How to Choose Roll Covers for a Ball Press Machine

Time：Jan 09,2022

For a briquetting machine, the roller shell is a key component that plays a critical role. The lifespan of the roller shell directly determines how long the machine can be used, making it a wear-and-tear part. Therefore, when choosing a briquetting machine, selecting the right roller shell should be your top priority.

The roller shell materials for the ball press machine include 65Mn, 9Cr2Mo, and high-chromium alloy. Depending on the material provided by the customer, we select the appropriate roller shell material for the ball press machine. Below, we’ll introduce the application ranges of these three types of roller shells one by one:

65Mn is a common spring steel known for its high hardenability. As it falls under the category of cast steel components, 65Mn roller shells are relatively inexpensive and typically used in smaller-scale pelletizing machines—such as those processing materials like coal powder, coke, or wood charcoal powder.

Both 9Luo2 molybdenum and high-Luo alloys are forging components, primarily used in ball press machines that require significant pressure—capable of compacting materials such as ultra-fine powders, calcined magnesium oxide powder, and iron ore concentrates. The 9Luo2 molybdenum-forged roll skin has undergone quenching treatment, resulting in excellent mechanical properties that enhance both toughness and ductility. Long service life, therefore The price is higher than that of 65 manganese.
