Jun 02, 2017· The equation for Rittinger's Law can be written as: E = K R f c (1/L 2 – 1/L 1) Where: E=Energy, K R =Rittinger's Constant, f c =crushing strength of the material, L 1 =initial length, and L 2 =reduced length. Kick's Law states that the energy is proportional to the size reduction ratio.
Introduction. Power generation industry studies have shown that coal pulverizers are an area where improved equipment reliability is badly needed. The Electric Research Institute (EPRI) has determined that 1% of plant availability is lost on average due to pulverizerrelated problems.1 EPRI also identified oil contamination and excessive leakage as two areas where pulverizer drive train ...
A pulverizer (coal pulverizer) is installed for this purpose, and pulverizes pieces of coal several centimeters in diameter down to fine particles. The pulverizer includes pulverization, drying and classification functions. The classification function plays the important role of ensuring that only fine particles are sent to the boiler.

Pulverizers (coal pulverizer) are used to pulverize pieces of coal into fine particles (100μm) before placing into a boiler, to ensure efficient combustion. Pulverizers have three functions, pulverization, drying and classification. The classification function plays the important role of ensuring that only fine particles of the pulverized coal ...
Coal pipe F9 on pulverizer B was the only pipe that met the original plant fuel specification guarantee of 70% passing 200 mesh, which is far short of the 75% minimum we use. Even so, fuel fineness and fuel distribution overall was poor, and it resulted in slagging, fouling, and higher-than-desirable fly ash LOI.
