SAFETY INNOVATIONS We present five projects and programs — from a pool of 35 U.S. and Canadian facilities — that improved safety at cement plants in 2012. Portland Cement Association's Occupational Health and Safety Committee looks for examples of how the cement industry is making its plants safer places to work. The goals of the Safety Innovation Awards are: 1) To honor innovative practices, programs, and projects throughout the industry. 2) To communicate these ideas to members of the North American cement industry. 3) To raise the profile and importance of safety programs both inside and outside the industry. MILLING AND GRINDING BUZZI UNICEM USA, LONESTAR QUARRY AND MILL RAW MILL LINER CART Employees at Buzzi Unicem's Lonestar Quarry and Mill in Cape Girardeau, Mo., developed a mechanism that eliminates the need to manually handle raw mill liners. Working with 1/4-in. wear plates, maintenance men and their supervisor built a compact cart to transport the liners inside the roller mill. The wheels on the cart are angled to follow the contours of the inner bowl in the mill. A small electric hoist is used to lower the cart into the bowl area where the hoist is positioned to receive the mill liners, and a washer is welded to the liner so it can be lowered by the hoist onto the cart. 34 CEMENT AMERICAS • Spring 2013 • www.cementamericas.com
