Automatic Fire Assay Bead Rolling Mill for Gold and Precious Metal Testing

The Automatic Fire Assay Bead Rolling Mill is a high-efficiency machine specially developed for processing fire assay precious metal beads into thin metal sheets. It is widely used in gold assay laboratories, precious metal refineries, mining laboratories, and metallurgical testing facilities.

Unlike traditional manual rolling methods that require multiple passes and intensive labor, this advanced Fire Assay Bead Rolling Machine completes the rolling process from bead to sheet in one continuous operation. It greatly improves production efficiency, ensures consistent sheet thickness, and reduces operator workload.

High-Efficiency Automatic Rolling System

The machine adopts a fully automatic linked transmission system driven by a powerful motor, precision gearbox, chain transmission, gear mechanism, and universal joints. Four pairs of rolling rollers work synchronously to provide stable and uniform rolling performance.

The optimized rolling structure allows fire assay beads to be directly converted into flat sheets, significantly increasing processing speed compared with conventional rolling equipment.

Key Features of the Automatic Fire Assay Rolling Mill

1. One-Step Bead-to-Sheet Rolling

The machine transforms fire assay beads into sheet material through a single continuous rolling process, improving efficiency and reducing material handling steps.

2. Automatic Lubrication System

Equipped with a computerized high-pressure automatic lubrication system, the machine continuously supplies oil to roller bearings and universal joints, ensuring smooth operation and extending component service life.

3. Stable and Reliable Performance

The maintenance-free gearbox design reduces maintenance requirements, minimizes operating failures, and provides long-term stable performance in demanding laboratory and industrial environments.

4. Safe and Easy Operation

The control panel uses a safe 36V low-voltage control system with forward, stop, reverse, emergency stop, and power indicator functions. The simple operating interface allows workers to operate the machine after basic training.

5. Durable Industrial Construction

The machine features:

• Heavy-duty steel frame
• Stainless steel protective covers
• Hard chrome-plated exposed components
• Corrosion-resistant surface treatment

This ensures excellent durability and a long service life.
