During the operation of the crusher, material jamming or clogging often occurs. It seriously affects production capacity, equipment life and operating efficiency. Through many years of practical observations at crushing stations, it can be seen that operating errors, inappropriate material selection or installation errors are the main causes of this phenomenon.<\/span><\/p>\n

The article below will analyze the causes and propose solutions. Help businesses overcome the problem of material jamming in the crusher.<\/strong> Ensure stable operation of the production line, optimizing production efficiency.<\/span><\/p>\n

1. Main causes of material jamming in the crusher<\/strong><\/span><\/h2>\n

1.1 High humidity and adhesion of raw materials<\/strong><\/span><\/h3>\n

The most common cause of mill jamming is the high moisture content of the input material. When the raw materials have a high water content, they easily stick together and stick to the internal parts of the mill. This is especially serious with the lines cone crusher<\/a><\/strong>, jaw crushing<\/a><\/strong>, and VSI crusher<\/a><\/strong>.<\/span><\/p>\n

For example, in the process of crushing limestone or clay with high moisture content, small particles are easy to stick to the crushing hammer, crushing jaw or lining plate, forming a layer of hard material that causes the machine to operate inefficiently or stop completely.<\/span><\/p>\n

1.2 High viscosity or contains many impurities<\/strong><\/span><\/h3>\n

Some natural stones have a high clay content or contain many organic impurities, which increases the viscosity of the material. When entering the crusher, these particles cannot separate from each other but form a sticky mass, leading to blockage in the crushing chamber.<\/span><\/p>\n

This often occurs when crushing basalt or mudstone with a high clay content, reducing the material release capacity and increasing the risk of machine jamming.<\/span><\/p>\n

1.3 Raw materials are overloaded or not suitable for the equipment<\/strong><\/span><\/h3>\n

Each type of crusher has a limit on the size of the input material. If the material is too large or has the wrong shape, the machine will not be able to process it quickly enough. This leads to clogging.<\/span><\/p>\n

For example, if jaw crusher<\/a><\/strong> Designed to handle maximum size rocks 500mm<\/strong> but input materials up to 700mm<\/strong>, it is very easy to get material stuck, overloaded or broken grinding shaft.<\/span><\/p>\n

1.4 The discharge slot is smaller than necessary<\/strong><\/span><\/h3>\n

Another important cause is that the discharge slot of the crusher is not adjusted properly. When the discharge slot is too small, the crushed material cannot be discharged quickly, causing stagnation in the crushing chamber. If not handled promptly, this situation will cause the machine to stop working. There is a possibility of increased risk of damage.<\/span><\/p>\n

1.5 Errors in operation and maintenance<\/strong><\/span><\/h3>\n

Improper operation or inadequate maintenance can also cause material jamming. Some common errors include:<\/span><\/p>\n
