dust from the mill and to protect bearings in the grinding rollers. MILL SYSTEM COMPARISON AND PERFORMANCE Refer to Table I for a summary of the design features for each mill system. Mill Comparisons—General The BTM is a lowspeed mill that primarily grinds coal by impact and attrition.

For the mill equipped with spring load system, the grinding force is overloaded at reduced mill load. This will result in additional wear on roller and table segments and will produce excessive mill at high mill load operation, the grinding force is insufficient to meet the requirement for mill load increase. Figure 6.
loading system BW''s AutoSpring™ automatic wheel loading system allows for variable adjustment of the spring load exerted down against the roll wheel assemblies (Figure 5). When operating at low coal flows, spring pressure is automatically reduced to minimize mill vibration. At high coal .
This regulation, by sweeping pulverized fuel from the mill, is very fast; comparable with oil firing response, but needs the coal level to be maintained in the mill. A control circuit monitors the coal level in the mill, and controls the speed of the raw coal feeder to maintain it.
Hydraulic technology, with its high output power,excellant control precision, less space and other advantages, is widely used in electric power systems, including oil lubrication system and digital electrohydraulic control system of turbogenerators, oil discharge and Note nitrogen firefighting systems of large electri power transformer.

The advantage of this system is that it is not necessary to store the hazardous ground fuel: it is used as soon as it is made. For this reason it was the system of choice for older kilns. A disadvantage is that the fuel mill has to run all the time: if it breaks down, the kiln has to stop if no backup system is available.
