When we use shredders, many customers will report uneven materials, some large and some small. Today, we will tell you the reasons and how to solve this problem. Main reasons 1. The tool is worn or the gap is too large (resulting in insufficient shearing and larger discharging granularity); 2. The screen is blocked or damaged (blocking the discharge of qualified materials, leadin……

Last time, I analyzed three reasons for the overload operation of the crusher. Today we will continue to discuss this topic. Reasons 1.The overload operation of crusher may also be caused by non-centered feeding. If the feed is concentrated on one side, it will form unilateral crushing. The crusher requires that the feeding must be centered, that is to say, the materials entering the……

Secondary materials, such as colored steel tiles and living thin materials, have regular grain shape and high density after being processed by crusher. How often does the equipment need to be overhauled after it is put into production? Let’s come in and discuss it today. Usually, equipment maintenance is mainly divided into three levels: minor repair, medium repair and overhaul. ……

Feed grading will affect the output of equipment. Today, let’s talk about the situation of putting large pieces of materials into the crusher production process. If large pieces of materials are often thrown into the crushing cavity, once the size exceeds the specified size, the materials may accumulate at the entrance of the crushing cavity and cannot enter the cavity for crushing. ……

What is the abnormal heat of the equipment during use? Then let’s talk about this problem and also solutions today. 1.The heat of crusher is usually related to bearing, and the locking of equipment shaft and bearing will directly lead to the heat of the machine body. The main causes of bearing fever include insufficient or excessive lubricating oil or oil aging; 2. Uneven installa……

Bearing peeling of crusher is one of the most common faults in bearing maintenance. This phenomenon will make the bearing surface appear uneven scale with sharp hook angle, and obvious abnormal sound can be heard during rotation inspection, which usually occurs on the raceway surface of the inner and outer rings of the bearing and the raceway surface of the roller. Next, I will analyze several ……

Oil leakage from crushers will cause a lot of harm, so today we will learn about the causes of oil leakage from crushers and the countermeasures. Oil leakage from crusher will cause multiple hazards, like equipment damage,efficiency decline ,potential safety hazard,and also increased maintenance cost. So I think it is necessary for customers who use metal crushers to know about the oil l……

The wearing parts of crusher include hammer head, screen and inner liner. Reasons 1. In the production process, due to operational errors or other factors, these vulnerable parts occasionally break, so they need to be replaced within a certain period, otherwise it will reduce the use efficiency of equipment and increase the load of the machine. Generally speaking, a pair of hammers can h……

The inflexibility of crusher bearings will lead to friction heat accumulation, raceway peeling and cage fracture, which will lead to violent vibration of equipment, energy consumption rising by 15%~30%, and may cause sudden shutdown and production line interruption. High temperature is easy to ignite oily dust and induce deflagration; Chain damage to gears, spindles and other parts, the mainten……

Crusher is a very commonly used equipment in secondary material treatment. In the production process, due to the material properties, some wear and tear often occurs. Today, let’s take a look at two common kinds of wear and tear of crusher. Firstly, the wear of hammer and screen. They are in direct contact with materials and are the main parts of crusher. Under normal wear and tea……

Hazard: The motor system is seriously damaged. –Overheating and burning of the winding: When the current exceeds the rated value, the motor winding will be heated sharply due to Joule thermal effect, and the insulation material will be accelerated to age and carbonize, which will eventually lead to turn-to-turn short circuit or ground breakdown, and the motor will be completely sc……

Both of these methods can be used, and each has its own advantages. Specifically, you can recommend the right one according to the needs of customers. Here is a brief introduction to the differences, advantages and disadvantages of these two methods. I believe you will be more clear after reading them. Motor the transmission shaft needs to be equipped with an 8-stage motor, while th……
