HZS Concrete Batching Plant | 25-120 m³/h | JS Twin-Shaft Mixer | GZD Factory Price

High-Efficiency Twin-Shaft Forced Mixing System

At the heart of every GZD HZS concrete batching plant lies a JS series twin-shaft forced mixer — the industry benchmark for mixing efficiency and homogeneity. The counter-rotating dual shafts generate powerful convective, shearing, and diffusive forces that achieve 98% concrete uniformity in just 60 seconds per mixing cycle. Models HZS25 through HZS50 utilize JS500-JS1000 mixers (500-1000L discharge capacity), while HZS75 through HZS120 are equipped with JS1500-JS2000 units (1500-2000L), delivering actual production rates of 20-100 m³/h that consistently exceed rated capacity by 10-15%. The mixer lining plates are manufactured from high-chromium wear-resistant alloy steel with a service life exceeding 50,000 batches — three times that of standard steel plates — dramatically reducing maintenance frequency and operating costs over the plant’s 10+ year service life.

Precision Four-System Weighing Architecture

Concrete quality begins with material proportioning. The GZD HZS plant employs four independent weighing systems — aggregate, cement/powder, water, and additive — each calibrated to stringent accuracy standards. Aggregate weighing achieves ±2% precision via a PLD2400-type four-compartment batcher with cumulative weighing capability, while powder, water, and additive scales all maintain ±1% accuracy through fully sealed, moisture-proof weighing hoppers. The additive scale uses stainless steel construction for corrosion resistance, and the water scale integrates a 2.2 kW booster pump for rapid discharge. This quad-scale architecture ensures that every batch meets design specifications for strength, slump, and air content — a non-negotiable requirement for commercial ready-mix supply and infrastructure-grade concrete.

Intelligent Microcomputer Control System

The GZD HZS plant runs on a PLC + industrial computer dual-core control platform that transforms concrete production from manual operation to fully automated execution. The touchscreen interface supports up to 999 formula presets, enabling instant switching between concrete grades (C15-C60) without recalibration. The system automatically executes the complete production cycle — batching, conveying, mixing, and discharging — with real-time monitoring of material levels, motor current, and weighing deviations. Production data logging with USB export capability provides traceability for quality assurance, while the remote monitoring function enables off-site supervision and troubleshooting — particularly valuable for plants operating in remote project locations across Africa and the Middle East where on-site technical support is limited.

Eco-Friendly Modular Construction

Environmental compliance is engineered into every GZD HZS plant. The fully enclosed main structure with pulse jet dust collection system achieves 99.5% dust removal efficiency, keeping airborne particulates well below international occupational exposure limits. The wastewater recycling system enables zero-discharge operation — wash water from the mixer and batching area is collected, settled, and reused in subsequent batches. Operating noise is controlled below 75 dB through vibration-damped mounting and acoustic enclosure of the mixing host. The containerized modular design minimizes foundation work (reducing installation costs by up to 40%), enables relocation within 7-10 days, and allows capacity expansion by adding mixer units or silos as project demands grow — a critical advantage for contractors moving between project sites.

Case 1: Commercial Concrete Supply for Residential Development in Lagos, Nigeria

A Nigerian construction materials company invested in a GZD HZS75 concrete batching plant to supply ready-mix concrete for a 200-unit residential development project in Lagos. The plant was configured with a 100-ton cement silo, belt conveyor feeding system, and diesel generator backup power. During the 14-month project, the plant produced an average of 450 m³ per day across C20, C25, and C30 grades, with zero rejected batches due to the ±1% weighing accuracy. The investor recovered the full equipment cost within 8 months and subsequently secured contracts for two additional residential projects, leveraging the plant’s proven production capacity and the operator team trained during the initial deployment.

Case 2: Bridge Construction on the Addis Ababa-Djibouti Railway Corridor, Ethiopia

For a railway bridge construction project along the Addis Ababa-Djibouti corridor, the contractor deployed a GZD HZS90 concrete batching plant at a remote site 180 km from the nearest city. The plant’s modular design enabled installation within 12 days using only local labor supervised by GZD’s remote video guidance. The belt conveyor feeding system and 150-ton cement silo supported continuous production of C40 bridge pier concrete at 70-80 m³/h actual output. The remote monitoring function allowed GZD’s technical team in Zhengzhou to diagnose and resolve a sensor calibration issue within 2 hours — avoiding what would have been a 3-day downtime event given the site’s isolation. The project completed 15 days ahead of schedule, with all concrete samples passing 28-day compressive strength tests.

Case 3: Dam Spillway Construction in Sulawesi, Indonesia

A hydroelectric project in Central Sulawesi required C25 impermeable concrete for a dam spillway structure, with strict limits on heat of hydration and water-cement ratio. The contractor selected a GZD HZS120 batching plant equipped with an ice-water cooling system and fly ash dosing capability. The plant’s independent additive weighing system enabled precise dosing of water-reducing admixture at 1.2% of cement weight, achieving the target slump of 80±10mm while maintaining a 0.45 water-cement ratio. Over the 8-month construction period, the plant produced 28,000 m³ of specification-grade concrete with a 100% strength pass rate. The pulse dust collection system and wastewater recycling achieved zero environmental discharge — meeting the project’s ISO 14001 environmental management requirement.

Case 4: Precast Pipe Pile Factory in Uttar Pradesh, India

An Indian precast concrete manufacturer expanded production capacity with a GZD HZS50 batching plant to supply prestressed pipe piles for a highway expansion project. The plant was configured with a skip-hoist feeding system and 3-compartment aggregate batcher to fit within the existing factory’s 20×15m footprint. The JS1000 twin-shaft mixer delivered consistent C50 low-slump concrete (slump 30±10mm) on a 72-second cycle, synchronized with the pipe pile carousel production line. The formula storage system enabled rapid switching between pile grades (C50 for standard piles, C60 for heavy-duty piles) without production interruption. The factory increased daily output from 80 to 220 piles, with the equipment investment recovered within 11 months of operation.
