Hydraulic press for used paper: specifications, certifications and purchase criteria for waste pickers
Hydraulic Press for Waste Paper: Specifications, Certifications, and Buying Criteria for Recyclers
In the recycling industry, efficient compaction of waste paper is key to reducing logistics costs and optimizing storage space. A hydraulic press for waste paper is the central equipment in recycling centers, waste treatment plants, and paper mills. This article describes technical specifications, available certifications, and decision criteria for acquiring a vertical or horizontal hydraulic baler, based on verified manufacturer data and European regulations.
Problem: Volume and Storage Costs of Waste Paper
Waste paper, whether cardboard, newspapers, magazines, or cuttings, occupies a large volume if not compacted. Without a hydraulic press, recycling centers face high transport costs (up to 30% more according to documented cases) and fire risks from loose accumulation. The solution is a baler that reduces the material into dense, uniform bales.
Industrial Context: Types of Balers for Waste Paper
There are two main configurations: vertical balers (models like NK1070T60) for small to medium volumes, and automatic horizontal balers (NKW series) for high capacities. NKBALER, a company based in Wuxi, China, founded in 2013 with a 50,000 m² plant, manufactures both types with carbon steel structure.
Detailed Solution: Key Models and Specifications

- Feed opening: 1100 x 500 mm
- Capacity: 5-8 bales/hour
- Customizable voltage: 380 V/50 Hz
- Motor power: 15 kW / 20 HP

Automatic Horizontal Baler NKW180QT
For high-volume recycling plants, the fully automatic horizontal hydraulic baler model NKW180QT offers higher productivity. According to the manufacturer:
- Fully automatic with main motor of 45 kW + 7.5 kW
- Main cylinder force: 180 tons
- Working pressure: 30.5 MPa
- Bale dimensions: 1100 mm (width) × 1250 mm (height) × ~1600 mm (length)
- Material density: 500-600 kg/m³
- Feed opening: 2000 mm × 1100 mm
- Capacity: 12-15 tons/hour
- Main structure weight: 28 tons
- Conveyor belt: 12 m x 2000 mm
- Material: carbon steel
Step-by-Step: Compaction Process of Waste Paper
- Feeding: Waste paper is deposited into the hopper via conveyor belt or manually.
- Compression: The hydraulic cylinder applies pressure (up to 60 T for vertical or 180 T for horizontal) to compact the material.
- Bale formation: The machine forms a bale with specific dimensions (e.g., 1100 x 700 x 500 mm for NK1070T60).
- Tying: Wires (5 units, gauge 6#/8# in horizontal models) are placed to secure the bale.
- Ejection: The finished bale is ejected automatically (in horizontal models) or manually (in vertical).
Real Use Cases
According to manufacturer data, a client in Indonesia (a recycling station manufacturer) uses an automatic horizontal baler for plastic waste and paper. The machine operates stably for 10-15 years, with low noise and low energy consumption. Another case in Romania reported that alfalfa bale density exceeded 400 kg/m³ after installation, reducing transport costs by approximately 30%.

Frequently Asked Questions (FAQ)
1. What certifications does a NKBALER hydraulic press for waste paper have?
The horizontal hydraulic baler model NKW180QT has the VERIFICATION OF CONFORMITY certificate number DPWD/09/060/2024, issued by the Executive Director, applicable to the EU/EEA market. Applicable standards are EN ISO 12100:2010, EN 60204-1:2018, and EN 415-1:2014. Additionally, other horizontal balers are certified according to the Machinery Directive with number EASY03220201M, issued by UDEM International Certification Auditing Training Centre Industry and Trade Inc. Co., for the European Union, European Economic Area, and Turkey, in accordance with EN ISO 12100:2010 and EN 60204-1:2018.
2. What is the production capacity of a vertical baler for waste paper?
The vertical baler model NK1070T60 produces 5 to 8 bales per hour, with bale weight varying depending on the density of the waste paper. Each bale measures approximately 1100 x 700 x (500-900) mm. For larger volumes, the horizontal baler NKW180QT achieves 12-15 tons per hour.
3. How much does a hydraulic press for waste paper cost?
The price varies by model, configuration (vertical or horizontal, automatic or semi-automatic), and customizations such as voltage or logo. NKBALER offers customization options for technical parameters, voltage, block size, and color. For a detailed quote, it is recommended to contact the manufacturer directly with the specific project requirements.
4. Can I get a sample or test the machine before buying?
NKBALER offers the possibility to request a test video or a factory demonstration. Since the MOQ (minimum order quantity) is 1 unit, you can purchase one machine for pilot testing. They also provide remote after-sales support. To coordinate a visit to the plant in Wuxi, China, or request sample material, contact the sales team.
5. What is the lead time for a hydraulic baler?
