What key points should be followed in the selection of gear production materials?

The most important thing in gear production process is to select good materials. Only with good materials can we produce high quality gears. For the selection of materials, the main points are as follows: 1. Meet the technological performance of gear material The technological properties of materials refer to the ability of materials themselves to […]

Ball mill pinion

Pinion gear is one of the indispensable spare parts of ball mill equipment, according to the direction of tooth shape can be divided into straight teeth and oblique teeth, there are two kinds of key type and expansion type. Different specifications of the ball mill selection of pinion teeth and modulus are not the same. […]

What is the difference between casting and forging?

Casting is the process where metal is heated until molten. While in the molten or liquid state it is poured into a mold or vessel to create a desired shape. Forging is the application of thermal and mechanical energy to steel billets or ingots to cause the material to change shape while in a solid […]
