Saudi Arabia: China National Building Material (CNBM) subsidiary Sinoma CDI has won a US$6m contract to upgrade cement and raw materials conveyors at Riyadh Cement Company’s Riyadh cement plant. The producer has opted for elevator conveyors for mechanical transportation, in place of its existing pneumatic conveyors. It expects this to increase energy efficiency and reduce necessary maintenance. The project is due for delivery in early 2025.

Riyadh Cement Company CEO Shoeil Al-Ayed said that the project aligns with the producer’s strategic energy reduction initiatives.

US: Bulk material handling equipment supplier MDG America says that it delivered four chain bucket elevators for Drake Cement's upgrade of its Paulden cement plant in Arizona. Drake Cement installed a new vertical mill grinding plant for cement, granulated blast furnace slag (GBFS) and raw materials grinding at the 0.7Mt/yr integrated plant. The supplier says that two of the elevators will work in a pair, conveying material from a feeder belt, while a third will convey it to the new mill. The fourth elevator will then collect the material for further grinding and metal discharge.

Drake cement secured approval to mine pozzolan for use in the Paulden's plants cement production at Bill Williams Mountain earlier in October 2022. As part of minimising the future mine's impacts, Drake Cement has offered to help the US Forestry Service to thin local woodland as part of local anti-fire management efforts.

India: Aumund Engineering India has been selected by ACC to refurbish a 175.3m high bucket elevator, the tallest in the world. The elevator is installed at ACC’s Wadi Cement plant in Karnataka where it is used for raw meal pre-heater transport at a rate of 600t/hr.

Originally, the machine was fitted with a steel cord belt of width 1320mm and tension rating of 3150N/mm. Aumund has decided to offer an alternative based on its own design concept resulting in a belt width of 1300mm but with higher tension rating of 4000N/mm with a bucket size of 1250mm at bucket spacing of 450mm. The Aumund belt concept will use continuous close pitch longitudinal ropes without rope free bucket mounting spaces. However, it will use additional wire ropes running laterally across the width of the belt adding lateral stiffness without significantly changing the belt longitudinal flexibility. This cross-stabilised construction is intended to improve stability to the belt with improved bucket fixing.

To make the necessary belt punching, Aumund has developed a special punching machine design which gives clean fixing holes that are accurately aligned relative to the belt edge and at precisely the correct pitch. The belt is held in a cassette and advanced automatically under the punching frame using a precision encoder to measure the pitch. The belts are prepared at the Aumund production in Rheinberg, Germany and shipped to site at the exact required dimensions including a prepared joint and the required clamping connection.

In addition to the new belt the elevator will also be fitted with new drive pulley including friction linings and rubber bucket mounting strips. The casings, inlet and outlet plus the complete drive unit remain unchanged.
No commissioning date for the project has been announced.
