Why is my elbow wearing out?
There are many factors that affect a liner’s wear characteristics. A liner which is working within it’s operational parameters can last 30 years and that’ the natural beauty of rubber lining and why it has been utilized in the mining industry for so many years.
Any of the following will have an affect on the liner life.
Angle of incident: The angle at which the slurry impacts the liner has a large effect on it’s resistance. Rubber is best suited for wet sliding abrasion. Angle of less than 5 deg or greater than 50 Deg have the best lifespan.
Particle Characteristics: Size, Distribution, Profile Characteristics, Hardness, Density of the concentrate and temperature all have an affect on wear.
Type of flow: Is the slurry a laminar flow, turbulent, heterogeneous or a homogeneous mix? What is the flow velocities, these are all factors in liner life.
Pipe Conditions: What is the pipe material or lining material, Durometer? What is the pipe formation, unevenness, bends or slopes? Is the diameter correct for the flow?
Slurry Makeup: Is the material acidic or alkaline. How is the distribution of the particulate? What is the temperature of the slurry?
These are some of the questions and factors which must be considered when choosing a lining material.
