The crusher is mainly used for crushing and forming soft, medium-hard and extremely hard stone. There are many models and types of crushers, so when the crushed materials are different, they may be adapted to different types of crushers, and the parameters such as discharge and feed of different crushers are also different. In daily production, the most used crusher equipment are jaw crusher, impact crusher, cone crusher, hammer crusher, etc. Choosing a suitable crusher equipment can not only reduce the crushing time and material waste, but also help the wear and tear of the crusher equipment. Below we briefly introduce:
Comparison of advantages and disadvantages of different crusher equipment
1. Jaw Crusher
Advantages: low price, easy to manufacture, strong applicability, simple structure and convenient maintenance.
Disadvantages: small crushing ratio, inconsistent crushing, uneven feeding, low efficiency, etc.
2. Impact Crusher
Advantages: The crushing ratio is large, the crushed material has a good particle shape, and the discharge particle size is adjustable.
Disadvantage: The liner is easy to wear, which leads to increased replacement and maintenance workload and serious dust.
3. Cone Crusher
Advantages: Large crushing ratio, uniform product size, suitable for medium and fine crushing of various ores and rocks, and less dust during work.
Disadvantages: The structure is complex, which makes the maintenance work complicated and the price is relatively expensive.
4. Hammer Crusher
Advantages: simple structure, easy operation, light equipment quality, convenient maintenance.
Disadvantage: The hammer head of the crusher wears quickly, so the production cost is increased.
Second, what factors need to be considered when choosing a crusher
1. The hardness of the material
Different types of materials have different hardness. The greater the hardness, the higher the difficulty of crushing. For crushing hard or medium-hard ores, jaw crushers should be selected as primary crushing equipment. For medium-hard or soft ores, jaw crushers should be selected Impact crusher or cone crusher.
2. Specifications of materials
If the size of the material is relatively large, the jaw crusher should be used as the primary crushing equipment. When the size of the stone is relatively small, other crushing equipment should be selected for combination, such as jaw crusher plus impact crusher or cone crusher. machine.
3. The humidity of the material
When choosing a crusher, you should also pay attention to the moisture content of the material. The moisture content will increase the humidity of the material, thereby increasing the viscosity of the material, reducing the discharge speed of the material, and reducing the production line rate. In severe cases, the discharge port may be blocked, causing the crusher to block materials and affecting the normal operation of the sand production line.
4. Incoming and outgoing particle size
One of the most important factors in choosing the type and grade of crushing equipment is the particle size of the incoming and outgoing materials. If the feed particle size is large, but the output particle size is small, it is necessary to use two-stage or multi-stage crushing.
If the material in the crushed material is larger than the size of the discharge port or the ratio to the width of the feeding port is large, the ratio of the particle size before and after crushing is large, and the crushing ratio to be achieved by the crusher is also increased, which will This leads to a reduction in the productivity of the crusher. On the contrary, if the crushing ratio is small, the production efficiency of the crusher will increase accordingly.
5. Production requirements
The output requirement of the production line is an important indicator for determining the crushing equipment. If the customer's production output requirements are larger, the required specifications and models of the crushing equipment will be larger, and the capital investment and output of the production line will increase.
What is the difference between jaw crusher and hammer crusher? Which is better to use?
The difference between jaw crusher and hammer crusher
1. Differences in working principles
The main crushing parts of the jaw crusher are two jaw plates. During operation, the movable jaw repeatedly approaches and leaves the fixed jaw, exerting multiple crushing forces on the material, so that the crushing of the material becomes smaller, until it is discharged after meeting the requirements, and the crushing is completed.
The main crushing component of the hammer crusher is the hammer head. During the hammering operation, the high-speed rotating rotor drives the hammer to continuously hit and cut the material, so as to achieve the purpose of crushing the material.
2. The difference between applicable materials
The jaw crusher has a wider range of applications and is suitable for crushing various materials with a compressive strength not exceeding 350MPa.
Hammer crusher is mainly suitable for crushing materials with compressive strength not more than 200MPa and moisture content less than 15%, such as cement, coal, coke, limestone, etc.
3. The difference between the particle size of incoming and outgoing materials
The jaw crusher has a feed size range of 125-1200mm and a discharge size range of 10-300mm, which is mainly used for coarse crushing of materials.
The feed particle size of the hammer crusher cannot exceed 1200mm, and the output particle size range is between 10-90mm. It can "one-hammer forming" the material. One hammer crusher is equivalent to jaw crusher + counterattack crusher, combining the two crushers into one crusher. , more energy saving.
Which one is better, jaw crusher or hammer crusher?
The jaw crusher is often used together with the secondary and tertiary crushing equipment in the production line. It is a coarse crusher for stone materials; the hammer crusher can be used alone and can achieve one-time crushing and forming. Therefore, it cannot be said which equipment is better to use, but which equipment is more suitable for your stone production line. Whether it is suitable or not is mainly from the aspects of crushed materials, production line scale, application method, etc.
If you are crushing materials with high hardness such as granite, quartz stone, iron ore, etc., it is recommended to choose a jaw crusher; if you are crushing materials with low hardness such as limestone and coal gangue, it is recommended to choose a hammer crusher.
If your work site is small, it is recommended to choose a hammer crusher, which can be crushed at one time. It only needs to be matched with auxiliary equipment such as a feeder to form a production line, which covers a relatively small area; and a jaw crusher needs to be matched with medium Fine crushing equipment, the entire production line will occupy a relatively large area when configured
The above introduces several factors that need to be considered when choosing a crusher. There are many types of crushers. In the face of a dazzling array of products, how to choose the production equipment that suits you is very important. Production efficiency and good economic benefits.
