With the theme “Smart Manufacturing in Lüliang, Powering the Future,” the event brought together 173 exhibitors, creating a specialized platform that integrates technology showcases,成果 transformation, and industry matchmaking, thereby facilitating precise alignment across the energy equipment value chain. Shanxi Jinyun’an Fan Co., Ltd. made a prominent appearance at Booth E-021, presenting three core products and, backed by its solid technological foundation and professional service ethos, delivered an impressive performance at this premier energy‑equipment forum.

 

 

Main Ventilator: The “Stabilizing Pillar” of the Mine’s Breathing System

The explosion-proof axial‑flow main ventilation fan exhibited this time is Shanxi Jinyun’an’s flagship product in the field of mine ventilation. Featuring an exhaust‑type ventilation configuration and a direct‑drive coupling between the impeller and the motor, it boasts a compact design and smooth, reliable operation. The unit is equipped with an integrated manual/automatic braking system that enables normal startup and reverse‑flow ventilation within five minutes, with a reverse‑flow rate exceeding 60% of the forward‑flow volume, thereby providing robust safety assurance for underground mines. In terms of blade design, aerodynamic optimization was performed based on low‑speed cascade test data from the U.S. NACA, employing a large‑section, three‑dimensional twisted airfoil structure. Both the blades and the blade roots incorporate safety factors of at least 13 times the allowable stress. The impeller achieves a balancing quality grade of G4, surpassing the national standard requirement of G5.6, ensuring stable, high‑efficiency operation throughout the fan’s entire service life while keeping it safely outside the surge region.

 

 

 

At the exhibition, the technical team provided visiting customers with a detailed overview of the customized fan selection and design process—optimizing parameters based on the mine’s resistance characteristics to ensure the fan operates efficiently under both minimum and maximum negative pressures. Several technical managers from coal‑mining enterprises engaged in in-depth discussions on key performance indicators such as airflow regulation and reverse‑flow performance, highly praising the product’s adaptability to complex operating conditions.

Hexagonal Local Ventilator: A Masterpiece of Modular Design

The detachable, low-noise local exhaust fan stands out thanks to its distinctive, ingeniously crafted design and exceptional performance. Featuring a modular architecture, its sound‑attenuation system is fully enclosed, effectively controlling both airflow noise and motor‑generated noise. Its innovative detachable design simplifies maintenance, addressing the common challenges of conventional fans—namely, reduced noise‑reduction efficiency due to coal dust buildup and high maintenance costs. At the trade show, many customers personally experienced the assembly and disassembly of the sound‑damping components, repeatedly praising the fan’s “quick‑to‑remove‑and‑replace, convenient and practical” design philosophy.

 

 

 

 

Mining Wet Dust-Removal Fan: Effective Dust Control, Protecting Your Breath

Addressing the longstanding challenges of dust control in underground coal mines, Jinyun’an’s independently developed wet‑type dust‑removal fan—boasting “high‑efficiency dust capture and low‑resistance, energy‑saving operation”—has emerged as another flagship technological offering at the exhibition. This equipment is primarily deployed at dust‑intensive sources such as mining faces, shotcrete work areas, and transfer‑transport zones. It draws in dust‑laden air, mixes it with a water mist, and employs cyclonic separation to purify the airstream, achieving on‑site air cleaning. Its atomization system eschews high‑pressure sprayers; instead, a high‑speed motor drives a micro‑perforated swirl‑water‑throwing cylinder and an axial‑flow impeller, using centrifugal force and airflow entrainment to atomize the water. This eliminates the need for routine maintenance tasks like filter‑media replacement and nozzle clogging that plague conventional dust collectors. In terms of purification performance, the system combines multi‑stage filtration with centrifugal separation, boosting the capture efficiency for respirable dust by more than 20% compared with traditional units. An optimized impeller and flow‑channel design reduces operating resistance by 15% and significantly cuts energy consumption. Key components are crafted from wear‑resistant, corrosion‑proof materials, substantially extending service life and lowering mine‑site operational costs. At the trade show, the technical team engaged in several rounds of in‑depth discussions with visiting customers regarding dust‑control solutions. Several technical managers from mining enterprises expressed strong approval of the equipment’s adaptability to complex dust‑generation conditions and its low‑maintenance characteristics.
