Difference Between Shell Trunnion Mounted Ball Mill

Besides, the diameter of the hollow shaft at both ends of the barrel of the sag mill is large and the length is short.The diameter is large for its large feeding size.Generally, the inner diameter of the hollow shaft is about 2 times of the larger ore feeding size, which is about 0.2-0.3 times of the inner diameter of the ball mill.The short length is for the higher speed of the flow of ore.

5.At what speed stirred mill operates?a) 50 to 500 rpmb) 5 to 10 rpmc) 10 to 500 rpmd) 100 to 1500 rpmview answeranswer: dexplanation: in a stirred mill, a central paddle wheel or impellor armature stirs the media at speed from 100 to 1500 rpm.Advertisement freestar.Queue.Push(function () { googletag.Display('sanfoundry_300x250_320x50_320x100_inlist2'); }); 6.What does colloid mill produces?a) emulsions and solid dispersionsb) wet and dry productsc) coarse and fine particlesd) broad particlesview answeranswer: aexplanation: colloidal suspensions, emulsions and solid dispersions are produced by means of colloid mills or dispersions mills.7.The clearance between rotor and stator is ______a) 5 to 10 mmb) 1 to 2.5 mmc) 0 to 1.25 mmd) 5 to 15 mmview answeranswer: cexplanation: the mill consists of a flat rotor and stator, the clearance between the rotor and stator is generally 1 to 1.25 mm.8.The power consumption of colloid mill is _______a) very lowb) optimumc) criticald) very highview answeranswer: dexplanation: the power consumption is very high and the material should therefore be ground as fine as possible before it is fed to mill.9.The speed of a rotary knife cutter is ___a) 100 to 500 rev/minb) 200 to 900 rev/minc) 400 to 600 rev/mind) 50 to 60 rev/minview answeranswer: cexplanation: a rotary knife cutter contains a horizontal rotor turning at 200 to 900 revolutions per minute, which is cylindrical chamber.10.______ indicates the impact of resistance.A) toughnessb) rigidityc) brittlenessd) fatigueview answeranswer: aexplanation: toughness indicates the impact of resistance.It is the inverse of friability and brittleness, it is also a deciding factor for commutation.Advertisement freestar.Queue.Push(function () { googletag.Display('sanfoundry_300x250_320x50_btf_1'); }); sanfoundry global education & learning series mechanical operations.To practice all areas of mechanical operations, here is complete set of 1000+ multiple choice questions and answers. prev page - mechanical operations questions and answers intermediate and fine crushers next page - mechanical operations questions and answers advantages of ball mill.

Dear allcan anybody suggest me how to calculate the material retention time in a closed circuit ball mill in each compartment?similarly for a vertical mill.What is the use to calculate the same?is it helpful for optimisation like in kiln ?please do reply raj.

In the case of the ball mill 1012 upgrade, the original planning included 90 days to execute the project.The proposal was analyzed thoroughly, and the revised plan called for the completion in 82 days of work.This involved, among other tasks: changing the rotor, stator and cooling boxes of the gmd system, as well as redesigning the discharge of the mill. these changes would achieve an increase in available power and also increase the level of filling required to treat harder ores, in turn realizing an increase of 4.4% in terms of processing capacity.All these tasks were completed within the tight schedule.

Good wear resistance and long service life: cement ball mill adopts the high-quality wear-resisting material, and the lining can be removed, therefore the service life of the equipment or vulnerable part is all longer.

Characteristics1.Vsi crushing machine is a new type rock crushing equipment developed in the 1990s and is used for substituting roller and ball mill.2.The structure is simple and the operation is stable;3.Low energy consumption, high output and big reduction ratio;4.Small bulk, convenient operation, installation and maintenance;5.The product is in the cubic shape with small iron pollution;6.During the process, the stone rock can form a protective bottom layer which makes the equipment more durable;7.Some easy wear parts adopt hard and wear-resistant materials and have small bulk and light weight, so that it can be changed easily.

Because of the different structure, the occupied area of grinding machine and ball mill is obviously different.

With the same end-products fineness and motor power, its output is over 1 time of that of jet mill, mix mill, and ball mill.
