Sand mullers break up sand after it has been used in molds to facilitate sandcasting. By effectively breaking up the sand, it can be reused. The worm on a motor or on the "driven" side of the device will engage with a worm gear. The worm rotates continuously, and the spiral cut gears "worm" their way "along" the axis of the gear. The worm gear (or spur gear) engages with the worm and rotates continuously as well. Also, the worm gear will translate the rotary motion of the worm by 90 degrees. It is fairly easy to see how the unit works if you look at some pictures or drawings. Hey, how about some animation or video? Got a couple of links.

What is the similarities of plastering sand and concreting sand?
Plastering sand is find sand screened to suit the plaster coarse i.e. base coat or finish coat. For finish coat very fine sand is used. Sand for concrete is not sived if pebles are not present. Both sand shall be sweet sand, if from sea it has to be washed before use.
What is best for cement mortar fine sand or coarse sand?
Fine sand is best for mortar.
Is sand mixed with mortar mix for laying concrete blocks?
Not just any sand. Mortar sand. Mortar sand is a larger grain sand that has been washed and screened to remove any rocks or pebbles.
How does shear strength of fine sand effect by void ratio?
Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand. These two features governs the critical state shear strength parameters of the sand. Density, however, dictates the peak shear strength of the sand. i.e. the denser the sand, the higher the peak shear strength. But the critical shear strength remain the same. The denser the sand, the lower the void ratio. Shear strength of fine sand is determined by the angularity of the sand particles, the grading of the sand.

How many tons of sand are in a yard of sand?
There is approximately 1. 35 tons in a cubic yard of fine sand.
What is the principle ingredent of glass?
sand and heat.
What two principle elements combine to make sand?
Silicon and oxygen
What are examples of the principle of totality?
lunar eclipsea glass filled with watera container filled with sand
What is the recirculate position on a pool filter valve for?
intex sand filter is not working on filter only working on recirculate position.....what should we do
Will an egg timer work in space?
Most egg timers would work in space (zero gravity) apart from the sand hourglass type. The rely on springs and gears to keep time not weights.
Why would the flow meter stop working on the swimming pool?
Possibly a grain of sand or debris in the flow tube.
Can you drive your awd vehicle on sand?
Yes. While a vehicle with AWD doesn't enjoy the added benefit of having high and low range gears as a normal 4x4 vehicle does, for most purposes, it will do fine - especially in less tricky off-road situations like sand. Try to stick to driving on hard sand where possible, and remember that maintaining a constant, slower speed is the best way to drive in sand. Stopping in softer sand can make starting back up again tougher. Likewise, driving too quickly in sand can make the going tough, and the handling a little less predictable.
How tray dryer works when drying pure wet sand?
it works on the principle of taking moisture with the hot air blown on it. so heating is to be done till the EMC is attained.
What is the principle is involved in determining the volume of sand in water?
You can very accurately determine the volume of sand using water. If you just take some sand and measure the volume, a lot of the volume you measure is actually the empty space between the sand crystals. If you want the true volume of the sand, you must use the water method.To do this, start with a known volume of water (use a graduated cylinder for instance). Record this volume. The weigh out a certain amount of sand, and add this sand to the water. When you do that, the volume of the water will increase. Record this new volume. Then simply subtract the initial volume from the final volume. This difference is the volume of the sand particles. You can also calculate the density of sand by this method since you weighed the sand before adding it, and the density is just weight ÷ volume.
On hayward pool filter Gauge reads 21 and the jets not working properly?
Sounds like your filter needs to be cleaned: DE < BUY THE FITER CLEANER> SAND: GET NEW SAND CARTRIDGE: BUY THE FILTER CLEANER
Does pool sand wear out and need to be changed?
Yes it does. I've replaced my sand twice in 12 years. But I know others who have not. Depends on the amount of debri it has to remove and what type. I have too many nearby trees. I knew my sand was finished when the back pressure got so high it blew out the skimmer basket when it turned off. Replacing the sand takes a couple of hours. Good luck. Sand needs to be replaced every three to five years. Proper backwashing and treatment with a sand revitalizer will keep your filter working efficiently throughout the sand's useful lifecycle.
How do you solve landslide?
You can model a landslide with nothing more than dry sand and a dinner plate. Pour a pile of sand on the plate and notice that the angle of the sides of the pile are stable. Tip the plate slightly and the sand will slump off to try to re-establish that stable angle.
