RAWCOOL™ water injection systems we mention is the ones used in the Vertical Roller Mills. Roller mills generally can handle raw materials up to 15% aggregate moisture, and are prone to vibration because of unstable grinding bed.

Vertical Roller Mill (VRM) merupakan salah 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 ditambahkan pada VRM sebagai komponen yang mampu mengurangi vibrasi berlebih yang terjadi.

The first Chinese large-scale Jet Mill MQW160 (gas consumption 160m³/min). There are two types of vertical and horizontal structures to meet the needs of different grinding and classifying requirements.The German technology, automation control design, meet requirements of Industry 4.0.
Vertical Roller Mill often stops due to vibration. One of the causes of vibration is failure of operation on water injection so that water requirement for vertical roller mill is not sufficient. This is because the water supply in the tank is exhausted resulting in the unstable of grinding bed material in the rotary table and overheating of the
elsewhere [2], the use of grinding aids specifically formulated for the use in vertical roller mill allows the reduction in vibration, leading to the following advantages: - possibility of fresh feed increasing and higher mill output; - reduction of water, with consequent decrease of gas temperature and hest needed;

When plotting the pump "all pass" vibration (at the top of the motor) for the various operating speeds, as shown in Figure 2, the vibration is not seen to peak at any distinct speeds (as would be expected with an unbalance or resonance issue), but instead there is much scatter. The only trend is that the vibration generally increases with speed.
1.Mechanical reasons: In the initial design and installation process, the vibration of the vertical mill will be large due to insufficient strength of the basic design and problems in the installation and alignment. If the internal structure of the mill is inconsistent in size, the vertical mill will be inconsistent.
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.
CHRYSO® VRM 159 decreases the need for water injection (up to 50%) through the reduction of mill vibration (~30%). Table vibration is reduced by improving the bed stability and thickness. By lowering the water addition, the cement will have greater mechanical strengths, and reduced setting time.
Ma cement mill (LM 46 2+2), operation without water let to a reduced production. A Loesche Suggestion was to decrease the dam ring height (removal of 6+8) to reduce vibrations and water injection. Experience: After the removal of two dam ring
The differential pressure between the inlet and outlet of the mill (ΔP mill) is an important process variable for the testing of grinding aids.ΔP mill reflects the load and the filling level of the mill. At unchanged separator settings, the increase of ΔP mill indicates more internal circulations and more fines. As a result of the higher ΔP mill, the mill vibration increases (8-10mm/s ...

Water injection tests. The impact of water injection is explained below. In general water injected on the mill table acts as a grinding aid to increase production and lower power consumption. Water also helps reduce mill vibrations, especially with dusty clinker.
