Technical field
The present invention relates to a kind of three taper wear-resisting centrifugal machine rotary drums, belong to mine equipment technology field.
Background technique
Currently, the horizontal thin stream film centrifuge of SLon is widely used in the black such as depth cleaning iron oxide ore, tungsten, tin, tantalum niobium
And rare metal ore, have many advantages, such as concentration ratio height, energy conservation and environmental protection, has a extensive future.The most crucial component of this kind of centrifuge
For rotary drum, it is a kind of pyramidal structure body along ore pulp axial flow direction there are certain cone angle, and it is empty that inner surface constitutes separation
Between.The grading principle of this kind of centrifuge is to transit to the selectivity centrifugation in the thin stream film of laminar flow state in weak turbulent flow based on ore particle
Sedimentation, the flow stability for flowing film has decisive influence to mineral separation, to influence the performance of centrifuge equipment.Turn
Bulging cone angle structure determines the flowing acceleration and speed of thin stream film, and surface roughness is then to the stability for maintaining stream membrane flow
It plays a crucial role.Therefore, rotary drum cone angle structure must be suitable, and surface roughness must maintain a long-term stability, and is likely to ensure to give birth to
Index is produced to stablize effectively.
For a long time, people are by rolling steel plate, then processing and fabricating rotary drum.But since hardness of mineral is big, using certain
After time, wearing in various degree easily occurs in rotary drum inner surface, so that surface smoothness and roughness is changed, this will change ore pulp
The fluidised form and its stability of thin stream film, final reduce even deteriorate Separation Indexes.In addition, people are using single cone or double so far
Tapered configuration rotary drum causes flow of slurry film to accelerate flowing quickly in rotary drum inner surface, the axial flow velocity U of suitable minerals separation1→U2
Apart from short (see Fig. 2)；This velocity flow profile is unfavorable for table in rotary drum on the one hand since rotary drum separating distance and sorting time are short
Face separation and deposition enrichment (micro-) fine-grained heavy minerals, two aspects cannot farthest utilize the (separation of bowl inner surface
Space), i.e. working face utilization efficiency is low, causes the processing capacity of centrifuge low.
