1. PAINPOINT DRIVEN OPENING

Are inconsistent particle size and premature wear on impact elements causing excessive downstream processing time and unplanned maintenance cycles? When your primary or secondary crushing stage underperforms, the entire operation feels the strain through reduced throughput, higher recirculating loads, and escalating perton processing costs. Key challenges for crushing professionals include:

Unplanned Downtime: Frequent component failure, particularly of blow bars and aprons, halts production. Industry data indicates that for a midsized aggregate plant, each hour of unscheduled downtime can represent over $1,200 in lost revenue and labor.
Inconsistent Product Gradation: Poor control over output size leads to cubicity issues, increasing reject material and failing to meet strict asphalt or concrete mix specifications.
High Operational Costs: Rising energy consumption per ton crushed, combined with the frequent cost of replacement parts and associated labor, directly erodes profit margins.
Rigid Application Fit: Many crushers struggle with varying feed materials—from abrasive granite to recycled concrete—requiring constant adjustment and compromising efficiency.

Is there a crushing solution engineered to deliver predictable performance, reduce total cost of ownership, and maintain specification compliance across diverse materials?

2. PRODUCT OVERVIEW: ISOCertified Horizontal Shaft Impact (HSI) Crushers

This product line comprises a range of ISO 9001:2015 certified horizontal shaft impact crushers designed for primary, secondary, and tertiary reduction of aggregates and industrial minerals. The certification provides documented assurance of consistent design control, manufacturing quality, and traceability—critical for large capital equipment.

Operational Workflow:
1. Feed Entry: Material is directed into the crushing chamber via a reinforced feed hopper.
2. Acceleration & Impact: Feed material is struck by highspeed rotating hammers (blow bars) mounted on a solid rotor assembly and hurled against adjustable primary aprons.
3. Size Reduction & Recirculation: Initial impact fractures the material. Smaller pieces pass through the apron gap setting, while larger pieces are recirculated within the chamber for further impacts against the aprons and other incoming material (rockonrock crushing).
4. Product Control: Final sizing is controlled by the adjustable gap between the primary and secondary aprons, determining the maximum product dimension.
5. Discharge: Correctly sized material exits the chamber onto a discharge conveyor.

Application Scope & Limitations:
Scope: Ideal for natural aggregate (limestone, dolomite), recycled concrete/asphalt (RCA/RA), slag processing, and mediumabrasive industrial minerals. Excels in producing a wellshaped, cubic end product.
Limitations: Not typically recommended as a primary crusher for very hard, highly abrasive igneous rock (e.g., granite, basalt) without significant operational cost considerations. Performance is optimal with feed material within designated hardness and abrasiveness indexes as per factory specifications.
