Abstract
The utility model discloses a single axle dual-roll high pressure grinder, composed of a fixed roller, a movable roller, a frame used to support the two rollers, a drive device and a pressure system. Under the cooperation of a special feeding device and using the roughness and the compressibility of the powder material, the pure pressure crushing can be achieved only by one drive device. Compared with the double-drive device, the utility model has the advantages of simple structure, low cost and low energy consumption. The productivity can be increased about 10%. The utility model is applicable to the grinding of the powder brittle material such as the cement, the ore, the coal, etc.
Description
The utility model is a kind of comminution equipment of diffusing shape brittle material.
The two roller high pressure grinders of two drive-types that the Germany is released in recent years, all use identical transmission and the deceleration system of two covers, the stationary roll and the mobile rollers that it is characterized in that being bearing on the frame are all come transmission by direct current generator and mechanical reduction gear, and high pressure is provided by hydraulic system.Breathe out in April, 1986 in first world's particle technology meeting that Nuremberg, Federal Germany is held, and gram is reined in the article of getting over Sai Er and introduced this up-to-date efficient low-consume energy-saving equipment.But this device structure complexity requires height to two synchronisms of overlapping the transmission deceleration component, and wherein a cover also must move with the adjustment in gap, the poor requirement that strictness is arranged in roller footpath of two working rolls, and general roller is poor being limited in 1% directly.
The purpose of this utility model is the two roller high pressure grinders of a kind of single-driving type of design, and the simplified apparatus structure reduces cost, overcomes the poor influence in roller footpath, further increases work efficiency, and saving the comminution energy consumption increases the fine fraction productive rate.
The two roller high pressure grinders of single-driving type of the present utility model mainly drive stationary roll 3 runnings by variable-speed motor 1 by gear reduction system 2, support the bearing 5 of stationary roller shaft 4 to be fixed on the frame 6, be bearing on the bearing 9 with the roll shaft 8 of stationary roll in the mobile rollers 7 of same axial plane, this bearing is assemblied on the slide block 10, slide block can be along axial plane parallel moving on rack rail 11, slide block links to each other with pressure apparatus 12, and the device that pressure is provided can be spring system or hydraulic system.The side lower edge 14 that wedge shape funnel 13 is vertical with the roller axis direction is arcs, and is identical with smooth roll surface 15,16 maintenances of two rollers; The lower edge 18 of the funnel side 17 that parallels with two roll axis directions is rectilinear, keeps coincideing with roll surface, and whole funnel has limited the overall movement trend of bulk material 19.When stationary roll is driven running, force material to move downward by the gap between two rollers 20, the pressurized comminution, final crushed products becomes material cake 21 and discharges.
Characteristics of the present utility model are that the shape brittle material that looses must keep certain height in funnel, and material enters two roller gaps continuously with dense state, and material more down compression ratio is bigger between roll gap, suffered pressure is also bigger.By mobile rollers under the effect of pressure apparatus, make mobile rollers and stationary roll keep certain pressure, the roughening and the compressibility of shape brittle material owing to loose, mobile rollers is under frictional drive, rotate with stationary roll, two roller rollers footpaths poor less than 5% scope in two roller linear velocities keep good homogeneity, comminution is carried out under high efficiency compression condition.According to the property difference of material, the intensity of regulating pressure apparatus adapts to concrete condition.
The two roller high pressure grinders of single-driving type of the present utility model are the improvement to the two roller high pressure grinders of two drive-types, changed and it is believed that and to eliminate additional the shearing, keep two rollers to have identical linear velocity, realize pure pressure breaking, must reduce the custom view that the poor method in two roller rollers footpath just can be accomplished by adjusting two gearratios that drive.The utility model is roughening and a compressibility of utilizing the shape brittle material that looses, relies on rubbing action to come another roller of transmission when the high pressure comminution, just can realize pure pressure breaking; When two rollers exist the roller footpath poor, still can keep same linear velocity, overcome additional harmful effect of shearing.The two roller high pressure grinders of single-driving type make designs simplification, and configuration is convenient.Cost reduces, and compactness is installed, must often repair for the roller footpath of double-working is poor, reduces maintenance cost.Can further reduce the comminution energy consumption, increase the fine fraction productive rate.To cement, the comminution of the diffusing shape brittle material of industries such as ore and coal has very big practical value.
Description of drawings:
Fig. 1 is the two roller high pressure grinder vertical views of single-driving type.Wherein 1 is variable-speed motor, and 2 is gear reduction system, and 3 is stationary roll, and 4 is stationary roller shaft, and 6 is frame, and 7 is mobile rollers, and 8 is movable roll shaft.
Fig. 2 is the two roller high pressure grinder left views of single-driving type.Wherein 5 is the bearing of stationary roller shaft, and 9 is the bearing of movable roll shaft, and 10 is slide block, and 11 is guide rail, 12 is pressure apparatus, and 13 is that wedge shape funnel, 14,18 is the funnel edge, and 15,16 is smooth roll surface, and 17 is the funnel side, 19 is bulk material, and 20 is two roller gaps, and 21 are material cake product.
Embodiment:
The enforcement of the two roller high pressure grinders of single-driving type can be divided into two kinds of situations.At 500mm, following can use variable-speed motor for the roller footpath, and belt and belt pulley cooperate transmission, and pressure apparatus then uses spring system; Cooperate transmission for can the use variable-speed motor and the gear reduction system of roller footpath more than 500mm, pressure apparatus then uses hydraulic system.Single drive roll that drives can be any roller in two rollers in principle, but more suitable to drive stationary roll.Aborning during the poor 1-5% of appearance in two roller rollers footpaths still operate as normal need not repair.
With the comminution lead-zinc ore is example.At first regulate the required pressure value of this ore of adaptation, make ore under the duty of roller mill, pass through the stressed zone, can change pressure into the pulverizing energy effectively, obtain comminution material cake.Be in operation, the two roller high pressure grinder operational excellences of single-driving type, two roller speed are synchronous.Compare under same mineral and operating condition with the two rollers of two drive-types, single drive ratio is two to be driven and produces-100 order product specific energy consumptions and reduce approximately 10%, and the productive rate of-100 order products increases more than 10%.
