Gypsum mining in Potiskum, Nigeria, demands efficient crushing and sand-making equipment to transform raw gypsum into high-quality construction aggregates. Below is a tailored production line setup and key equipment recommendations.
1. Primary Crushing: Jaw Crusher (e.g., PE600×900) processes large gypsum blocks (<500mm) into 100–150mm fragments.
2. Secondary Crushing: Impact Crusher (e.g., PF1214) further reduces size to ≤30mm for grinding or sand making.
3. Sand Making: Vertical Shaft Impact Crusher (VSI-1140) produces 0–5mm gypsum sand with adjustable fineness modulus (2.6–3.0).
4. Screening: Vibrating Screen (3YK2160) separates aggregates into 0–5mm, 5–10mm, and 10–30mm grades.
| Equipment | Model | Capacity (t/h) | Power (kW) | Output Size (mm) |
|——————–|———-|—————-|————|——————|
| Jaw Crusher | PE600×900| 50–120 | 75 | 65–160 |
| Impact Crusher | PF1214 | 70–130 | 132 | ≤30 |
| VSI Crusher | VSI-1140 | 60–180 | 250 | 0–5 |
Q1: What’s the moisture tolerance for gypsum crushing?
A: Ideal moisture content should be <10%. For wet gypsum, add a dryer before crushing.
Q2: Can this line produce plaster powder?
A: Yes, integrate a grinding mill (e.g., MTW175) after secondary crushing for 80–325 mesh powder.
A Potiskum-based plant adopted the above line in 2022, achieving:
– Output: 150 t/h of gypsum sand/aggregates.
– Application: Local cement plants and drywall manufacturers.
