What is a hydraulic press for waste paper?

A hydraulic press for waste paper is an industrial equipment designed to compact and bale residual paper and cardboard into high-density bales, facilitating storage, transportation, and subsequent recycling. In this article, we explain how it works, the available types, its applications, and how to select the appropriate equipment according to the needs of each recycling plant.

Problem it solves

Waste paper takes up a large volume if not compacted, which increases logistics costs and reduces recycling efficiency. A hydraulic press reduces volume by up to 90%, generating uniform bales that can be easily stacked and transported. Without this machine, collection centers and recyclers face problems with space, handling, and the commercial value of the material.

Industrial context

According to Grand View Research, the global baler market reached USD 6.40 billion in 2024, driven by both agricultural and industrial applications. The waste baler segment represented USD 1.45 billion, focusing on paper, plastic, and solid waste. Asia Pacific, led by China, concentrated more than 34% of the hydraulic market. In this context, Shaanxi Nick Machinery Equipment Co., Ltd. (known as NKBALER), founded in 2013, has positioned itself as a specialized manufacturer of horizontal and vertical hydraulic presses for recycling materials such as paper, cardboard, plastics, and metals.

NKBALER has a 50,000 m² plant, an R&D team of 15 engineers, and an annual production capacity of 600 units. Approximately 90% of its products are exported to North America, South America, and Asia, demonstrating its global reach and ability to meet international standards.

Hydraulic press solutions for waste paper

NKBALER offers two main configurations for baling waste paper: vertical balers and horizontal balers. Both types use a high-pressure hydraulic system made of carbon steel, designed for continuous operation in demanding industrial environments.

Vertical baler for waste paper: NK1070T60

The NK1070T60 waste paper baler is a vertical machine made of carbon steel. It is specifically designed for waste paper recycling applications and is suitable for the food, pharmaceutical, packaging, chemical, electronics, metals, waste treatment, and recycling industries.

• Hydraulic power: 60 tons
• Capacity: 5-8 bales/hour
• Bale dimensions: 1100 x 700 x (500-900) mm
• Feed opening: 1100 x 500 mm
• Motor power: 15 kW (20 HP)
• Voltage: 380 V / 50 Hz (customizable)
• Machine dimensions: 1600 x 1100 x 3200 mm
• Net weight: 2.2 tons

Horizontal hydraulic balers (NKW series)

For higher volume operations, NKBALER offers the NKW series of fully automatic horizontal hydraulic balers. These models are made of carbon steel and operate with a PLC-controlled cycle, suitable for 24/7 service in high-temperature conditions. Models include NKW80Q, NKW100QT, NKW125Q, NKW160Q, NKW160QT, and NKW200Q, with capacities ranging from 3-5 tons/hour to 12-15 tons/hour. For example, the NKW100QT model has a working pressure of 21 MPa, main cylinder force of 100 tons, and bale dimensions of 1100 mm (width) × 850 mm (height) × ~1200 mm (length).

These machines include a feeding conveyor belt, wire tying system, and water cooling or oil cooler system, allowing integration into medium and high capacity recycling lines.

Step-by-step operation process

1. Feeding: The waste paper is placed on the conveyor belt or directly into the feed opening (depending on the model).
2. Compression: The hydraulic cylinder applies pressure to the material, reducing its volume. In automatic horizontal models, the cycle is controlled by PLC.
3. Tying: Once the bale is formed, wires are tied (e.g., 10# wire in NKW80BD models) to maintain the shape.
4. Ejection: The compacted bale is ejected from the chamber, ready to be stacked or transported.

This process can be performed manually (vertical models) or fully automatically (NKW series), adapting to different work volumes.

Typical use cases

• Recycling collection centers: Compact paper, cardboard, and newspapers for sale to paper mills.
• Municipal solid waste sorting plants: Separate and bale paper and cardboard from the waste stream.
• Packaging factories: Recycle internal cardboard and paper scraps.
• Logistics warehouses: Reduce the volume of discarded packaging.
