The technical solution of the utility model is achieved in that this improved vertical ore is to roller mill, form by feed hopper, discharging opening, motor and Hydraulic Station oil pump driving grinding pair roller that frame is provided with, manyly be arranged on the frame grinding the pair roller hierarchical composition, grind the pair roller setting and be the ladder distribution, it is characterized in that: grind the pair roller adjustable gaps, every grade is ground pair roller a stationary roll and a mobile roller is set, gap from top to bottom reduces gradually, and grinder is provided with a plurality of hydraulic cylinders that Hydraulic Station is provided with on the drive chassis respectively and adjusts many workplace distances to mixing roll.
Described improved vertical ore is to roller mill, and described hydraulic cylinder is arranged at the side of mobile mixing roll bearing block on the frame, and bearing block and frame are slidingly connected.
Described improved vertical ore is to roller mill, and described bearing block is provided with top board and is connected with hydraulic cylinder.
Described improved vertical ore also is provided with adjusting nut to roller mill between the described mixing roll.Described improved vertical ore is to roller mill, and described every grade of grinding pair roller lower tilt is provided with the ore pulp sieve, and screenings enters the ore pulp passage and arrives discharging opening, and oversize enters next stage and grinds pair roller.
Described improved vertical ore is to roller mill, and two roller speed of described grinding pair roller do not wait, and direction is relative, and grinding two roller speed ratios of pair roller is 1: 1.8.
Described improved vertical ore is to roller mill, and described each grade grinds pair roller top spraying cooling water pipe is set, and the ore pulp sieve is gone up to be provided with and dashed the material water pipe.
The improved vertical ore of the utility model is to roller mill, motor-driven oil pump and mixing roll are set to rotate and finishes the in small, broken bits of ore, in process in small, broken bits, carry out sizing screening, make the ore pulp that reaches granularity requirements see through sieve and be flushed to the ore pulp discharging opening, ore pulp enters next stage and grinds pair roller continuation grinding on the sieve; The hydraulic cylinder of Hydraulic Station control is simultaneously in time adjusted the gap of each grade mixing roll, guarantees Grinding Quality, therefore can increase work efficiency greatly, and simple in structure easy to use, application prospect is very wide.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Among the figure: 1, frame 2, feed hopper 3, fender plate 4, spraying cooling water pipe 5, adjusting nut 6, mobile roller 7, hydraulic cylinder 8, stationary roll 9, dash material water pipe 10, ore pulp sieve 11, ore pulp passage 12, discharging opening 13, bearing block 14, top board
The specific embodiment
Be example with improved vertical ore to the structural representation and the course of work of roller mill below, embodiment of the present utility model be described:
The utility model adopts the motor-driven hydraulic oil pump, and the high-pressure and hydraulic oil of oil pump output drives stationary roll 8 and mobile roller 6 rotates, and the rotating speed of pair roller can be regulated by the handle that unscrews of automatic variable plunger displacement pump, increases discharge capacity, and rotating speed increases, otherwise rotating speed reduces.Each is 1: 1.8 to the roller speed ratio, forms soon at a slow speed poor, makes material enter discharge smoothly like this and can reach effect in small, broken bits again.Innovative point of the present utility model is the hydraulic cylinder 7 of Hydraulic Station grading control to be set with the grinding gap of the mobile roller 6 of timely adjustment with stationary roll 8, to prevent causing grinding the gap increase because of the wearing and tearing of mixing roll.Concrete technical scheme is in the side of mobile roller 6 bearing blocks 13 top board 14 to be set, and hydraulic cylinder 7 withstands on the top board, also is provided with adjusting nut 5 with the distance between the default mixing roll between two mixing rolls; Feed hopper 2 is set above frame 1, and a shaft is equipped with in the feed hopper bottom, the material that enters in the feed hopper 2 is stirred enter first group of mixing roll.Above between every group of pair roller, there are spraying cooling water pipe 4 flowing water to cool off.Material first group and the second group ore pulp sieve 10 that grinds between the rod in casing that ground through the first road mixing roll carries out sizing screening, and sieve adopts stainless steel wire to make, and its gradient adjustable size is keeped in repair very convenient.After the screening, the powder that reaches the requirement granularity enters anti-direct current magnetic separator by ore pulp passage 11 from discharging opening 12, the powder that does not reach the requirement granularity enters second group of mixing roll, gap between second group of grinding roller is littler than first group of grinding roller gap, can will not have material in small, broken bits further in small, broken bits, and is the same through the ore pulp sizing screening, the powder that does not reach the requirement granularity enters the 3rd group of grinding roller, the 3rd group of grinding roller gap is smaller, and the rest may be inferred, reaches granularity requirements until ore pulp is progressively ground.The utility model selects three grades to grind pair roller, also can take the circumstances into consideration increase and decrease according to concrete ore pulp situation in the practical application.
The improved vertical ore of the utility model is to roller mill; can reduce and shut down the adjustment time; obviously play energy-conservation, high-quality and efficient effect; traditional ball mill is under the driven by motor of 475kw; production efficiency can only reach 16-29t/h; and the utility model can reach 16-230t/h according to each department ore different in kind production efficiency under the driven by motor of 95kw, has saved electric energy greatly, has improved efficient.The utility model frame is detachable, and vertical structure can reduce floor space, maintenance and convenient transportation.
The utility model listed examples is intended to further illustrate combination and the application mode of this improved vertical ore to roller mill, and scope of the present utility model is not constituted any restriction.
