Sandreck’s MW Ultrafine Grinding Machine embodies more than 30 years of production experience and integrates the advantages of domestic and foreign Mill manufacturers. It provides you with a new type of efficient and reliable Ultrafine powder processing equipment to help you easily cope with production challenges.
Company Advantage
The Ultra-Fine Grinding Mill manufactured by Sandreck is a grinding mill that utilizes the rolling, impacting, and grinding effects of multi-layered ring rollers.
Quantified feeding and initial stage separation
The feedstock is placed into a grinding chamber and dispersed by centrifugal force.
Lake of multi-layered cyclical comminution
The material progressively falls in order from layer to layer (usually four) of grind rings and rollers and is pressed, rolled, and ground continuously while not losing the ability to pulverize.
Air conveyance and separation
The ground material is drawn into the classifier by negative pressure air flow from the induced draft fan. Coarser particles are separated from the air stream and fall back into the grinding chamber to be re-ground.
Product collection
The fine powder is directed out and to a cyclone / bag dust collector and the finished product is discharged through the valve. The remaining purified air is exhausted out through fans and silencers.
MV Ultra-Fine Grinding Mill Parts
Sandreck’s MW Ultrafine Grinding Mill are equipped with tungsten carbide grinding rollers and rings (hardness HRC65+) with precisely matched rings resulting in a wear life of greater than 12,000 hours and a 30% reduction in the frequency of part replacement.
The MW Ultrafine Grinding Mill comes with a variable frequency intelligent classifier so you can adjust the fineness of the ring roller mill with a single touch from 80-400 mesh. The finished product D97 deviation is ≤1% and the pass rate is greater than 99.5% thus eliminating the chance of dismissal due to unstable fineness.
Using a high-efficiency pulse dust collector with a dust collection rate of ≥99.9% during production throughout the entire process Sandreck’s ring roller mills are dust-free and easily comply with the environmental requirements while also recovering fines according to the environmental requirements.
Sandreck’s MW Ultrafine Grinding Mill have a variable frequency motor with a precision reducer allowing flexible speed adjustment according to material hardness, leading to greater than 10% energy savings, reducing overloads and stalling, and operate the entire production line continuously.
