The unloader is divided into two series square flange and the circular flange, a total of 48 kinds of specifications. Pressure output system or negative output system, it is the most advanced tripper, one of the important equipment in the dust as the dust removal system. Particularly suitable for powder materials and granular materials, such as environmental protection, metallurgy, chemical industry, roads, drying equipment, and other industries. Star unloading device is the rotation of the impeller, plays a delivery of materials and sealing. It is very easy to dust or particles in the state of pressure continuously and smoothly discharge is an important device in pneumatic conveying and ventilation dust in the network. Star unloader adopts steel plate welded structure leaves a good wear resistance blade and shaft rigid connection structure compact work and reliable portable energy-saving. Star unloader rely on the gravity of the material and the mandatory role of feeder institutions, the cabin materials are unloaded and continuous and uniform flow of the next device, but also as a variety of mill dryer, hopper equipment such as unloading equipment. I produced the star-type unloader iron welding, cast iron, stainless steel welding, chain structure a variety of structural styles, effective solution to the discharge problem of high temperature corrosion. My company's unique production to check the holes designed to make customers more intuitive observation to discharge status and discharge, and improved design star discharge by the company, drawing on advanced domestic and international experience, are handsome in appearance and generous , compact structure, safe and reliable to use, light weight, large capacity and low power consumption.
