Cement production involves the creation of a hydraulic binder by adding gypsum or other additives to clinker. This mixture is produced by combining raw materials like limestone, clay, marl, and iron or that contain various oxides and then heating them to a specific temperature.
In the cement and mining industry, the first step is preparing raw materials, which are obtained from furnaces and then homogenized, broken down, premixed, and milled before being sent to stock silos.
The raw mix is then sent to rotary furnaces via elevators for the sintering process, resulting in the production of clinker. These semi-finished products are then stored in silos before being ground with various additives, depending on the type of cement being produced.
The finished cement is then packaged, loaded, and unloaded in various forms, such as bagged cement, bulk cement, or big bags, depending on the customer's requirements.
Mining companies, on the other hand, work with quarries and deal with heavy and valuable loads, including marble. As such, they require drive systems that can operate 24/7, from machines used in processing output products to transfer systems used in material handling. NRW Drive Technologies offers rigid-body gear units with wide reduction ratios and high moment values of up to 800.000 Nm to meet the needs of cement and mining companies.
PCS series gear units of NRW Drive Technologies serving up to 60 tones of capacity are optimum solution partners for crane industry thanks to their silent, compact bodies and easy maintenance features.
Industrial type gear units operate especially under heavy working conditions, have rigid case, bear high moments up to 480000 Nm and stand out with silent operation and easy maintenance features.
D/M series parallel shaft mounted gear units produced with hollow shaft or solid shaft are commonly preferred in conveyor drive systems.
