The silt at this sand and gravel plant is dealt with via a belt press. In order to access the main working parts of the press, an operator had to climb a vertical set of ladders many times per day. To improve safety, the company decided to replace these with a wide set of stairs with non-slip treads.
In addition, the plant’s belt press requires the addition of two flocculants – one in liquid form and the other in powder. The powder needs to be placed in a hopper at shoulder height. This had previously been done using 25kg bags, but after reviewing this practice with its supplier, the company changed to using 15kg bags at minimal cost difference. |
