According to their structure and function The crushing equipment is divided into jaw crushers cone crushers, cone crushers, cone crushers cone crushers, roller crushers, roller crushers, rotary disk crushers, impact crushers and Hammer crushers.
Jaw crusher has the characteristics of large crushing ratio, uniform quality of product, easy structure, reliable operation, easy maintenance, economical operation cost, etc. Different materials that do not exceed 320MPa.
Cone crusher: high crushing ratio, high efficiency, uniform particle size, mainly used to crush fine and medium size of medium-hardness rocks.
Impact crusher: It is able to handle materials that have a width of 100-500mm, and its compressive strength is as high as 350MPa. Impact crushers feature large crushing ratios, small particles after crushing and uniform sizes of particles. It is used extensively in the stone crushing process for highway engineering. middle.
Hammer crusher: This is perfect for crushing hard minerals. The material's compressive strength should not exceed 100MPa and the humidity shouldn't exceed 15% You may get more info about crusher liners by browsing www.crusherparts.org website.
Considerations to make when choosing a crusher
When selecting a crusher, the type, hardness and size of the particles that are material coming in and going out, output and construction site of the crushed material should be thoroughly considered.
1. The material's toughness
Different kinds of materials have different degrees of hardness. In general, the greater the hardness, the greater the crushing difficulty coefficient. Jaw crushing equipment should be used for crushing medium-hard or hard stones. If you are crushing soft or medium-hard stones, cone crushers, counterattack or hammer crushers are able to be used directly.
2. Specifications of materials
The jaw crusher is used to crush large quantities of materials. But, if the stone is smaller or requires a specific gradation or gradation, a combination crusher and screening machine, like a jaw crushing, is needed. Cone or impact crushers are combined with an Hammer crusher.
3. The material's humidity
The choice of mill liners foundry is also affected by the material's water content. If the water content of the material is too large the fine-grained materials will become agglomerated or stick to the coarse-grained one because of the increased humidity, thereby increasing the viscosity and reducing the speed of discharge, and making the Productivity decrease. This can stop the discharge port from flowing and cause production to stop in certain instances.
4. The extent of the cleavage development of the ore
The amount of cleavage formation of the ore directly impacts the crushing efficiency. It is extremely easy to crush the ore along the cleavage surfaces when it is crushed. Therefore, the productivity of the crusher is much more than the ore with a thick structure, when the ore that has a developed cleavage is crushed. .
5. Incoming and outgoing particle size
The particle size of the incoming and outgoing dimension is used to assess the quality and level of crushing of the equipment needed for crushing. If the amount of fine particles (greater than the dimensions of the port for discharge) in the crushed material is large or the ratio of the largest block of ore to the width of the feeding port is huge, then the crushing ratio that the mill liners foundry must achieve (the particle size of the material prior to crushing and the size of the crushed material) The ratio of the particle size the material) is large, so the productivity is reduced.
When the content of small particles (close to or smaller than the size of the port for discharge) of crushed material is high, or the ratio of the largest block of crushed ore in relation to the size of the feeding port is low The crushing ratio that can be achieved is small which means that the productivity will be improved. If the size of the feed particles is large and the size of the discharge particle is smaller, secondary crushing or multi-stage crushing is often required.
6. The requirements for yield
In order to determine the size of crushing equipment, it is important to determine what the output requirements are. The higher the requirements for output, the larger the size of the crushing equipment required, and the corresponding input and output will rise.
7. Construction site
The most important factor in determining the choice of jaw crusher is the site's specific circumstances. This is the case for the size of the site and the precise placement of the equipment.
