Abstract

The utility model relates to a ball grinding machine which is suitable for being used in the mineral separation on the mine, and the crude material ball grinding and the clinker ball grinding in the cement production. The improvement is performed to the prior ball grinding machine, the shaped of an expansion cylinder is designed into a frustum shape, and the bearing shell on the original expansion cylinder bracket is changed into the bearing connection. Because the frustum-shaped expansion cylinder is adopted, the expansion cylinder and the liner plate fixed on the inner wall of the expansion cylinder are not parallel with the shaft line of the expansion cylinder. When the ball grinding machine rotates, the steel ball in the expansion cylinder can be uniformly distributed, the big block materials can not be easy to be rolled towards the discharging opening end, hence, the ball grinding is abundant, the material escaping phenomenon can not be generated, and the manpower and the material resources can be saved; because the expansion cylinder shaft is changed into the bearing connection, the frictional resistance can be reduced, and the electricity consumption is low.

Description

Ball mill

Technical field

The utility model relates to suitable mine ore dressing, and a kind of ball mill that ball milling is given birth in the manufacture of cement, grog is used.

Background technology

Ball mill before the utility model, cylinder in its structure is the garden cylindricality, need certain gradient during installation, the feed inlet end height, discharge port end is low, because cylinder wall and liner plate are parallel with the axis of cylinder, it is insufficient to have occurred ball milling in the production, the phenomenon of running material from discharging opening is serious, forms disadvantages such as the partial circulating amount is big, has caused the waste of human and material resources; The idler frame is connected with drum shaft by bearing shell in addition, and rolling frictional resistance is big, and power consumption is also big.

Summary of the invention

Insufficient for the ball milling that solves existing ball mill existence, it is serious that discharging opening runs material, waste of manpower, material resources, and the big deficiency that waits of power consumption, the utility model will provide a kind of novel ball mill.The design of the utility model ball mill is, improve at existing ball mill, comprise the cylinder in the prior art, liner plate, drum shaft, layman's gear in its structure, and cylinder design has been taper type, on the idler frame, be provided with the bearing that is connected with drum shaft.Ball mill of the present utility model adopts the cylinder of taper type, make the axis of liner plate fixing on cylinder and the inner wall of rotary drum and cylinder not parallel, steel ball in the cylinder is evenly distributed when rotating like this, the bulk material is difficult for rolling to discharge port end, therefore ball milling is abundant, do not have the phenomenon of running material yet and take place, compare with the ball mill of same model in the prior art and saved human and material resources; Drum shaft changes into bearing and being connected, and has reduced rolling frictional resistance, has reduced power consumption.

Description of drawings

Accompanying drawing, be the structural representation of the utility model ball mill.

The specific embodiment

For the structure to the utility model ball mill has further understanding, accompanying drawings is as follows:

With reference to accompanying drawing, the structure of the utility model ball mill includes the cylinder 1 that is taper type among the figure, the liner plate 2 of the corrugated plate shape that on the inwall of cylinder 1, is connected and fixed by bolt, the bearing 3 that on the idler frame, is provided with, in two bearings 3, be respectively equipped be connected cylinder 1 two ends in a tubular form, with cylinder 1 in the drum shaft 4 and 5 that communicates, the mouth of pipe at the drum shaft 4 of the big end of cylinder 1 diameter is a charging aperture, the mouth of pipe at the drum shaft 5 of the little end of cylinder 1 diameter is a discharging opening, is provided with layman's gear 6 that engine drives on the outer wall of the little end of cylinder 1 diameter.

The utility model is transformed on existing ball mill, as long as cylinder is made into taper type, the bearing shell on the former idler frame is changed into bearing get final product, and former liner plate can utilize.

Claims (1)

1, a kind of ball mill, it includes cylinder (1), liner plate (2), drum shaft (4), (5), and layman's gear (6), it is characterized in that cylinder (1) is taper type, is provided with the bearing (3) that is connected with drum shaft (4), (5) on the idler frame.
