Description

And fencing - refers to the technique of fine dry as well as wet grinding of various materials and can be used in the chemical, metallurgical, construction, pharmaceutical, perfumery and other industries.

Itveoma is a centrifugal mill containing two or three eccentric drive shafts with unbalances mounted parallel to each other on the bed, eccentric necks of the drive palms are connected to a U-shaped carrier frame, to which the tube chamber with the loading and unloading throats is rigidly connected. This type of mill has Paul because of the intense nature of the movement of the mummy bodies and the material itself in the auxiliary baoban, since the inertial sipy that are on the milling bodies and the maseryl itself. several times higher than in a vibratory milling mill, which contributes to the effect of flexive grinding and activation of the material, while reducing oud. H-n energy costs.

The disadvantage of such a mill is the difficulty of balancing the eccentric drive shafts, in addition to static balancing, it is also necessary to dynamically compensate for the additional forces arising from the movement of the loading of the p / mol chamber by grinding media and the material itself.

The aim of the invention is to increase productivity by improving the dynamic characteristics of the mill.

The goal is achieved in that the centrifugal mill is equipped with an additional grinding chamber with loading and unloading necks and carriers from both ends, and the drive shafts are made with additional eccentric necks, which are connected through the carrier to the additional grinding chamber, the drive shafts being located in one vertical plane, and cameras with two hundred. ron from them

The centrifugal mill contains a housing 1, grinding tube chambers 2, carrier 3, drive shafts 4, eccentric necks 5 of drive shafts, drive shaft 6. gear 7

The mill operates as follows.

The source material through the loading neck is simultaneously fed to

molar chambers 2. which are rigidly connected with opposite carriers 3, perform, under the action of synchronous rotational movements of the drive shafts 4 and the antidirectional necks 5 of the drive

shafts 4 circular anti-directional movements Recycled material coming into the grinding chambers with grinding elements forms a dense compact core which under the action of

of inertial forces is constantly in motion, each element of this core moves relative to each other ps of the inner surface of the grinding chambers The longitudinal movement of the load is provided by translational / shorter mm along the molar chambers along a circular path, and also by the support of the loaded material, which contributes to the removal of material from the mill through the unloading neck

The invention improves the grinding efficiency and activates various materials due to a sharp increase in energy stress caused by significant inertial loads,

which will significantly improve the dynamic characteristics of the mill. The use of an additional grinding chamber increases the productivity of the mill.
