Belt Vacuum Filters & Thickeners in Coal Industry Applications

Publish Time: 2025-07-09 Origin: Site

1. Industry Overview

Industry Trends

Growing Environmental Regulations: Stricter policies (e.g., zero liquid discharge) demand efficient coal slurry dewatering and water recycling.

Resource Utilization: Dewatered coal slime (15–22% moisture) is increasingly reused for power generation or brick making.

Core Requirements

Requirement	Belt Vacuum Filter	Thickener
Feed Solids	15–30%	1–5% (pre-concentration)
Output Moisture	18–25% (coal slime)	N/A (output: 20–30% slurry)
Capacity	50–200 t/h	100–5000 m³/h
Key Goal	Final dewatering	Slurry thickening + water recovery
