齒輥破碎機的破碎齒輥是齒輥破碎機的關鍵配件，傳統破碎齒輥多以合金模具鋼鑄造，利用合金模具鋼的硬度高，強度高的特點來提高耐磨性。破碎齒的工作狀況具有高沖擊，高頻率，高耐磨等特點，所以對材質性能要求既有高耐磨性，又具備抗沖擊性，這兩點決定了其使用壽命。 DJM選用馬氏體鋼復合陶瓷鑄造制作破碎齒輥，采用粉末冶金制芯結合鑄造工藝，在馬氏體鋼表面鑄入陶瓷顆粒形成陶瓷金屬復合材料加強筋，這層復合層的耐磨性能可達合金鋼的3–4倍，同時這一復合層的厚度可制成達到原備件厚度的1/3，在保持馬氏體鋼原有的高強度耐沖擊性能的同時提高了馬氏體鋼的耐磨強度，陶瓷復合材料的壽命約為合金鋼材料的3-4倍以上。提高齒輥工作面的抗磨性能，從而獲得即耐磨且抗沖擊的破碎齒輥。

Roller tooth is the key part of the roller crusher, the traditional tooth is usually casted out from high-chromium cast iron or alloy tool steel to improve its wear resistance by high hardness of the material.  The working condition of the tooth requires it to be against high impact, high-frequency and high wear resistance.In order to improve the wear and impact resistance of the tooth, DJM selects Martensite steel ceramic composite materials, which forms the ceramic metal composite reinforcement through injection of ceramic particles into the Martensite steel, the composite layer hardness is harder than high Cr material 3-4 times, at the same time, the composite layer thickness can be made to a third of the thickness of the original spare parts. Life span of the ceramic composite material is more than 2 times of a high Cr alloy material. Both feature of impact resistance and wear resistance of the tooth is achived after improving the wear resistance of the working surface.
