The composition of the ball mill for the dry powder grinding mill comprises a motor (1); the motor is connected with a speed reducer (2); the speed reducer is connected with a rotating shaft of a drum-type separating screen (4); the rotating shaft is arranged on a supporting device (3); the lower part of the drum-type separating screen is provided with a circular groove liner plate (12); the discharge end of the drum-type separating screen is provided with a discharge cavity; a material throwing hole (10) is formed in the discharge cavity; an outlet of the discharge cavity is provided with an aggregating cover (9); the discharge cavity is connected with a discharge grate (7) arranged in the drum-type separating screen; the other end of the discharge cavity is provided with a feeding device (6). The ball mill for the dry powder grinding mill is used for super-fine grinding of ores.
Description
technical field:
the present invention relates to a kind of dry powder abrading-ball grinding machine.
background technology:
the shortcoming that the ball mill of common Super-fine grinder exists is mainly reflected in the following aspects: 1. the screening chamber of common Super-fine grinder be one section along grinding mill barrel internal diameter, wide 30mm hoop space, ball storehouse mill is little steel ball or bulk materials are easy to enter screening chamber and block, and affect screening efficiency; 2. the screening of Super-fine grinder depends on built-in 16 " vertical sieve plates ", and material completes from material charge level is poor in the mobile dependence mill in Dao Duan storehouse, ball storehouse, is a kind of " static state " screening; 3. common Super-fine grinder sieving plate is planar structure, is easy to distortion and damaged.
summary of the invention:
the object of this invention is to provide a kind of dry powder abrading-ball grinding machine.
above-mentioned object realizes by following technical scheme:
a kind of dry powder abrading-ball grinding machine, its composition comprises: motor, described motor is connected with reductor, described reductor is connected with the rotating shaft of drum-type separating sieve, described rotating shaft is arranged on bracing or strutting arrangement, described drum-type separating sieve bottom is provided with circular groove liner plate, the discharge end of described drum-type separating sieve is provided with discharging chamber, in described discharging chamber, be provided with and get rid of material hole, in described discharging chamber outlet, be provided with the cover that gathers materials, described discharging chamber is connected with the discharging grate plate in being arranged on described drum-type separating sieve, the described discharging chamber other end is provided with feed arrangement.
described dry powder abrading-ball grinding machine is provided with manhole on described discharging chamber.
beneficial effect:
the screening chamber of common Super-fine grinder be one section along grinding mill barrel internal diameter, ，Qiu storehouse, wide 30mm hoop space mill little steel ball or bulk materials be easy to enter screening chamber and block, affect screening efficiency, and the present invention is without this defect sturcture.
2. what the present invention adopted is drum-type separating sieve, and material moves on cylinder separating sieve, is carrying out constantly sorting simultaneously, is therefore the sorting of a kind of " dynamically ", and the efficiency of separation is higher.
3. separating sieve of the present invention is stereochemical structure, is difficult to distortion and damages.Device for feeding fish bait feedstuff feeding deficiency or the excessive problem of feedstuff feeding have in the past been solved.
4. the radially vertical circular groove liner plate designing in separating sieve of the present invention, has cancelled the blind plate in common Super-fine grinder, sticks with paste ball, sticks with paste section, improper ventilation is particularly favourable to solving in long grinding machine grinding process.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present invention.In figure, 11 is crushing medium.
the specific embodiment:
embodiment 1:
a kind of dry powder abrading-ball grinding machine, its composition comprises: motor 1, described motor is connected with reductor 2, described reductor is connected with the rotating shaft of drum-type separating sieve 4, described rotating shaft is arranged on bracing or strutting arrangement 3, described drum-type separating sieve bottom is provided with circular groove liner plate 12, the discharge end of described drum-type separating sieve is provided with discharging chamber 8, in described discharging chamber, be provided with and get rid of material hole 10, in described discharging chamber outlet, be provided with the cover 9 that gathers materials, described discharging chamber is connected with the discharging grate plate 7 in being arranged on described drum-type separating sieve, the described discharging chamber other end is provided with feed arrangement 6.
embodiment 2:
dry powder abrading-ball grinding machine according to described in embodiment 1 is provided with manhole 5 on described discharging chamber.
embodiment 3:
described dry powder abrading-ball grinding machine, the meal that common closed circuit mill is selected due to powder concentrator enters ball storehouse, and the impact of ball is formed to buffering effect, has weakened the breaking capacity of ball, affects the performance of mill output.And there is the strict division of labor in He Duan storehouse, sorting abrading-ball storehouse, ball storehouse main " breaking ", forges storehouse main " mill ", and built-in separation system can be selected the fine powder in ball storehouse send in time and forge storehouse, improves broken, the mill efficiency in Ji Duan storehouse, ball storehouse.Under same working condition, minute selective grinding is cancelled the production of powder concentrator open circuit, guarantees out mill cement specific surface area >=340 ㎡/㎏, and output is not less than former closed circuit mill output.The production technology relative complex of closed circuit mill, needs a powder concentrator and 2～3 lifting conveying equipments, therefore need provide a large amount of electric energy to support the normal operation of these equipment.And minute selective grinding is produced for open circuit, built-in material separation system need not additionaling power.The closed circuit mill of φ 2.4 * 8m of take is example, and the main motor 75kw of powder concentrator adds and promotes and conveying equipment total installation of generating capacity 100kw left and right, 950 yuan of transformation rear every day of power cost savings, 300,000 yuan of left and right of annual cost.Cement granules level pairing cement performance has the following granule content of direct impact, particularly 32um to play a major role to gain in strength, and the cement granules that is greater than 65um is difficult to aquation, and activity is very little preferably not to be had.Divide selective grinding can improve cement granules grating, improve Cement Quality.The closed circuit grinding machine of φ 2.4 * 8m of take is example; cement products before and after transformation is sampled respectively, and test result is as follows: before transformation, fineness controls≤3%, and output is in 20t/h left and right; the following cement granules cumulative distribution of 32um is 54.93%, and the cement granules cumulative distribution that is greater than 65um is 21.98%; After transformation, under same working condition, fineness controls≤4%, and output is in 22t/h left and right, and the following cement granules cumulative distribution of 32um is 99.99%, and the cement granules that is greater than 65um is 0.Three days intensity of cement is on average carried 4.7Mpa.Due to closed-circuit grinding system technique relative complex, equipment increases, and human and material resources, financial resources consumption are can hardly be avoided.Cancel after powder concentrator, simplified technological process, operation rate increases substantially.Owing to forging storehouse mainly to be ground to master, good material is selected in micro-forging in addition, and the consumption of micro-forging is quite low, approximately 30 grams of/ton of cement left and right; The impulsive force of micro-forging is little, thereby also corresponding reducing of the wearing and tearing of forging storehouse liner plate.
