System Features
Modular Design
Each functional unit is an independent module. Combine as needed — easy to expand, upgrade, or reconfigure for maintenance.
PLC Automatic Control
Touchscreen HMI, real-time monitoring of key parameters, remote monitoring and data logging supported.
Closed-Loop High Yield
Grinding + classification in closed-loop operation. Coarse powder recycled, product yield high, raw material waste minimized.
Inert Gas Compatible
Optional inert gas protection module available to meet safety production requirements for flammable or oxidation-sensitive materials.
Turnkey Delivery
Equipment supply, installation and commissioning, operator training, and technical support — all-in-one service.
Test Before Select
Confirm process on small-scale trial first, then configure the production line based on actual test data, reducing start-up risk.

Frequently Asked Questions
What information is needed to purchase a production line?
Essential: material name and safety risks (flammable, oxidation-sensitive), target product particle size (D50/D90/D97 or residue specification), hourly capacity, continuous run duration. Supplementary: on-site air supply, building space, utilities, explosion-proof requirements, cleanliness requirements. The more complete the information, the more accurate the proposal.
What is the typical delivery lead time?
Standard configuration systems typically 8–16 weeks. Highly customized systems (inert gas protection, special materials of construction, advanced automation) may be longer. We recommend confirming the technical solution early in the project to allow sufficient lead time.
Is it possible to run a trial before placing an order?
Yes, and we strongly recommend it. A trial confirms target particle size achievability, capacity trend, and wear risk — making the production line configuration more targeted and reducing commissioning risk after start-up.
Who is responsible for installation and commissioning?
We provide installation guidance and on-site commissioning services, including equipment installation, system integration testing, production trial guidance, and operator training. Specific service scope and costs should be confirmed at the inquiry stage.
How is spare parts and after-sales maintenance handled?
We provide a wear parts list and recommended spare parts inventory. Common wear parts (nozzles, classifier wheels, filter bags, etc.) can be stocked in advance. Complete maintenance manuals are provided before equipment shipment, with remote technical support available.
