What are liner bolts?
Liners (linings) in grinding mills are held in place with the help of liner bolts, which are the most frequent type of bolt used in the mining sector. They are also utilized in the industry of scrap metal, where they are known as shredder bolts since they are commonly found in auto shredders and other types of industrial shredders.
A liner bolt is a head that has been hot-forged from homogeneous grain flow using a flow line that has not been broken in order to make the head more robust, to prevent failure, and to enhance strength. It has been completely CNC machined from oversize material, which guarantees that there will be no de-cementation or surface cracking.

The top liner bolt manufacturers in India offer a wide selection of liner bolts that are made from materials of the highest quality. The following are some benefits of doing as said: prevents “dashing” brought on by slurry spilling from the jolt apertures carries a controlled level of load across the entire perimeter of the pocket base, eliminating the potential of point stacking toward the base of the liner pocket. The bushing’s “housing” impact helps carry the weight and prevents self-relaxation. has been demonstrated to outperform a standard bolt jolt in field applications.

Manufacturing process of fishtail liner bolts
The production process in brief:
- Uncoiled, straightened, and length-cut wire.
- Steel is shaped using the cold forging technique at room temperature.
- Bolt head – Formed gradually by applying tremendous pressure to the steel as it enters various dies.
- Threading: Rolling or cutting is used to create threads.
- Heat treatment: To harden the bolt’s steel, it is heated to an excessive temperature.
- Surface treatment – Depending on the use. To boost corrosion resistance, zinc plating is frequently used.
- After quality inspection to assure consistency and homogeneity, the bolts are then packaged.
