The long belt sanding machine is one of the oldest types of industrial machinery still in widespread use today. The early machines were used for creating high quality furniture, but they didn’t offer the same speed and accuracy that modern machines are capable of.
During the early days of their use, long belt sanders were fitted with a ventilator in order to catch dust before it could escape into the air. Now, however, a dedicated extraction unit with a hood combine to capture dust and store it away. However, the process of sanding causes an enormous amount of dust, so larger production facilities will often have an additional extraction machine in operation. This extra protection is essential, as excess dust can lead to respiratory problems and the breakdown of other machines in the production facility.
A lot of small and medium-sized operations use second-hand machines because the long belt sander is such a reliable workhorse. Sanding technology hasn’t really changed much during the last 50 years, so even the oldest machines around are still performing well. There are some companies that prefer the wide belt sander, but they will usually have a long belt sanding machine on standby in case something goes wrong.
