Abstract
The utility model relates to a wet hammer fine crusher for fine crushing during roughing of low-grade iron ore, belonging to the technical field of ore dressing, which comprises a hammer crusher. The wet hammer fine crusher is characterized in that a water feeding device is arranged on a feed inlet of the hammer crusher; a stock stop is arranged at the feed inlet in a housing; a waterproof cover is arranged on a bearing; the stock stop is a chain screen, the upper end is fixed on the feed inlet of the hammer crusher, while the lower end is a free end; the water feeding device is a water inlet tube connected with an elevated water tank. The wet hammer fine crusher has the advantages that the soil mixed in the ore can be washed off using water during ore crushing due to the additional water feeding device, thereby reducing the load of the equipments of subsequent procedures and improving the productivity; the water flow enables smoother material flow in the crusher, the fine material flows away quickly, and the coarse material is fully crushed, thereby improving the productivity; the stock stop can prevent the hard material from entering in the hammer crusher, so as to protect the hammer crusher; the waterproof cover arranged on the bearing can ensure the safe operation of the bearing.
Description
Technical field
The utility model relates to the technique of preparing field, and particularly a kind of wet type hammer fine crushing machine is used for the fine crushing of low grade iron ore roughing separation.
Background technology
Along with the development of steel and iron industry,, particularly increasing to the demand of iron ore concentrate to the demand of iron ore.Because how high-grad iron ore deposit reserves resource-constrained utilizes the resourceful lean ore resource of reserves just to become the task of top priority.The technical process of development and use lean ore resource comprises the following steps: iron ore is carried out coarse crushing, fine crushing, dry separation screening, ball milling, sub-material, magnetic separation, high frequency screening, secondary magnetic separation at present, the waste residue that dry separation is sieved out is transported, the mine tailing that magnetic separation is selected is delivered to tailing dam, and fine ore is sent into the concentrate pond.This technology is applicable to that the position product are at 20% left and right sides lean ore, and for the position product when the iron ore below 15% carries out ore dressing, productivity ratio is too low, cost is too high, particularly the contraposition product can't be obtained actual economic benefit at all when the iron ore of the extremely low-grade of 4-8% is handled.Therefore must be improved existing technology and equipment.Magnetic separation in the existing technology reaches and goes on foot operation thereafter is that reasonably key is to improve the grade of going into to select materials of magnetic separator.Common hammer mill by in the charge door on casing, the casing, the casing by axle, be installed in tup on the axle, be installed in the drive at two ends of axle and beating crusher structure and the outer grate plate of tup that stabilizer is formed formed, this common hammer mill also is not suitable for a product and carries out fine crushing at the iron ore of the extremely low-grade of 4-15%.
Summary of the invention
The purpose of this utility model provides a kind of wet type hammer fine crushing machine, is used for the fine crushing of low grade iron ore roughing separation.
The purpose of this utility model realizes by following technical proposals:
Wet type hammer fine crushing machine of the present utility model, comprise hammer mill, it is characterized in that being provided with water feed apparatus on the charge door of described hammer mill, the charge door place is provided with stock stop in the casing of this hammer mill, is provided with bucker on the bearing of this hammer mill.
Described stock stop is the backgauge chain screen, and the upper end of this backgauge chain screen is fixed on the charge door of described hammer mill, and the lower end is a free end.
The water inlet pipe of described water feed apparatus for being connected with elevated tank.
Wet type hammer fine crushing facility of the present utility model have following advantage:
1, owing to set up water feed apparatus, in the process of breaking ores, the mud soil that water will be mixed in the mineral aggregate rinses out, and has therefore reduced the load of back step operation individual device, has improved operating efficiency; Simultaneously, flowing water also makes the material flow in the disintegrating machine unimpeded, and fines flows away very soon, and coarse fodder obtains sufficient fragmentation, has improved the operating efficiency of disintegrating machine;
2, owing to set up stock stop, can stop that hard material enters in the hammer mill, plays a protective role to hammer mill;
3, owing to be provided with bucker on the bearing of hammer mill, the protection bearing can trouble free service.
Description of drawings
Fig. 1 is a device structure block diagram of the present utility model.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.
As shown in Figure 1, the wet type hammer fine crushing machine that low grade iron ore roughing separation of the present utility model is used, comprise hammer mill 1, it is characterized in that on the charge door of described hammer mill 1, being provided with water feed apparatus 4, the charge door place is provided with stock stop 3 in the casing 2 of this hammer mill 1, is provided with bucker 9 on the bearing of this hammer mill 1.
Described stock stop 3 is the backgauge chain screen, and the upper end of this backgauge chain screen is fixed on the charge door of described hammer mill, and the lower end is a free end.
The water inlet pipe of described water feed apparatus 4 for being connected with elevated tank.
This wet type hammer mill 1 is by screening dispenser 6 feeds that have eccentric vibrating device 7, and the oversize 5 of screening dispenser 6 is sent into hammer mill, and spoil area is sent in minus mesh 8.Be sent to down operation through broken ore via discharging opening 10.
The thin breaker of wet type hammer type of the fine crushing for low grade iron ore roughing separation of the present utility model has following advantages:
1, owing to set up water feed apparatus, in the process of breaking ores, water will be mixed in the mineral aggregate Mud soil rinses out, and has therefore reduced the load of rear step operation individual device, has improved operating efficiency; With The time, flowing water also makes the material flow in the disintegrating machine unimpeded, and fines flows away very soon, and coarse fodder is broken fully Broken, improved the operating efficiency of disintegrating machine;
2, owing to set up stock stop, can stop that hard material enters in the hammer mill, to hammer mill Play a protective role;
3, owing to the bearing at hammer mill is provided with bucker, bearing can not intake, the protection axle Holding can trouble free service.
Claims (3)
1, a kind of wet type hammer fine crushing machine, comprise hammer mill, it is characterized in that being provided with water feed apparatus on the charge door of described hammer mill, the charge door place is provided with stock stop in the casing of this hammer mill, is provided with bucker on the bearing of this hammer mill.
2, wet type hammer fine crushing machine according to claim 1 is characterized in that described stock stop is the backgauge chain screen, and the upper end of this backgauge chain screen is fixed on the charge door of described hammer mill, and the lower end is a free end.
