竪型粉砕機の運転方法

Document Type and Number:

Japanese Patent JP4984688

Kind Code:

B2

Abstract:

To provide a method in which an unburned combustible content of an oil coke does not remain in a calcined material taken out from a rotary kiln even if the oil coke is used as a fuel when a lime sludge is calcined by the rotary kiln in order to produce CaCO3used as a filler in paper making.

The oil coke is crushed so that the particle diameter is DP100≤130μm and is supplied as the fuel to the rotary kiln, while the rotary speed of the upper-side peripheral part of a rotary table of an upright crusher is in the range of 2.7-1.8(m/s). Therefore, the unburned combustible content can be controlled and also a stable operation of the upright crusher 1 is possible.
