1. KHAI THÁC ĐIỀU KHIỂN PAINPOINT

Bạn đang quản lý các hoạt động nghiền nơi mà độ tin cậy của thiết bị, phân loại sản phẩm nhất quán, and total cost of ownership directly determine profitability? Dành cho người quản lý nhà máy và nhà thầu kỹ thuật, the challenges with primary crushing are quantifiable. Unplanned downtime for mantle or concave replacement can halt an entire processing line, gây thiệt hại hàng chục nghìn mỗi giờ trong sản xuất bị mất. Inconsistent feed size or moisture content can lead to choking, giảm thông lượng và tăng mức tiêu thụ điện năng trên mỗi tấn. Hơn nữa, the global push for responsible manufacturing means sourcing equipment that complies with environmental directives like RoHS is no longer optional but a prerequisite for many projects and tenders.

How do you achieve higher availability with lower maintenance labor? Can your primary crusher deliver a consistent product curve despite variable feed? Are your equipment partners providing verifiable compliance documentation for hazardous substance control? The solution lies in specifying a Máy nghiền con quay tuân thủ RoHS from a manufacturer committed to both performance and material integrity.

2. TỔNG QUAN SẢN PHẨM

MỘT Máy nghiền con quay tuân thủ RoHS is a primary crushing machine designed for highcapacity, continuous operation in largescale mining and aggregate operations, built with strict adherence to the Restriction of Hazardous Substances (RoHS) chỉ thị. This governs the use of specific hazardous materials in electrical components and certain mechanical alloys.

Quy trình hoạt động:
1. Lượng thức ăn ăn vào: Large runofmine ore or quarry rock is directly dumped into the crusher’s receiving hopper above the spider assembly.
2. hành động nghiền nát: The gyrating mantle eccentrically compresses material against the stationary concave liners, applying progressive compressive force to break particles.
3. Phóng điện: Crushed material falls by gravity through the decreasing gap at the bottom of the chamber and exits through the discharge opening.

Phạm vi ứng dụng: Lý tưởng cho tải trọng cao (1,500+ tph) primary crushing stations handling abrasive ores (sắt, đồng, vàng) và đá cứng. It is the preferred solution for slabby feed material due to its nonchoking design.

Hạn chế: Higher capital cost compared to jaw crushers; requires a substantial and stable foundation due to weight and dynamic forces; not suitable for portable plants or lowtonnage operations.
