Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a flow stabilizing device for roller presses. Background Art

[0002] Roller press is a common crushing equipment, also known as roller crusher or roller crusher. Roller press usually consists of one or more pairs of parallel rotating rollers, with gaps between the rollers. Materials are squeezed and crushed through the gaps. Roller press is suitable for materials of various hardness and humidity. It can crush block materials into required granular or powdery materials. In the cement production process, the supporting volume of the roller press with specifications of 150*100 is 30m 3 During production, the material is homogenized and stabilized in the stabilizing bin and then squeezed and crushed by the roller press.

[0003] In the cement production process, due to the material deviation phenomenon when feeding the steady flow bin, the material impacts the polyester anti-skid plate in the bin when falling, causing serious wear of the anti-skid plate; the material deviation phenomenon leads to uneven distribution of large and small particles in the bin and cannot form dense materials. This phenomenon repeats over and over again, and eventually causes excessive powder in the bin to separate, resulting in material collapse and leakage in the steady flow bin, large changes in the roller gap, abnormal current fluctuations, and frequent pressurization of the hydraulic system, resulting in the material squeezed by the roller press not being able to form a dense cake, making the grinding fineness coarse and the specific surface area low, and failing to achieve the effect of more crushing and less grinding, affecting energy consumption control.
