Grate plates and diaphragms for crushers and grinding mills, cast in manganese steel, Cr-Mo alloy or high-chromium iron. Zhili controls slot pitch, plate flatness and hole positions so the discharge opening and the airflow or material path stay exactly as designed.

If you need detailed technical information, drawings or a price for a size we have not listed, please email us at cnwearparts@lyzhili.com — we are a customized factory for crusher and mill wear parts and we quote quickly.

Discharge control for crushers and mills

Grate plates and diaphragms set what leaves the machine and how fast. Distorted slots change gradation, load balance and power draw. Zhili casts these parts with controlled shrinkage, machines the mounting and sealing faces and checks slot pitch, so replacements restore the original opening size.

Key features

  • Slot openings, hole patterns and thickness to specification
  • Flat, machined mounting faces to avoid gaps and bypass
  • Segmented or single-piece plates for easier handling
  • Ribbed designs for large unsupported spans
  • Chemistry, hardness and dimensional reports included

Materials

  • Mn13Cr2 / Mn18Cr2 – general purpose, impact tolerant
  • Cr-Mo alloy steel – large plates requiring strength
  • High-chromium white iron – maximum abrasion resistance

Applications

Hammer and impact crushers, ball and rod mills, clinker breakers and coal mills in cement, mining, power and aggregate plants.

Why buyers choose Zhili

  • Reproduction of existing patterns from drawing or sample
  • Advice on slot size and open area to hit your product target
  • Consistent quality with documented inspection
  • Export packing that protects slot edges

Ordering and support

Customized Solutions

Customized according to your operating conditions

High-wear working conditions

For highly abrasive materials such as limestone and sandstone, we adopt high-chromium cast iron or ceramic composite materials, which extend the service life by 3 to 5 times.

High-impact working conditions

For high-impact materials like construction waste and metal ores, we adopt a reinforced structure with high manganese steel and alloy bars, delivering excellent impact resistance.

High-temperature working conditions

For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
