Roller press studs

Roller press nails are the core wear-resistant parts of the roller surface of the roller press (Roller Press), which are used to grind high-hardness materials (such as cement clinker, ore, etc.). It has the following functions:

1. Crushing and grinding: high-efficiency grinding is achieved through high-pressure extrusion of materials.

2. Protect the roller surface: reduce direct wear on the roller surface and extend the life of the roller sleeve.

3. Optimize energy consumption: reduce grinding power consumption (30%-50% energy saving compared to ball mill).

The nails we produce have high wear resistance, impact resistance, high temperature resistance, and easy replacement.

Frequently Asked Questions

Q1: How long is the life of the nail?

A: It depends on the hardness of the material, usually:

Cement clinker: 8,000-12,000 hours

Iron ore: 3,000-5,000 hours (tungsten carbide nails can be extended to 10,000 hours).

Q2: Can the worn nails be repaired?

A: High chromium cast iron nails can be repaired 1-2 times by surfacing welding, and tungsten carbide nails cannot be repaired.

Q3: How to reduce the fracture of cast nails?

A: Choose alloy steel with higher toughness (such as 42CrMo) and control the overload of the roller press.
