Q:Details of plant & machinery of Essential oil from Eucalyptus?
i've got no idea, but i'm really sorry
Q:Giant Farm Machinery from 1900's, History of it?
I think you are mistaken about the size. From what I've seen on cable and various museums, steam and later gasoline farm implements were very modest in size. But, you are welcome to keep looking.
Q:Looking for something that you put over machinery to silence them?
foam insulation board,make your own pretty cheap.
Q:how to procure ceramic machinery?
There are many ceramic suppliers across the country. SInce I don't know where you are located I can offer the following. The link below is to my web page that has a listing of ceramic suppliers I use. Some are in the northeast, like Bailey Pottery, Ceramic Supply, and Sheffield Pottery, where I live. If you are in that area, then they deliver on a regular basis. For many things I shop around, and both Axner and Bennett's in Florida have very good prices. But check for sales on different items. At these suppliers you can get kilns, wheels, pug mills, clay mixers, grinders, glazing machinery and more. If you are wanting to go to the supplier, then google ceramic suppliers in your home town. Many times you will want to actually try out the equipment, such as a wheel. The third option is used equipment that you can find on Ebay, Craig's List, your local penny saver or Bargain News (if you have that paper). I have found deals at estate sales and also by checking the bulletin boards at local art schools and craft centers. Good luck with your search.
Q:Does mechanic repair thing like agricultural machinery, tractor or not?
IF he is mechanic of agricultural machinery,yes of course he he/she can fix the tractor who have good idea of tractor machines.
Q:how can i break open a large hollow rock without machinery?
Sledgehammer!! Explosives!!
Q:I want to learn engineering machinery application technology, but I do not know whether the profession is good or not, how about employment?
The profession is very good, employment is particularly easy, and if you do not hate physics, it is not so hard to learn. This year, the school is not circulated a piece of it, a large enterprise to recruit machinery students, the boss said: "you just do not have a diploma, as long as there are student cards, we want you.". It shows that employment is fairly good, but the fact that wages are not particularly high is a fact. For example, when you enter a bank, you can take 5K months, and the machines may look like 2K to 3K.
Q:Cost of construction machinery use fee
The demolition charges and field freight: the demolition fee refers to construction machinery installation and artificial materials and mechanical disassembly required for commissioning costs and depreciation, machinery and auxiliary facilities erection, demolition and other expenses in the field; field freight refers to construction machinery whole or split from the parking place or transported to the construction site from a construction site to another site transportation, loading and unloading, auxiliary materials and wiring costs.
Q:how has the heavy machinery industry changed over the last couple of years?
I just got out of that line of work... grade construction, actually. The biggest thing I've noticed... you remember all the immigrants who came over here and started work as laborers or doing the dirty work? Well those guys pretty much run all the machines now. I'm not trying to sound racist, but the problem there is that they're willing to work for far less money than a lifelong U.S. citizen. That makes companies not want to hire as many of us. Why would they? They're saving money.
Q:What Gym Machinery should I use?
You should know you can get strong shaped and feel great with no machines!! Now I weight train so I do (I'm 206lbs 6'0) But alot of the times for my hamstrings, quads and buttocks, I just simply take two dumbells start off with about 20lbs and do 15 reps of squats and 5 sets of those! I usually kiss the ground with the dumbbells at around rep 10-15!! Oh my this will feels so goooooddddd!!!! Push ups I do those everyday 100 reps!! I get most of my chest mass from just push ups!! Arm curls and hammer curls is what will make your arms strong and/or tone!!
