Problems solved by technology

The requirement for the uniformity of external feeding is high. Once the external feeding is too much, it is easy to cause material blockage. If the external feeding is small, there will be a shortage of material, which will affect the production efficiency.
After the feeder wears out and fails, it needs to be replaced as a whole

Embodiment 1

[0019] Example 1 Such as Figure 1-5 Shown: A ball mill drum feeder, which is composed of a cylindrical feeding shell 5, a feeding end cover 6 matched with it, a bottom lining plate 12 and a three-port spiral body 7; 5. The bottom lining plate 12 and the three-port spiral body 7 matched with the inner cavity are loaded into the open end of the cylindrical feeding shell 5, and the feeding end cover 6 is connected to the cylinder through the 2# bolt 8, the spring washer 9 and the 2# nut 10. Tightly connect the bottom liner 12 and the three-port spiral 7 with the inner bottom of the cylindrical feed shell 5; the center of the bottom of the cylindrical feed shell 5 is provided with a circular material outlet WC and the boss and mounting screw hole that are connected with the inlet end cover of the ball mill; the three-port spiral body 7 is an integral wear-resistant casting composed of three helical blades 13 in an annular array, and enters from the material inlet WR of the feed...

Embodiment 2

[0022] Example 2 Such as Figure 1-5 Shown: Using Example 1 Place Describe a kind of feeding method of ball mill drum feeder, comprising:

[0023] ① After the ball mill starts, start the belt conveyor to feed the drum feeder;

[0024] ② Every time the barrel of the ball mill rotates one turn, the three-port screw (7) of the drum-shaped feeder fixedly connected to the inlet end cover of the ball mill feeds the material to the ball mill three times. Improve the production efficiency of the ball mill;

[0025] ③ Before the ball mill stops running, first stop the belt conveyor for conveying materials.

Abstract

The invention relates to a drum-shaped feeder of a ball grinding mill. A lining plate matched with an inner cavity of a cylindrical feeding shell and a three-mouth spiral body are loaded from an open end of the cylindrical feeding shell, a feeding end cover is tightly connected with the cylindrical feeding shell by bolts, a circular material outlet WC, a boss in matching connection with an inlet end cover of a ball grinding mill and an installation screw hole are arranged in the center of the bottom of the cylindrical feeding shell, and the three-mouth spiral body is an integral wear resistance casting composed of three spiral blades in an annular array. The feeding method of the drum-shaped feeder is characterized in that the three-mouth spiral body of the drum-shaped feeder fixedly connected with the inlet end cover of the ball grinding mill feeds the ball grinding mill in three times with each turn of a cylinder body of the ball grinding mill, feeding is uniform and smooth, outage maintenance caused by extrusion blocking of the material is completely eradicated, and the production efficiency of the ball grinding mill is improved. The three-mouth spiral body, the lining plate and the shell are dismountable, and maintenance is convenient. Only the three-mouth spiral body and the lining plate need to be replaced after wear-out failure, the feeding shell can be used continuously, and the cost is saved.

Description

technical field [0001] The invention relates to crushing equipment of a mineral processing plant, in particular to a ball mill drum feeder and a feeding method thereof. Background technique [0002] The existing feeder is an integral type with only one material inlet. The material guiding process is long, and the material can only be introduced once when the cylinder rotates once. The requirement for the uniformity of the external feeding is high. Once the external feeding is too much, it is easy to cause a material blockage. If the external feeding is small, there will be a shortage of material, which will affect the production efficiency. After the feeder wears out and fails, it needs to be replaced as a whole. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a detachable drum-shaped feeder and its feeding method that fully utilizes the inner space of the feeder and can adapt to large changes in external feedin...
