1.Problem: The abnormal vibration of impact crusher. Reasons and Solution: There might be several reasons cause the abnormal vibration of impact crusher. The first one is the raw materials are too big. The operator should check the feed size of raw materials and separate the bulk ones out. The second one is the unevenly worn of the blow bar.

The blow bar is also an important part of the impact crusher. The blow bar is made of high-chromium alloy material and the latest manufacturing technology. It has a special structural design. The finished product is cubic, without tension and cracks, and the particle shape is quite good. It is very reliable and high resistance.

1.Problem: The abnormal vibration of impact crusher. Reasons and Solution: There might be several reasons cause the abnormal vibration of impact crusher. The first one is the raw materials are too big. The operator should check the feed size of raw materials and separate the bulk ones out. The second one is the unevenly worn of the …

Introduction of impact crusher machine; 11 types of mechanical failures and solutions. 1. No rotation when starting; 2. Bearing temperature raise; 3. Abnormal …

The amount of energy consumed in the world for crushing in material crushers is approximately 5%. Balancing the balance of power and, accordingly, the balanced use of the necessary resources will lead to a reduction in costs. Hammer crushers belong to impact crushers in which the crushed material is destroyed under the

Causes: When it is working, strong vibration and noise will be caused, and the temperature of rotor bearing rises sharply, which contributes to the damage of bearing and the …

The rotor of impact crusher has a large mass and a high speed. The casting deviation of the rotor and the mass deviation caused by the installation of blow bar will make the rotor produce unbalanced centrifugal force while rotating. The centrifugal force will make impact crusher generate forced vibrations, causing damage to bearings and other ...

Vibrations and fatigue cracks in the crusher frame will be nipped in ... impact crushers e.g. hammers and rotor ... Warping and wear of the jaw plate cause a change in the crushing chamber ...

The main objective is to design impact stone crusher. Impact stone crusher involves the use of impact rather than pressure to crush materials. The material is held within a cage, with openings of ...

There are three approaches to maintenance: reactive, preventative and predictive. Reactive is repairing something that has failed. Preventative maintenance is often viewed as unnecessary but minimizes downtime because the machine is getting repaired before failure. Predictive means using historical service life data to determine when a …

Due to the shortage of natural sand from rivers and seas, artificial sand production from large stones or rocks is being increased. However, this sand manufacturing process is dangerous and causes several social problems such as a high level of unwanted vibrations or noises. This study investigates the vibration characteristics of sand and …

The common causes of abnormal vibration of cone crusher as follows. 1. Overfeeding or uneven feeding. If feed too much materials, and exceeds the load of the cone crusher, the equipment will not be able to crush the materials in the crushing chamber in time, thus causing the accumulation of materials and producing abnormal vibration.

• crushing process is performed by dynamic impact of working elements on the crushed material, • the minimum vibration frequency of working element(s) is at least twice the maximum vibration frequency of the "classic" crushers working element(s), practically above 15 Hz. The main systematic of vibratory crushers can be presented as follows:

Cement Crusher Manufacturer. As a trusted cement crusher manufacturer, every Stedman crusher is engineered for a maximum feed size, target output size, and total capacity, but selecting a crusher on these criteria alone is merely half the task. These can be used as a cement crusher, mineral crusher, and many more.

The impact crusher is suitable for crushing different types of stones, it has large crushing ration, low unit of power consumption, it fully meets the standard of "more crushing less grinding" in a mineral process plant. With these advantages, impact crusher machine is widely used in metallurgy, mining, cement, chemical, refractory ...

There are many reasons that cause the vibration. For example, the unbalanced rotor will cause abnormal vibration. So just adjust the rotor will be fine. Also the over large materials may cause abnormal vibration. At this time, you shocked measure the size of the feeder …

Throughput (tons per hour) – Overfeeding a crusher can make the output more coarse, but it also causes a number of wear and longevity issues making overfeeding a major concern to avoid. Moisture – Moisture cushions the impact, producing a coarser product. Apron wear – Worn plates can be replaced or moved to areas of lower wear.

the crusher is operating, which will cause the crusher to vibrate and transfer to the fixed foundation of the crusher, reducing the service life of the foundation [5].

In addition, there are many other reasons can also cause abnormal vibration of the VSI sand making machine: 5. The base foundation is not firm or the anchor bolts are loose. When there is abnormal vibration in the sand making machine, first check whether it is caused by foundation and anchor bolts. If the foundation is not strong or the …

Causes of abnormal vibration of jaw crusher. First, the reason for the parts. ... After the jaw crusher has been working for a long time, the constant frictional impact with the material may cause some parts of the equipment to fall off, such as fixing bolts or severely worn parts. These falling parts are retained in the jaw crushing.
