The Engineered Flow: Schematic of a 400 TPH Rock Crushing Plant

Processing raw rock into precisely sized aggregates demands a sophisticated and efficient system. A schematic diagram for a 400-ton-per-hour (TPH) rock crushing plant provides the essential blueprint for understanding the sequence of operations, equipment interconnections, and material flow necessary to achieve this high-capacity output reliably. This article outlines the typical components and flow depicted in such a schematic.

Core Objective: Transform large blasted rock (thường lên tới 1 meter or more in size) into various saleable aggregate products (ví dụ., vật liệu cơ bản, concrete stone, asphalt chips, cát) meeting specific size specifications at a rate of 400 tons every hour.

Giai đoạn & Components in the Schematic:

1. Lượng thức ăn ăn vào & Scalping:
Primary Dump Hopper: Large blasted rock is dumped by haul trucks into a robust, reinforced concrete or steel hopper. Capacity is designed to buffer surges in truck deliveries.
Bộ nạp Grizzly rung (VGFF VGF): Positioned below the hopper. Its primary functions are:
Regulated Feed: Controls the rate of material entering the primary crusher, preventing overload.
Scalping: Removes fine material (often undersized for primary crushing or soil) through its grizzly bars (typically spaced 4-6 inch / 100-150mm apart). This bypasses the primary crusher, nâng cao hiệu quả và giảm hao mòn.
Sự bảo vệ: Removes very large, non-crushable debris ("kim loại lang thang" can be handled later).

2. Nghiền sơ cấp (Giảm thô):
Máy nghiền sơ cấp: Receives scalped feed from the VGF. For a 400 TPH plant handling hard rock:

lời nguyền hàm: Common choice for its robustness and ability to handle large feed sizes. A large jaw crusher (ví dụ., 60" x 89" or similar) with appropriate power is typical.
(Thay thế: Máy nghiền hồi chuyển): Offers higher capacity potential in a single unit but often has higher capital cost.
Chức năng: Reduces rock from ~1m down to roughly 6-8 inch (150-200mm).

3. Nghiền thứ cấp & Screening Loop:
Conveyor (C1): Transports primary crushed material
