Vertical roller mills are large grinding machines developed, designed and manufactured by Sinoma-tec; Sinoma-tec vertical mills feature a rational and reliable structure as well as an advanced process that combines drying, grinding, separation and conveying, which is .

Lumps and blockages in cement silos have long been an issue at some cement plants. In the 1970s, FL conducted research on ball mills and cement storage that revealed the cause to be an unfortunate combination of insufficient gypsum dehydration in the mill, high silo storage temperature and lengthy storage time.

Vertical Roller Mill (VRM) merupakan sal satu equipment penting yang digunakan oleh PT. Holcim Tuban Plant Indonesia untuk kegiatan grinding material. Vibrasi berlebih yang ditimbulkan oleh VRM menyebabkan operasi VRM harus diberhentikan. Water injection ditambkan pada VRM sebagai komponen yang mampu mengurangi vibrasi berlebih yang terjadi.

The production of Portland Cement (OPC, CEM I) with Vertical Roller Mills can demand the following benefits from a Grinding Aid: ́ Increased production rate, energy saving ́ Higher fineness, faster strength development ́ Reduced vibration, less wear ́ Reduced water injection, less pre-hydration

Royal machine mounts simplify machine installation, reduce noise, and isolate vibration. They are great for all types of machinery, including lathes, mills, grinders, presses, and injection molding machines. Royal machine mounts meet OSHA requirements by preventing machines from "walking" without the need for bolting or cementing.
