gyratory crusher parts | wear parts for industry | qiming casting

The Qiming Casting primary gyratory crusher parts have the most important role in rock size reduction in mine operations as the crushing process starts from a primary crusher. The highest possible wear life is combined with mechanical reliability through the component life cycle. As the production stops are very expensive for mine operations, the Qiming Casting manganese gyratory crusher wears are easy and quick to install.

Manganese steel mantle wear parts are provided with different shapes, surface profiles, and steel grades. Alloy steel, TIC inserts, and manganese steel concave wear parts are designed for the hardest rock in surface and underground operations.

Our many mantle designs range from smooth one-piece options to large, full-toothed, two-piece, or three-piece solutions. Teeth can be used at almost any level on mantles to improve nip. Our users report that teeth greatly reduce slippage, and improve both production and liner wear life.

For example, crushing some tough materials demands work-hardening manganese steel. But the same liners used for an abrasive, friable ore may wear quickly because there are insufficient impacts to cause the surface to work harden.

Agyratory crusherincludes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when thecrushingsurfaces approach each other and the crushed products fall through the discharging opening.

The gyratory crusher is composed of transmission, frame, eccentric sleeve, mantle, concave segments, middle frame, beam, prime mover, oil cylinder, hydraulic pressure, pulley, electrical and dry, thin oil lubrication, and other parts. The motor drives the eccentric sleeve to rotate through the belt pulley and the bevel gear, and when the eccentric sleeve rotates, it drives the crushing cone to swing around the center of the crusher. As a result, the surface of the crushing cone is sometimes close to and away from the surface of the fixed cone, so that the materials fed into the crushing cavity are continuously squeezed and bent, and crushed. The crushed material is discharged from the bottom of the crushing cavity by its own weight.

The advantage is that the crushing process is continuously carried out along the circular crushing cavity, so the productivity is high and the power consumption is low, which works smoothly and suitable for crushing flake materials. It can be seen from the particle size distribution curve of the finished product. In the particle size composition of the finished product, the particle size of the material exceeding the width of the discharge port is smaller than that of the jaw crusher, the quantity is also less, and the particle size is relatively uniform. In addition, the raw materials can be poured directly into the feed port from the transportation tool without the need to set up a feeder.

The disadvantages: Complex structure. The price is higher; the maintenance is more difficult, and the repair cost is high; the higher the fuselage increases the cost of the plant, foundation, and other structures.

The gyratory crusher mantle is the major wear part of the gyratory crusher. The mantle which is the movable working surface is pivoted at its top within a spider bearing under the cap of the spider arm assembly while the bottom is gyrated within an eccentric bushing which is powered by the drive assembly.

A mantle for a gyratory crusher having a generally truncated conical shape and having a lower portion that is subjected to greater crushing stress than the upper portion. The upper surface portion has at least one groove which is concentric with the axis of the mantle. During crushing operations, the mantle will grow due to the stresses applied during crushing. This growth will normally result in a bulging of the mantle. The groove in the mantle will permit the mantle to grow thereby reducing bulging. If the mantle is made of two pieces, the groove may be located at the junction of the two pieces.

Different crushed materials need to choose the right material to cast the gyratory mantle. The first choice of material for standard mantles is the Mn14. To further maximize performance and wear life, special designs and high-alloy options are also available.

Standard gyratory crusher concave alloy is manganese, but depending on the feed characteristics a variety of other alloys can be chosen to achieve the best cost per produced ton. The upper concave tiers must withstand high impact forces. The lower tiers require maximum abrasion resistance.

The fewer concave segments you have to handle, the less time it takes to reline your gyratory. We recognize the value of fewer and larger concave segments, and weve manufactured double-height, double-width, and double-height & width concaves for many satisfied customers.

The benefit to you is greater efficiency when ordering and replacing parts. In general, larger parts cost less per pound. There are also fewer seams, an important consideration since these are often the areas of most severe wear. In addition, fewer joints mean less backing material.

General-purpose concaves with uniform thickness often wear poorly because the wear is not uniform from application to application. We have found that by increasing thickness, we can often double or triple wear life. All our concaves have side grooves for spacer or keeper dowels.

modelling and simulation of ball mill wear - sciencedirect

In the mineral processing industry, ball mills are used to reduce ore from one size distribution to another. Ball mill wear occurs as a result of the violent interactions within the ball charge. In the present article, a mathematical description of wear has been added to a ball charge motion model. Wear is associated with the comminution mechanisms found in the ball charge profile. It is assumed that ball mill wear occurs in each of three comminution zones, with adhesive wear found in the crushing and tumbling zones and abrasive wear arising in the grinding zone. Wear rates are proportional to the energy dissipated in these zones as predicted by the charge motion model. Three laboratory case studies are investigated followed by one full-scale example in a wet milling context. Simulation results are compared with experimental data from which real-system predictions are presented. The use of these results provides the possibility of optimizing ball mill performance while including the wear rate factor.

The structure of the ball mill gear wheel has different shapes due to different requirements, but from the perspective of the process, the wheel can be regarded as consisting of two parts: the ring gear and the wheel body. According to the distribution form of teeth on the ring gear, it can be divided into straight teeth, helical teeth, herringbone teeth and so on.

In the semi-finishing process, the gears are basically formed, after which they are processed to obtain the mechanical properties of the gears. According to the requirements of the working conditions and the materials used ,the quenching and tempering, the carburizing quenching, and the tooth surface high-frequency induction are used. Heat quenching, nitriding and other processes make it possible to obtain the mechanical properties that should be obtained under different working conditions.

For large diameter (D> 400-600mm) tooth blanks can not be forged, cast steel tooth blanks can be used, generally used ZG45, ZG 40Cr, ZG 42CrMo, ZG 40CrNiMo, ZG 38CrMoAl and other medium carbon alloy steel. The steel composition of the cast steel is equivalent to the chemical composition of the forged steel and only increases the Si content to 0.60-0.80%.

tips for buying crusher wear liners

Crusher wear liner replacementis probably one of the mostimportant areas and decisions herecan have a significant influence on the costper tonne produced. When decision timecomes to buy replacement manganese steelwear liners for your plant, it is importantto choose the right crusher wear liner manufacuturer. To ensure you will be getting thebest liner profile option for your plant,and a quality product that will performwithout premature failure or damage toyour crusher, the quarry manager shouldconsider the following points and ask therelevant questions:

There are hundreds of crusher liners casting foundries in the world. Most of foundries located in developing countries. Because cast foundry will bring large number of enviroment problems , on the other hand, casting industry are also need care about the cost. Qiming Casting located in the west of China,whichcovers an area of 40 acres, a total investment of 70 million yuan. It specializes in the production, sales and research of wear-resistant, high temperature-resistant, corrosion-resistant materials with the annual production capacity of over 15,000 tons.

Manganese steel was invented by SirRobert Hadfield in 1882 and was uniquein that it combined high toughness andductility with exceptional work-hardeningcapacity. The material developed forcrusher wear liners contained aroundone per cent carbon (C), 11 per centmanganese (Mn) and the balance iron(Fe). This material was cast followed byheat treatment after initial cooling. The heat treatment process included heatingto above 10000C, to convert the brittleas-cast multi-phase microstructure to asingle phase austenite, followed by a rapidwater quench. The single phase austeniticmicrostructure remains stable at roomtemperature, producing a ductile highstrength material resistant to the fatiguesubjected by the rock crushing process.The material can readily revert back to thebrittle as-cast structure in weld areas orduring other thermal processes and careshould be taken to avoid this. The standardHadfield austenitic manganese steeldescribed in Australian Standard AS2074Grade H1A remains the most reliablematerial for crusher wear liners. Thematerial has a starting Brinell hardness ofaround 200 and the ability for the workingsurface to harden to above 500. With Cabove one per cent and Mn above 11 percent, it is considered the best material forthe crushing of high compressive strengthrock. Increasing the carbon and manganeselevel does change material properties thatcan improve the wear life when crushinglower compressive strength rock, althoughthe reduction in the liner fatigueresistance must be considered.
