1. Coarse grinding bin liner plate leh wear-resistant material thlan dan tur wear mechanism
Coarse grinding bin abrasive℃chu 15mm-25mm a ni a, grinding body-a spherical diameter average chu Φ 75mm a ni a, spherical diameter sang ber chu φ 90mm-l oomm a ni. Mill a inher chuan ball leh material chuan lining plate chu impact force lian takin a cut a; Ball squeethe material chu falling sliding emaw rolling emaw a ni a, chuvangin rough grinding liner-a wear mechanism chu high stress impact cutting wear atanga siam a ni ber a, extrusion cutting hmanga tihpun a ni.
Crude grinding bin lining plate mamawhna Material hian toughness a nei tling a, cutting wear requirements material chu hardness sang tak nen a nei a ni. Wear principle ang chuan material hardness (HM) chu material hardness (HA) aiin a let 0.8 aia tam a ni tur a ni (HA), chu chu HM / Ha 0.8 a ni a, cement clinker hardness chu HV 500-550 a ni a, HRC 49-54 nen a inang a ni. Chuvangin, lining plate material hardness chu HRC 50 aia sang a ni tur a ni a, stress impact chisel sang tak avang hian impact toughness AK 10J / CM2 hian a crack thei lo, hman tur a tlin theih nan. Chuvangin, coarse grinding bin lining plate chu medium carbon chromium alloy steel leh a ang chi alloy steel material, hardness HRC 48-55, impact toughness AKL 5-20J / cm2, service life kum 2-3 thleng thlan tur a ni. Single screw hole liner leh groove liner atan chuan high chromium cast iron thlang la, a kaihhnawih tehfung angin, service life chu kum 4-6 a tling thei ang. Φ 3M aia sang mill liner lian tak tak tan chuan high toughness high chromium cast iron, hardness HRC 58-62, impact toughness AK8-12J / cm2, service life kum 6-10 thleng thlan tur a ni.
2. Wear Mechanism of fine grinding village board leh wear-resistant material thlan chhuah
Partition board kaltlanga fine grinding bin chhunga lut material chu a hring deuh a, sharp angle chu a blunt ta a ni. Fine grinding bin-a ball emaw segment emaw diameter chu Φ 15mm-60mm chauh a ni a, impact force chu a tlem a, chuvangin thin grinding bin liner-a wear mechanism chu ball-a stress cutting wear a ni.
Fine grinding bin lining plate can choose high hardness, low toughness of wear-resistant materials. Such as high carbon alloy steel, high, medium and low chromium cast iron, anti-wear ductile cast iron and other materials, hardness HRC>50, Impact Toughness AK4-6J / CM2 hman theih a ni.
Mill lining plate hian high manganese steel a thlang tur a ni lo. Coarse grinding warehouse tan chuan, high manganese steel yield strength a hniam avangin plastic deformation siam a awlsam a, lining plate lian tak chu convex deformation a awm ang a, steel ball-a nghawng chu processing hardening a siam kim thei lo va, chuvangin wear-resistant a ni lo. Fine grinding bin lining plate-a impact force chu a tlem zawk a, high manganese steel-a wear resistance pawh a play theih loh.
3. Grinding head end lining plate, compartment plate leh branch grate plate grinding atana hman tur wear-resistant material thlan chhuah
(1) Grinding head end liner plate leh wear-resistant material thlan dan tur wear mechanism
Grinding head-a village board chu coarse grinding bin feeding end-ah a awm a, grinding body-a particle size average chu a lian hle a, grinding ball leh material-a side impact a lian a, chu chu wear mechanism a ni a, stress impact cutting wear leh supplemented by cutting erosion a ni. Chuvangin, grinding head end lining plate chuan toughness sang tak leh impact resistance, hardness sang leh cutting resistance nei materials te chu a thlang tur a ni. High manganese steel hman hma hian, a processing hardening chu a taka siam theih turin a nghawng a tawk lo a, hardness chuan Hb 350 vel chauh a thleng thei a, chu chu material cutting erosion wear hmangin a na hle a, service life pawh a hniam hle. Medium carbon multiple alloy steel lining plate, Hardness HRC 46-50, Impact Toughness AK5 J / CM2 i thlang a nih chuan service life hi high manganese steel aiin a let hnih in a sang thei a ni.Φ
