Abstract

The utility model provides a ball mill driven by linear motion actuator, one end of which connects with a secondary stage of a metal disc, and which correspondingly is provided with a primary stage, which composes of a silicon steel sheet copper wire windings. The primary stage is a circle arc, which is corresponding to the metal disc secondary stage. The circle arc is linked by one section circle arc or more than two sections circle arc, which is convenient to manufacture and install, and the primary stage is arranged on the upper of the secondary stage by means of a fixing bracket. The utility model has the advantages of simple structure, reliable running, high system efficiency, useful for industry of building materials, chemicals, machines, etc.

Description

Ball mill driven by linear motion actuator

The utility model belongs to a kind of ball mill that industrial comminuting matter is used.

Existing ball mill is made up of mill body, steel ball, frame, motor, decelerator, drive.Because it has adopted decelerator that structure is increased, inconvenient maintenance, the system effectiveness of whole ball mill reduces.Simultaneously since ball mill the prestart steel ball all place the mill body below, when therefore starting, it is very big apart from needing that its starting is changeed, thereby in the practice, the motor of selecting for use by design often burns out.In order to address this problem, the motor of general ball mill has to select for use powerful motor, causes the phenomenon of low load with strong power, has greatly wasted electric energy.

The purpose of this utility model is to provide a kind of simple in structure, the ball mill of system effectiveness height, saving electric energy.

The purpose of this utility model is achieved in that its cardinal principle is that ball mill mill body is equipped with the LIM actuator, secondary (rotor) that the metal garden dish that this device is connected by mill body one end constitutes linear electric motors with constituted with this secondary corresponding elementary (stator) of linear electric motors of forming by silicon steel sheet, coil that is equipped with.

Above-mentioned linear electric motors elementary (stator) are with the metal garden and coil secondary corresponding garden arc, and this garden arc is joined by the garden arc more than a section or two sections or two sections and forms.So that make and install, processing technology is simplified.

Elementary (stator) of described linear electric motors is installed in the secondary top of dish, metal garden by a fixed mount.Because the primary and secondary of linear electric motors has suction mutually,,, raise the efficiency raising service life so arrange in this way and can alleviate the secondary mill body that has metal garden dish pressure so that reduce friction resistance to the ball mill rotating shaft.

Change apart from big because linear electric motors have, speed is low, so the transmission that it can press 1:1 with the mill body so the utility model can save reducing gear, makes designs simplification, easy to maintenance, the minimizing mechanism driving is lost; Simultaneously, linear electric motors have also had the big advantage of dynamicthrust, so can select the linear electric motors that mate with the normal operate power of ball mill for use, avoid low load with strong power, thereby reach aim of power saving; Above-mentioned reason also makes system effectiveness of the present utility model be greatly improved.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a side view of the present utility model.

Referring to Fig. 1, the utility model is by rotating shaft 1, steel ball 2, mill body 3, metal garden dish secondary 4, and electric motor primary 5, fixed support 7, frame 6 is formed; The metal garden coil secondary 4 with the left end welding one of mill body 3, electric motor primary 5 is coiled secondary 4 corresponding installations by fixed support 7 and metal garden, and place secondary directly over, leave certain clearance between elementary 5 and secondary 4, fixed support 7 is to stop on frame 6.

Referring to Fig. 2, electric motor primary 5 is made into four garden segmental arcs, and the garden arc of four garden segmental arc compositions is secondary concentric with metal garden dish, and it is simple that electric motor primary 5 is made, and work simplification has brought convenience to installation.
