This Machinery is used to grind a variety of minerals for providing the needed powders with sorts of rough and fine grading for many industries.
Just like the earlier grinding wheels in the past, Pendular Mill is able to turn the ore to the powder as the result of a wheel movement on the machine body.
This machine components contain a series of Pendulums which turn around the pendulum axle and these Pendulums also are connected to an axis in central part of the mill, and these are in a rotary circular motion.
These wheels are in touch with the mill body that makes the ore turned to the powder by a series of located paddles at the lower part of machine. The ore is poured between wall and wheels and then, ore turns to powder in the result of abrasion between these parts .Next, powders are transferred to the Back Filter .One Filter then collects this powder and pours it on a spiral conveyor. After that, the spiral Conveyor leads this the powder out of Filter and sends it to the Storage tanks by Conveyor belts.
This Set has the ability to produce the whole material related to ceramic and fireproof factories containing panel and brick, tile, porcelain, and all industry of fireproof, cement and glass manufactures. As well, this machine productions are in the range of 45 to 250µ and, its maximum percentage of output is in 100 micron. Of merits of this machine is the simple reliable utilization, permanent and stable operation and, low energy consumption.
The experiment of particle size specification:
It is customary that Sieve analysis is used to gain the grain size of sand, gravel and, other kinds of soil grains. The method is illustrated in ASTM C 136. To do this, a group of Sieves that their bottom’s holes have an accurate specified size are used. This bottom’s netting of the Sieve is shaped with the cords and strings.in this way, Sieve collections are placed on each other so that the sieve with bigger holes are situated on the top and smaller sieves at the bottom.
After that, the dried soil with its all broken hunk (in the shape of just soil grains) is poured over the top sieve to shake for an unknown standard while. It is obvious that the tinier grains pass from sieve holes and bigger ones remain on sieve cords .This method is logical for larger soil seeds but it is not appropriate for smaller than a range , because the very fine particles of the soil stick to each other and accordingly, the sieve method does not work well. If the amount of soil tiny particles are high, you may have allow to pass the water on the soil and its rough grains and start to sieve after bigger particles being washed (vanishing hunks).
Test description:
Firstly, some soil should be dried, and heated in the weight of 200 gr. Next, the weight soil is poured on the first sieve of vibrating machine and set the alarm on 15minutes ,then press the start button. In this stage, the machine begins to vibrate and sieve the existing soil in the vibrating sieve. After time ends, the set turns off automatically. Then the remained amount is calculated:
remaining percentage on the sieve=(remained weight on one sieve/whole poured weight on the set)*100
It is noteworthy that sieves mesh no. selection can differ considering particle size and type of work
Mesh (Particle size):
In geology, Mesh referes to desired Soil grading for Sieving it meaning that the size of desired Soil particles for passing from Sieve is named Mesh, and it is a mass of Soil or compound powderof different grading , containing a distribution of varied sizes.
