69 Jaw Crusher with What Size Motor? What Size Secondary Jaw Crusher? What Size Impact Crusher?
The 69 jaw crusher, often designated as the PE600x900 model, is a robust primary crushing equipment widely used in mining, quarrying, and construction industries. It features a feed opening of 600mm by 900mm, designed to handle hard rocks and ores by compressing them between a fixed and movable jaw plate. The motor is the powerhouse that drives the eccentric shaft, enabling the jaw’s toggling motion for crushing. A secondary jaw crusher, typically smaller like the PE250x400 or PE400x600, follows the primary unit to further reduce particle sizes for finer processing. An impact crusher, such as the PF series, uses high-speed rotors and impact plates to shatter materials through kinetic energy, often serving as a tertiary stage for producing cubical aggregates.
One common question is: What factors influence the motor size for a 69 jaw crusher? The answer lies in the crusher’s power requirements, which depend on material hardness, feed size, and desired output capacity—typically ranging from 55kW to 75kW to ensure optimal performance without overload. Another frequent query: How does the size of the secondary jaw crusher affect overall efficiency? It must be matched to handle the output from the primary crusher, usually 1/3 to 1/2 the size, to prevent bottlenecks and maintain a smooth flow in the production line.
Properly configuring a 69 jaw crusher with the right motor, secondary jaw crusher, and impact crusher offers several advantages. It enhances energy efficiency by avoiding underpowered or oversized components that waste electricity. Equipment longevity improves as matched sizes reduce wear and tear on parts like belts and bearings. Production output increases with seamless material flow, minimizing downtime and boosting throughput by up to 20-30% in optimized setups. Safety is also elevated, as balanced configurations prevent vibrations or imbalances that could lead to accidents.
To configure this setup effectively, follow these detailed steps. First, evaluate your raw material properties, including hardness, size, and required final product specifications, along with target hourly capacity (e.g., 50-100 tons for a standard 69 jaw crusher). Use a production line flowchart to map out the process. As illustrated in the flowchart below, which outlines the sequence from primary to tertiary crushing:
Flow Chart of Stone Production Line
Next, select the motor for the 69 jaw crusher based on power calculations—commonly 55-75kW for standard operations. Install it by aligning the motor base with the crusher frame, securing with bolts, and connecting via V-belts to the flywheel. Refer to the installation guide shown here for precise alignment to avoid belt slippage:

In the mining and construction industries, crushers play a crucial role in breaking down large materials into smaller, more manageable sizes. To understand the differences between a heavy hammer crusher and a jaw crusher, it’s essential to break down their core concepts, including design, functionality, and applications.
A jaw crusher, also known as a toggle crusher, is a robust machine primarily used for primary crushing. It operates by compressing materials between two plates: a fixed jaw and a movable jaw that swings back and forth. This motion creates a V-shaped cavity where rocks are fed from the top and gradually crushed as they move downward. Jaw crushers are typically built with heavy-duty steel frames to withstand high pressure and are ideal for handling hard, abrasive materials like granite or ore. Their discharge size is adjustable via the gap between the jaws, allowing for control over the final product size.
On the other hand, a heavy hammer crusher is an impact-based machine designed for efficient, one-stage crushing. It features a large rotor equipped with heavy hammers that rotate at high speeds, striking and shattering materials upon impact. The structure includes a sturdy casing, a feeding inlet, and a discharge outlet with grates to control particle size. Unlike jaw crushers, heavy hammer crushers excel in processing medium-hard materials such as limestone, coal, or gypsum, where the impact force can achieve finer reduction in a single pass. This design emphasizes kinetic energy over compression, leading to higher throughput in certain scenarios.
What are some common questions about the differences between heavy hammer crushers and jaw crushers? One frequent query is: Which one is better for primary crushing of very hard rocks? Jaw crushers are generally superior for this purpose because their compressive mechanism can handle tougher, more abrasive materials without excessive wear, whereas heavy hammer crushers might experience faster hammer degradation on extremely hard substances. Another common question is: How do their energy consumption levels compare? Jaw crushers tend to be more energy-efficient for coarse crushing due to their slower operation and focused force application, while heavy hammer crushers consume more power but offer faster processing for softer materials, potentially balancing out in overall operational costs.
Knowing the distinctions between these two crushers provides several advantages. First, it enables better equipment selection tailored to specific material types and project needs, which can significantly enhance productivity and reduce downtime. For instance, choosing the right crusher minimizes unnecessary wear on parts, extending machine lifespan and lowering maintenance expenses. Additionally, understanding these differences optimizes the crushing process, leading to improved product quality—such as more uniform particle shapes—which is vital for downstream applications like concrete production or road construction. Overall, this knowledge helps in achieving cost savings, environmental benefits through efficient resource use, and safer operations by matching machinery to workload demands.
To effectively distinguish between a heavy hammer crusher and a jaw crusher in practice, follow these detailed steps. Start by examining the external structure and components. Look at the machine’s frame and key parts: a jaw crusher will have prominent jaw plates forming a V-shape, while a heavy hammer crusher features a cylindrical rotor housing with access panels for hammers.

In contrast, a heavy hammer crusher relies on a high-speed rotor where hammers swing freely to impact and break down feed material.
Hammer Crusher Working Principle in animation
Then, test or simulate the crushing process with sample materials. Feed a hard rock into each and compare the output: jaw crushers produce more elongated particles, whereas heavy hammer crushers yield cubical shapes due to multiple impacts.
Difference Between Hammer Crusher vs Jaw Crusher
Finally, evaluate performance metrics like throughput and energy use under similar conditions to quantify differences, ensuring you select based on your specific requirements.
In real-world applications, these differences manifest in tangible results. For example, in a limestone quarry project, switching from a jaw crusher to a heavy hammer crusher reduced processing stages from two to one, increasing daily output by 30% and cutting energy costs by 15%. In another case involving granite mining, using a jaw crusher for primary reduction prevented excessive wear that a heavy hammer model would have suffered, extending equipment life by over 20% and avoiding frequent downtime. Lastly, a construction aggregate plant reported improved product quality with a heavy hammer crusher on softer stones, resulting in 25% better sales due to more uniform particle shapes that enhanced concrete strength.

Breaking Down the Concept of Small Mobile Crushers and Their Hourly Capacity
A small mobile crusher is a compact, portable machine designed for on-site crushing of materials like rocks, concrete, asphalt, and aggregates. Unlike larger stationary crushers, these units are mounted on tracks or wheels, allowing easy transportation and setup at various job sites, such as construction zones, quarries, or recycling facilities. The “small” designation typically refers to models with lower power requirements and smaller feed openings, making them ideal for limited spaces or smaller-scale operations.
Key components include a jaw, impact, or cone crusher mechanism, a hopper for feeding materials, conveyor belts for output, and often screens for sorting crushed products. The hourly crushing capacity—measured in tons per hour (TPH)—varies based on the machine’s design, but for small models, it generally ranges from 10 to 90 TPH. This capacity depends on factors like the type of material being crushed (e.g., soft limestone vs. hard granite), input size, moisture content, and operational efficiency. For instance, entry-level small mobile jaw crushers might handle 10-30 TPH for softer materials, while more robust compact units can reach up to 90 TPH for concrete recycling. Understanding this breakdown helps operators select the right equipment to match project demands without over- or under-investing.
