Explore our industry-leading road engineering and batching infrastructure machinery designed for precision performance and structural durability.
Founded in 1998, HEM Group (originally established as Xi'an Hongda Communications Technology Co., Ltd.) was born out of a strategic collaboration between leading highway engineering professors from Chang'an University and veteran industrial road construction experts. As one of China's pioneer high-tech enterprises focused on the independent research, design, and manufacturing of road machinery, our organization has fundamentally shaped modern pavement technology.
In 2006, the Shaanxi Provincial Department of Science and Technology officially certified HEM Group as a High-Tech Enterprise. To meet surging demand across international markets and streamline global commercial operations, HEM Group established its specialized export sales division—HME TOP Machinery Equipment Co., Ltd.—in 2017. Today, HME TOP leads international technical exchanges, self-operated machinery exports, global logistics, and field technical support services.
Proprietary dynamic load distribution systems guarantee structural integrity under continuous thermal expansion and dynamic impact from high-capacity mixing modules.
Intelligent torque and fuel management algorithms optimize drive-train efficiency, reducing thermal waste and operational energy consumption by up to 18% per batch cycle.
Fully automated PLC systems integrated with SCADA telemetry monitor every phase: cold feeder dosing, drying drum burner modulation, screening efficiency, and precise bitumen injection.
The asphalt mixing sector is undergoing a profound paradigm shift driven by stringent municipal environmental mandates, rising energy costs, and the urgent global mandate to achieve net-zero infrastructure development. As a leading asphalt batch plant factory, HEM Group stays at the forefront of this industrial transformation by embedding key technological shifts into every batching system we manufacture:
Reclaimed Asphalt Pavement (RAP) recycling is no longer optional. Modern batch plants require specialized recycling ring collars and parallel recycling drums capable of processing 30% to 60% RAP without degrading virgin binder chemistry or causing blue smoke emissions.
By incorporating water-foaming bitumen systems and chemical additives, WMA allows production temperatures to drop by 20°C to 40°C. This yields a 30% reduction in burner fuel consumption and significantly lowers VOC emissions during paving.
Advanced pulse-jet baghouse dust collection systems utilizing Nomex filter media achieve particulate emissions lower than 15 mg/Nm³, complying with stringent European Union and US EPA clean air standards.
Modern asphalt plants are moving away from traditional heavy oil toward multi-fuel flexibility, allowing seamless switching between Natural Gas (LNG), Heavy Fuel Oil (HFO), Diesel, Coal Dust, and green Hydrogen-blend fuels.
A high-performance asphalt batch plant operates as a synchronized ecosystem. Each module must perform impeccably to maintain homogeneous mix temperatures, accurate particle size distribution, and consistent bitumen coating. HEM Group manufactures modular batch plants ranging from 80 t/h to 400 t/h capacity.
Features variable-frequency speed control (VFD) drive motors for individual hoppers, aggregate shortage alarm sensors, and self-cleaning bin walls to ensure smooth feeding of stone fractions.
Equipped with custom-designed internal flighting (lifting blades) optimized for maximum heat transfer efficiency, reducing fuel consumption while thoroughly drying aggregates to <0.5% moisture content.
Enclosed multi-deck screen structure driven by dual eccentric vibration motors, delivering precise particle separation into 4 to 6 hot storage bins with zero cross-contamination.
Independent high-accuracy load cells weigh aggregates, mineral filler, and liquid bitumen. The heavy-duty twin-shaft pugmill utilizes wear-resistant Ni-Hard paddle arms to deliver homogeneous mixing in just 45 seconds per batch.
When international road contractors, government ministries, and commercial quarry operators evaluate an Asphalt Batch Plant supplier, initial Capital Expenditure (CAPEX) represents only 20-30% of lifetime asset cost. Operational Expenditures (OPEX)—including burner fuel consumption, electric power demand, wear parts longevity, and unscheduled downtime—dominate Total Cost of Ownership (TCO).
HEM Group drums utilize ceramic fiber insulation blankets combined with optimized flights, keeping diesel consumption below 5.5 kg per ton of finished hot mix asphalt at standard operating moisture levels.
Pugmill liner plates, mixer tips, and screen mesh panels are forged from high-chromium alloy (HRC ≥ 62), providing an operational service life exceeding 200,000 metric tons of aggregate output.
Our plants feature containerized modular structures designed to fit standard 40ft HQ shipping containers, reducing international freight costs by up to 35% and allowing rapid site commissioning within 14 days.
Infrastructure projects operate under strict contractual deadlines. A single day of plant downtime can jeopardize multi-million-dollar paving contracts. HEM Group provides a robust global service network designed to ensure uninterrupted operation.
We maintain direct distribution teams and regional spare parts hubs across key export markets including Russia, Malaysia, South Africa, Uzbekistan, Ghana, Kenya, Indonesia, and Sri Lanka.
Every batch plant comes equipped with remote cloud diagnostics modules, allowing our factory automation engineers to troubleshoot PLC logic, calibrate load cells, and update system software anywhere in the world.
Our senior engineering teams conduct on-site foundation design verification, mechanical assembly, cold/hot testing runs, and comprehensive safety certification training for local operating personnel.
Beyond high-efficiency asphalt mixing plants, HEM Group offers a complete turnkey product line covering earthmoving, crushing, aggregate screening, pavement laying, and preventative maintenance machinery.
Our road equipment portfolio includes Asphalt Pavers, Intelligent Bitumen Distributors, Cold In-Place Recyclers (CIPR), Road Milling Machines, Paver Feeders, Synchronized Chip Sealers, and Micro-Surfacing Slurry Pavers designed for expressway construction and urban restoration.
Comprehensive heavy equipment solutions featuring Wheel Loaders, Backhoe Loaders, Heavy Bulldozers, Steel Drum Rollers, Mini Excavators, and specialized Walking Excavators (Iron Spider-Man) for harsh terrain emergency rescue.
Mobile Jaw Crushers, Mobile Roller Crushers, and Mobile Primary Vibrating Screens built for heavy-duty quarry operations, concrete recycling, and precise aggregate size preparation prior to asphalt batching.
As digital transformation reshapes civil engineering, HEM Group is pioneering AI-integrated asphalt production technologies that will define the next decade of road construction:
Integrating continuous microwave sensors in cold aggregate feed bins to instantly adjust thermal burner output and binder ratio calculations in real-time, counteracting ambient humidity variations.
IoT sensors attached to dryer drum trunnion rollers, vibrating screen bearings, and mixing shafts continuously monitor acoustic signatures, alerting maintenance teams to component wear weeks before failure.
Automated control software computes the CO2 equivalent emissions per ton produced in real-time, generating verified environmental compliance certificates for municipal green infrastructure projects.
