Introduction to Equipment Wear Parts and Design Advantages

Crusher Hammer Head

Crushing Gear Ring

Crushing Disc

The pulverizing hammerheads within the equipment are primarily utilized for the shearing and impact grinding of materials. Depending on the specific characteristics of the client's materials, we can employ various materials such as carbon steel, alloy steel, ceramics, or tungsten carbide. These hammerheads undergo high-temperature forging to ensure exceptional wear resistance; under standard operating conditions, they generally require no replacement. When used for pulverizing materials characterized by high hardness and significant abrasiveness, their service life can exceed 2,000 hours.

The crushing ring gear within the equipment is primarily utilized for the impact grinding of materials; it assists the hammer heads in the crushing process and enhances the equipment's shearing capability. Depending on the specific characteristics of the client's materials, we offer a selection of materials for the ring gear, including carbon steel, alloy steel, ceramics, and tungsten carbide. Like the hammer heads, the ring gear undergoes high-temperature forging, endowing it with exceptional wear resistance; under standard operating conditions, replacement is rarely required. For the crushing of materials characterized by high hardness and significant friction, the ring gear features a quick-change design, allowing for rapid disassembly whenever replacement or cleaning becomes necessary. Its service life exceeds 2,000 hours.

The toothed ring of the pulverizing disc within the equipment primarily serves to support the hammerheads during high-speed rotation, thereby assisting them in crushing the material. Depending on the specific characteristics of the client's material, we can utilize various materials—including carbon steel, alloy steel, ceramics, or tungsten carbide. These components undergo high-temperature forging to ensure exceptional wear resistance; under standard operating conditions, replacement is rarely required. Furthermore, the pulverizing disc undergoes high-speed dynamic balancing to ensure that it exhibits absolutely no angular deviation during high-speed rotation.

Packaging & Shipping

We design, we manufacture, and we deliver.

We design, we manufacture, and we deliver.
We utilize fumigation-free wooden crates for packaging—a solution that fully complies with international export standards. Each crate is structurally reinforced and secured, lined internally with shock-absorbing foam, and hermetically sealed to provide protection against moisture and dust.
Externally, every crate is reinforced with steel strapping and fitted with anti-collision corner guards, followed by a protective wrapping of waterproof plastic film. This comprehensive packaging methodology effectively mitigates potential risks associated with long-distance sea and land transport—such as impact damage, compression, moisture ingress, and dust accumulation.
We offer both Full Container Load (FCL) and Less than Container Load (LCL) shipping services. Our professional export packaging standards fully satisfy all international logistics and customs clearance requirements; furthermore, as our packaging requires no fumigation, it significantly accelerates the customs clearance process and reduces overall logistics costs.
Our specialized packaging team exercises rigorous oversight throughout the loading, securing, and strapping procedures. Concurrently, we provide a complete suite of shipping marks, packing lists, and export documentation to ensure that your cargo arrives at its overseas destination safely, intact, and on schedule.
