Key features

Versatile Crushing Cavity: Interchangeable impact liners adapt to coarse and fine crushing to produce well-graded cubical aggregates.

Quick Wear Part Replacement: Simplified bolt-free mounting cuts downtime; crews swap liners without heavy auxiliary tools.

Up to 35% Higher Throughput: Optimized rotor speed and blow bar geometry boost hourly output against conventional crushing units.

Stable Heavy-Duty Operation: Reinforced rotor assembly maintains consistent performance in quarry rock and construction waste recycling sites.

Superior Particle Shape Control: Produces uniformly cubed finished material with fewer flat and elongated fragments than compression-type crushing equipment.

AI-Powered supplier vetting

SummaryThe supplier is identified as a factory and professional technical supplier for crushing and screening equipment, with stated R&D experience, 3D software design, ODM, OEM, and broad customization capabilities. It reports inventory capability, offices in major Chinese cities, an international marketing department, export coverage across multiple regions, and after-sales service experience. Service-related corrective action and complaint-handling procedures are documented and followed, although the assessment procedure itself lacks a written procedure. The supplier has no available SDK, no new products in the past year, no overseas warehouse or showroom, and several sustainability-related statuses are unknown. Financial information is represented only by reporting years, without sufficient evidence to assess financial credibility.

Supplier typeThe supplier is explicitly identified as a factory in Shanghai's Fengxian District and is described as a major Chinese producer and export base for gravel and sand production equipment. Its stated business includes crushing and screening equipment and systems, supported by an international marketing department.

After-Sales capabilityThe supplier states that it has a complete after-sales service system, provides timely service through offices in major Chinese cities, and has experienced design engineers. It also has clear, followed procedures for corrective and preventive actions and customer complaints, although its service-capability assessment procedure has records without a written procedure.

Production capacityThe supplier is identified as a factory and as a producer of gravel, sand, crushing, and screening equipment, with stated production processes and inventory capability. Its valid manufacturing contract status is unknown, so the available evidence supports production capability but does not establish the completeness of its manufacturing documentation.

Customization capabilityThe supplier explicitly provides customization from samples, customization from designs, full customization, minor customization, and flexible customization. It also offers 3D software design, ODM, and OEM services, providing strong direct evidence of broad customization capability.

Client casesThe supplier states that its products are used across Southeast Asia, the Middle East, Africa, Europe, and other regions, with customer praise, and that it provides OEM services for well-known brands. These statements indicate international market exposure and brand-related service experience, although no specific customer names or project case details are provided.

Product Q&A

Q:What types of materials can this unit process?

It handles medium and low hardness rock such as limestone, basalt, granite, and recycled construction waste for aggregate production.

Q:Can it produce finished sand and high-quality cubical aggregates?

Yes. The impact crushing principle delivers uniformly cubed particles, ideal for road and concrete aggregates.

Q:How often do blow bars and impact plates need to be replaced?

Service life depends on material hardness. Wear parts inspection is recommended daily; spare wear components should be kept on-site for quick replacement.

Q:Is it suitable for primary crushing or only secondary crushing?

Models are available for secondary and tertiary crushing. It is not recommended for extremely hard, highly abrasive raw ore.

Q:How to adjust the output particle size?

Finished size can be modified by adjusting the gap between impact plates and the rotor. Rotor speed adjustment is also optional on certain versions.
