Product Description

Our HP300 Bowl Liner and Mantle are precision-manufactured wear-resistant spare parts tailor-made for Nordberg HP300 hydraulic cone crushers, specially engineered to withstand severe abrasion, frequent impact and heavy-load working conditions in mines, quarry aggregates and stone processing fields. As core crushing consumables, these two liners dominate the whole crushing procedure of hydraulic cone crushers, featuring outstanding anti-abrasion property, stable mechanical performance and prolonged service lifespan while guaranteeing even finished grain size during continuous high-intensity ore crushing.

What are Bowl Liner and Mantle?

Bowl liner and mantle serve as the indispensable core wearable components of HP300 hydraulic cone crusher. The bowl liner (also named concave) is fixed inside the adjustment ring as stationary lining, while the mantle is tightly mounted on the movable cone head as rotating lining. The pair of liners jointly form the complete crushing cavity. When equipment operates, the eccentric gyration of movable cone drives mantle to squeeze, grind and pound raw stones and ores against fixed bowl liner to realize material fragmentation and particle shaping. Their casting quality, machining precision and wear resistance directly decide crusher output efficiency, finished aggregate quality and overall equipment running cost of crushing stations.

High-Quality Materials for Superior Performance

We adopt premium customized casting raw materials to produce HP300 crusher liners, realizing optimal matching among material hardness, impact toughness and abrasive resistance. Three mainstream material options are

available for different working conditions as below:

High Manganese Steel (Mn13Cr2)

With excellent intrinsic toughness and strong instantaneous impact resistance, this material can generate obvious work hardening effect under repeated ore hitting, continuously raise surface hardness during operation. Perfectly applicable for coarse and medium crushing of medium-hard rocks such as limestone, dolomite and common iron ore.

Alloy Modified High Manganese Steel (Mn18Cr2)

Optimized metallurgical formulation with added chromium, molybdenum and other trace alloy elements greatly upgrades wear resistance and anti-cracking capacity. Effectively prevents brittle fracture under complex alternating impact loads, widely used for medium and fine crushing of abrasive granite, basalt and hard metallic ores.

High-Chromium Alloy Reinforced Steel (Mn22Cr2 + TIC Optional Insert)

Upgraded high-alloy grade with optional titanium carbide embedded reinforcement for ultra-severe abrasion scenarios. Boasts top-level wear performance among three materials, ideal for ultra-hard high-abrasive raw materials like quartz stone, taconite ore and sharp gravel.

Key Features

·Outstanding Abrasion Resistance: Advanced integral sand casting + multi-step tempering heat treatment technology effectively improves liner surface hardness, slows down material abrasion under long-term hard rock friction and extends service cycle remarkably.
·Excellent Anti-Impact Toughness: Scientific alloy composition avoids liner crack, deformation and early scrapping under sudden massive feeding impact, lowering unexpected equipment shutdown risks.
·Original Cavity Profile Design: Strictly produced per HP300 original OEM dimension parameters; standardized crushing cavity ensures unobstructed material falling, uniform finished particle grading and stable crusher processing capacity.
·High Dimensional Compatibility: Precise casting tolerance ensures seamless installation matching standard HP300 hydraulic cone crushers without any on-site cutting or modification work.
·Economical Operation Cost: Longer service life reduces spare part replacement frequency, cuts manual replacement labor cost and minimizes crusher downtime loss effectively.
