D&D Cranks Up Production With MCB 516REG Trommel

Mon September 15, 2003 - Northeast Edition

D&D Enterprises Inc. loves variety. The company focuses on landscaping and masonry restoration in the greater Boston market. At times, D&D goes from building ball fields to pouring seawalls while the tide is out.

Recent D&D projects include:

• Pemberton Park in Lawrence, MA — a $2 million redevelopment on the Merrimack River,

• Titus Sparrow Park for the city of Boston,

• Reconstruction of the sea walls at Hingham Harbor, and

• A historic masonry restoration at Methan Grey Court Park worth more than $900,000.

D&D is run by two brothers, RJ and Matthew, along with their father, Raymond. They currently employ 25 and have been growing steadily every year since the company’s inception in 1995.

D&D offers equipment rental with expert operators and has all sizes of dozers, loaders and excavators, as well as the new McCloskey Brothers 516REG trommel. The company also specializes in masonry restoration as well as the full range of concrete placement.

One of D&D’s largest endeavors is the construction and reconstruction of playing fields. These projects usually require removal of the entire top layer of soil so that the underlying ground can be raised, lowered or modified for proper contour and drainage. This overburden is a valuable asset that needs to be screened back to usable topsoil.

Under normal conditions, this can be a time-consuming proposition, but this year with all the rain, it was nearly impossible. Normal screeners just blinded over and, so as not to waste material, four or five screenings were necessary. This was costing a fortune in time and manpower, so D&D contacted Mike Lanchanski, of MCB Northeast, with hopes of finding a solution.

Lanchanski, who has more than 30 years of experience in the screener and trommel business, recommended the MCB516REG with a Cat 3054TA 120-hp, four-cylinder diesel engine. With a feed hopper measuring 4 ft. 6 in. by 12 ft. 9 in. and a 30-in. wide feeder belt, he knew D&D would be able to load using its large Cat excavator.

The rotary trommel screen can be changed in minutes. To vary the size of finished product, the rear door can be quickly opened and the 5 ft. by 16 ft. screen can be lifted, then slid out.

Removing the by-product is done on two levels. First, all material is dropped through a hydraulic grizzly. This large set of bars across the top of the infeed deflects the large stones so they never enter the screen area — subsequently, the stones are discharged harmlessly to the side of the unit for cleanup with a loader. If the grizzly were to get obstructed by roots or rocks, the operator hits a button on the remote and the unit hydraulically flips open to dump.

Once the material enters the hopper, it is fed into the trommel at a steady pace by the feed belt. As a result, the material flow is smooth and consistent. After the material travels the 16-ft. distance of the trommel screen, the waste product is disgorged onto a 30-in. wide discharge conveyor, which builds a spoil’s pile far from the rear of the machine thereby giving the operator long working intervals between cleanup passes.

Finished screened product discharges out a 24 in. by 30 in. remote controlled radial stacking conveyor, which has a 180-degree radial stacking capability (an MCB exclusive).

RJ, of D&D, said that he has been getting 500 yds. a day in the pouring rain. When it dries up he gets double that.

MCB Northeast sent Brendan Fox, an MCB factory-certified specialist, to go over every aspect of maintenance and operation. According to Fox, a properly trained operator virtually eliminates down time.

MCB Northeast has three trommel specialists and 13 sales representatives in New England and New York, as well as four mobile service trucks fully equipped with cranes, compressors and welders. MCB’s three regional parts centers have an extensive parts inventory.
