Inertial ball mill

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...

Problems solved by technology

[0005] The main disadvantages of this kind of ball mill are: (1) The working efficiency is very low, usually the volume utilization rate is less than 50%, the working speed is only 15-30r / min, and no further increase is allowed, the effective utilization rate of electric energy is only about 4%, and the remaining large Part of it is wasted as heat, and the power consumption of the grinding operation is about 2 / 3 of the total power consumption; (2) the noise is loud during work; (3) the body is huge and heavy, and the larger one is more than 1,000 tons

Although this type of equipment is light in weight and high in action frequency, it has small amplitude, small action force, small range of feeding particle size, and low output, so it is difficult to meet the needs of large-scale production.
