Description

Test ball mill

Technical Field

The utility model relates to an experimental ball mill belongs to the test equipment field.

Background

The ball mill is the key equipment for crushing the materials after the materials are crushed. It is widely used in the production industries of cement, silicate products, novel building materials, refractory materials, chemical fertilizers, black and non-ferrous metal ore dressing, glass ceramics and the like, and is used for dry or wet grinding of various ores and other grindable materials. The ball mill is suitable for grinding various ores and other materials, is widely used in the industries of mineral separation, building materials, chemical industry and the like, and can be divided into a dry type ore grinding mode and a wet type ore grinding mode. According to different ore discharge modes, the method can be divided into a lattice type and an overflow type.

The ball mill is composed of horizontal cylinder, hollow feeding and discharging shaft and grinding head, the cylinder is long cylinder, the grinding body is installed in the cylinder, the cylinder is made of steel plate, and is fixed with the cylinder by steel lining plate, the grinding body is generally steel ball, and is loaded into the cylinder according to different diameters and a certain proportion, the grinding body can also be steel section. The material is selected according to the granularity of the grinding material, the material is loaded into the barrel body from the hollow shaft at the feeding end of the ball mill, when the ball mill barrel body rotates, the grinding body is attached to the lining plate of the barrel body and taken away by the barrel body under the action of inertia and centrifugal force and friction force, when the grinding body is taken to a certain height, the grinding body is thrown off under the action of the gravity of the grinding body, and the falling grinding body breaks the material in the barrel body like a projectile body.

The materials are fed into the first bin of the mill by a feeding device through a hollow shaft, and the bin is internally provided with a stepped lining plate or a corrugated lining plate which is internally provided with steel balls of various specifications, and the steel balls are driven to fall down after being driven to a certain height by the centrifugal force generated by the rotation of a cylinder body, so that the materials are impacted and ground. After the material reaches rough grinding in the first bin, the material enters the second bin through the single-layer bin partition plate, the flat lining plate is inlaid in the bin, the steel ball is arranged in the bin, and the material is further ground. The powder is discharged through the discharging grate plate to finish the grinding operation.

For the ball mill for the test, the defects of complex equipment structure, easy slipping of grinding balls, low ball milling efficiency and the like exist.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides an experimental ball mill, simple structure, the ball is difficult to skid, and ball-milling efficiency is high.

The utility model discloses an above-mentioned technical problem is solved to following technical means:

the utility model discloses an experimental ball mill, it includes the barrel, is provided with the bung on the barrel, is fixed with the back shaft on the barrel both ends, and the back shaft passes through bearing and leg joint, is fixed with the gear on one of them back shaft, and the gear setting is in the gearbox, and the gearbox is connected with the motor.

The thickness of the steel plate of the cylinder body is 10 mm.

24 reinforcing steel bars are uniformly welded in the cylinder body, and the size of each reinforcing steel bar is phi 20x600 mm.

The barrel body is connected with the barrel cover through an M10 bolt, and a rubber pad is clamped in the middle.

The power of the motor is 1.5kw, and the motor is a variable frequency motor.

The cylinder is sealed as a whole.

The grinding balls are arranged in the cylinder body.

Traditional ball mill, generally adopt fixed gear on the barrel perisporium, then the rotation of barrel is realized to rethread drive gear, and this patent adopts and is fixed with the back shaft on the barrel both ends, the back shaft passes through bearing and leg joint, be fixed with the gear on one of them back shaft, the gear setting is in the gearbox, the gearbox is connected with the motor, it rotates to drive the gearbox through the motor, thereby drive gear revolve, it rotates to drive the barrel again, evenly weld has 24 reinforcing bars in the barrel simultaneously, the size of reinforcing bar is phi 20x600mm, the barrel rotates, because blockking of reinforcing bar, can avoid skidding of ball and material, the ball-milling is efficient.

The utility model has the advantages that: simple structure, the ball-milling is difficult to skid, and the ball-milling is efficient.
