Selecting the correct horsepower (HP) for an aggregate conveyor is critical for efficient material handling in crushing and screening plants. Key factors include conveyor length, belt speed, material density, and incline angle.
Calculation Formula:
HP = (Te × V) / 33,000
– Te: Effective belt tension (lbs)
– V: Belt speed (ft/min)
A typical aggregate production line includes:
1. Primary Crusher: Jaw crusher (e.g., Feed size: ≤1,200mm, Capacity: 50–800 TPH)
2. Secondary Crusher: Cone crusher (e.g., Output: 20–300mm, HP: 200–500)
3. Tertiary Crusher: VSI crusher for sand shaping (e.g., Capacity: 60–500 TPH)
4. Vibrating Screens: Multi-deck screens (e.g., Size: 3–6m², Power: 5–30 kW)
| Equipment | Model | Power (HP) | Capacity (TPH) |
|---|---|---|---|
| Jaw Crusher | PE-750×1060 | 110 | 110–250 |
| Cone Crusher | HPT-300 | 300 | 150–350 |
| Belt Conveyor | B800×20m | 15 | 200–400 |
Q1: How to reduce conveyor power consumption?
A: Optimize belt tension, use energy-efficient motors, and minimize incline angles.
Q2: What’s the lifespan of crusher liners?
A: Typically 3–6 months, depending on material abrasiveness (e.g., granite vs. limestone).
