Pressure breaker for preparing crushed material mixed with binder - has tube with striker working in conjunction with pressure grid and pressure wall facing rotor

摘要

For the pressure wall (18) a scraper device (11) is provided which stretches over the pressure surface (19) with crosswise-located scraper components (20). These scraper components are arranged between endless drive chains (21) around the two sides of the pressure wall (18). The drive chains are arranged around a guide shaft (12) arranged above the pressure plate and fitted with chain wheels and also around a similar but drive shaft (13), also with chains wheels, beneath the pressure plate (18). The drive chains (12) and the scraper components (20) on them are guided on guide rails (14) between the pressure surface (19) and parallel to it. USE/ADVANTAGE - For mixing crushed material with binding material, the build-up of the latter at the pressure wall being prevented, ensuring long operating times of undisturbed operation of the machine at constant power.
