Abstract
The utility model relates to a polyurethane wear-resisting drum of a permanent magnet drum-type magnetic cobbing machine, comprising a drum body (1), a centre shaft (2) of the drum body and a permanent magnet (3). The polyurethane wear-resisting drum is characterized in that a polyurethane wear-resisting sleeve (4) is arranged outside the drum body (1). The polyurethane wear-resisting drum of the utility model utilizes the polyurethane elastic body's properties such as corrosion-erosion resistance, high insulating property, hydrolytic stability and chemical medium resistance to employ the polyurethane elastic body as a drum wear-resisting outer sleeve, whose abradability is 3-5 times as that of non-corrodible steel. The polyurethane wear-resisting drum of a permanent magnet drum-type magnetic cobbing machine of the utility model has the characteristics of smooth surface, small friction resistance, light weight, good abradability, non-magnetic body, high electrical resistivity, corrosion prevention, easy replacement and the like, thereby overcoming the existing problems in conventional non-corrodible steel drum, and greatly extending the service life of mineral processing equipments.
Description
Technical field
The utility model relates to the resistant polyurethane rounding tube of permanent-magnet drum type magnetic separator.
Background technology
Existing permanent-magnet drum type magnetic separator is made of cylinder, magnetic system, axis, sorting groove and feed, discharge and overflow machine.The effect of cylinder is to transport the magnetic mineral particle of sorption and prevent that ore pulp from immersing magnetic system, adopts corrosion resistant plate to curl more and is welded, and cost is higher.When ore dressing was worked, cylinder constantly rolled, and directly contact with the ore in sand form friction, and resistance to rolling is big, and abrasion condition is comparatively serious, and after cylinder was worn perforation, ore in sand form starched that promptly to immerse magnetic be that (permanent magnet) causes magnetic separator to re-use and cause equipment scrapping.
Summary of the invention
The purpose of this utility model provides a kind of magnetic separator cylinder of effectively protecting and is not is not worn and torn by ore in sand form, can improve the resistant polyurethane rounding tube of the permanent-magnet drum type magnetic separator in magnetic separator service life.
The technical solution of the utility model is: the resistant polyurethane rounding tube of permanent-magnet drum type magnetic separator comprises the axis and the permanent magnet of cylindrical shell, cylindrical shell, it is characterized in that there is the wear-resisting cover of polyurethane the outside of cylindrical shell.
The utility model utilizes performances such as the resistance to abrasion, high-insulativity, hydrolytic stability, resistant to chemical media of polyurethane elastomer, with it as the wear-resisting overcoat of cylinder, its wearability is stainless 3～5 times, and product has smooth surface, frictional resistance is little, in light weight, wearability is good, characteristics such as non magnetic, high resistivity, corrosion-resistant, easy replacing, thus overcome the existing existing problem of stainless steel cylinder.Improved the service life of preparation equipment greatly.
Description of drawings
Fig. 1 is the resistant polyurethane rounding barrel structure schematic diagram of permanent-magnet drum type magnetic separator of the present utility model.
The specific embodiment
The resistant polyurethane rounding tube of permanent-magnet drum type magnetic separator of the present utility model comprises the axis 2 and the permanent magnet 3 of cylindrical shell 1, cylindrical shell, it is characterized in that there is the wear-resisting cover 4 of polyurethane the outside of cylindrical shell 1.About 2～the 3mm of the wear-resisting sleeve wall thickness of polyurethane is set on the stainless steel cylinder outer surface with specific purpose tool with cover during installation.When ore dressing is worked, directly will contact by the wear-resisting cover of polyurethane, and non magnetic because of the polyaminoacid ester with ore in sand form, can not influence the effect of magnetic separation.When the wear-resisting cover of polyurethane may wear to a certain degree, it is peeled off from cylinder, wear the wear-resisting cover of new polyurethane then again and get final product.
Claims (1)
1, a kind of resistant polyurethane rounding tube of permanent-magnet drum type magnetic separator comprises the axis (2) and the permanent magnet (3) of cylindrical shell (1), cylindrical shell it is characterized in that there is the wear-resisting cover of polyurethane (4) outside of cylindrical shell (1).
