Conical Crusher Spare Parts – Moving and Fixed Cone Liners – Crusher Liners DM-15

Wear-resistant cone crusher spare parts—core components ensuring stable equipment operation

As a core piece of equipment in the mining and aggregate industries, the performance of cone crushers is closely linked to the quality of their spare parts. These critical wear parts of cone crushers directly affect crushing efficiency and service life.

Analysis of the Names and Functions of Core Cone Crusher Parts

1. Moving Cone Lining & Fixed Cone Lining

◎ The fixed cone liner is located in the upper part of the crushing chamber and, when paired with the moving cone, forms the crushing zone, ensuring uniform material crushing.

◎ The moving cone liner is in direct contact with the material and subjected to high-intensity impacts; its wear resistance determines both the crushing efficiency and the replacement cycle.

2. Eccentric sleeve & spindle

◎ The eccentric sleeve drives the main shaft to rotate, which in turn causes the moving cone to perform an eccentric motion, thereby achieving the crushing and breaking of the material.

◎ As the core component for power transmission, the spindle must possess high strength and fatigue resistance.

3. Bearing & Sealing System

◎ The bearing supports the rotation of the spindle, reduces frictional losses, and ensures smooth operation of the equipment.

◎ Seals prevent dust from entering, thereby extending the service life of wear parts in cone crushers.

The core advantages of cone crusher spare parts

1. Broad applicability

◎ Cone crusher spare parts are suitable for secondary and tertiary crushing, enabling efficient processing of hard rocks, abrasive materials, and soft minerals.

2. Reduce downtime and improve efficiency

◎ The wear parts of the modular-designed cone crusher—such as the moving cone liner, stationary cone liner, and crusher liners—are easy to replace, ensuring continuous production.

3. Significantly reduce costs

◎ Optimize the crushing process to reduce energy consumption and component wear rate.

4. Safety and Environmental Protection

◎ Based on analysis of wear curve data, the risk of human intervention is reduced; efficient crushing minimizes the need for multi-stage operations, thereby lowering energy consumption and carbon emissions.

5. Ensure stable finished product quality

◎ Precisely designed cone crusher parts—such as the moving cone liner and stationary cone liner—ensure uniform product particle size, meeting the stringent industry standards for applications like asphalt and concrete.

What materials are used for the moving cone and stationary cone liners?

Standard material

Class C Austenitic Manganese Steel

Manganese: 13% Chromium: 2%

Suitable for moderately hard, non-abrasive rocks such as limestone and dolomite.

D-grade austenitic manganese steel

Manganese: 18% Chromium: 2%

Suitable for common ores such as granite and basalt. The formula has been improved with the addition of chromium alloy. After heat treatment, the hardness is significantly enhanced, and wear resistance is improved.

E-grade austenitic manganese steel

Manganese: 24% Chromium: 2%

Special materials for extreme operating conditions

Element TiC

Element TiC—a lining made from standard alloys C, D, or E and reinforced with titanium carbide inserts. It offers higher resistance to impact loads and crack propagation.

Conical Crusher Spare Parts and Services

01/Conical crushers are used in ore processing. These crushers reduce large rocks and ores into smaller sizes. They get their name from their cone-like shape. Conical crushers can decrease the size of ores or large rocks, making it easier to extract valuable materials and process waste. A conical crusher works by applying force between its walls, causing the rocks to break or deform into smaller sizes.

02/ Since the machinery must withstand significant mechanical stress, regular maintenance is crucial. Consequently, the minerals and ore industry has a strong demand for cone crusher service providers. These providers are responsible for addressing normal wear and tear on the machinery and replacing any damaged components, if necessary.

03/ Cone crusher manufacturers exercise exceptional care during the manufacturing process to ensure compliance with quality standards, as damage to the machine could result in loss of user resources. Cone crushers are available in a wide range of sizes and offer customized services to meet customers’ specific needs. Since mobile cone crushers are primarily used at mining sites, manufacturers also produce mobile cone crushers tailored to customer requirements. Throughout the production process, cone crusher manufacturers consistently prioritize the quality of their machines.

04/Conical crushers are used to efficiently crush extremely hard rocks. The material fed into a conical crusher can be either dry or wet. The conical crusher reduces the size of the crushed material by a ratio ranging from as high as 5:1 to as low as 3:1. Conical crushers typically process quarry materials—rocks and aggregates extracted from mines and open-pit sites. They are also used for crushing gravel. Conical crushers are an ideal choice for low-cost configurations. They offer high productivity and are easy to adjust and maintain.

FAQ

Q: What are the advantages of cone crushers?

Answer: The cone crusher can crush all types of medium-hardness ores and rocks. It also boasts numerous advantages over other crusher designs, such as low energy consumption, high reliability, high efficiency (compared to other crushers), and a high reduction ratio (the ratio of feed/input size to product/output size).

Q: How do I maintain a cone crusher?

Answer: Maintenance method: Users must inspect and clean the oil supply filter, return oil filter, and strainer monthly. They also need to monitor changes in oil quality to ensure that the working pressure remains between 0.08 and 0.15 MPa.

Q: What is the main shaft of a cone crusher?

Answer: The spindle is made of high-quality forged steel and has undergone annealing treatment to relieve internal stresses. The spindle has a conical shape that fits precisely into the center of the head. At the bottom of the spindle, there is a polished bronze stepped bearing. The journal of the star-shaped bearing consists of a sleeve fitted over spindles with diameters of 51 inches, 60 inches, and 84 inches.
