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 (Цагдаа) 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 (ихэвчлэн хүртэл 1 meter or more in size) into various saleable aggregate products (жишээ нь e., суурь материал, бетон чулуу, асфальт чипс, элс) meeting specific size specifications at a rate of 400 tons every hour.

Үе шатууд & Components in the Schematic:

1. Тэжээлийн хэрэглээ & Холбооны хязгаар:
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.
Grizzly Feeder-ийг чичирч байна (Vgff vgf): Positioned below the hopper. Түүний үндсэн функцууд:
Regulated Feed: Controls the rate of material entering the primary crusher, preventing overload.
Холбооны хязгаар: Removes fine material (often undersized for primary crushing or soil) through its grizzly bars (typically spaced 4-6 инчвэйм / 100-150mm apart). This bypasses the primary crusher, үр ашгийг дээшлүүлэх, элэгдлийг багасгах.
Хамгаалах: Removes very large, non-crushable debris ("трамп металл" can be handled later).

2. Анхдагч бутлах (Coarse Reduction):
Анхдагч crusher: Receives scalped feed from the VGF. For a 400 TPH plant handling hard rock:

Эрүүлийн тусламж: Common choice for its robustness and ability to handle large feed sizes. A large jaw crusher (жишээ нь e., 60" x 89" or similar) with appropriate power is typical.
(Alternative: Grushator crusher): Offers higher capacity potential in a single unit but often has higher capital cost.
Үүрэг: Reduces rock from ~1m down to roughly 6-8 инчвэйм (150-200мм).

3. Хоёрдогч бутлах & Скринингийн гогцоо:
Конвейер (C1): Transports primary crushed material
