      THIS IS A SITE FOR ARTISTS, NOT CLIENTS (Please read before posting)   04/18/2018

      I'm seeing a lot more questions from people who are looking to get tattoos, asking about ideas, healing instructions, etc. These are questions you should ask YOUR  LOCAL TATTOO ARTIST, not random people on the internet. This site is specifically for tattoo artists and those looking to get into the trade by way of an apprenticeship. Don't be shy! Google local artists and drop by a shop or two, check out their portfolio of work and talk about your ideas with a professional who can help you achieve the best tattoo experience. 

       Thanks for reading!

Ensure the right mixing equipment mounted to agitation tank

Recommended Posts

The Agitation Equipment of yields stress fluids with a six-curved-blade impeller is numerically investigated. The xanthan gum solution in water which is used as a working fluid is modeled by the Herschel–Bulkley model. Investigate the effect of vessel design on the flow patterns, cavern size and energy consumption. Three different vessel shapes have been performed: a flat bottomed cylindrical vessel, a dished bottomed cylindrical vessel and a closed spherical vessel. The comparison between the results obtained for the three vessel configurations has shown that the spherical shapes provide uniform flows in the whole vessel volume and require less energy consumption. Effects of the agitation rate and the impeller clearance from the tank bottom for the spherical vessel are also investigated. Some predicted results are compared with other literature data and a satisfactory agreement is found.

Dry dilute acid pretreatment at extremely high solids loading of lignocellulose materials demonstrated promising advantages of no waste water generation, less sugar loss, and low steam consumption while maintaining high hydrolysis yield. However, the routine pretreatment reactor without mixing apparatus was found not suitable for dry pretreatment operation because of poor mixing and mass transfer. In this study, helically agitated mixing was introduced into the dry dilute acid pretreatment of corn stover and its effect on pretreatment efficiency, inhibitor generation, sugar production, and bioconversion efficiency through simultaneous saccharification and ethanol fermentation (SSF) were evaluated.

If your agitation tank and accompanying mixing equipment is not operating at peak efficiency, or is simply not doing the job, then you should certainly look into replacing your equipment. Here, you will need to find the right company for the job. Not all companies out there that offer this equipment for sale service that equipment down the line. In fact, it’s often better to use a company that designs their own agitator tank options, as well as their own impellers, impeller shafts and other required equipment. This ensures that you are able to work with the best possible provider, and that you will be able to rely on their service, expertise and experience down the road.

You will also need to ensure that you have the right mixing equipment mounted to your agitation tank. The right size and shape impeller is vital to keeping your mix in suspension. However, the impeller shaft is also an important consideration. Too thin of a shaft can lead to premature wear and breakage, while too thick of a shaft can also cause issues. The agitation drive is also important, as is the motor – you need sufficient torque and power to keep your mixture in suspension, without worrying that prolonged use will lead to premature wear on the motor or the drive.

Thickening Equipment developed lately in China. The first thickener was made in accordance with Soviet-style thickener. With about a decade of exploration, a series of thickening products are produced in the mid-1960s., which met the needs of the middle and small scale dressing plants in domestic basically. By the 1970s, thickening equipment was in the trend of systematization and standardization, and the classification became more complicated. As the policy of reform and opening up in the 1980s, lots of new technology and advanced equipment were introduced into China, which promoted the rapid development of the thickening in China.
