The dust emission depending on chip formation resulting from sanding of wood with contact cylinder on a wide belt sanding machine
The work is part of a larger research project and presents a study on the emissions of dust smaller than the PM10 generated in processing of wood sanding. Mathematical model is presented for determining the volume of dust particles and the experimental results of measured concentrations of dust. According to the obtained values by theoretical an experimental research it can be stated that: As the feed rate decreases the lower the distance between two consecutive cycloid. This leads to the formation of smaller wooden chips and a health hazard for workers. The smallest chips are obtained from sanding with removal depths ranging between 0.1 and 0.3 mm, and lower feed speed rates. To avoid this is recommended for advanced high-speed regimes. Material density is directly proportional to the amount of dust (represented by the particle mass) and inversely proportional to the sanding capacity (represented by the volume of chips detached in unit time). Regardless of cutting regime on wood sanding the particles of dust in suspension are present and consequently affect worker health. To reduce the amount of dust in suspension working arrangements should be optimized by taking into account ecological principles to preserve the optimum technical parameters.
