Drum dryer is widely used in food, feed, chemical, pharmaceutical, mining and other industries. Equipment working process is as follows: the wet material after joining dryer after dehydration, inside the cylinder under uniform of copy board flipping, material in the dryer evenly dispersed in contact with the hot air fully, to speed up the drying heat transfer, mass transfer. In the process of drying, copy board and heat properties of materials with gradient, under the action to the drying machine another star discharge valve to discharge the finished product.
SKB Gear adopts the latest manufacturing technology and established our enterprise standards for products. We have recognized the significant effect of quality on our existence and have established our quality management system in accordance with GB/T 19001-2008-ISO9001:2008. Our Goals is that continual innovation and development to lead the industry of welding pipes in the 2600mm diameter of the large dryer gear.
