Equipments wear in mineral processing operation
In a mineral processing plant ， the activities unavoidably result in wear. And wear costs money.Often lots of money. This is related to the structure of rock, ore or minerals, being crystals normally both hard and abrasive. The wear is especially much more in hard ore such as iron ore processing and gold ore processing plant. Why wear at all? Wear is caused by the normal rock stress forces • Compression (1) • Impaction (2) • Shearing (3) • Attrition (4) in combination with mineral hardness and energy! Wear in operation caused by: 1.Wear by Compression Metals and compression Manganese steel: The first option for compression wear is manganese steel. This alloy has a very special property, being self hardening and self healing when exposed to large amounts of compression and impact energy. Normal standard is a 14% Mn alloy which is first option in most crushing applications. 18 % Mn alloy is a harder but also a more brittle alloy used in applicatio...
