Because the screw mixer has the advantages of large loading coefficient, high mixing uniformity, fast mixing speed, convenient installation and maintenance, low energy consumption, etc., it is widely used in pharmaceutical, food, fine chemical, petrochemical, pesticide, paint, cosmetics, plastic, Pigments, feed and other industries. However, with the development of the production process, many processes require equipment not only to have a good mixing function, but also to have a quick heating and drying function. In the past, the heat transfer jacket was usually provided on the outside of the mixing cylinder, and the heat transfer efficiency was low. It takes a long time to complete the mixing and drying function; or it can be dried by mixing with a ribbon mixer and then placed in a drying device, which increases the investment cost and increases the workload. In response to the above situation, Nantong Ross developed an internal heating ribbon mixer. Heat transfer medium (such as hot water, heat transfer oil, steam, etc.) is introduced into the jacket outside the mixing cylinder and into the hollow screw strip, and is rapidly heated when the material is reversed, continuously convected, and pumped through the cover. The vacuum port takes the water vapor away in time, so that the material can be dried and mixed in a short time.
◆The machine is driven by the reducer to directly rotate the agitator.
◆ Wide application range, can be used for mixing powder and powder, powder and liquid, and also as reaction equipment and drying equipment.
◆The spray device can be added according to the user's requirements to spray an appropriate amount of liquid into the material.
◆Good mixing uniformity. It can be mixed evenly with materials of 1:10000 ratio, especially for mixing materials with different specific gravity.
◆The mixing process is relatively mild and the material is less broken.
◆ If the material is easy to agglomerate, a chopping device can be added to the mixing cylinder.
Dimensions and related technical parameters refer to the 42A series screw strip mixer. For material conditions (such as specific gravity greater than 1.5, high viscosity, particle size greater than 5mm, etc.), you can consult Nantong Ross.
