How the Ultra-Fine Grinding Mill Works?
The ultra-fine grinding mill manufactured by Sandreck achieves pulverization through the rolling, impact, and grinding actions of multi-layer annular rollers.
Quantitative Feeding and Primary Separation
Material enters the grinding chamber and is dispersed by centrifugal force.
Multi-layer Cyclic Pulverization
Material passes sequentially through four layers of grinding rings and rollers. It undergoes continuous compression, rolling, and grinding, maintaining a state of ongoing pulverization.
Airflow Conveying and Classification
Ground material is transported to the classifier by a negative-pressure airflow generated by the draft fan. Coarser particles are separated from the airflow and fall back into the grinding chamber for regrinding.
Finished Product Collection
Fine powder is conveyed to a cyclone separator or bag filter, and the finished product is discharged through a valve. The remaining purified air is exhausted via the fan and silencer.
MV Ultra-Fine Grinding Mill Parts
Our MW ultrafine grinding mill is equipped with tungsten carbide grinding rollers and rings featuring a hardness exceeding HRC65. Thanks to a precision-matched component design, the wear life exceeds 12,000 hours, reducing the frequency of component replacement by 30%.
The MW ultrafine grinding mill is equipped with an intelligent variable-frequency classifier, allowing the grinding fineness to be adjusted within the 80–400 mesh range via a simple one-touch operation. The finished product achieves a D97 deviation of ≤1% and a screening pass rate exceeding 99.5%, effectively eliminating the risk of product rejection due to inconsistent fineness.
Throughout the production process, the Sandreck ring-roller mill uses a high-efficiency pulse dust collector with a dust removal efficiency of 99.9% or higher, ensuring dust-free operation. This not only easily meets environmental protection requirements but also enables the recovery of fine powder in accordance with regulations.
The Sandreck MW ultrafine grinding mill is equipped with a variable-frequency motor and a precision gearbox. The rotational speed can be flexibly adjusted based on the material’s hardness, resulting in energy savings of over 10%. This setup reduces the risk of overloads and downtime, ensuring the continuous and stable operation of the entire production line.
