Product details

Granalladora industrial de transportador de rodillos KNNJOO de 700 mm para tratamiento superficial continuo (RFQ)

Descripción del producto

La máquina granalladora de paso continuo por rodillos ofrece un rendimiento funcional excelente. El equipo traslada estructuras y piezas de acero hasta la zona de proyección dentro de la cámara de limpieza mediante un sistema de rodillos motorizado de velocidad regulable.

Dentro de la cabina de trabajo, la superficie metálica es impactada y barrida por potentes proyectiles desde múltiples ángulos, eliminando completamente la escama de óxido, capa de corrosión y manchas superficiales. Después del tratamiento, la pieza adquiere una superficie más lisa y uniforme. Las piezas finalizadas se descargan a través de los túneles de entrada y salida situados en ambos lados del equipo.

Esta máquina está diseñada principalmente para la limpieza y el endurecimiento superficial de soldaduras de estructuras de acero, vigas H, chapas de acero y otros componentes metálicos. Se utiliza ampliamente en industrias de automoción, tractores, motores y válvulas.

Gracias a su capacidad de limpieza rápida y eficaz, mejora el acabado superficial de las piezas y optimiza la adherencia y calidad del recubrimiento posterior, siendo una solución muy demandada en el sector de procesamiento de piezas industriales.

Tras el proceso de granallado realizado por el dispositivo de limpieza de granallas, la pieza de trabajo aún puede quedar cubierta por granallas, las cuales deben eliminarse. La herramienta de limpieza es un cepillo giratorio fijado de forma rígida sobre un portacepillo intercambiable.

Dispositivo de limpieza de granallas

Para evitar el impacto de granallas sobre piezas largas, el cepillo giratorio retira suavemente el abrasivo usado de la superficie de la pieza y lo arrastra hacia una ranura de diseño especial. La ranura dispone de un transportador de tornillo que devuelve el medio abrasivo para su reciclaje. Con el fin de mantener estable la posición del cepillo y el transportador de tornillo al procesar piezas de diferentes tamaños, ambos componentes se montan sobre un mismo bastidor regulable. El bastidor puede ajustarse manual o automáticamente dentro del rango de altura requerido, y el margen de ajuste debe ser inferior a 5 mm. Finalmente, los restos de abrasivo sobre la pieza son eliminados mediante un soplador instalado también en el bastidor, el cual emplea un ventilador de alta presión para expulsar el material residual.

Carga y descarga

En la configuración estándar del equipo, la entrada y salida del transportador de rodillos son accionadas por el grupo motriz central de la granalladora. Para aumentar la eficiencia, se puede instalar una unidad de accionamiento independiente con variador de frecuencia integrado, que realiza la sincronización automática.

Si tras el granallado las piezas curvas no quedan completamente limpiadas por el cepillo giratorio y el sistema de soplado, se recomienda emplear una vía de recogida y un transportador de reciclaje más largos, para garantizar que las granallas sean recuperadas por el equipo.

La instalación de un sistema de avance horizontal permite mejorar la eficiencia en múltiples aspectos. Este sistema puede integrarse junto con la granalladora en líneas de producción de aserrado y taladrado. La mayoría de granalladoras de transportador de rodillos utilizan granallas esféricas (granalla de acero fundido o granalla cortada redondeada). Las granallas circulan por el interior del equipo y eliminan continuamente los agentes contaminantes.

Para obtener un resultado de granallado óptimo, es indispensable mantener una mezcla equilibrada entre granallas nuevas y usadas. Las granallas finas de la mezcla aseguran una cobertura uniforme sobre la pieza, mientras que las granallas gruesas son fundamentales para eliminar la escama de óxido. La selección adecuada del tipo de granalla resulta decisiva para garantizar un buen resultado del proceso de granallado.

Guía de uso de granallas

  • Piezas con mecanizado rugoso (perfiles de chapa gruesa): utilizar mezcla de granalla gruesa (granalla de acero tamaño S390 o superior).

  • Piezas con acabado superficial (chapas metálicas delgadas): utilizar mezcla de granalla fina (granalla de acero tamaño S330 o inferior).

Q: Is the forklift industry ushering in a "super cycle"?

A: The industry data just released is too explosive! In October 2025, forklift sales 114,300 units, domestic and foreign sales soared by double digits (domestic sales + 16.2%, export sales + 15.4%), and the cumulative sales from January to October exceeded 1.22 million units, surging 14.2% year-on-year! On the one hand, JD.com spent 100 billion to purchase 3 million logistics robots, and on the other hand, hydrogen forklifts single order surged 108 units. The forklift industry is experiencing a "green + intelligent" dual revolution. These changes!

Q: How does a smart forklift work?

A: Have you seen how a smart forklift works? Recently, CCTV news came to Hefei and walked into the intelligent workshop of Anhui Forklift Group. Let's follow the camera. This 67-year-old enterprise is on a path of transforming and upgrading traditional industries and developing new quality productivity. Now I have come to the debugging and testing area of the mobile robot. More than a dozen cars behind me are conducting sensor calibration and basic function testing here. I am now standing on its forward path. In the eyes of the robot, I am an obstacle, and it will automatically stop.

Q: Smart Forklift "Create a new model of safety supervision?

A: According to the staff of Xinhe Food, the system integrates a number of intelligent management functions, and builds a comprehensive protection system through comprehensive digital control of personnel, vehicles and behaviors. The personnel management module realizes the digitization of the driver's account and real-time early warning; the vehicle positioning function ensures the safe operation of the forklift in the electronic fence; the operation early warning actively reminds to fasten the seat belt; the identification mechanism strictly restricts only the filing personnel to operate the vehicle, fundamentally eliminating unlicensed driving. At the same time, the system also has data analytics capabilities to provide reliable data support for vehicle scheduling and performance mangement.
