In the concrete mixer life cycle, the equipment itself will gradually changes and became damaged by forces or is affected by the nature whether it is in use or idle. This kind of loss is known as visible wear, which gradually changes in the physical condition, and can be divided into service wear and natural wear. Concrete mixer friction, vibration, fatigue are very common in use, grinding of materials, operation of the machine will cause the equipment spare parts friction wear, this kind of visible wear is service wear as we said, and will change concrete equipment parts shape and size, (such as mixer blades)always lead to accuracy decline and poor performance of the equipment, and even damage spare parts , then will result in serious accidents.

The main factors that affect the service wear development degree are: equipment quality, load level, technical level of workers, working environment, maintenance quality and cycle, etc. Corrosion and wear does a great damage to petroleum and petrochemical industry, with the increase of oil and gas development period and the equipment service life, petroleum pipeline and pumping well casing wear and corrosion grows more and more serious.

Extensive corrosion,aging, natural conditions decay are found due to inappropriate keeping, this all known as the natural wear, it will happen whether it is in use or idle, and  much more obvious than in use.
