Triboelectrically-induced reduction of fine dust during cutting processes
Abstract
All cutting processes deliver respirable dust particles. These particles are currently insufficiently exhausted, which may cause at permanent exposure severe health damages. We proved that triboelectric charging during cutting processes leads to repulsive forces of wood particles, which provokes a greater dust dispersion, and a reduced dust sedimentation process. The idea is through targeted opposite-poled charging of wood particles, at the time when the particles emerge - directly at the cutting tool, to create targeted attraction forces among the particles. The application-focused basic research approach is dedicated to triboelectric rankings, to charging phenomena of ligno-cellulosics, to separation behavior at various conditions, and to visualization of dynamic particle movements. Particle agglomeration is leading to reduced fine-dust loads, to faster particle sedimentation, to reduced “dust clowd” formation, and to a better dust removal, in combination with an increased energy efficiency of suction systems, due to a reduced dust-filter loading.
