Description
Technical field
The utility model relates to a kind of multiple roll pulverizer, belongs to the mine field of metallurgical machine.
Background technology
Pulverizer is mainly used in the pulverizing of ore, is the requisite equipment of industry such as metallurgy, cement.The granularity of the reliable break mined material of existing pulverizing function is generally the 10-20 millimeter, 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 mainly to be 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 the steel ball, between steel ball and the liner plate.
Summary of the invention
The purpose of this utility model provides the multiple roll pulverizer that energy consumption is low, efficient is high, the comminution of minerals granularity is little.
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, it is characterized in that: being provided with horizontal grinding roller at the top of fixed frame is, horizontal grinding roller is to be made of horizontal grinding roller more than two, the roll shape of horizontal grinding roller is the circular arc of indent, the roll shape of each horizontal grinding roller of the horizontal grinding roller of formation system is encircled into a circular hole, the power that horizontal grinding roller is is input as each horizontal grinding roller independent input power, or one of them horizontal grinding roller is as the power input roller, the intermeshing gear transmission of other horizontal grinding roller by being installed in each grinding roller axle head be by the power of power input roller input, the center of circle direction rotation of the circular hole that each the horizontal grinding roller in the horizontal grinding roller system all is encircled into to each roll shape; Movable machine frame is installed on the interior horizontal stand of fixed frame, between movable machine frame and fixed frame, be provided with the guiding mechanism of vertical direction, at the movable machine frame middle part roll mill roller is installed, the roll mill roller top is that domed bottom is the rotary body that cylindrical middle connection is become by an easement curve, roll mill roller top half radius of a ball is identical with the roll shape circle hole radius that horizontal grinding roller is, and roll mill roller top hemisphere stretches in the roll shape circular hole of horizontal grinding roller system, is provided with movable machine frame at the horizontal stand of the bottom of movable machine frame and fixed frame and locates and pressure-regulating device.
The utility model has the advantages that: adopt multiple roll in the mode of extruding, shearing grinding mineral to be carried out the dry type pulverizing and effectively realized industrialization that reliably the mineral with 10～20 millimeters directly are crushed to 0～1 millimeter; Energy-saving effect is obvious, compares with ball mill to can save energy 50 percent; Water-saving result is obvious, 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 the Tailings Dam use procedure; Use reliably, because there is not the inhomogeneous problem of roller surface wearing and tearing in the utility model structural principle, also can not occur owing to the grinding roller wearing and tearing affect the underproof problem of grinding charge material output granularity.
Description of drawings
Fig. 1 is the structural representation that horizontal grinding roller of the present utility model is two rollers;
Fig. 2 is the schematic diagram that the horizontal grinding roller of two rollers system cooperates with roll mill roller;
Fig. 3 is the structural representation of the horizontal grinding roller of three rollers system.
The specific embodiment
With reference to accompanying drawing 1,2, it is three roller pulverizers of two rollers that a kind of horizontal grinding roller is provided in the accompanying drawing, comprise fixed frame 1, movable machine frame 2, horizontal grinding roller is 3 to be located at the top of fixed frame 1, the axle of two horizontal grinding rollers is fixed with fixed frame 1 top by bearing and bearing block 4, the roll shape 11 of horizontal grinding roller is the circular arc of indent, the axis of two horizontal grinding rollers of the horizontal grinding roller of formation system be arranged in parallel, its roll shape is encircled into a circular hole 12, an axle head at each horizontal grinding roller is provided with a power input mechanism 6, power input mechanism 6 is belt pulley, sprocket wheel or gear, horizontal grinding roller are the center of circle direction rotation of the circular hole that all is encircled into to its roll shape of two horizontal grinding rollers in 3; Movable machine frame 2 is installed on the horizontal stand in the fixed frame 1, be provided with movable machine frame location and pressure-regulating device 8 in the bottom of movable machine frame and the horizontal stand of fixed frame, on horizontal stand, be provided with symmetrically vertical guide stem 10, movable machine frame is provided with the gathering sill 9 that cooperates with vertical guide stem 10, gathering sill 9 cooperates with vertical guide stem 10 and defines movable machine frame and can only move in vertical direction, at the movable machine frame middle part roll mill roller 5 is installed, the axle of roll mill roller 5 is fixed by bearing and movable machine frame, the roll mill roller top is that domed bottom is the rotary body that cylindrical middle connection is become by an easement curve, roll mill roller top half radius of a ball is identical with roll shape circular hole 12 radiuses that horizontal grinding roller is, and roll mill roller top hemisphere stretches in the roll shape circular hole 12 of horizontal grinding roller system, and the power input mechanism 7 of roll mill roller is located at the axle head of roll mill roller.
