Breaking Through Bottlenecks in Non-metallic Ore Crushing Processes: Causes of Over-crushing and Blockage and On-site Commissioning Techniques

Non-metallic ore crushing is a crucial process in various industries, and optimizing this process can significantly enhance productivity and economic benefits. This article provides a comprehensive analysis of the entire non-metallic ore crushing process, from primary to secondary crushing, and explores how the PEW Jaw Crusher can help break through common bottlenecks.

Process Flow Analysis

The non-metallic ore crushing process typically consists of several key stages. In the primary crushing stage, large ore blocks are reduced to smaller sizes. The goal here is to achieve a suitable feed size for the subsequent secondary crushing. The secondary crushing further refines the ore particles to meet the specific requirements of the end - use. Different types of equipment play vital roles in each stage. For example, jaw crushers are commonly used in the primary crushing stage due to their high capacity and reliability.

PEW Jaw Crusher: The Innovative 'V' - Shaped Crushing Chamber

The PEW Jaw Crusher features an innovative 'V' - shaped crushing chamber design, which sets it apart from traditional jaw crushers. In terms of crushing ratio, the PEW Jaw Crusher can achieve a ratio of up to 6:1, compared to the average 4:1 of traditional models. This means it can produce finer particles with fewer passes, increasing overall efficiency. In terms of energy consumption, tests have shown that the PEW Jaw Crusher can reduce energy consumption by up to 20% compared to traditional jaw crushers, thanks to its optimized design that minimizes unnecessary energy loss during the crushing process. Moreover, its stability is significantly improved, with a lower failure rate of about 15% compared to traditional models, ensuring continuous and reliable operation.

Case Studies: Ore Characteristics and Parameter Adjustment

Let's take limestone and granite as examples. Limestone is a relatively soft ore with a Mohs hardness of about 3. For limestone crushing, the PEW Jaw Crusher can operate at a higher speed and larger discharge opening, which can increase the production capacity by up to 30% compared to standard settings. On the other hand, granite is a hard ore with a Mohs hardness of about 6 - 7. When crushing granite, the crusher needs to be adjusted to a lower speed and smaller discharge opening to ensure proper crushing and prevent over - wear of the crushing chamber. By adjusting the parameters according to the ore characteristics, the PEW Jaw Crusher can achieve optimal performance.

Solving Typical Process Problems

Over - crushing and blockage are two common problems in non - metallic ore crushing processes. Over - crushing not only wastes energy but also produces excessive fine particles that may not meet the product requirements. Blockage can lead to production downtime and increased maintenance costs. To diagnose over - crushing, operators can analyze the particle size distribution of the crushed product. If the proportion of fine particles is significantly higher than expected, it may indicate over - crushing. To solve this problem, adjusting the crusher parameters such as the discharge opening size and the rotation speed can be effective. For blockage, regular inspection and cleaning of the crushing chamber, as well as proper feeding control, can prevent blockage from occurring.

In conclusion, the PEW Jaw Crusher offers a reliable solution for non - metallic ore crushing processes. Its innovative design, high efficiency, and energy - saving features make it an ideal choice for businesses looking to improve their productivity and economic benefits.
