300ZJ & 250ZJ Slurry Pumps for TISCO State-Owned Iron Ore Concentrator

Description

- Commodity name: 300ZJ & 250ZJ Slurry Pumps for TISCO State-Owned Iron Ore Concentrator
1. Project Overview
Client: Taiyuan Iron & Steel Group (TISCO) – Large state-owned iron and steel enterprise in China
Project Site: Major iron ore concentrator in Shanxi Province, supporting TISCO’s raw material base
Plant Capacity: 3,500 tons raw iron ore processing per day
Process Flow: Crushing → staged grinding → magnetic separation → flotation → thickener concentration → tailings transportation
Applied Pump Models (Hebei Xingou Machinery)
300ZJ Horizontal Heavy-duty Slurry Pump: Mainly used for large-flow hydrocyclone feeding and primary mill discharge delivery
Supply Scope
250ZJ-I-A70: 12 sets (9 running, 3 standby)
Operation Status: Full-load continuous stable operation for 20 months, fully passing state-owned enterprise safety and efficiency assessment
2.1 Severe Mining Slurry Working Conditions
Solid particle size: up to 40 mm
Slurry specific gravity: SG 1.45–1.55
Operation mode: 24/7 non-stop continuous production
Short wear life: Ordinary alloy pumps only ran 30–40 days, frequent replacement of impellers and liners caused unplanned downtime and restricted concentrator output.
Severe slurry leakage: Traditional packing seals failed under high-density slurry, causing site pollution and frequent manual maintenance.
Disordered spare part standard: Mixed brands of original equipment caused inconsistent spare part specifications, increasing inventory and management costs for state-owned plant.
3.1 High-chrome Anti-abrasion Upgrade
3.2 Enhanced Anti-leakage Sealing System
3.3 Large-flow High-efficiency Hydraulic Optimization
3.4 Unified Standard Configuration & Intelligent Control
3.5 Standardized After-sales Service for State-owned Enterprises
4.1 300ZJ-I-A85 (Main Hydrocyclone Feed & Mill Discharge Pump)
Selection reason: 300ZJ large-caliber wide-flow design is specially suitable for high-concentration coarse particle ore slurry. It features super strong passing capacity, stable overload resistance and no blockage, fully meeting the core high-load feeding demand of large hydrocyclone groups.
Working condition matching: Stable medium-large flow delivery, actual flow 550–700 m³/h, rated head 38–45 m, matched 110kW motor.
5. Project Benefits & Customer Feedback
Lower comprehensive operating cost: High-efficiency hydraulic design reduces power consumption, and extended wear part service life greatly cuts annual maintenance and replacement costs.
Zero leakage & clean production: Reliable sealing system eliminates slurry splashing, improving workshop environmental assessment standards.
Hebei Xingou 300ZJ and 250ZJ large-flow heavy-duty slurry pumps fully adapt to high-abrasion, high-density and weak alkaline iron ore slurry working conditions. With reliable hydraulic performance, super wear-resistant structure and standardized supporting system, they have become stable and cost-effective pumping solutions for large state-owned iron ore concentrators, and can be widely applied in large-scale grinding classification, thickener underflow transportation and tailings discharge working conditions in mining industries.
