Can banna peel really whiten teeth?5 answersBanana peels can indeed contribute to teeth whitening. The active components extracted from banana peels have sterilization, anti-inflammation effects, and hairdressing properties due to the presence of potassium, vitamin A, and vitamin C. However, it is essential to note that while natural ingredients like banana peels can have whitening effects, other traditional practices like brushing teeth with betel nut peel may lead to negative effects such as tooth discoloration and abrasion. On the other hand, herbal extracts like green tea, bay leaf, and lime peel have been found effective in removing extrinsic stains from teeth and dentures due to their abrasive materials and active agents. Additionally, the application of mangosteen peel extract has shown to reverse the reduced shear bond strength of orthodontic brackets after bleaching, indicating its potential in maintaining dental health post-bleaching.
What are banana peels?5 answersBanana peels are a valuable resource rich in bioactive compounds like carotenoids, polyphenols, and antioxidants, making them beneficial for various applications. They contain minerals such as iron, calcium, and dietary fiber, with potential health benefits like reducing cancer risk and aiding in toxin removal from the body. Additionally, banana peels can be utilized in different industries like cosmetics, medicine, food processing, and agriculture, offering a wide array of uses from fertilizer to anti-inflammatory remedies. Research highlights their antioxidant and antimicrobial properties, making them attractive for pharmaceutical purposes and as natural antioxidants. Moreover, banana peels can expedite the ripening process of bananas, offering a cost-effective and eco-friendly method for fruit traders. Overall, banana peels are versatile, offering benefits ranging from health applications to industrial uses.
What is the crushing circuit of el teniente?3 answersThe crushing circuit of El Teniente mine includes a material handling system consisting of a crushing chamber with a capacity of 60,000 tons per day and a 9 km long tunnel to shelter the conveyor belt. This tunnel is currently under construction and has experienced rockbursts. The control circuit of the food crushing device includes a power supply interface, a circuit board, a circuit protection device, and a motor. The circuit protection device switches off the control circuit when the current exceeds a preset value, preventing damage to the motor and circuit board. El Teniente mine processes partially weathered copper ores, and the recovery of molybdenum has dropped due to a greater moly oxide content and excessively fine moly particles. Steps have been taken to raise moly recovery back to the desired range, including a reduction in collector dosage and changes in the flotation sequence. The closed-circuit crushing system for milling wet cement raw material consists of a roll mill or roller mill and a separator device, specifically a static cascade separator, to achieve high milling efficiency with low energy demand.
What is the ore crushing process of ores of el teniente?3 answersThe ore crushing process of ores of El Teniente involves several steps to achieve efficient grinding and reduce energy consumption. Firstly, the raw ore is coarsely crushed using a crusher. Then, the coarsely ground ore is separated into big crushed ores and small crushed ores through a vibration sorting machine. The big crushed ores are returned to the crusher, while the small crushed ores are fed into a grinder. Dust level ore is collected using an air machine connected to the grinder, and large-particle ground mineral is screened using a screener connected to the grinder. The coarse powder ore is returned to the grinder for further grinding, and the fine powder ore is collected. This multi-stage grinding process ensures good crushing effect and allows for obtaining mineral raw materials with different specifications. The ore crushing technique used in El Teniente mine involves coarse crushing, two-stage sieving, intermediate crushing, and fine crushing, with a simple structure, low cost, and high efficiency.
Can avocado peels be wet ground and macerated to produce a insecticide?3 answersAvocado peels can be wet ground and macerated to produce an insecticide. The method of wet grinding plus maceration (WGM) has been found to be effective in extracting bioactive compounds from avocado peels, including phenols, epicatechin, and chlorogenic acid. The WGM method has shown to yield the highest content of total phenols (2143.1 mg GAE/100 g dry weight) and the highest amounts of epicatechin and chlorogenic acid (181.7 and 244.3 mg/100 g dry matter, respectively). Additionally, the WGM extract has been characterized using UPLC-ESI-MS/MS and GC-MS. The utilization of avocado peels in insecticide compositions has been described, with the hexane, dichloromethane, ethyl acetate, and hydro-alcoholic fractions of avocado pits being incorporated into these compositions. Therefore, wet grinding and maceration of avocado peels can be a viable method for producing an insecticide.
How to processed sugarcane bagasse ash?5 answersSugarcane bagasse ash (SCBA) can be processed using various methods. One process involves drying, sieving, and washing the ash to obtain organic carbon black (OCB). Another process includes steam explosion of the bagasse, followed by enzymatic hydrolysis and settling separation to obtain clear liquid. Additionally, SCBA can be ensiled, dried, mechanically separated, and ground with other lignocellulosic materials to produce livestock feed and fuel biomass. These processes aim to utilize SCBA, which is an industrial by-product, and transform it into valuable products such as OCB, clear liquid, and cattle feed.
