Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to pulverizing equipment, and particularly to pulverizing equipment for pulverizing and mixing two or more grains of material.

[Background of the invention]

When pulverizing and mixing a plurality of materials, as shown in FIG.
Material M1 from the hopper 3 to the crusher 5 by the feeder 4;
A mixture of M2 was being delivered. Moreover, materials M1 and M2
When the grindability of the materials differs, for example, when petroleum coke and petroleum pitch are ground and mixed, the degree of grinding of each material Ml and M2 becomes non-uniform.

Therefore, as shown in Fig. 2, a hopper 3, a feeder 4, and a crusher 5 are provided for each material M1 and M2, and
Mixing of rMl and M2vf was also performed. However, this crushing equipment requires the same number of crushers 5 as the types of materials, leading to an increase in equipment costs and operating costs.

[Purpose of the invention]

This invention was ingeniously designed to solve these conventional problems, and its purpose is to provide a pulverizing equipment that can pulverize and mix a plurality of materials to an appropriate degree using simple equipment. do.

[Summary of the invention]

In the crushing equipment according to the present invention, crushers with different degrees of crushing are arranged in the same path in order of the degree of crushing, a plurality of material supply paths are connected to this path, and a material supply path is selected for each material. It is something to do.

[Embodiments of the invention]

Next, an embodiment of the crushing equipment according to the present invention will be described based on the drawings.

In FIG. 3, the crushing equipment consists of a coarse crusher 7, an intermediate crusher 8, and a fine crusher 9 arranged in sequence in a pipe-like casing 6, and each crusher 7', 8.9 is one unit. It is coaxially driven by a motor 10. A first material supply path 11 is connected to the end of the casing 6 on the coarse crusher 7 side, and a raw material discharge path 12 is connected to the end on the fine crusher 9 side. The material Ml supplied from the material supply path 11 is sequentially pulverized by a coarse pulverizer 7, an intermediate pulverizer 8, and a fine pulverizer 9, and even if the material M1 is difficult to crush or has a large diameter, it is pulverized into a fine powder. be done.

A second material supply path 13 is connected to the casing 6 at a position between the coarse crusher 7 and the intermediate crusher 8, and the material M2 supplied from this material supply path 13 passes through the coarse crusher 7. Instead, it is pulverized only by the intermediate pulverizer 8 and the fine pulverizer 9. Therefore, when material M2 is a material that is easier to crush than material Ml or has a smaller diameter, material M2t - material M
It can be crushed to the same extent as 1.

By supplying the materials M1 and M2 from the material supply paths 11.13 at appropriate timings, both materials M1 and M2 can be mixed and crushed to an appropriate degree, respectively.

Each material supply path 11.13 is provided with an ore hopper 3 and a feeder 4, and the hoppers 3 are each supplied with materials Ml and M2 by a conveyor 1.2.

Note that this invention is not limited to this example,
It is also possible to arrange more pulverizers with different degrees of pulverization, and more material supply paths may be provided.

[Effects of the invention]

As mentioned above, the crushing equipment according to Jin's invention arranges crushers with different degrees of crushing in the same path in order of the degree of crushing, connects a plurality of material supply paths to this path, and connects each material to a Since the material supply path is selected, there is an excellent effect that a plurality of materials can be pulverized and mixed to an appropriate degree using simple equipment.
