1. APERTURA IMPULSADA POR EL PUNTO DE DOLOR

Are you managing unpredictable aggregate specifications, costos excesivos de piezas de desgaste, and unplanned downtime in your secondary reduction or recycling operations? Inconsistent product gradation leads to rejected loads and lost revenue. Frequent rotor or liner replacement halts production for maintenance, costando miles por hora en rendimiento perdido. High vibration levels and tramp metal events risk catastrophic damage to your custom impact crushers, resulting in repair bills that erase quarterly profit margins.

What if your crushing circuit could deliver a more consistent product shape with lower operating costs? Is it possible to extend service intervals while simplifying maintenance access? Can an impact crusher be engineered to protect itself from uncrushables, maximizing uptime? The solution lies not in standard models, but in precisionengineered custom impact crushers designed for your specific material and output goals.

2. DESCRIPCIÓN GENERAL DEL PRODUCTO: CUSTOM IMPACT CRUSHERS

A custom impact crusher is a heavyduty comminution machine engineered for specific feed materials and product requirements beyond the scope of standard OEM models. It utilizes kinetic energy where fitted hammers or blow bars on a highspeed rotor strike the incoming feed, throwing it against adjustable aprons or breaker plates for controlled fragmentation.

Flujo de trabajo operativo:
1. Consumo de alimento: Targeted feed material (p.ej., hormigón reciclado, caliza, escoria) is directed into the robust feed hopper.
2. Aceleración & Impacto: Material enters the crushing chamber and is struck by rotating blow bars on the customconfigured rotor, accelerating it towards the impact surfaces.
3. Controlled Fragmentation: The accelerated material impacts the adjustable primary and secondary aprons (or breaker plates), fracturing along natural grain boundaries.
4. Apresto & Recirculación: Sized material passes through the gap between the rotor and aprons. Oversize can be recirculated via a closed circuit with a screen or further processed.
5. Descarga del producto: Crushed product is discharged onto a conveyor system for downstream processing.

Ámbito de aplicación: Ideal for secondary, terciario, etapas de trituracion y cuaternaria; reciclaje (do&Residuos, asfalto); processing of mediumhard to hard, Materiales no abrasivos a moderadamente abrasivos.; applications requiring precise control over product cubicity.

Limitaciones clave: Not typically suitable for primary crushing of very large feed sizes or for highly abrasive materials (where cone crushers may be preferred) without specific alloy customization and accepted wear cost profiles.
