Example Embodiment

[0041] According to the invention Figure 4 to Figure 9 In the technical solution, the cylinder 4 is mounted on an elastic base composed of a spring 12 and a base 13, and the cylinder 4 is fixed. Two vibrating bodies 17 and an intermediate ring 18 are arranged in the cylinder. The intermediate ring is located between the two vibrating bodies. In the meantime, each vibrating body 17 is flexibly connected to the cylinder body through three cables 25 that form a mutual angle of 120°. The flexible shaft II21 connects the main shafts 31 of the two vibrating bodies 17 together, and ensures the eccentric blocks at the two proximal ends. In the same direction, the flexible shaft I15 connects the main shaft 31 of the left vibrating body with the output shaft of the transmission device 8 outside the cylinder. The transmission device 8 can decide whether to set a reduction gear according to the needs. The intermediate ring 18 has a tooth and groove structure at both ends Loosely link the ...

Abstract

The invention provides an inertial ball mill which is mainly applicable to operations of crushing and grinding massive or granular minerals. The inertial ball mill provided by the invention mainly comprises a moving system, wherein the moving system consists of a cylinder body, a lattice sieve plate, a classifying device, a plurality of vibrating bodies, middling rings and flexible shafts; the vibrating bodies, the middling rings and the flexible shafts are arranged in the cylinder body; the system is driven by a transmission device to perform high-speed rotational swinging movement to crush and grind materials. Through the inertial ball mill, the mill efficiency is greatly improved, and the energy consumption is reduced; the inertial ball mill is small in equipment size, light in weight, simple in structure and easy to maintain.

Description

[0001] background field [0002] The invention relates to an inertial ball mill, which is a device for grinding massive or granular minerals with different hardnesses into extremely fine particles, and is widely used in mineral processing, metallurgy, building materials, chemical industry, power generation and other industrial fields. Background technique [0003] In various grinding operations, ball mill is the most widely used equipment, because ball mill has the following advantages: (1) Strong adaptability to materials, continuous operation, large production capacity, and large-scale production Requirements; (2) The crushing ratio is large, up to 300 or more, and the product fineness is easy to adjust; (3) It can be adapted to dry and wet operations, and can also perform both grinding and drying operations at the same time; (4) Simple structure, Sturdy, reliable operation, easy maintenance and management. [0004] This ball mill is figure 1 As shown, it is a cylinder 4 a...
