Product Description

Captivating Introduction
Our Micro Powder Grinding Mill, meticulously crafted by the adept minds at our R&D department, stands as a testament to innovation and rigorous testing. With accolades from thousands of satisfied customers, this machine exemplifies superior features, unparalleled stability, user-friendly operation, and hassle-free maintenance. It is, without a doubt, the quintessential choice for achieving precision in fine powder milling.
Comprehensive Scope
The HGM Series Micro Powder Grinding Mill is a specialized device for producing fine and superfine powders from materials that are non-inflammable, non-explosive, and brittle, with a Moh's hardness rating below six. This includes a diverse range of over 100 materials such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite, vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, Kalium ore, pumice, and fly ash.
Remarkable Features
· Exceptional Efficiency
With identical final size and motor power parameters, our micro powder grinding mill offers a capacity twofold of that seen in jet mills, mixing grinders, and ball mills, all while achieving a 30% reduction in energy consumption.
· Extended Spare Parts Longevity
Crafted from specially selected materials for high utilization, the ring and roller boast a lifespan approximately one year, which is 2-3 times longer than that of an impact mill or turbo mill. For grinding calcite carbonate, the lifespan extends remarkably to 2-5 years, though it does vary based on the hardness of materials.
· Unmatched Safety and Reliability
The grinding material's final fineness is adjustable within a remarkable range of 200 to 2500 mesh (74-5 microns).
· Environmentally Conscious Design
With the strategic application of a pulse bag filter and muffler, our machine significantly reduces dust pollution and noise, contributing to a cleaner and quieter environment.
· Cutting-Edge Intelligent Speed Control
This feature ensures even material feeding into the machine and adjusts the main speed according to the material being ground, resulting in more stable fineness. Consequently, this enhances capacity and efficiency while minimizing power consumption.
