EQJ-100 Jaw Crusher

Compact and Safe: Anti-Rebound Feed Hopper

The EQJ-100 is designed for standard laboratory environments. It handles samples up to 50 mm and reduces them below 1 mm. Intuitive to use, low maintenance.

⚙
Eccentric Shaft — Elliptical Motion
The 1.5 HP eccentric shaft creates an elliptical motion between the fixed and movable jaws, maximizing crushing efficiency.
🛡
Anti-Rebound Feed Hopper
Prevents material from bouncing out of the crushing chamber. Safe sample feeding is possible while the machine is running.
📏
Analog Gap Adjustment
The analog indicator on the left side allows easy adjustment of the jaw gap and final output size.

EQJ-200 Jaw Crusher

Industrial Scale: 110 mm Feed, 5 kg/min Throughput

The EQJ-200 is a heavy-duty model for high-throughput facilities. It accepts samples up to 110 mm and processes up to 5 kg per minute in continuous operation.

🔩
Manganese Steel Jaws
Crushes the hardest ferro-alloys — including refined FeCr — without jaw wear. Manganese steel is the industry standard for abrasion resistance in mining.
⚡
4,000 W Three-Phase Motor
No motor stalling even on the toughest samples. Maximum power: 4,500 W.
📦
6.8-Litre Collection Bin
Large-volume collector for uninterrupted continuous operation. Dimensions: 138 × 90 × 58 cm (H × W × D), weight 550 kg.

Frequently Asked Questions

What You Wonder About

Usually no. Jaw crushers perform primary size reduction only. Before analysis on instruments such as XRF or XRD spectrometers, the crushed output (1 mm to 10 mm) must be further reduced to micron level (<45 µm) using a disc mill (e.g. EQR-200) or a ball mill.

The EQJ-100 is a compact bench-top model for standard laboratory use; it processes samples up to 50 mm in batch mode. The EQJ-200 is a heavy-duty industrial model designed for high-throughput facilities: it accepts feed up to 110 mm and delivers continuous throughput of up to 5 kg per minute.

No. The purpose-designed anti-rebound feed hopper prevents material from ejecting out of the crushing chamber. Safe sample feeding is possible even while the machine is in operation.

No. The EQJ-200 jaws are made from manganese steel, the standard wear-resistant material in the mining industry. Even extremely hard ferro-alloys such as refined FeCr can be crushed without damaging the jaws.
