Cement clinker grinding unit, or called cement grinding plant, cement grinding station, is an individual grinding plant in the finished cement production. Cement grinding plants are primarily used to produce finished cement products by grinding cement clinkers and moderate mixed materials.
After gypsum, clinker, and limestone are measured by the belt weigher, they will be mixed together in accordance with particular proportions, and then sent to the stable weighing warehouse. During this process, magnetic metals are removed by the iron remover from these materials. Then mixed materials will be sent into the vertical cement mill for grinding. After grounding, the coarse powder will be sent back to the grinding mill while the qualified material will be sent to the elevator for finished products. Finally, they will be sent to finished product storage.
The core equipment of the grinding plant is the cement mill. Depending on the grinding system, the commonly used cement mills are cement ball mills, roller presses and vertical cement mills. CHAENG can provide a variety of schemes for cement grinding, and make a choice according to the actual situation and needs of customers:
Closed-circuit ball mill system
Combined grinding system
Vertical roller mill finish-grinding system
