Impact Crusher: Designed for Medium-to-Fine Crushing of Brittle Materials

The Henan Ruichi Impact Crusher is a specialized machine developed for medium-to-fine crushing of brittle materials (hardness ≤150 MPa), such as limestone, concrete blocks, and cement clinker. It addresses the three key challenges of traditional crushing equipment: poor finished product shape (excessive needle-like flakes), inadequate wear parts (frequent downtime for replacement), and slow after-sales service. Leveraging a customized rotor forging process (42CrMo monolithic forging for 50% increased impact resistance), wear-resistant blow bar technology (available in high-manganese steel or alloy overlay, with a lifespan of up to 10 months), and a three-stage crushing chamber design (rough impact - collision - shaping, with over 90% cubic particle size), it accurately produces qualified finished products with a particle size of 5-30 mm. Suitable for applications such as producing high-quality aggregates in sand and gravel quarries, on-site recycling of construction waste, and pre-processing cement clinker in building materials factories, it elevates the crushing of brittle materials from inefficient to efficient. "Efficient and Controllable."

1. Core Product Technology: Three Key Highlights Address Crushing Pain Points

The process design of Henan Ruichi impact crusher avoids complex parameters and focuses solely on practical results. Each process addresses a specific crushing problem, ensuring efficient crushing and long-lasting performance.

1. Rotor Technology: Durable and Impact-Resistant, No "Failures" During Crushing

The rotor is the "power heart" of the equipment and is most vulnerable to breakage or vibration during high-speed rotation. Our technology directly addresses these challenges:

Material and Forging: Made of 42CrMo alloy structural steel, it undergoes a "solid-body forging" process and undergoes high-temperature quenching and tempering (850°C quenching + 550°C tempering). This improves fatigue resistance by 50% compared to ordinary cast steel rotors. Even when crushing limestone 24 hours a day, it can provide stable service for 3-5 years.

Vibration-Isolating Structure: The blow bars on the rotor disc are staggered at 15°. This creates a "spiral impact" during rotation, which not only distributes force evenly (resulting in more uniform particle shape) but also reduces vibration. Operating noise is 10 decibels lower than traditional equipment, creating a more comfortable workshop environment.

2. Blow Hammer Technology: Customized to Eliminate Waste and Increase Durability

Blow hammers are consumable parts. The biggest concern is the "inappropriate material, poor durability" or "overpriced, wasteful" design. We customize the technology based on the hardness of the material:

For medium-soft materials (limestone, gypsum): The blow hammers are made of ZGMn13 high-manganese steel. After "water-toughening" (high-temperature heating followed by rapid water quenching), the hardness reaches HB280. They can crush limestone for 6-8 months, offering excellent value.

For medium-hard miscellaneous materials (concrete blocks, sandstone): A 5mm WC alloy layer is welded over the high-manganese steel. Even with small rebar mixed in the material, wear and tear are avoided, extending the service life to 8-10 months, eliminating the need for frequent component replacement and work delays.

3. Crushing Chamber Technology: Three-Stage Design for Excellent Particle Shape and No Sticking

The crushing chamber directly determines the final particle shape. Our "three-stage structure" is specifically designed for brittle materials:

First, roughing: High-speed hammers break up large lumps of material, initially removing sharp edges.

Second, collision: The crushed material is rebounded by the impact plate, where it "grinds" with the incoming material, removing burrs.

Third, shaping: The curved bottom screen plate provides additional gentle pressure and grinding. The resulting product consists of over 90% cubic particles, with ≤3% needle-like flakes, enabling it to be sold directly at premium aggregate prices.

Additional design: The inner wall of the chamber is coated with an anti-stick coating, preventing sticking to the wall when crushing gypsum and cement clinker in humid weather, eliminating the need for frequent machine downtime for cleaning.

2. Three Clear Use Cases: Know at a Glance "Can It Be Used for My Application?"

We don't offer "one-size-fits-all" solutions. Instead, we provide specific process adaptation solutions tailored to the crushing requirements of different brittle materials, allowing you to directly identify the right solution:

1. Premium Limestone Aggregate Scenario: High-quality aggregate for high-speed rail and bridge applications

Adaptive Process: Use "fine crushing chamber + high-manganese steel blow bars + 1200 rpm";

Problem Solved: Traditional equipment crushes limestone, resulting in needle-like flakes and low profit margins. Our equipment produces 5-20mm cubic aggregate, meeting C60 concrete standards;

2. Construction Waste Recycling Scenario: On-site crushing, saving shipping costs and preventing machine jams

Adaptive Process: Use "standard chamber + alloy welded blow bars + elastic impact plates";

Problem Solved: Construction waste mixed with rebar can easily cause machine jams. Our elastic impact plates automatically retract when encountering rebar, immediately resetting after the impurities are expelled, without requiring machine downtime. They can also be integrated into mobile crushing stations for direct crushing at demolition sites;

3. Cement clinker crushing scenario: Avoid over-crushing and save energy.

Suitable process: Use "coarse crushing chamber + high-manganese steel blow bars + 35° impact plate angle."

Problem solution: Over-crushing cement clinker increases grinding energy consumption. Our equipment can precisely control the finished product to 20-30mm, with over-crushed fines ≤5%.

III. Henan Ruichi Exclusive Service: Assisted from selection to operation. The biggest worry when buying equipment is "making the wrong choice and having no one to support you." Our service begins the moment you inquire, helping you avoid pitfalls throughout the entire process:

1. Initial stage: Helping you choose the right process to avoid unnecessary investment.

No need to guess at the model: Simply send your raw materials and we'll test crush them in our test workshop using different processes to determine which solution best meets your particle shape and production capacity requirements.

Providing a customized process sheet: Once you've finalized your solution, we'll provide a detailed process parameter sheet, specifying the chamber type, blow bar material, and speed. We'll even help you plan your production line layout to avoid mistakes later.

2. Mid-term: Helping you "install the equipment and learn how to operate it."

Easy on-site installation: Engineers will provide on-site guidance on foundation pouring and equipment installation, ensuring the rotor rotates without vibration and achieving the desired crushing results.

3. Post-term: Helping you "quickly replace parts and minimize downtime."

No shortages of spare parts: The company maintains three major spare parts warehouses, and wear parts like blow bars and bearings can be shipped within 48 hours.

Quick after-sales response: A 24-hour after-sales hotline resolves common issues the same day.

The Henan Ruichi impact crusher is more than just a "cold machine." Instead, it offers a "technology + service" combination specifically designed for crushing brittle materials. The technology helps you crush high-quality materials, while the service saves you time and money. Whether you're crushing sand and gravel, collecting garbage, or grinding cement, as long as you're crushing brittle materials, this equipment is precisely adapted.
