XJS800 Cone Crusher Comprehensive Analysis

I. Equipment Overview

The XJS800 cone crusher is an outstanding crushing equipment with various crushing cavity types to meet different crushing requirements. It mainly consists of a frame, a transmission device, an eccentric sleeve, a main shaft, a moving cone liner, a fixed cone liner, an adjustment device, a lubrication system, a hydraulic system and other parts.

III. Eccentricity-related Characteristics and Application Strategies

1. Eccentricity Principle and Influence

The eccentricity is the distance that the main shaft and the moving cone liner move when the eccentric sleeve rotates one circle, which depends on the combined eccentricity of the eccentric sleeve and the bushing. Adjusting the eccentricity can meet all application requirements. A larger eccentricity means higher production capacity and greater driving power.

2. Application Scenarios and Methods of Medium and Small Eccentricities

- Optimization of Packed Feeding: Eccentricity adjustment can achieve packed feeding conditions at different feeding rates to maximize production, product particle shape and crushing ratio. By reasonably adjusting the eccentricity, the material in the crushing chamber can be evenly distributed and in an efficient crushing state. Whether it is coarse crushing, medium crushing or fine crushing operations, the best packed feeding parameters can be found according to the material characteristics and production requirements.       

- Power Consumption and Discharge Port Control: A small eccentricity can reduce power consumption and piston load and help to achieve a smaller closed-side discharge port. In scenarios where finer product particle size is required and energy consumption needs to be controlled, such as in the production of high-quality construction sand or fine chemical raw materials, using a small eccentricity can reduce production costs while ensuring product quality. The best product particle shape is usually achieved under a similar closed-side discharge port setting. A small eccentricity is beneficial to stabilize the discharge port size, thereby producing products with uniform particle size and good shape.        

- Control of Fine Powder Content and Particle Size: A small eccentricity can minimize the fine powder content. In some applications with strict restrictions on the fine powder content in the product, such as in the production of specific graded concrete aggregates or high-end building materials, adjusting a small eccentricity can reduce unnecessary fine powder generation. At the same time, a small eccentricity can reduce the maximum particle size of the product to reduce the circulating load. In the continuous production process, this helps to reduce the number of circulation times of the material in the crushing system, improve production efficiency and reduce equipment wear.        

- Prevention of Blockage Risk: If the XJS800 crusher feed contains a large amount of fine powder, a small eccentricity can reduce the blockage risk. When processing some ores or recycled aggregates with more fine powder, a smaller eccentricity can make the material flow inside the crushing chamber more smooth, avoid blockage caused by fine powder accumulation and ensure the stable operation of the equipment.
