Impact crushers are a common type of crushing equipment. They are widely used in mining, construction, and recycling industries. But different impact crusher models have different capacities and are suitable for different materials. So how do you know which model is right for your needs? This article will help you understand the relationship between impact crusher models, their capacity, and the types of ore they can handle.
It is important to know that the capacity numbers in this article are based on processing limestone under normal conditions. If you are crushing harder materials like granite or iron ore, the actual capacity will be lower. Some manufacturers say that crushing granite or iron ore can reduce capacity by 20 to 30 percent compared to crushing limestone. So you should always check with the equipment manufacturer for accurate numbers based on your specific material.
Common Impact Crusher Models and Their Capacities
There are many different impact crusher series on the market. Some of the most common ones include the PF series, the PFW series, the CI series, and the HPI series from different manufacturers. Each series has multiple models with different specifications.

Suitable Ore Types for Different Impact Crusher Models
Not all impact crushers are good for all types of ore. The hardness and abrasiveness of the material are very important factors. Here is a general guide.
Limestone
Limestone is a medium-hard rock. It is brittle and relatively easy to crush. Most impact crushers can handle limestone well. For small operations processing 50 tons per hour, a compact model like the X50 is suitable. For 100 t/h, the X100 model works well. For 200 t/h, the X200 is a good choice. For 500 t/h, the X500 is designed for large-scale operations.
Luoyang Dahua offers PFQ series impact crushers specifically for limestone. Their models range from PFQ1108 (capacity 50-100 t/h) to PFQ2223 (capacity 850-1200 t/h).
Granite
Granite is a hard and abrasive rock. It has high compressive strength. When crushing granite, the wear parts of the crusher will wear out faster. You need a crusher with a robust design and wear-resistant components. High-chromium hammers are recommended for granite crushing. The capacity for granite will be lower than for limestone using the same machine. Some large-scale impact crushers can process up to 2000 tons per hour or more, depending on the setup.
Iron Ore
Iron ore is also a hard material with high compressive strength. Impact crushers can be used for iron ore crushing, but you need to choose a model with enough power and a strong rotor structure. The CI series is suitable for iron ore processing [15†L7-L8]. The PF/PFV series can also handle iron ore . Just like with granite, the actual capacity when crushing iron ore will be lower than the rated capacity based on limestone.
Other Materials
Impact crushers can also handle many other materials. These include basalt, river pebble, concrete, construction waste, coal, shale, and marble. For each material, the specific model choice depends on the hardness of the material and your target capacity.
How to Choose the Right Impact Crusher Model
When you are trying to figure out which impact crusher model is right for you, here are the main things to think about.
First, know your material. Find out how hard your rock or ore is. Check its compressive strength. Also check if it is very abrasive. Hard, abrasive materials need stronger crushers with better wear parts.
Second, know your capacity needs. How many tons per hour do you need to crush? This will tell you what size of crusher you need. Do not buy a crusher that is too small, because it will not keep up. But also do not buy one that is much bigger than you need, because it will cost more money.
Third, check the feed size. Make sure the crusher’s maximum feed size is larger than the biggest piece of material you will put into it.
Fourth, think about the final product size. Different crushers can produce different output sizes. Make sure the model you choose can give you the size you need.
Fifth, talk to the manufacturer. They can give you specific recommendations based on your material and your needs. They can also tell you what the actual capacity will be for your specific ore.
A Quick Note on Capacity Variations
It is very important to understand that the capacity numbers you see in brochures and on websites are usually based on crushing dry limestone under ideal conditions. If you are crushing granite or iron ore, your actual capacity will be lower. According to industry sources, capacity can be 20 to 30 percent lower for harder materials compared to limestone. So when you are planning your project, make sure to leave some room for this difference. Always ask the manufacturer for capacity estimates based on your specific material.
Conclusion
Different impact crusher models have different capacities and are suitable for different types of ore. Small models like the PF-1007 can handle 15-60 tons per hour. Large models like the HPI 2530 can handle up to 2500 tons per hour. Limestone is easier to crush and gives higher capacity. Granite and iron ore are harder and will reduce the crusher’s capacity. To choose the right model, you need to know your material, your capacity needs, and your feed size. Always check with the equipment manufacturer for accurate information based on your specific situation.
