90m³/h Precast Metro Segment Concrete Batching Plant Launched for Large-Scale Shield Tunnel Lining ProductionWith the booming global metro and underground shield tunnel construction market,CO-NELE company releases a customized 90m³/h precast segment concrete batching plant, specially optimized for mass production of subway tunnel lining segments. This mixing station adopts vertical planetary mixer as core mixing unit, solving the strict homogeneity, low air void, high impermeability requirements of steam-cured C50/C60 tunnel segment concrete, delivering stable 90 cubic meters per hour continuous output for large precast segment factories worldwide.
1. Core Configuration of 90m³/h Segment Dedicated Batching Plant
1.1 Vertical Planetary Mixer for Tunnel Segment Concrete
Traditional twin-shaft mixers cannot eliminate mixing dead angles, resulting in excessive bubbles and uneven strength of tunnel segments. Our matched CMP planetary mixer realizes full-range uniform mixing, low slump loss, no segregation, perfectly fit steam curing segment production process.No dead zone mixing structureLow air content finished concreteStable mixing performance for stiff segment concrete
1.2 Ultra-Precise Weighing & Dosing System for High-Strength Segment Concrete
Metro tunnel lining requires strict raw material proportion to reach P10/P12 anti-permeability standard. This 90m³ plant equips independent micro-scale admixture weighing unit, aggregate, cement, fly ash weighing error controlled within ±0.5%.Multi-group segment concrete formula storageAutomatic water compensation based on aggregate humidityReal-time data recording for quality traceability
1.3 Full Closed Environmental Protection System
Designed for indoor precast workshop, complete dust removal, sand stone separator and sewage recycling system, zero waste discharge, meet global environmental production standards for precast factories.

Q1: Why use planetary mixer instead of twin-shaft mixer for tunnel segment production?
A1: Tunnel segment concrete is stiff, high-strength and needs low bubble rate. Planetary mixer has no mixing dead angles, higher homogeneity, effectively avoid honeycomb and pitting on segment surface after steam curing. Twin-shaft mixer is more suitable for ordinary ready-mix concrete.Q2: Is 90m³/h batching plant enough for medium-scale segment factory?
A2: 90m³/h stable output can support daily production of 300–600 standard metro segments, matching most medium-sized subway precast production lines. For super-large factories, we can customize 120/180m³/h segment special mixing station.Q3: Can this mixing plant store multiple formulas for different lining grades?
A3: Yes, the automatic control system stores unlimited groups of mix designs, support C50, C60, impermeable P12, low-shrinkage UHPC segment concrete one-click switching.The 90m³/h precast metro segment concrete batching plant is a targeted solution for underground infrastructure precast manufacturers. It balances production efficiency, concrete quality and environmental standards, becoming the preferred mixing equipment for global subway tunnel projects.
