Title: Plant to clean lignocellulose or wood cellulose scraps for chipboard - removes foreign matter by hot gas flow into cyclone
Inventor: KRICHEL HERBERT
IPC: B07B11/02
Filed: 1977-05-17
Abstract: Foreign matter such as sand, stones, dirt, etc. is removed in a cleaning process from damp or wet particles contg. ligno-cellulose or cellulose, esp. wood scraps, cuttings, etc. for conversion to chips. The bond between the particles and the contaminating matter is reduced considerably by drying it first of all. The particles are then put through a separator for the removal of the impurities. Suitably the particles are introduced into a hot gas flow and are carried by this flow for a predetermined time. The division of the hot gas flow from the particle flow is then commenced. Finally, the particle flow is fed through a separator working according to the size of the particles, for the removal of the impurities. System prevents the introduction of foreign bodies into board making machines, and the resulant damage causing long down times. The cleaning process can be carried out in all weathers without problems. No water is used and the process is very economical.
