High-pressure roller mill is a vertical mill, on the basis of vertical mill, improved the pressure of the roller device, the use of hydraulic system instead of the original mechanical pressure system. Hydraulic system to ensure the stability of the pressure and durability, the result is a more uniform degree of material grinding to ensure that ...
the roller speed has 3 times faster than common three roller mill. Three rollers has individual cooling system, also equips inlet water thermometer and outlet water thermometer to check the temperature's variation, according to the temperature's variation to control the flowing water and keeping the rolling temperature in suitable situation.
Hydraulic Three Roll Mill, which is a full hydraulic auto-controlling system equipment. 1- Cooling system: an individual cooling system for each roller. 2- hydraulic control: hydraulic control pressure blades, roller gaps, etc. 3- Optional installation:PLC system with SIEMENS touching screen, FRANLI engineer set formulas of grinding according ...
Compressive stresses produces crushing action on the clinker. Friction causes Roller and Table to rotate synchronously generating shearing stresses. Shearing stresses produces grinding action on the clinker. A grinding force is transmitted to a set of three rollers at 120 Degree apart through a hydraulic system.
Hydraulic oil plays a role of transmitting pressure, lubricating, cooling and sealing in hydraulic system. Improper selection of hydraulic oil is the main reason for early failure and durability deterioration of hydraulic system. ...

This roller press can improve the grinding capacity by 50 ...
The grinding rollers are raised hydraulically from the grinding table prior to commencing grinding. This is realised by reversing the oil pressure exerted on the spring assembly cylinders. The grinding mill can therefore be started in an empty or full state with a low starting torque (approx. 40% of the nominal torque).
