Mining Industry
Since 1992, ZHILI has supplied jaw plates, blow bars, and impact plates to mining and quarrying operations across Southeast Asia, the Middle East, Africa, and South America. Our CrC overlay jaw plates have been installed in granite crushing lines processing feed sizes up to 800 mm, with operating records exceeding 3,000 operating hours per set before first replacement.
For high-silica ore (SiO2 content above 65%), we recommend CrC overlay jaw plates with a surface hardness of HRC 60-65, built on a Mn13Cr2 base plate for impact toughness. Overlay layer thickness ranges from 8 mm to 15 mm depending on abrasion severity. For impact crushers processing iron ore at rotor tip speeds of 35-45 m/s, our high-chrome white iron blow bars (Cr26-Cr27 grade, ASTM A532) deliver consistent performance without spalling or premature breakage. Standard jaw plate dimensions: 250×400 mm to 1200×1500 mm. Custom non-standard sizes available from drawings or worn samples.
ISO 9001:2015 certified (GICG UK). Authorized SSAB Hardox Wear Parts Center (APC-17-29). National invention patent ZL 2016 1 0056588.5 in wear-resistant casting technology. Exported to 30+ countries. Clients include Holcim Argentina, CEMEX Mexico, and E.Bayer Germany.
Standard warranty: 90 days from delivery date. Material test reports (MTR), ultrasonic inspection records, and Rockwell hardness certificates included with every shipment. Full traceability — every crate labeled with customer name, product description, and quantity.
Cement Industry
ZHILI has served cement plants in India, Vietnam, Indonesia, Egypt, and Pakistan for over 20 years. Our heat-resistant castings operate in rotary kiln nose ring zones with shell temperatures exceeding 900°C, and pre-heater tertiary air ducts reaching 1,100°C. Grinding mill liners supplied for cement mills with throughput ratings from 80 t/h to 400 t/h.
Kiln nose rings and chain systems use ZG40Cr25Ni20Si2 grade (ASTM A297 HK) with creep rupture strength above 80 MPa at 850°C. Grinding mill table liners and roller tires employ CrC overlay on high-chromium base (ZGCr28), with surface hardness HRC 56-62 and overlay thickness 6-12 mm. Standard liner plate sizes: 300×400 mm to 1200×1500 mm. Custom alloy compositions developed for specific fuel types including petcoke and biomass.
ISO 9001:2015 certified (GICG UK). Authorized SSAB Hardox Wear Parts Center (APC-17-29). Two utility patents in heat-resistant alloy formulation and hardfacing process. Supplied to LafargeHolcim regional subsidiaries and major Southeast Asian cement groups.
90-day standard warranty. Heat treatment charts and material chemistry reports provided per batch. Each casting undergoes UT inspection and Rockwell hardness testing before dispatch. Factory address: Luoyang Zhili New Materials Co., Ltd., Luoyang, Henan, China.
Power Industry
Supplied coal mill grinding components to thermal power plants in China’s Shanxi and Inner Mongolia coal bases since 2005. Slag handling components delivered to cogeneration plants in Hebei and Shandong provinces, operating in high-temperature corrosive environments with daily thermal cycling. Roller press wear parts supplied to power station raw material grinding lines with documented service life records.
Coal pulverizer roller shells: ZG50Cr5Mo alloy steel, HRC 48-55, designed for thermal shock resistance during daily start-stop cycles. Overlay thickness 5-10 mm on wear faces. Standard roller shell OD: 600 mm to 1,500 mm; shell length: 300 mm to 1,800 mm. Slag pot inserts and furnace tuyere components: ZG40Cr25Ni20 grade, rated for continuous operating temperatures up to 1,200°C. Roller press grinding rings: chrome-moly alloy with CrC overlay, HRC 55-60, for coal and limestone grinding applications.
ISO 9001:2015 certified (GICG UK). Authorized SSAB Hardox Wear Parts Center (APC-17-29). In-house heat treatment furnace with programmable temperature profiles for consistent quenching and tempering results. Metallurgical laboratory on site for chemistry verification.
90-day warranty. Full traceability documentation with heat treatment charts. Chemical composition reports available per cast heat. Contact: +86 17842421247 | info@zlcrusherpart.com
Metallurgy Industry
Heat-resistant castings supplied to domestic steel plants and international steel operations since company founding in 1992. Ladle shrouds and tundish nozzles delivered to continuous casting lines with annual steel output exceeding 10 million tons. Slag runner components operating in steelmaking shops with tapping temperatures above 1,600°C.
Steel ladle components: ZG40Cr25Ni20Si2 (HK40, ASTM A297) and ZG35Cr24Ni7SiNRe (HN grade) for operating temperatures up to 1,150°C in ladle linings and 1,250°C in slag runners. Tundish impact pads and wear plates: ZG30Cr18Mn12Si2N, austenitic heat-resistant grade. Custom alloy compositions developed for specific furnace chemistries including basic oxygen furnace (BOF) and electric arc furnace (EAF) environments. Non-standard geometries cast from 3D printed sand molds for complex shaped components.
