The ALLU Transformer TS drum assembly, manufactured for the existing ALLU Transformer D-Series material processor attachment frames, is an effective tool for pipeline padding and backfilling applications. Because it allows material to be screened onsite and then backfilled directly into a trench, it eliminates the need for dedicated stationary screening or purchase of fine soil.
ALLU D-Series attachments work with wheel loaders, excavators, skid steers or backhoes to screen, crush, pulverize, aerate, blend, mix, separate, feed and load materials all in one stage — increasing the profitability and efficiency of pipeline construction operations.
The core of the ALLU TS drum assembly technology is the configuration of the screening blades that spin between the screening combs. The end product size is defined by the space between the combs, and different fragment sizes can be achieved simply by repositioning the combs. Because the screening combs carry most of the material weight, the drums and bearings experience less impact and load. The design of the assembly ensures the machine works well in wet and dry materials without clogging, according to the manufacturer.
In a real-world case study, one pipeline contractor recently realized 80 percent savings per cubic yard using an ALLU D-Series attachment with TS drum assembly — the ALLU DH 3-12 TS16 — on a standard excavator. In looking at several options, this contractor realized the following:
Option 1: Traditional Screening
Option 2: Purchase Fine Soil
Option 3: Crush and Screen it with ALLU DH 3-12 TS16
Total Savings for Customer: $3.84 / cu. yd. — or 80 percent savings per cubic yard
The TS drums are available with two different blade types: standard blades for screening applications and axe blades when a crushing or shredding effect is required. Blade sizes available include 0.63/1.26 in. (16/32 mm), 0.98/1.97 in. (25/50 mm) and 1.38 in. (35 mm). The TS assembly is available in seven different models for 17.6- to 49.6-ton (16- to 45- t) excavators and 7.7- to 33-ton (7- to 30- t) wheel loaders.
