A hydraulic accumulator is a pressure storage reservoir in which a non-compressible hydraulic fluid is held under pressure that is applied by an external source of mechanical energy. The external source can be an engine, a spring, a raised weight, or a compressed gas.
Raw mill is mainly used in grinding raw materials and end products in cement plant. It is also suitable for various ores and other materials metallurgy, mine, chemical and construction. Besides, it has two forms of milling, one is an open form, and the other is a recycle close form equipped with powder concentrator.
accumulators, the cylindrical jacket is filled with nitrogen gas (pressure 1,15 bar at room temperature). After installation the piston accumulator can be filled with a wide range of mineral oils, depending on the application. Other types of hydraulic fluids are optional.
