Description

(5) ЦЕНТРОБЕЖНАЯ МЕЛЬНИЦА(5) CENTRIFUGAL MILL

Изобретение относитс к области строительного машиностроени и касаетс устройств дл измельчени материалов .The invention relates to the field of construction machinery and relates to devices for grinding materials.

Известна центробежна мельница, содержаща корпус с загрузочным и выгрузочным отверсти ми, внутри которого с возможностью вращени на вертикальных ос х установлены валки и привод, и снабженна смонтированной с возможностью вращени чашей в виде усеченного конуса с установленными с зазором валками в виде усеченных конусов, причем большие основани конусов чаши и валков обращены в сторону загрузочного отверсти 1 ,A centrifugal mill is known, comprising a casing with loading and unloading openings, inside which rolls and an actuator are rotatably mounted on vertical axes, and equipped with a truncated cone mounted with rotation, with rolls in the form of truncated cones, and large the base of the cones of the bowl and the rolls are facing towards the loading opening 1,

Недостаток известной мельницы состоит в невысоком качестве измельчени строительных материалов.A disadvantage of the known mill is the low quality of grinding building materials.

Цель изобретени - повышение качества измельчаемого продукта.The purpose of the invention is to improve the quality of the ground product.

Эта цель достигаетс тем, что центррбежна мельница, известна по авт.This goal is achieved by the fact that the mill mill, known by the author.

св. № , снабжена дополнительными валками, вертикальные оси которых св заны с основными посредством поворотных рычагов.St. No., provided with additional rollers, the vertical axes of which are connected to the main ones by means of pivoting levers.

На фиг. 1 изображена центробежна мельница, общий вид; на фиг.2 - то же, вид в плане.FIG. 1 shows a centrifugal mill, general view; figure 2 is the same, the view in the plan.

Центробежна мельница содержит корпус 1 с установленным в нем вертикальным валом 2, св занным с приводом (не показан) и несущим муфты 3 и , соединенные жестко с балками 5 и 6, в которых закреплены вертикальные оси основных вапков 7 и 8. На оси валка 8 установлены поворотные ры15 чаги Э и 10 с осью дополнительного валка 11, а на оси валка 7 установлены пбворотные рычаги 12 и 13 с осью дополнительного валка 1t. Корпус 1 снабжен выгрузочным отверстием 15, The centrifugal mill comprises a housing 1 with a vertical shaft 2 mounted therein, connected to a drive (not shown) and bearing clutch 3 and rigidly connected to beams 5 and 6, in which the vertical axes of the main hinges 7 and 8 are fixed. On the roll axis 8 rotary arms 15 chaga E and 10 are installed with the axis of the additional roll 11, and p-turn levers 12 and 13 with the axis of the additional roller 1t are installed on the axis of the roll 7. The housing 1 is provided with a discharge opening 15,

20 загрузочным отверстием 16 и имеет конусообразную форму.20 with a filling opening 16 and is tapered.

Claims

Centrifugal mill works as follows. 390 The material to be ground is loaded through the opening 16 into the housing 1 and then the drive is turned on. When the shaft 2 rotates, the main rolls 7 and 8, rotating with the beams 5 and 6 forming the rotor, produce a grinding process around the axis of the shaft 2 and their axes between the walls of the housing 1 and the surface of the rolls 7 and 8. the additional rolls 11 and, mounted on the pivot arms, under the action of centrifugal forces, are pressed against the wall of the housing 1, simultaneously rotating around their axes. As a result, the material between the wall of the housing and the surface of the rollers is ground and more qualitatively than more soon shaft rotation

2. The ground material rolls down the inclined wall of the housing to the discharge opening. High quality of the material grinding is provided by a combination of the cone-shaped rollers, the body and the installation on the axes of the Main rolls of the swivel levers with the axes of the additional rolls, which are caused by centrifugal forces. Invention Formula Centrifugal Mill auth. St. No., in order to improve the quality of the crushed product, it is equipped with additional rollers, the vertical axes of which are connected to the main ones by means of pivoting levers.
