Title: Impact hammer mill with narrowing inlet side - with first baffle plates and further baffle plates increasing angle of inclination
Inventor: POLUS EMIL DIPL ING
IPC: B02C13/282
Filed: 1974-04-04
Abstract: Impact hammer mill has a striker with pendular hammers and an inlet channel with chutes or baffle plates, with a parallel-axis outlet channel. The material enters the inlet channel with a carrier gas, is comminuted between the striker and the armoured housing walls, and is discharged by the gas. A chute projecting into the housing-side opening of the inlet channel is inclined, and deflects the stream of material against the running direction of the striker. The space of the inlet side, between the housing and striker, narrows polygonally or continuously in the direction of rotation of the striker, owing to baffler plates inclined toward the striker, and to differently-inclined baffle plates which cover the outlet opening's cross section when projected onto a plane perpendicular to the material flow. The latter plates oppose the direction of the striker and increase the angle of inclination in the direction of rotation. The kinetic energy of the hammers is effectively increased.
