What Wear-resistant Material Is Better For The Wear-resistant Elbow Of The Powder Feeding Pipe?

The wear-resistant elbow of the powder feed pipe mainly starts from the air box at the outlet of the pulverized coal mixer and the powder exhaust fan to the burner and the tertiary air outlet and connects the recirculation air duct from the outlet air box of the powder exhaust fan to the inlet of the coal mill. The elbow part in the pipeline, because it mainly transports solid powder media, has relatively strong abrasion strength. The selection of wear-resistant materials for the powder-feeding pipeline wear-resistant elbow should have high toughness and impact resistance, high hardness and cutting Strong wear-resistant ceramic material.

The wear-resistant elbow of the powder-feeding pipe is lined with wear-resistant ceramic material. The wear-resistant performance of the powder pipe is very good, the hardness reaches about HV1800, and the wear resistance is more than 10 times that of ordinary steel; it also has good Impact resistance, even in harsh working conditions, you can easily face it; corrosion resistance is also particularly good, after lining wear-resistant ceramics, it will not react with acid and alkali, and will not be oxidized, resulting in The rust is mixed into the pulverized coal, causing incomplete combustion.

The use of wear-resistant ceramics as wear-resistant materials for powder-feeding pipe wear-resistant elbows is the most cost-effective choice. Wear-resistant ceramics can make the inner wall of the pipe very smooth and smooth without causing powder bulk material. The use effect is very good. The service life is very long, generally about 10 times that of ordinary elbows. Wear-resistant ceramics are currently one of the most popular wear-resistant materials for powder-feeding pipe wear-resistant elbows.
