In process terms, the material in swept from the mill. The method of particle separation in static separator is a very basic process. The dust laden air swept from the ball mill flows upward into the bottom of the separator cone. As the air (gas) rises, it flows between the inner and outer cone until it reaches the inlet vanes.

Title: Air swept ball mill system. United States Patent 2398989. Abstract: This invention relates to air swept tube and ball mills for dry grinding to obtain a fine product. Ordinarily material discharged from the mill is a mixture of finished material of the requisite size and coarser insufficiently ground materials.

Roller mills can typi- cally handle raw materials with an aggregate moisture of 15% while ball mills are limited to about 8%. Ball mills used for drying should be air-swept using air velocity of 3-4M/sec above load. Normally drying is effected by ducting part of the kiln exhaust gas through the mill.

I know that the gas velocity in a normal Ball Mill should be around 1,5 m/s. Now the problem arrives when I want to use an Air Swept ball mill. So, anybody could tell me an average/normal value for the gas velocity in air swept ball mills? Thanks¿!!!!

23-10-2015· Vertical roller mills are developed to work as air-swept grinding mills. Roller mills are operated with throughput capacities of more than 300 t/h of cement raw mix (Loesche mill, Polysius® double roller mill, Pfeiffer® MPS mill). Loesche roller mill and Polysius® roller mills are widely applied in cement raw material grinding.

An object of this invention is to provide a simple, improved discharge and classifying chamber for air swept ball mills, having a diaphragm and frusto-conical screen for separating and discharging fine and coarse materials. It is a further object to improve the action of a frusto-conical screen in an air swept mill by fluting its external surface.

The Vortec Impact Mill offers controlled size reduction with a minimal production of undesirable fines at a fraction of the cost usually required to do the same task with a typical jet mill or ball mill. The air swept machine relies on particle kinetic energy for size reduction.

The products from both air swept and air impact pulverizers produce particles that do not require further sieving or classifying. Factors determining efficiency of fluid energy mills (i) The speed of air/inert gas. (ii) Feed rate and size. (iii) The configuration of the mill. (iv) Design of the classifier. (v) The position of the nozzle.
