The ball plate mill is characterized in that the bottom of a lower framework of the movable rack is mounted on a horizontal rack in the fixed rack via an elasticity supporting device; locating devices connected with the inner wall of the fixed rack are symmetrically formed at the periphery of the lower framework of the movable rack; a horizontal shaft is formed at the upper part of the movable rack via a bearing; the milling ball is mounted on the horizontal shaft, and an axis of the horizontal shaft passes through the centre of the milling ball; a power input device is formed at one end of the horizontal shaft; the inner surface of the milling plate is an arc surface matched with the milling ball; a hollow rotary vertical shaft is mounted at the top of the fixed rack via the bearing; the lower part of the hollow rotary vertical shaft is connected with the symmetrical centre of the milling plate; and the power input device is formed at the upper part of the hollow rotary vertical shaft. The ball plate mill disclosed by the utility model has the advantages of achieving dry ore milling, having low energy consumption, high efficiency, long service life and small granularity of crushed ore and solving the problem that a dry ball mill cannot discharge materials without a draught fan.
Description
Technical field
The utility model relates to a kind of ball disc mill, belongs to the mine field of metallurgical machine.
Background technology
The ball disc mill is a kind of mine size reduction machinery, and the mine is mainly used in the pulverizing of ore with pulverizer, is the requisite equipment of industry such as metallurgy, cement.The granularity of the reliable break mined material of existing pulverizing function is generally 10-20 millimeters, and the size reduction machinery (can reach suitability for industrialized production) that is crushed to below 1 millimeter is in space state substantially.And existing ball mill exists energy consumption high, and efficient is low, and the milling medium consumption is large.The energy consumption high efficiency is low is mainly because most energy provide kinetic energy to milling mediums such as steel balls in the process of comminution of minerals, and the steel ball that obtains kinetic energy is impacting, is having the considerable part energy effectively not act in the grinding mineral process to treat the ore grinding thing, but has lost with the forms such as impact friction between steel ball, between steel ball and liner plate.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcomings such as traditional ball mill energy consumption is high, efficient is low, the medium abraded quantity is large, Cai provide a kind of adopt the ball dish with extruding, shear grinding mode to mineral carry out dry milling, but energy consumption is low, efficient is high, the life-span is long, the comminution of minerals granularity is little, can solve the ball disc mill that dry ball must be utilized the problem of air-introduced machine discharge.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
The utility model comprises fixed frame, movable machine frame, mill, abrading-ball, it is characterized in that: the lower frame bottom of movable machine frame is arranged on horizontal stand in fixed frame by the resilient support device, lower frame periphery at movable machine frame is symmetrically arranged with the positioner that is connected with the inwall of fixed frame, top at movable machine frame is provided with trunnion axis by bearing, abrading-ball is arranged on trunnion axis, and the axis of trunnion axis passes the center of abrading-ball, is provided with power input device at an end of trunnion axis; The inner surface of mill is the arc surface that coordinates with abrading-ball, by bearing, hollow rotary vertical shaft is installed at the top of fixed frame, and the bottom of hollow rotary vertical shaft connects the symmetrical centre of mill, and the top of hollow rotary vertical shaft is provided with power input device.
Described abrading-ball is mutually vertical with the direction of motion of mill;
Described resilient support device is made of puller bolt and spring;
Described positioner is made of bracing frame and the roller that is arranged on bracing frame;
Described roller is against on the lower frame sidewall of movable machine frame.
The utility model has the advantages that: effectively realized to industrialization reliably dry milling; Energy-saving effect is obvious, compares with ball mill to can save energy 50 percent; Water-saving result is obvious, and the utility model is that dry operation can be saved a large amount of ore grinding waters; More can greatly reduce ore grinding and mill water amount for magnetic mineral the utility model and dry-type magnetic extractor integration of operation, also reduce greatly the risk in Tailings Dam construction scale and scale of investment and Tailings Dam use procedure; Use reliably, due to the utility model type structural principle, do not have the inhomogeneous problem of roller surface wearing and tearing, also can not occur because the grinding roller wearing and tearing affect the underproof problem of grinding charge material output granularity; Having overcome dry grinding mill must utilize the air-introduced machine to carry out discharge and the shortcoming that consumes a large amount of electric energy.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that A-A of Fig. 1 is to cutaway view.
The specific embodiment
With reference to accompanying drawing 1,2, the utility model comprises fixed frame 9, movable machine frame 4, mill 1, abrading-ball 2, the lower frame bottom of movable machine frame 4 is arranged on horizontal stand 12 in fixed frame by symmetrically arranged eight resilient support devices, lower frame periphery at movable machine frame is symmetrically arranged with four positioners 5 that are connected with the inwall of fixed frame, top at movable machine frame is provided with trunnion axis 8 by bearing, abrading-ball 2 is arranged on trunnion axis 4, and the axis of trunnion axis passes the center of abrading-ball, is provided with belt pulley 3 at an end of trunnion axis; The inner surface of mill 1 is the arc surface that coordinates with abrading-ball, by bearing, hollow rotary vertical shaft 10 is installed at the top of fixed frame, and the bottom of hollow rotary vertical shaft 10 connects the symmetrical centre of mill 1, and the top of hollow rotary vertical shaft 10 is provided with belt pulley 11.Described resilient support device is made of puller bolt 7 and spring 6, by regulating puller bolt 7, movable machine frame 4 is moved up and down, and makes abrading-ball 2 and mill 1 reach best fiting effect; Described positioner is made of bracing frame and the roller that is arranged on bracing frame, and roller is against on the lower frame sidewall of movable machine frame, and movable machine frame is played position-limiting action, makes movable machine frame to vertically move, can not transverse shifting.
Crushing process of the present utility model is: material enters between mill 1 and abrading-ball 2 from the hollow part of hollow rotary vertical shaft 10, the power of mill 1 is by belt pulley 11 inputs on hollow rotary vertical shaft top, horizontally rotate, the power of abrading-ball 2 is by belt pulley 3 inputs of trunnion axis one end, make vertical rotary, independent revolution separately, its both gyratory directions is mutually vertical.Mill and abrading-ball strong vertical extruding, shearing, friction and grinding will be subject to simultaneously for the material that enters between mill and abrading-ball.Whole crushing process is namely the positive feed process, also is to force the discharge process.The resilient support device of movable machine frame bottom will be regulated the operating pressure between mill and abrading-ball effectively.
