The first to identify the equipment, installation position and material type of impact or wear method is a choice for candidate materials. Parts with similar names may be used in completely different types as they are granularity (material), shock energy; temperature: corrosion - structural dimensions).
For crushing, grinding and transmission parts hardness is only an indicator; impact toughness quenchability of the shocks to be determined by their refractive properties as well in terms between size dimensions.
Low impact, fineness sliding wear Regions may not be adequate Work Hardening.
View high-manganese steel and parts Relatively -chromium molybdenum steel, Martensitic Steel and ordinary Construction Steel is not the same materials. must be struck and cut operating conditions Differences.
View alloy steel Application boundaries -Large blocks of direct impact, metal aliens and clearly curved load positions need to be used with caution.
View high-chromium cast iron Apps -Power Transmission First, the stubbornly untouchable and not only in name Hardness Or " Wear-Resistant Steel "Replacement of name.
View Power Transmission s materials and parts Relatively -thickness, welding heat inputs and curved radius as well cryogenic impact performance must be combined with Construction Co-educational Config.
View wear-resistant steel plate Apps -The shaft neck, gaps and lubrication of the load must be matched with pollution control.
View Bearing and Copper Alloy Materials →Put extremely high hardness materials in the real wear zone, leaving toughness substrates to carry area; interface and fixation methods are often more important than individual hardcore values.
Not suitable as a whole to withstand the big deformation Construction Pieces; Pillar Pines Geometry, inlay and welding Quality It's key.
View cemented carbide With Composite Applications -No buffer ceramic Not suitable for a large block of direct impact; must be clear ceramic Types, purity and fixed mode of the base.
View ceramic Compound Applications“ Composite Materials "It is not a brand name; interface combination, hard-phase position and impact boundary determine reliability.
View Dual Metals Construction →Control of the base body solderability, dilution rate and interlayer temperature. Fractals & residual stresses are required
View Hardfacing and Repair →It must be made of temperature, medium and stress. Manufacturing The process is jointly selected, and can not be used with "heat-resistant steel" Stainless Steel "The name is substitute.
View Specialty materials Borders -This group materials Cannot be generally called "plastic" or rubber "Frequency, impact and sludge temperature; medium: perturbation - fixing mode determine whether it can be used for specific purposes parts.
Needs to differentiate rubber Liners, PU wear parts and sealing elastomers; temperature, hydrolysis is different from the teared boundary.
View Rubber and Polyurethane Apps -Temperatures, creeping and porous stresses must be verified as well; molecular weight of the formulae service life Cannot be materials The name presumption.
View materials, parts and Item Borders -NBR, HNBR, FKM, PU and PTFE The temperature and the media boundary are different, can not be interchanged in general.
View Seal Materials and parts Relatively -This is a pre-screening table, not in place of the final Material Selection The final plan is back Equipment Models, drawing number Scales, Materials and Photographs of Failed Parts.

Reciprocity Equipment and parts: FLSmidth HPGR PM9-24/19M Feed/feeding polymer Liners Graphics belong M З- 0621 Series, Manufacturing The thickness of the finished paper is 60 mm.
Why choose this type materials: The location is also sludge shock, sliding wear and the risk of gluing, Material Options Need to balance low friction, lower water absorption and shock resistance with wear-resistant properties.
Borders that must be retained: Molecular volume and formulation belong to Item Requests, on site service life belonging Item Feedback; the customer's proposal 24 Months are not a single requirement that the website can directly commit service life.
