Manufacturers of Concrete Masonry and Summerhill Stone announce the installation at Hornby of NEW ZEALAND'S FIRST RAIL PNEUMATIC BULK HANDLING CEMENT PLANT Tremendous quantities of MILBURN Cement are used annually by VIBRAPAC in the manufacture of their high quality Concrete Masonry and Summerhill Stone. In the past all cement has been unloaded mechanically from open rail waggons and elevated by a bucket elevator into a 70 ton capacity silo . . a laborious, slow process.
