Next, the crushed bentonite is dried in rotary or fluid bed dryers fired with natural gas, oil, or coal to reduce the moisture content to 7 to 8 percent. The temperatures in bentonite dryers generally range from 900°C at the inlet to 100 to 200°C at the outlet. The material then is passed through a grizzly and crusher to reduce the clay pieces to less than 2.5 cm in size.Mined bentonite first is transported to the processing plant.
For the special application, we can choose other crushing or grinding machines configuration.This is the common feldspar production equipment and process.
As for crushing equipment, we need to have crushers, such as jaw crusher, impact crusher, cone crusher and so forth.The mica stone production equipment for Jharkhand,India largely like mica stone jaw crushing equipment, mica stone grinding equipment and some optional equipment. Like a main organization in mining market, we will provide ideal mica stone production equipment for India and also other nations. With regards to grinding mill, you have ball mill, Raymond mill, higher stress grinding mill and super thin grinding mill to choose.
For the stable grinding operation in the frictional grinding zone, it is important that the grinding operation executed by the table and the rollers is always maintained under the same grinding condition and a consolidated material layer is stably produced due to the pressure of the grinding rollers.In the frictional grinding zone, frictional grinding is carried out since a difference between the circumferential velocity of the table and that of the outer periphery of the roller is large. For this, there must exist sufficient material to be ground in the frictional grinding zone. Additionally, in order to produce the high quality products with the improvements in grinding efficiency and production ratio of the fine power, it is important that, as effective grinding pressure, the pressure of the rollers acts on the material to be ground in the frictional grinding zone effectively.
Further, said components may be protectively lined or covered with abrasion-resistant ceramic tiles of numerous descriptions. 3. This Outlet Turret Extension acts as a volume-increasing device which may be located either at the top of or the bottom of any existing coal pulverizer mill housing (or body). 1, the High Performance Classification System, all components of the said classification system are constructed of a steel material, either mild steel or of a wear-resistant type. Typical installation methods include a bolted and flanged arrangement or simply a weld-in modular design. Note that the Outlet Turret Extension is also shown in FIG. The Outlet Turret Extension will be constructed with a cross-sectional shape which is identical to the existing pulverizer mill body.In reference to FIG. 1, the Outlet Turret Extension 1 is located at the top of the existing pulverizer mill body 10. The specific design of the coal pulverizer mill will dictate the location and installation method of the Outlet Turret Extension. In FIG. This shape may be cylindrical, hexagonal, or any other shape utilized by coal pulverizer manufacturers. Also said components may be protectively lined or covered with welded overlays of high-alloy wear-resistant material.
The ore production at the actual mining site was calculated based on the number of times that the trucks hauled ore and the truck loading capacity. The crusher utilization was calculated by Equation (10), where UR is the crusher utilization (%), NH is the number of times that ore is hauled, AWT is the average working time of trucks at crushing area (min), and DWT is the daily work time (min).59 min for all work days.UR= NH × AWT × 100DWT (%). AWT was set to 0.After comparing the prediction accuracy of the trained DNN models, that with the highest coefficient of determination and lowest MAPE for the test data was selected as the optimal model. Moreover, the values predicted by the DNN model were compared to those observed at the actual mining site. To verify the optimal DNN model, the model was used to predict the ore production and crusher utilization occurring during truck haulage work over the course of 10 days, starting on 1 November 2018.
