Xinhai Mining Crushers: Built to International Standards for Reliable Mine Crushing

From the instant ore enters the crushing circuit, equipment performance sets the tone for the entire production line’s efficiency and profitability. As a flagship product developed in-house by Xinhai Mining, the XHC series crushers combine cutting-edge design and precision manufacturing with nearly three decades of real-world mining experience.

Drawing on advanced digital R&D capabilities and extensive project expertise, Xinhai’s XHC series delivers efficient solutions spanning primary to secondary and fine crushing—helping mines achieve higher throughput, lower energy consumption, and more stable operation.

Digital Innovation at the Core

The XHC series was developed by Xinhai’s Intelligent Equipment Research Institute using a fully digitalized approach. By integrating theoretical research, field experience, and intelligent technologies, the team employed advanced 3D modeling, dynamic simulation, and finite element analysis to optimize every aspect of the design. This rigorous process ensures outstanding reliability and long service life from day one.

XHC Jaw Crushers: A Solid Foundation for Primary Crushing

In primary crushing, the XHC jaw crusher stands out for its robust engineering and thoughtful design details:Its weld-free, detachable frame structure offers excellent fatigue resistance and eliminates the common risk of cracking caused by internal stresses found in traditional welded frames. The crusher is equipped with SKF large-clearance spherical roller bearings, with installation clearances strictly controlled to prevent overheating, premature wear, and unexpected failures.An integrated motor base design reduces vibration-related drive system issues, lowers civil works costs, and shortens on-site installation time.

The deep V-shaped crushing chamber was optimized using discrete element and dynamic simulations to achieve the ideal jaw motion trajectory and crushing geometry. This results in better inertia, effective stroke, and full release of crushing capacity. Careful counterweight optimization, validated through simulation, minimizes unbalanced forces. Paired with an elastic vibration-damping foundation, it significantly reduces stress on the structure, extends equipment life, and simplifies foundation design.

Operators benefit from quick and easy discharge opening adjustment using either mechanical or hydraulic wedge systems, which reduces labor intensity and speeds up maintenance. Standard jaw plates are made of high-quality ZG120Mn18Cr2 manganese steel for long wear life and fewer replacements.

For extreme conditions, even more durable custom materials are available.

XHCH/XHCS Single-Cylinder Hydraulic Cone Crushers: Efficient and Reliable for Secondary and Fine Crushing

The XHCH/XHCS series single-cylinder hydraulic cone crushers are engineered to handle medium to fine crushing of various ore types. Multiple chamber designs—developed according to layered crushing principles and liner wear characteristics—along with adjustable eccentric throw and an intelligent hydraulic tramp release system, deliver strong crushing force, high capacity, large feed acceptance, high uptime, and low failure rates.

Constant chamber geometry and specially designed liners ensure even wear, maximizing liner utilization and service life while keeping maintenance costs down.A dedicated PLC control system supports both local and remote operation, real-time health monitoring, and optional smart interconnection. The sensitive tramp release system, powered by bottom-mounted cylinders and hydraulics, protects the crusher from uncrushable materials and safeguards critical components.

An elastic damping foundation replaces traditional rigid connections, reducing transmitted forces, extending equipment life, and lowering foundation costs and construction time. For demanding sites, the crushers feature reinforced frames made of high-strength EN-standard cast steel, precision EN-tested components, high-grade spiral bevel gears, and multi-layered protection systems—ensuring stable performance even in harsh conditions.

SKF spherical roller bearings and rotary seals provide excellent stability and reliable, leak-free operation. High-lead bronze bushings offer superior load capacity and self-lubricating properties to protect the main shaft under challenging conditions. The imported automatic lubrication and hydraulic systems use premium components to guarantee continuous oil supply and prevent common failures.

Backed by Xinhai’s 10,000-ton integrated heavy equipment manufacturing base, the XHC series benefits from end-to-end control—from component machining to final assembly. This ensures consistently high manufacturing standards and delivers dependable, high-performance crushing solutions to clients worldwide.Moving forward, Xinhai Mining Group remains committed to its full-chain service model (EPC+M+O). We will continue strengthening independent R&D of core equipment, driving mining machinery toward greater intelligence, efficiency, and sustainability, and building a globally competitive portfolio of high-end mining solutions that support the industry’s long-term development.
