$8,000 Concrete Mixer Is Added By Killins Co.

New Equipment Being Installed; Trucks To Have Special Bodies

Delivery of centrally-mixed concrete in non-agitating truck equipment will be possible in the near future when the Killins Gravel Co. installs its new $8,000 concrete mixer at the plant on W. Liberty St.

The new equipment, which weighs 14,500 pounds, arrived this week by flat car from the T. L. Smith Co., in Milwaukee.

The company already has purchased six special concrete dumpers which, when placed on trucks, will allow each truck to carry four cubic yards of concrete.

The mixer itself will be placed on a concrete slab which has its own concrete foundations and columns. The columns will rise 19 feet in the air above the footings.

The new outfit will incorporate many of the latest developments in the industry. The plant additions were designed by Ayres, Lewis, Norris & May.

Sand and pebbles will be placed in the bins by means of a belt conveyer. Aggregates, cement and water will be weighed, and then batched into the two-cubic-yard mixer.

A tilting mixer has been chosen as the most efficient type, according to the company, since it discharges each batch faster than other mixers and without discharge segregation.

Air-entrained cement will be used exclusively. This is a mechanical action that distributes millions of minute air cells throughout the mix. These tiny bubbles of air form and act as ball bearings among the fine aggregate, give more plasticity, and permit substantial cuts in the amount of water used.

Deliveries can be made as far as 30 miles from the plant without the concrete setting up or segregating.

Operation of the new mixer is expected by April 1. Later in the year boilers will be installed so the firm can supply hot-mix concrete.

Giant Concrete Mixer Arrives Here

The two men are inspecting the giant concrete mixer which the firm plans to erect at its plant on W. liberty Rd. The mixer has a capacity of two cubic yards and will cost nearly $8,000 when mounted. Built by the T. L. Smith Co. of Milwaukee, the mixer was brought here by flatcar.
