First, the abrasive wear of the blade of the spiral sand washer is invalid. This is a common phenomenon in sand washing equipment. Usually, the cause of blade wear is mainly caused by long-term grinding of materials and strong impact force, especially for some sand washing that is often used to grind large-size ore. In terms of machine, it wears faster. Wear of the blade surface causes its size to continue to decrease until it no longer meets the normal production requirements of the sand washer.
Second, the blade's brittle fracture fails. There are three reasons for this problem in the spiral sand washer blade: (1) The sand washing equipment is also subjected to external force and temperature changes caused by the material, resulting in the internal stress of the spiral sand washer blade being continuously increased, eventually causing carbonization. There is a crack in the object. (2) When the spiral sand washing machine processes the castings by heat treatment, it often produces some tiny cracks on the surface. When the cracks are continuously expanded, the blades will fail. (3) If the spiral sand washing machine during the work of the blade portion of the bolt is a Class metal objects stuck, then sand washing machine will have a greater force so brittle failure occurs.
During the working process of the sand washing machine, the impact force of the material can not be predicted in time, so we can not judge it. The failure mode of the blade is an abnormal phenomenon.
The spiral sand washing machine plays an irreplaceable role in the production and classification of ultrafine powder materials. In addition, in order to improve the performance of the sand washing machine, it is necessary to start from the characteristics of its internal flow field distribution, so that a more efficient sand washing equipment can be designed.
This article makes some simple introductions about the reasons for the two blade failures of the spiral sand washer. I hope to help you. At the same time, the failure of the sand washer blades also caused us to think. What factors will have a certain impact on the efficiency of the sand washing machine. Therefore, it is necessary to study a new type of spiral sand washing machine to reduce the production cost of the enterprise.
In the sand production line, whether it is sand washing equipment or sand making equipment, we need to carry out maintenance and maintenance in daily work. If problems occur, we should solve them in time.
Automatic Fitting Fabrication Of Plastics
Fabricated fittings are constructed by joining sections of pipe,machined blocks, or molded fittings together to produce the desired configuration.
Components can be joined by butt or socket heat fusion, electrofusion, hot gas welding or extrusion welding techniques. It is not recommended to use either hot gas or extrusion welding for pressure service fittings since the resultant joint strength is significantly less than that of the other heat fusion joining methods.
Fabrication of Plastics designed for full pressure service are joined by heat fusion. For Hdpe/poly/polyethylene Fitting Fabrication of Plastics, Yuda RGH workshop plastic pipe fitting welders can make elbow, tee, cross and wye fittings in relevant clamps. For eliminating operator errors and increasing productivity, you can choose RGH-A series CNC Polyethylene Fabrication Machines, or Fully automatic HDPE Fusion Fittings Welder with all jaws operated hydraulically for faster welds, precision welding operation, and data logger function.
