Abstract
The utility model discloses a grinding roller for an intermediate-speed mill, and belongs to mineral material grinding equipment. The grinding roller is formed by arranging an abrasion-resistant alloy layer on the peripheral outer surface of a carbon steel ring of which the cross section has a shape of a convex cambered surface in a covered mode. The grinding roller has a simple structure, long service life and a simple and practicable repairing process, can be repeatedly repaired and is low in using cost.
Description
Technical field
The utility model belongs to the mineral materials milling equipment, relates generally to a kind of machinery that material grindings such as ore, lime stone, coal are handled.
Background technology
In enterprises such as thermal power plant, steel plant, cement plant, mine, the medium-speed pulverizer that is widely used is accomplished the grinding operation of various materials such as coal, ore, lime stone.Grinding roller is an operation part main on the medium-speed pulverizer.At present, grinding roller all is to adopt technique for integral casting to process by a kind of metal material, not only casts the cost height; Product is prone to produce casting flaw during casting, be prone in the use fracture defect takes place, and grinding roller operation surface hardness is not high; Easy to wear; And repair difficulty, the renovation technique conditional request is harsh, has strengthened the material grinding operating cost.
Summary of the invention
The purpose of the utility model is exactly the problem that exists to above-mentioned prior art, and design provides a kind of medium-speed pulverizer grinding roller of new construction, reaches the purpose that improves the grinding roller abrasion resistance, increases the service life, reduces manufacturing and operation use cost.
The basic design of the utility model is, is at cross section to cover on the carbon steel steel ring circumferential outer surface of evagination arc surfaced wear-resistant alloy layer is set, and constitutes the medium-speed pulverizer grinding roller.
On the carbon steel steel ring circumferential outer surface that the carbon steel plate weldering system that it is good that the utility model is employed in intensity, plasticity forms the wear-resistant alloy layer structure is set; Realized the purpose requirement that improves the grinding roller abrasion resistance, increase the service life, reduce manufacturing and operation use cost, the characteristics of have simple in structure, long service life, can repair repeatedly, renovation technique is simple, use cost is cheap.
Description of drawings
Fig. 1 is a medium-speed pulverizer grinding roller structural front view;
Fig. 2 is an A-A profile among Fig. 1.
Piece number explanation among the figure:
1, carbon steel steel ring, 2, wear-resistant alloy layer.
The specific embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.A kind of medium-speed pulverizer grinding roller is at cross section to cover on carbon steel steel ring 1 circumferential outer surface of evagination arc surfaced wear-resistant alloy layer 2 is set.Described wear-resistant alloy layer 2 can select the wear resistant alloy material of different components, different hardness to adopt the bead-welding technology technology that it is fitted on carbon steel steel ring 1 circumferential outer surface admittedly according to the difference of grinding material and operation operating mode.But built-up welding reparation after the wearing and tearing.
Claims (1)
1. medium-speed pulverizer grinding roller is characterized in that on cross section is carbon steel steel ring (1) circumferential outer surface of evagination arc surfaced, covering configuration wear-resistant alloy layer (2).
