Its conveying distance ranges from 2 meters to 70 meters. Manufactured according to customer needs. How to solve the problem of material blocking in the screw conveyor: How to solve the problem of material blocking in the screw conveyor is a kind of conveying equipment with a wide range of uses in the mining, feed, grain and oil, and construction industries. The screw loading conveyor is suitable for particles and powder. The horizontal conveying and vertical conveying of lumpy and small materials are skewed conveying and vertical conveying. The conveying distance ranges from 2 meters to 70 meters, and there are various specifications and can be manufactured according to customer needs. A common fault is blocking. There are many reasons for blocking. The following measures can be adopted to prevent blocking:    An anti-blocking valve is opened on the discharge end cover. Strictly implement the operating procedures to achieve no-load starting and no-load parking; to ensure continuous and even feeding. When blocking occurs, because of the accumulation of materials, the anti-blocking door is opened, and the power supply is blocked by the travel switch. Reduce the horizontal size of the central suspension bearing as much as possible to reduce the possibility of material blocking when the material passes through the central bearing. Choose various technical parameters reasonably, such as slow speed not too large.   Necessary cleaning of the materials entering the loading conveyor to prevent large or fibrous impurities from entering the machine and causing blockage. Install silo level device and blocking sensor to complete automatic control and alarm. Enlarge the discharge port or lengthen the end of the trough to solve the problem of poor discharge or too late to discharge. At the same time, a small anti-rotation blade can be installed at the end of the trough of the discharge port to prevent the end from blocking the material.
