Spiral Classifier FG-500 for Copper Ore Processing

I. Project Overview

Project Location: Shaoguan, Guangdong

Main Contractor: BGRIMM Machinery & Automation Technology Co., Ltd.

Product Name: Spiral Classifier

Product Model: FG-500

Scope of Supply: Complete equipment unit

II. Project Description

For a mineral processing plant project in Guangdong undertaken by BGRIMM Machinery & Automation Technology Co., Ltd., the client conducted multiple inspections and ultimately selected Zhengzhou Mining Machinery's Spiral Classifier FG-500. This classifier works in conjunction with the client's existing ball mill to form a closed-circuit system, classifying ground copper‑sulfide ore after milling.
