Sierra--Macpresse Scrap Paper Balers

Sierra is the exclusive distributor for Macpresse in the United States. Recyclers using MAC balers have the lowest operating costs per ton with the highest hourly production rates. Our customers can process more than 30 tons per hour of OCC and more than 60 tons per hour of ONP. High grades are processed even faster.

All Macpresse balers use a combination of bolted and welded construction and feature wire-tying units known for the highest reliability in the industry. Wear liners in the charge box and extrusion chamber are made of Hardox 500 steel.

For companies trying to control costs in today’s competitive market, Macpresse balers offer many advantages, from reduced energy consumption to denser bales to safety features of the highest degree.

As with all of its equipment, Sierra backs each of its Macpresse installations with efficient, effective service.

112

The MAC 112 series baler has been specifically designed for the processing needs of high-volume recycling plants. A special hydraulic lock balances the baler’s 200 tons of compaction force with the counter-pressure force that restricts the material in the extrusion channel, maximizing density on every bale. This simple patented system greatly reduces operating costs and reduces the risk of mechanical failures. Maximum density is achieved on every bale to increase rail loading, reducing transportation costs.

111AS.1

The MAC 111AS.1 is the highest production baler available. Loose OCC is processed at rate of 25 to 39 tons per hour, while re-baled OCC is processed at more than 39 tons per hour. ONP, mixed paper and high-grades are processed even faster. Bales are sized to maximize shipping.

111A.1

The MAC 111A.1 is a completely automatic, high-production baler. It has two motors and pumps to provide maximum production and system redundancy. It includes a compaction trolley equipped with four large wheels, four upper wheels and four lateral rollers made of highly wear-resistant hardened steel. The shear blade is designed with a special serrated edge on the ram and a "V" shaped fixed knife, which Macpresse has patented. This two-stage shear eliminates the need for a pre-press flap apparatus. Hydraulic variable-flow pumps drive the ram with a power regulator that reduces energy and maintenance costs.

110.1

The MAC 110.1 is a completely automatic, high-production baler featuring a 100-hp motor and a variable flow piston pump to provide maximum production. It features the same compaction trolley and shear blade of our 111A.1 baler.

108.1

The MAC 108.1 is best suited to baling medium to large volumes of recyclable materials, including scrap paper, OCC and plastics. It is a completely automatic baler with hundreds of users worldwide. The Macpresse hydraulic system automatically adjusts the speed, the compaction force and the cutting speed of the trolley or ram. It includes the same shear and compaction trolley as our other machines. The shear blade, with a special serrated edge on the ram and a "V" shaped fixed knife, eliminates the need for a pre-press flap apparatus.

105

The MAC 105 is a completely automatic baler best suited to meet the needs of medium-sized recycling plants. It includes the same design features as our other balers.

All Macpresse solid waste balers have been specifically designed to meet the processing needs of municipal solid waste (MSW) and high-volume recycling plants. A special hydraulic lock balances the machine’s compaction force with the counter-pressure force restricting the material in the extrusion channel, maximizing density on every bale. This simple patented system greatly reduces operating costs and reduces the risk of mechanical failures. All models in the "L" series have replaceable liners in the compaction and extrusion chambers made of Hardox 500 steel.
