Demolition specialist turns to trailer-mounted plant

The dynamics of doing more with less are drivers in recycling as cost per tonne is the measurement for economical processing. A company that has invested in productive mobile equipment is City Circle Demolition.

City Circle has grown as Melbourne has expanded, and old has made way for new. Demolition of industrial buildings, commercial premises, houses and waste streams in a city like Melbourne have aligned the company with a need to crush and produce saleable products from recyclable materials.

After 30 years in the contracting and processing industry, owners Peter and Deborah Skidmore decided to invest in new equipment with a strong pedigree in recycling and efficient low cost per tonne processing of all types of materials.

With three Extec C12 jaws, Kawasaki 1200 cone, HP300 and Finlay track screen, Peter and Deborah had the equipment to handle most jobs. However, it was not giving them the throughputs they needed. A review of the available crushing and screening equipment that performed at the most economical and highest productive outputs lead them to Lippmann, a Milwaukee-based manufacturer of high quality mobile and static crushing equipment for the mining, quarrying and recycling industries. Lippmann has a reputation globally for supplying one of the most durable jaw crushers in the industry and its equipment is backed by a standard three-year warranty on the entire jaw crusher range.

Peter examined and finally decided on a Lippmann 3062 trailer-mounted jaw plant. The jaw is fitted with a fully hydraulic toggle that enables quick adjustments while crushing as well as instantaneous tramp relief on steel and non-crushable items. This reduces downtime dramatically, translating into higher productivity. Lippmann jaw crushers have a range of sizes to suit various applications that goes all the way through to 5260.

Fed with a 62? x 18? vibrating grizzly feeder, this plant has capacity of close to 600 tonnes per hour in certain applications. Its operation and accessibility translates into minimum downtime and a high level of plant availability.

With three sites requiring the processing of concrete, asphalt and natural materials such as the basalt boulders found all over Melbourne, portability was key. The compromise of using tracked equipment was fresh in the Skidmores? mind as was the need to move it to clean spillage as well as poor accessibility. Good mobile trailer-mounted equipment is easier to keep clean, is simpler to maintain and is more productive, translating into lower cost per tonne of finished product.

The 3062 Lippmann jaw can process 300 tph of concrete with reinforced steel at 95mm settings, meaning a product free of steel ready to feed through to the secondary. The Extec C12s could not deliver such results.

With the increased capacity of the 3062, the stage was set for a closed circuit secondary plant that would combine versatility on raw feed and efficient screening for a clean final product. The need for mobility brought City Circle back to Lippmann and its 5165LS closed circuit plant.

This unit is fitted with a Lippmann 5165LS impactor and a TSH6203-32 flat screen. The impactor can be run with two or four bars and accept feed sizes of up to 600mm, thus allowing a wide variety of feed sizes and material to be processed.

The wide discharge and feed belts and the screening capacity of the TSH6203-32 flat screen enables the plant?s productivity to be very high with three finished products available. Typical production is 300 tph.

The combination of these two plants will open up other crushing opportunities as a low-cost producer of recycled and natural materials in an already competitive market.
