l For electrical machines under heavy vibration (e.g. traction motors): 350 - 500 g/cm2 (5.00 - 7.11 psi) Equal spring pressure must be maintained for all carbon brushes to ensure a good ... Current does not flow uniformly across the whole brush contact surface. It flows through a varying number of very small areas called contact spots. Ideally ...
A two level control strategy was used in industrial copper solvent extraction process. The stabilizing layer regulates the flow rates in the copper solvent extraction process [19]. The ...
Step 3: Smelting: mixing with coke/charcoal and heated at high temperatures (i.e 800 o C) for copper to keep Cu from remaining in sulfide form). Impurities are further removed by adding flux if not already present in ore (if gangue is acidic basic flux is added, if gangue is basic acidic flux (i.e., SiO 2) is used.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores …
The traction motor of EVs is responsible for converting electrical energy to mechanical energy in such a way that the vehicle is propelled to overcome aerodynamic drag, rolling resistance drag, and kinetic resistance. ... The converter acts as a power conditioner that regulates the power flow between the energy source and the electric motor for ...
The recycling of metals such as gold and copper from discarded end-of-life electronic waste (e-waste or WEEE) is an important aspect to the development of environmentally benign manufacturing processes that exhibit circularity in materials flow. Global e-waste production is increasing at a 3–5% rate, so it is concerning that only 30% …
ABSs are anti-lock braking systems that prevent vehicles from skiing or sliding. These systems are commonly found on aircraft and in vehicles on land, such as buses, cars, motorcycles, and trucks. ABS prevents the wheels from locking up when you brake, thus maintaining traction on the road.

A basic flow sheet diagram of preprocessing is shown in Figure 1. The expired equipments are manually dismantled at collection facilities and individual components are tested and isolated from e-waste. ... In these pyrometallurgical processes, e-waste/copper/lead scrap is fed into a furnace, whereby metals are collected in a …
copper – an intermediate product from the recycling of electronics. The result is known as blister copper, which has a copper content of 97-98 per cent. The blister copper is then processed in an anode furnace to reduce its oxygen content. This increases the purity level to 98-99 per cent and the copper is then cast to form anodes.
As one of the three basic relationships of high-speed railway (i.e., pantograph–catenary relationship, wheel–rail relationship and fluid–solid relationship), pantograph–catenary system is the key to maintain the constant and reliable power supply for high-speed trains, as shown in Fig. 1a and b, which contains two main components—the catenary and the …
