The abrasive wear failure of the blades of the spiral sand washer is a common phenomenon in the sand washing equipment. The reason for this phenomenon is that the blades have been rubbed by materials for a long time and have been strongly impacted during the cleaning process, especially some larger particle sizes. The sand washing machine has a fast wear speed, and the wear is serious, and the blade surface will affect the normal production requirements of the sand washing machine. There are three main reasons for the failure of the spiral sand washer blade: 1. The external force on the sand washing equipment or the temperature change caused by the material may increase the internal stress of the spiral sand washing machine blade, resulting in carbide cracking. 2. When the spiral sand washing machine adopts the heat treatment method, cracks may occur on the surface of the casting, and continuous cracking may cause the blade to break and fail. 3. If the blade part of the spiral sand wa...

As high-standard screening equipment, the screening machine can also be used for the screening and grading of raw materials and bean husks in large oil plants, as well as for the screening and grading of large-granular urea in chemical industry, powdery materials or pellet feeds in feed factories. It can also be used for the initial cleaning of raw materials in feed mills and the classification of intermediate products after secondary crushing in large and medium-sized feed mills. In addition, it can also be widely used in food, heavy alkali, large particle urea, small particle urea, ceramsite, zirconia, reduced iron and titanium powder, barite, food and spices, chemical industry, plastics, mining, rubber, wood and Screening and grading of raw materials and finished products in various industries such as plywood, medicine, sugar, mining, and paper. With the development of the market circular economy, screening and screening in the waste plastics industry are increasing day by day, and ...

method to  slove the blockage of the screw feeder 1. Reasonably select the technical parameters of the screw feeder, such as the speed of the slow screw conveyor should not be too large. 2. Strictly implement the operating procedures to achieve no-load start and no-load parking; ensure that the feeding is evenly continuous. 3. Increase the discharge port or lengthen the end of the trough to deal with the problem of poor discharge or too late to discharge. At the same time, a small section of counter-rotating vanes can also be installed at the end of the material trough at the discharge port to prevent the material from being blocked at the end. 4. Make necessary arrangements for the materials entering the screw feeder to prevent large debris or fibrous impurities from entering the machine and causing blockage. 5. Reduce the lateral size of the central suspension bearing as much as possible to reduce the possibility of material blocking when the material passes through the central b...
