Complete Guide to Choosing the Right Jaw Crusher

Selecting the right jaw crusher is critical for the success of your mining, quarrying, or construction project. As the primary crushing equipment, a well-chosen jaw crusher will maximize your production efficiency, reduce operating costs, and minimize downtime—while a poor choice can lead to wasted investment, low output, and frequent maintenance headaches.

At Chunlei Machinery, a leading manufacturer of mining crushing equipment with 30+ years of experience, we’ve helped thousands of global customers choose the perfect jaw crusher for their unique needs. In this complete guide, we’ll break down the key factors to consider when choosing a jaw crusher, from feed size and material hardness to mobile vs stationary options, and share our top-recommended models to help you make an informed decision.

Key Factors When Choosing Jaw Crusher

Before determining specific details such as feed size or mobility, first identify the key factors for selecting a jaw crusher. These factors influence the equipment’s performance, cost-effectiveness, and service life. An error in any one of these factors could result in the jaw crusher failing to meet the project’s requirements—therefore, be sure to take the time to carefully evaluate each factor:

- Project and Production Requirements: Do you need small-scale crushing (5–50 tons per hour) or large-scale production (100–800 tons per hour)? Will the jaw crusher be used solely for primary crushing, or as part of a complete production line? Clarifying your production goals will help narrow down your choice of models.
- Material Characteristics: The type and hardness of the material to be crushed (e.g., limestone, granite, ore) will determine the jaw crusher’s design, jaw plate material, and the required crushing force.
- Space and Installation Constraints: Is space limited at your construction site? Will the jaw crusher be installed in a fixed location, or will it need to be moved frequently?
- Budget and Long-Term Costs: While upfront costs are important, you should also consider long-term expenses such as maintenance, replacement of wear parts, and energy consumption—these costs can add up to a significant amount over time.
- After-Sales Service: Choose a manufacturer that provides reliable after-sales service, technical support, and spare parts—this is crucial for minimizing downtime when the jaw crusher requires maintenance. Chunlei Machinery offers a full range of services.

At Chunlei Machinery, we start every customer consultation by evaluating these key factors to ensure we recommend a jaw crusher that aligns with their project’s unique requirements—no one-size-fits-all solutions.

Feed Size & Capacity Requirements

Feed size and capacity are two of the most important technical specifications to consider when choosing a jaw crusher. They directly determine whether the equipment can handle your raw materials and meet your production targets.

How to Determine Feed Size

Feed size refers to the maximum size of raw material that a jaw crusher can process. To determine this size, you need to measure the largest rock or material block you intend to crush—the jaw crusher’s feed hopper and crushing chamber must be large enough to accommodate these blocks without causing a jam.

Example: If your feed material includes rock blocks with a diameter of up to 1,200 mm, you will need a jaw crusher with a maximum feed size of at least 1,200 mm (we recommend adding a 10–15% margin to prevent jamming). Chunlei’s jaw crushers offer a feed size range from 100 mm to 1,500 mm, capable of meeting the needs of projects of all sizes.

How to Choose the Right Capacity

Capacity (measured in TPH, or tons per hour) is the amount of material the jaw crusher can process in one hour. Your capacity needs depend on your project’s daily production targets, working hours, and downstream processing requirements (e.g., secondary crushing, sand making).

Key Tips for Capacity Selection:

Calculate your daily production target, then divide by your working hours to get your required TPH (e.g., 500 tons per day ÷ 8 hours = 62.5 TPH).
Choose a jaw crusher with a capacity slightly higher than your required TPH (10-20% buffer) to account for material variations and unexpected downtime.
Chunlei’s jaw crushers offer capacities from 5 TPH (small-scale) to 800 TPH (large-scale mining), with customizable options to match your exact needs.

Hardness of Material

The hardness of the material you’re crushing is a critical factor that determines the type of jaw crusher, jaw plate material, and crushing force required. Jaw crushers are designed to handle different material hardness levels—choosing the wrong one will lead to premature wear, low output, and increased maintenance costs.

Material Hardness Classification & Jaw Crusher Selection

Materials are typically classified by their compressive strength (measured in MPa). Here’s how to match your material to the right jaw crusher:

1. Stationary Stone Crusher Plant
- Best For: Large-scale, long-term projects (e.g., 5+ years) with a fixed site.
- Pros: Higher capacity, lower cost per ton, easier maintenance access.
- Cons: Requires significant civil work, immobile.
2. Semi-Mobile (Skid-Mounted) Plant
- Best For: Medium-term projects where the site may change every 2-3 years.
- Pros: Reduced foundation work, can be relocated as a unit.
- Cons: Lower maximum capacity than stationary plants.
3. Fully Mobile Wheeled or Tracked Plant
- Best For: Multiple sites, rental fleets, or projects needing to move with the mining face.
- Pros: On-site mobility, eliminates material hauling costs, quick setup.
- Cons: Higher operating cost per ton, lower overall capacity, more complex maintenance.

Step-by-Step Setup of a Stone Crushing Plant

Setting up a plant involves a logical sequence of steps. Proper planning here prevents costly bottlenecks later.

Soft Materials (Compressive Strength < 100 MPa): Examples include limestone, dolomite, and clay. A standard jaw crusher with mild steel jaw plates is sufficient—these materials are easy to crush and cause minimal wear.
Medium-Hard Materials (100-200 MPa): Examples include sandstone, shale, and coal. A jaw crusher with wear-resistant alloy steel jaw plates is recommended to handle moderate wear and maintain efficiency.
Hard Materials (200-320 MPa): Examples include granite, basalt, iron ore, and copper ore. You’ll need a heavy-duty jaw crusher with high crushing force, thick alloy steel jaw plates, and a reinforced frame—like Chunlei’s CJ Series European Jaw Crusher, which is engineered for hard rock crushing.

Pro Tip: If you’re unsure about your material’s hardness, send a sample to Chunlei Machinery—we can test it for you and recommend the perfect jaw crusher model.

Mobile vs Stationary

Another key decision when choosing a jaw crusher is whether to opt for a stationary or mobile model. Both have unique advantages and are suited for different project scenarios—your choice will depend on your job site location, mobility needs, and space constraints.

Stationary Jaw Crushers

Stationary jaw crushers are installed in a fixed location (e.g., a quarry or mining site) and are ideal for long-term, large-scale projects. They offer higher capacity, lower energy consumption, and easier maintenance compared to mobile models.

Best For: Large quarries, mining operations, and fixed crushing plants where raw material is concentrated in one location. Chunlei’s stationary jaw crushers are available in various sizes and capacities, and can be integrated into complete crushing lines with cone crushers, impact crushers, and vibrating screens.

Mobile Jaw Crushers

Mobile jaw crushers (wheeled or crawler) are portable and can be moved directly to the job site—eliminating the need for material transportation and reducing costs. They are compact, easy to install, and ideal for on-site crushing.

Best For: Construction waste recycling, road and bridge construction, small quarries, and projects where material is scattered across multiple locations. Chunlei’s mobile jaw crushers are available in wheeled and crawler models, with capacities from 10 TPH to 200 TPH—perfect for on-the-go crushing.

How to Choose Between Mobile & Stationary

First, consider the following questions:

Do you need to move the crusher between different job sites?
Are your raw materials located in different places?
Is installation space limited?

If your answer to any of the above questions is yes, then a mobile jaw crusher would be the better choice. For long-term projects at fixed locations, a stationary jaw crusher will offer higher efficiency and lower long-term costs.
