The equipment that crushes or grinds your dry bulk material takes a real beating, often leading to equipment downtime and high replacement and refurbishment costs. Applying hard facing via welding to your size reduction equipment surfaces can improve your operation's efficiency by lengthening the equipment's service life and keeping your maintenance costs under control. This article discusses abrasive and impact wear in size reduction equipment and how to choose and apply a hardfacing alloy.

While several types of wear can affect bulk solids processing equipment, size reduction equipment is most often affected by either abrasive wear or impact wear — and often by both. The wear can lead to frequent replacement or refurbishment of equipment surfaces and components, such as liners, hammers, and crusher rolls, increasing your operation’s downtime and maintenance costs.
