Toothed rollers, roll shells and sleeves for twin roll crushers, sizers and primary coal or limestone crushers. Zhili casts the tooth profile and pitch to your drawing in high-chromium iron or Mn-Cr alloy, so gripping, throughput and product size stay as designed through the wear life.
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.
Toothed rollers must keep gripping the feed, and the moment tooth height drops, throughput falls and slip wear accelerates. Zhili casts complete rollers or replaceable shells and sleeves with controlled tooth height, pitch and helix angle, using alloys selected for the abrasiveness of your material.
Twin roll and sizer crushers in coal handling and power stations, limestone and clay crushing in cement plants, mineral sizers in mining, coke and sinter plants.
Provide drawings, OEM numbers or a worn roller for measurement. Our engineers will confirm alloy, tooth geometry and lead time, and can advise on the best shell design for your throughput.
Share your drawing, OEM part number, operating conditions or a photo of the worn part. Zhili will confirm the recommended alloy, weight and lead time, and can supply trial pieces for a first plant test.
Standard wear-resistant material with excellent impact resistance and work hardening properties.
Enhanced wear resistance with embedded alloy bars for superior performance in high-abrasion conditions.
Advanced ceramic composite matrix reinforcement technology for extended service life.
Bimetal composite structure combining wear-resistant surface with tough core material.
Excellent wear resistance with good hardness retention at elevated temperatures.
Rebuilding and reinforcement using advanced hardfacing welding technology.
Customized according to your operating 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.
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.
For high-temperature materials including cement clinker and slag, special heat treatment is adopted to retain hardness and wear resistance at elevated temperatures.
We will fully understand your working conditions and recommend the most appropriate material selection. Provide drawings based on your machine models and spare parts dimensions.
