Import Crusher Crushing Shaft Set For Coal Mine — Buy in wholesale FOB from Supplier in China

The Crusher Crushing Shaft Set for Coal Mine supplied by Henan Shuangzhi Machinery Equipment Co., Ltd. is a complete assembly designed for the impact‑crushing stage of coal mining operations. The set comprises a crushing shaft, cutter‑tooth base, cutter tooth, flat key, bearing, seal and fastening bolt, each machined to maintain high precision and stiffness. Design guidelines require that the rotating part never contacts the crusher box and that the clearance to the box wall is equal all around the circumference. Fastening bolts must remain tight, the cutter body must stay free of cracks, and manual rotation should be smooth and free of abnormal noise.

In the mining equipment sector shafts of this type are normally forged from medium‑carbon steel and heat‑treated to a hardness of 45‑55 HRC, which provides the wear resistance needed for repeated hammer‑head impacts. Typical shaft diameters are around 200 mm with a dimensional tolerance of ±0.1 mm, allowing the high rotation speeds of up to 1 500 rpm commonly specified for coal‑crusher applications. The assembly usually incorporates a double‑row ball bearing and an oil‑seal to contain lubrication and keep out dust, while a flat key transmits torque without slippage. These industry‑standard components give the shaft the rigidity required to withstand the large impact loads generated by the hammer head.

The shaft set is intended for integration with trough crushers used in underground or surface coal mines, and buyers are typically equipment importers or mine‑site maintenance contractors. Procurement terms such as minimum order quantity, packaging format and incoterm are not disclosed in the listing and should be confirmed directly with Henan Shuangzhi Machinery Equipment Co., Ltd.
