Crush Precise Product Sized for Maximum Yield

Gundlach Crushers are the preferred crushing solution for coal, potash, salts, lime and other higher value industrial minerals where precise product sizing, fewer fines and maximized yield are important. Gundlach makes roll crushers and breakers for primary and secondary crushing of product down to 10 mm. Exclusive 3-D roll crusher technology produces a cubical product in a single pass. Cage-Paktor® cage mills are used for particle sizing below 10 mm. Nanosiz-R® roll mill is designed for 19 mm feeds to 1600 micron product. Accu-Grind small tonnage crusher handles feeds up to 100 mm and is optimized for sampling applications and installations requiring a small footprint.

Roll Crushers Size in 3 Dimensions

Two-Stage, four roll crusher
with housing installed

Gundlach's single-stage, two roll crusher transformed how coal mines size product to meet market demands. It was the first crusher that in a single pass could economically break 50 mm coal to 19 mm pieces. The single-stage, two roll crusher was followed by the first two-stage, four roll crusher that could take run-of-mine coal and crush it to 19 mm size. To this day the Gundlach roll crusher design remains the only device to provide control over product size in all three dimensions. This 3-D crushing capability delivers higher quality product, less fines and consistently repeatable performance for coal, potash, salts, lime and other higher value minerals.

High Tonnage Breakers Yield High Value Product

These High Tonnage Breakers produce
high value product at PRB Coal Mines

The two-stage, four roll Gundlach breaker provides the high tonnage production required by today's largest mines coal mines. Gundlach breakers produce a higher quality product with less fines and the uniform sizing that power plants demand. The two-stage, four roll design eliminates the need for secondary crushing and extra handling, while reducing coal to precise, market ready product requirements. Like all Gundlach crushers, the two-stage, four roll breakers offer breakthrough crushing technology and Gundlach's commitment to building equipment with a long productive life and easy maintenance.

Cage-Paktor^® Cage Mill Minimizes Product Oversize, Increases Crushing Efficiency, Yields More Product in Specified Size Range

Easy maintenance, energy
efficient Cage-Paktor Cage Mill

The Cage-Paktor cage mill reduces 100 mm feeds to 2 mm product. This economical impactor design needs no screens and crushes only the over-size material, saving on horsepower and energy use. Gundlach improved on the standard cage mill design by moving both drives to one side of the machine with a revolutionary shaft-within-a-shaft design. This feature leaves one side of the mill fully exposed for easy maintenance of the cages and the housing liners, the only wearing areas of the machine. Hours of drive removal, realignment, and set up time are thus eliminated.

Nanosiz-R^® Roll Mill for Fine Grinding Applications

Nanosiz-R Roll Mill is a fine grinding
crusher for 19 mm feeds to 1600-micron
product and high capacity 40 tons per hour

Gundlach's Nanosiz-R Roll Mill is ideal for fine-grinding applications such as preparing limestone for mixing with coal to reduce the sulfur content of emissions. It's used in processing nitrogen, phosphate and potash and provides better control of the finished product size range. It produces less dust and generates little noise compared to other crushers in its class. Bi-Modal Crushing (Shear & Compression) provides the best solution for crushing friable materials. Multiple units can be used in series to achieve greater reduction ratios. High 40 tons per hour capacity.

Sampler Crushers for Low Tonnage Applications, Limited Space

Accu-Grind Sampling Crusher
offers high ratio of reduction

Gundlach 1000 Series roll crushers and Accu-Grind roll crushers are used for on-line production sampling and in low tonnage size reduction applications. They can be employed in on-line continuous sampling and low to medium capacity crushing applications such as hot ash crushing.

• The 1000 Series roll crusher sizes down to 6 mm, a typical 4:1 ratio of reduction and throughput up to 20 MTPH.
• The Accu-Grind has a reduction ratio of 16:1, capacity of up to 30 MTPH and product down to 6 mm.
