About Us

Zhangjiakou Red Apple Machinery Equipment Manufacturing Co., Ltd. was established in 2006. Located in the easily accessible Zhangjiakou City, Hebei Province, it is an advanced local foundry enterprise focusing on the R&D and manufacturing of high-end wear-resistant parts. For more than a decade, we have adhered to the cultural philosophy of "Stability, Development, Reform, and Innovation," striving to become an industry leader in the R&D and manufacturing of wear-resistant castings. The company's General Manager, Qiao Aiyun, was awarded the title of "Advanced Self-Employed Entrepreneur" by the provincial Party committee and government in 1999, and has been commended by provincial, municipal, and county governments multiple times. With outstanding comprehensive strength, the company was awarded "Hebei Province Quality-Focused and Trustworthy Integrity Demonstration Unit" and "Level 3 Enterprise for Safety Production Standardization (Machinery)" in 2014.

Guided by high technology, the company has maintained deep industry-university-research cooperation with Hebei Polytechnic University and East China University of Technology for many years, continuously promoting the application of new materials and technologies. We actively undertake and participate in tackling cutting-edge technologies in the industry:

  • 2021-2024: Participated in the SME R&D project by the Science and Technology Department of Hebei Province — ZTA Manufacturing Process for Chrome Ceramic Composite Blow Bars and Hammers.
  • 2025-Present: Continuing to participate in the project by the Science and Technology Department of Hebei Province — ZTA Manufacturing Process for Ceramic Composite Jaw Plates.

Relying on reliable quality and comprehensive after-sales service, our company has gradually expanded its scale. Our products are sold well both domestically and internationally, winning the deep trust of a vast number of users and becoming a "reassuring choice" for our customers.

  • Domestic Market Reach: Extending east to Dandong and Dalian, north to Manzhouli and Inner Mongolia, and west to Hami and Kashgar in Xinjiang, as well as Baiyin in Gansu, among other regions.
  • International Export Business: Indirectly exporting high-quality castings to the United States, Japan, and other overseas countries through our network of distributors.
  • Our Trusted Clients: Large-scale industrial and mining enterprises including Pingshuo Group Coal Mine, Yuanping Power Plant, Shuozhou Huadian Power Plant, Ordos Coal Mine, Changzhi Lu'an Group Coal Mine, Zhangbei Hengtai Cement, SPIC (State Power Investment Corporation) Shanxi Aluminum Co., Ltd., and China Uranium Guyuan Company.

Whenever and wherever, all our employees spare no effort in their work, dedicated to the professional R&D and production of crushing engineering, mechanical equipment, and wear-resistant materials. "Your convenience is our pursuit; let's join hands in the new era to build the Chinese Dream together!" We look forward to achieving win-win development with partners from all sectors!

Our Core Product Series ● Product

We are professionally dedicated to the R&D and manufacturing of a full range of wear-resistant castings used in crushing engineering and mechanical equipment. Our products cover mining, building materials, metallurgy, chemicals, and other industries. Here is our core product matrix:

I. Hammer Crusher Series

  • Main Products: High-chrome composite hammers for mining/building materials, bimetallic alloy wear-resistant hammers, custom square/irregular shaped crusher hammers, low-vanadium high-chrome wear-resistant hammers, and high-vanadium high-wear-resistant hammers.
  • Technical Advantages: The hammer head core uses a high-chrome alloy cast iron base material, combined with a bimetallic alloy fusion process, completely eliminating casting defects such as cold shuts and cracks. The working part of the hammer head has a hardness of ≥HRC62. Combined with a high-quality low-alloy steel hammer handle, it truly achieves "hard but not brittle, tough and wear-resistant."
  • Applications: Mining, building material crushing, and metallurgical raw material processing industries; crushing medium-to-high hardness materials such as limestone, granite, coal, and ores.

II. Impact Crusher Series

  • Main Products: High-chrome blow bars for aggregates/ores, alloy wear-resistant blow bars, custom impact blocks, and counterattack blocks.
  • Technical Advantages: The working layer adopts high-chrome alloy material, accurately blending elements like chromium, vanadium, and titanium according to material characteristics. Using integral precision casting and directional solidification technology, the working layer hardness reaches ≥HRC60, and the service life is increased by 2 to 3 times compared to ordinary alloy parts.
  • Applications: Construction aggregate production, mining crushing, and road construction industries; crushing granite, basalt, limestone, concrete blocks, etc.

III. Jaw Crusher Series

  • Main Products: High-manganese steel/high-chrome jaw plates, movable jaw plates, fixed jaw plates, wear-resistant cheek plates (side liners), toggle plates, and alloy tooth plates.
  • Technical Advantages: Materials cover high manganese steel (ZGMn13 to ZGMn18Cr2) and high-chrome alloys. Adopting a bionic tooth shape optimized design, the high manganese steel can reach HB450 or above through work hardening under impact after water toughening treatment, greatly extending service life.
  • Applications: Primary and secondary crushing conditions, bearing high extrusion loads; crushing iron ore, limestone, quartz stone, coal, etc.

IV. Cone Crusher Series

  • Main Products: High-manganese steel/high-chrome bowl liners (concaves), mantles, and wear-resistant top liners.
  • Technical Advantages: The integral casting process ensures uniform wall thickness and zero casting defects, with compressive strength ≥800MPa. The structural design fits the cone crushing cavity type, improving crushing efficiency and uniformity while reducing uneven wear.
  • Applications: Spring, hydraulic, and compound cone crushers; secondary and tertiary crushing of high-hardness materials like granite, iron ore, and copper ore.

V. Mill Systems

  • Main Products: High-chrome/high-manganese steel ball mill liners, wear-resistant grinding balls, wear-resistant screen plates, and grate plates.
  • Technical Advantages: Adopting wave-shaped, step-shaped, or convex surface optimized designs to improve grinding efficiency; screen plates have a high opening rate without clogging. The liner hardness is ≥HRC55, featuring excellent wear resistance and good toughness, making it highly resistant to deformation and breakage.
  • Applications: Mining beneficiation, cement manufacturing, and chemical grinding industries; suitable for material grinding and classifying in various ball mills.

VI. Roller Crushers & Mineral Processing Equipment

  • Main Products: High-chrome toothed roller shells, wear-resistant roller teeth, crushing teeth, and bow tooth plates.
  • Technical Advantages: Roller shells use high-chrome composite alloys, while roller teeth use high-manganese steel or wear-resistant alloy steel. The composite casting process ensures a tight bond between the wear-resistant layer and the matrix, with no risk of tooth chipping or breaking, significantly boosting service life.
  • Applications: Coal crushing, mining beneficiation, and metallurgical screening; crushing coal, coke, shale, etc.

VII. Pump & Valve Components, Structural Parts & Other Special Castings

  • Main Products: Wear-resistant slurry pump casings, mud pump blades, excavator tooth roots/tips, loader bucket tips, concrete mixer blades, custom cast iron parts, and wear-resistant high-temperature (1050℃) furnace plate series.
  • Technical Advantages: High-chrome cast iron material guarantees excellent wear and corrosion resistance. Precision machining ensures smooth flow channels and superior sealing performance. We also offer personalized customization for various irregularly shaped wear-resistant castings based on complex working conditions.
  • Applications: Slurry conveying, chemical media transfer, construction machinery excavation, and harsh conditions such as high-temperature furnaces.
