Problems solved by technology

[0002] The ball mill is an important production equipment for the crushing and grinding of ore rocks in cement plants, mine concentrators, etc. During the production process of the belt conveyor that feeds ore to the ball mill in the mine concentrator, the upper belt conveys the crushed ore and enters the mill through the chute. At the mine mouth, it is inevitable that some powder ore sticks to the lower belt after unloading, and the continuous vibration of the lower belt will drop the sticky powder ore to the ground during the return journey, resulting in mine dust, which affects production civilization and sanitation. Occupational hazards are produced to the operators, and the labor of the operators to manually clean the mine dust is increased.

Embodiment 1

[0014] Example 1 like Figure 1-2 Shown: a device for removing sticky powder ore from the mill feeding belt. On the top of the chute 5 and below the unloading drive wheel 2 of the feeding belt conveyor, a pressure water pipe 9 parallel to the cross-section of the feeding belt is installed. Tee 10 is installed intermittently on the pressure water pipe 9, sprinkler 8 is installed on the tee 10, forms a row of shower nozzles 8 pointing to the lower belt 3 of the unloading drive wheel 2 of the belt feeder.

[0015] A sliding bearing seat 12 with a loam cake is installed on the top of the chute 5 , and the two ends of the pressure water pipe 9 are supported on the sliding bearing seat 12 . One end of the pressure water pipe 9 is connected to the pressure water pipe network through a sealed water pipe rotary joint 11 , and a handle 13 is installed at the other end of the pressure water pipe 9 .

[0016] Tees 10 are installed intermittently on the pressure water pipe 9, the interv...

Embodiment 2

[0017] Example 2 like Figure 1-2 Shown: adopt embodiment 1 to remove the method for removing the sticky fine ore device of the ore feeding belt of the grinding mill to remove the sticky fine ore, including:

[0018] [1] The crushed ore 1 is fed into the ore port 6 of the mill through the ore chute 5 by the ore feeding belt conveyor;

[0019] [2] Open the pressure water pipe gate valve 14 connected to the pressure water pipe network, loosen the upper cover fastening nut of the sliding bearing seat 12, turn the handle 13, adjust the angle of the pressure water flow 7 sprayed from the nozzle 8, and obtain the pressure water flow 7 to wash down After the best effect of the belt 3 sticking to the fine ore, tighten the upper cover set nut of the sliding bearing seat 12, and locate the angle at which the nozzle 8 sprays out the pressure water flow 7;

[0020] [3] The lower belt 3 with fine ore is washed away by the high-pressure water jet 7 to deposit fine ore, falls into the ore...

Abstract

The invention relates to a device and method for removing ore fines bonded to a mill ore feeding belt. The top of an ore slipping trough is provided with a pressure water pipe parallel to the cross section of the ore feeding belt. Tee joints are arranged on the pressure water pipe intermittently at intervals, the tee joints are provided with spray nozzles, and a row of the spray nozzles pointing to the lower belt is formed. The interval of every two adjacent tee joints ranges from 15 cm to 20 cm. The distance between the spray nozzles and the lower belt ranges from 20 cm to 30 cm. The mounting angle a of the spray nozzles ranges from 45 degrees to 55 degrees. The water jet pressure p ranges from 0.4 Mpa to 0.6 Mpa. A pressure water pipe sluice valve connected with a pressure water pipe network is opened, and the angle of the pressure water flow sprayed out by the spray nozzles is adjusted so as to achieve the optimal effect that the pressure water flow flushes the ore fines bonded to the lower belt. The device and method have the advantages that the structure is simple and practical, the cost is low, and mounting is convenient to conduct; no drive device exists, and the operation cost is low; the maintenance workload is extremely low.

Description

technical field [0001] The invention relates to an auxiliary device and process for mineral dressing production in mines, in particular to a device for removing sticky powder ore from a mill feed belt and a method for removing powder ore. Background technique [0002] The ball mill is an important production equipment for the crushing and grinding of ore rocks in cement plants, mine concentrators, etc. During the production process of the belt conveyor that feeds ore to the ball mill in the mine concentrator, the upper belt conveys the crushed ore and enters the mill through the chute. At the mine mouth, it is inevitable that some powder ore sticks to the lower belt after unloading, and the continuous vibration of the lower belt will drop the sticky powder ore to the ground during the return journey, resulting in mine dust, which affects production civilization and sanitation. Occupational hazards are produced to the operating personnel, and the labor of the operating person...
