Product Overview
The SLVTM Micro Powder Ultra-Fine Grinder is a highly efficient, low-cost ultra-fine powder processing equipment developed by our company. Drawing upon over two decades of grinding mill manufacturing expertise and incorporating the strengths of domestic and international grinding mill producers, it was created through extensive investigation, research, and testing. Representing the pinnacle of advanced technology, it stands as the latest product globally to replace traditional grinding mills in the ultra-fine powder processing sector. It has been unanimously recognised as a domestically leading；
It achieves the required fineness (325–3000 mesh) by grinding material (0–15mm) through pressure-applied grinding rollers rolling over a rotating grinding disc.
Its core technical strengths lie in the thorough contact between grinding rollers, grinding disc and material, coupled with the precision grading of its classification system. Under identical feed conditions and product fineness specifications, its output capacity triples that of conventional Raymond mills. At equivalent feed conditions and output requirements, it achieves fineness exceeding 500 mesh beyond that of three-ring medium-speed mills. Under identical feed conditions, fineness, and output demands, its power consumption represents merely 50% of that of air-impact crushers. This machine represents the premier choice for its superior technological sophistication, unrivalled production efficiency, and significant energy savings, surpassing the fineness metrics of wet grinding mills. It is ideally suited for the ultrafine grinding of powdered materials within non-metallic mineral industries, including metallurgy, chemical processing, papermaking, coatings, ceramics, expanded clay aggregate, alumina, and refractory materials.
Working Principle
The motor drives the grinding disc via a reduction gearbox whilst simultaneously engaging with the motor through a belt to drive the hydraulic grinding rollers. Material enters through the feed inlet and falls onto the centre of the grinding disc. Concurrently, hot air enters the mill through the air inlet. Under centrifugal force, the material moves towards the periphery of the grinding disc. As it passes through the annular groove on the disc, it undergoes crushing and shearing to achieve pulverisation. The pulverised material is lifted by high-velocity airflow at the periphery of the grinding disc. Coarse particles fall directly back onto the disc for re-grinding. Material carried by the airflow passes through the classifier, where the rotating rotor causes coarse powder to fall back onto the disc for re-grinding, while qualified fine powder exits the mill with the airflow. This fine powder is collected in the powder collection device, constituting the final product. Moisture-containing material is dried during contact with the hot gas stream, achieving the required product moisture content. During airflow recirculation, minor excess gas along with lighter impurities in the finished product are captured and treated by branch dust collectors within the system. This constitutes a highly scientific and advanced process.
Ultrafine Grinding Mill Production Line Configuration
The SLVTM micro-powder ultrafine grinding system primarily comprises a belt conveyor, bucket elevator, regulating hopper, enclosed quantitative feeder, main unit, hot blast furnace, hydraulic lubrication system, dust collector, finished product silo, fan, and silencer. System configurations vary according to processed materials, site constraints, and client preferences, though fundamental designs remain similar. Systems are primarily categorised as open-circuit or closed-circuit. Open-circuit systems discharge airflow directly into the atmosphere without recirculation, whereas closed-circuit systems enable airflow recirculation, minimising energy loss but requiring more extensive pipework and ancillary equipment.
