Abstract
The utility model relates to a magnetic lining plate for an ore mill. A magnetic system is composed of unit magnets whose polarities are arranged at intervals. Each unit magnet is arranged in a box-shaped protective cover, and the protective cover and the magnets are fixed in a magnetic guidance plate via a screw rod. Filling materials are arranged between the protective cover and the magnets. The magnetic guidance plate is fixed on the inner wall of the cylinder body of the ore mill via a screw rod welded on the lower surface of the magnetic guidance plate. The magnetic lining plate for an ore mill has the advantages that the lining plate can be overhauled, the service life can be largely extended, etc.
Description
The utility model belongs to the annex of ore mill.
Grinding mill liner is one of main consumable part of ore mill.Mostly existing ore mill cylindrical shell interior lining panel material is potassium steel, seldom is rubber.After high manganese steel lining plate and rubber lining use a period of time, wearing and tearing are very fast, need often to change.In order to improve the service life of liner plate, actively developing magnetic liner plate both at home and abroad.Rubber-magnetic liner plate and metal-magnetic liner plate are arranged.Rubber-magnetic liner plate is under test mostly, and domestic some ore dressing plant of metal-magnetic liner plate is brought into use.Existing metal-magnetic liner plate is that magnetic material is contained in the metal coating shell, by binding agent magnetic material and metal coating shell is bonded together, and constitutes an integral body and uses as liner plate.This liner plate exists a problem can not overhaul exactly, the long-term use, and the metal coating shell will be worn away by steel ball, and magnetic material will demagnetize, magnetic field intensity will significantly reduce, the effect of the liner plate that loses magnetism.In addition, because this liner plate leans on the magnetic force sorption on the ore mill cylinder inboard wall, in the ore mill running in a single day the liner plate local shedding takes place, then whole liner plate just might large tracts of land come off, and consequence is serious.
It is a kind of in light weight that the purpose of this utility model is to provide, extremely wear-resisting, easily changes, and the magnetic that can overhaul is liner plate.
Magnetic of the present utility model is that liner plate is made of five parts such as permanent magnet magnetic system, box-shaped protective cover, screw rod, magnetic conductance plate and fillers.Describe content of the present utility model in detail below in conjunction with accompanying drawing.
Accompanying drawing is a structural representation of the present utility model.
Fig. 1: [1]-magnet; [2]-the box-shaped protective cover; [3]-the magnetic conductance plate; [4]-cylindrical shell; [5]-filler; [6]-screw rod.
Magnetic system is made up of some polarity unit magnet [1] alternately. Top in each magnet [1] Box-shaped protective cover [2] is housed, and this protective cover [2] is to make with the nonmagnetic steel of wear-resisting erosion, in protective cover [2] And filler [5], its effect are arranged between the unit magnet [1] is to prevent from being subjected to the steel ball blastic deformation because of protective cover And make magnet cracked. At protective cover [2] and porose above the magnet [1], will be with protection by screw rod [6] The magnet of cover is fixed on the magnetic conductance plate [3], and namely having consisted of magnetic of the present utility model is liner plate. The magnetic conductance plate [3] select the higher material of the good permeability of corrosion resisting property, make magnetic resistance minimizing in the magnetic circuit, be conducive to Improve the magnetic field intensity of magnet surface. Be welded with metal screw [7] below the magnetic conductance plate [3], pass through spiral shell The hole that bar [7] is connected with the ore mill barrel connects, and is that liner plate is fixed in the ore mill cylindrical shell [4] with whole magnetic On the wall. In order to make liner plate fix more firmly, make the vertical plane of box-shaped protective cover [2] both sides protruding Recessed biting connecions, mutually interlock conditions each other between each box-shaped protective cover. For prolonging the box-shaped protection In the life-span of cover [2], box-shaped protective cover end face of the present utility model has convex tendon, during use, protects in box-shaped Store some magnetic mineral fines that broken steel ball, iron filings and accumulation are arranged between the convex tendon of guard shield [2], consisted of To the protective layer of protective cover, play important protective effect, thereby the life-span of liner plate is prolonged greatly Long.
Using magnetic of the present utility model is liner plate, when has gone bad certain of liner plate, or need all overhaul The time, the ore mill that can stop unloads bad partly or entirely, changes one group or several groups of new unit Magnet or whole unit magnet, liner plate can continue to use. Thereby greatly improved the utilization of liner plate Rate has reduced a large amount of material consumptions.
The utility model can also prolong 6～15 times of liner plate life-spans, reduce ball consumption about 10% except that having the characteristics that can overhaul, also has saves energy simultaneously, increases the ore mill dischargeable capacity and alleviates multiple advantage such as labor strength.
Claims (3)
- One kind include magnet, protective cover is a liner plate at interior magnetic, it is characterized in that liner plate constitutes magnetic system by some polarity unit magnet alternately, each is covered with protective cover above the unit magnet.By screw rod protective cover and magnet are fixed on the magnetic conductance plate together, the magnetic conductance plate is fixed on the cylinder inboard wall of ore mill again, between protective cover and magnet filler is arranged.
- 2. magnetic as claimed in claim 1 is liner plate, it is characterized in that said protective cover is the box-shaped protective cover, and its both sides vertical plane is made the convex-concave biting connecions, and the protective cover end face has convex tendon.
