Description

A pulverizer capable of both coarse crushing and fine crushing

technical field

The utility model relates to the field of mechanical equipment, in particular to a pulverizer capable of coarse crushing and fine crushing.

Background technique

A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of pulverizing in the form of high-speed impact. Using wind energy to form powder at one time, canceling the traditional screening procedure. It is mainly used in mining, building materials and other industries. Generally, according to the degree of crushing, it can be divided into crushers, pulverizers, and ultrafine pulverizers. Existing pulverizers are too single to be capable of both coarse crushing and fine crushing, and generally the blades of fine crushing grinders are more fragile and more expensive than those of coarse crushing.

Utility model content

The problem to be solved by the utility model is to provide a pulverizer capable of coarse crushing and fine crushing, which can not only coarsely crush but also finely crush, and can effectively protect the fine crushing blades during fine crushing.

The utility model solves the technical problem and adopts the following technical solutions:

A pulverizer capable of coarse crushing and fine crushing, comprising a shell and a frame below the shell, the top of the shell is provided with a feed port, the bottom of the shell is provided with a discharge port, and the shell is provided with The coarse crushing chamber and the fine crushing chamber under the coarse crushing chamber, a partition is provided between the coarse crushing chamber and the fine crushing chamber, one end of the partition protrudes from the housing, a first rotating shaft is arranged in the coarse crushing chamber, and the A second rotating shaft is arranged in the fine crushing chamber, and a first motor and a second motor are arranged on one side of the housing. One end of the first rotating shaft protrudes from the housing and is connected with the first motor through a universal joint. The second rotating shaft One end protrudes from the casing and is connected to the second motor through a universal joint. The first rotating shaft is provided with coarse crushing blades, and the second rotating shaft is provided with fine crushing blades.

Preferably, a handle is provided at the end of the partition protruding from the housing.

The beneficial effects of the utility model are: on the basis of the prior art, the utility model provides a coarse crushing cavity and a fine crushing cavity in the shell of the pulverizer, and a partition is used to separate the coarse crushing cavity and the fine crushing cavity. Coarse crushing in the coarse crushing chamber, and fine crushing in the coarse crushing chamber, and then the partition is opened to finely crush in the fine crushing chamber. In this way, both coarse crushing and fine crushing can be performed, and the fine crushing blade can be effectively protected during fine crushing.

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

As shown in Figure 1, a pulverizer capable of coarse crushing and fine crushing includes a housing 1 and a frame 2 below the housing 1, the top of the housing 1 is provided with a feed port 11, and the bottom of the housing is A discharge port 12 is provided, and the housing 1 is provided with a coarse crushing chamber 13 and a fine crushing chamber 14 under the coarse crushing chamber 13, and a partition 15 is arranged between the coarse crushing chamber 13 and the fine crushing chamber 14, and the partition One end of the plate 15 protrudes from the housing 1, the coarse crushing chamber 13 is provided with a first rotating shaft 16, the fine crushing chamber 14 is provided with a second rotating shaft 17, and one side of the housing 1 is provided with a first motor 18 and a second motor. Motor 19, one end of the first rotating shaft 16 protrudes from the housing 1 and is connected to the first motor 18 through a universal joint, and one end of the second rotating shaft 17 protrudes from the housing 1 and is connected to the second motor 19 through a universal joint Connected, the first rotating shaft 16 is provided with a coarse crushing blade 20, and the second rotating shaft is provided with a fine crushing blade 21.

In a specific design, a handle 22 is provided at the end of the partition 15 protruding from the housing 1 .

The utility model provides a pulverizer capable of coarse crushing and fine crushing. The utility model aims at the deficiencies in the prior art, and offers a coarse crushing chamber 13 and a fine crushing chamber 14 in the pulverizer housing 1, and a dividing plate 15 is used to separate the coarse crushing chamber 13 and the fine crushing chamber 14. When coarse crushing is required, materials are added, and the first motor 18 is turned on for coarse crushing. When fine crushing is required, first crush in the coarse crushing chamber 13, then pull the partition 15 through the handle 22, close the partition 15 after all the materials fall into the fine crushing chamber 14, and turn on the second motor 19 for fine crushing. In this way, both coarse crushing and fine crushing can be performed, and the fine crushing blade 21 can also be effectively protected during fine crushing.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. Any equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
