Morbark 1600 puts out 700 cubic yards per hour
Touted as the most "purpose-built" machine in Morbark's 50-year history, model 1600 tub grinder purports to put up some impressive production numbers: up to 700 cubic yards per hour in green waste and more than 500 yph in stumps and logs, says Dan Brandon, marketing manager. These numbers can vary depending on material and screen openings, as well as operator and support equipment.
Base diameter measures 11 feet 2 inches, and tub capacity is 20 cubic yards, which Morbark says is the largest made. A choice of Caterpillar or Cummins diesel can provide a minimum of 1,000 or maximum of 1,200 horsepower. The six-foot hammermill offers 22 hammers as standard, allowing enough space between hammers to grind landfill material; mixed debris; and large, chunky wood. In regrind applications, users can convert to a 30-hammer pattern in an hour.
The company says the grinder can easily keep up with a 13-yard bucket feeding it material, and it built the discharge system with a 60-inch-wide belt for quick discharge. Morbark's three-auger system reduces abuse and wear on the belt, Brandon says, which can be damaged by "wood 'spears' that can be shot out of the hammermill at incredible velocity."
"These belts are a high-wear, high-cost replacement item," Brandon says. "Hard-surfaced steel augers are an efficient way to exit large volumes of material from under the mill." A pressure sensor will stop the tub if augers become overloaded.
Also standard on the 1600 is the company's Iqan system, although this is the first tub grinder that features the programming tool. A computer module receives input from hundreds of sensors that monitor hydraulic pressures, temperatures, loads, auger pressure, and other functions, Brandon says. The operator can set parameters based on the material in order "to achieve the greatest output while maintaining the optimum engine load."
"For example," he says, "if the discharge augers come under heavy load because of a large surge of material, the Iqan senses this and tells the tub rotation to slow down or even stop and reverse until the load on the augers reaches optimum parameters." In addition, Iqan has an optional satellite link that allows a service tech to monitor and diagnose problems.

Morbark combines heavy-duty construction and new technology in the 1300B tracked tub grinder
The all-new TG5000 tub grinder features a 60-inch-deep and 12-foot-wide tub opening. Vermeer says the bottom of the tub flares outward from the tub wall, allowing the hammermill to cut under the vertical wall of the tub, helping to reduce bridging and permitting steady feeding of material.
