Superfine powder Raymond mill is commonly used in mineral processing equipment of mineral processing plant, but also the high energy consumption equipment, design and parameter optimization of energy-saving design of
Raymond mill , to reduce the energy consumption of mineral processing, has important significance in improving the efficiency of processing.
1. energy saving design of superfine Raymond Mill
The superfine Raymond mill mainly considers energy saving design from aspects of starting mode, lubrication mode, bearing type, lining plate structure and form, and speed ratio of Raymond mill. Raymond mill is manufactured by national industrial technology group. It has many characteristics in energy saving design, and the equipment must be operated according to the design requirements.
(1) startup mode design
Soft start pneumatic clutch. Realize the synchronous motor - Raymond mill segment start, and can make the motor no-load start, to achieve stable operation speed, and then the clutch combination, start Raymond mill. In this way, the starting time of the motor itself is shortened, the start-up is easy, the impact of the starting current on the power grid is reduced, and the installed power of the Raymond mill is reduced.
2. hydrostatic bearing and static and dynamic pressure bearing design
It is the common design of superfine Raymond mill by dynamic and static pressure mixed lubrication bearings instead of ordinary bearings.
(1) in the Raymond mill before starting, high pressure using lubricating oil will float the shaft neck of 0.2 ~ 0.3mm, it can greatly reduce the starting load, and then start, after which can make the shaft and bearing by external supply, with certain pressure bearing oil film is completely separated from the start, when the shaft neck reach enough speed, namely the use of hydrodynamic lubrication bearing.
(2) when the Raymond mill is stopped, let the pressure oil float the axle neck slowly onto the Bush, so as not to abrade the bush. This ensures that the journal is started under pure liquid friction. The friction resistance is small, the power consumption is small, and the transmission efficiency is high.
