Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the aggregate of the existing vertical crusher after primary crushing will have a relatively large impact force on the inner wall of the crusher due to its relatively large volume and weight. The inner wall is damaged, and the traditional vertical crusher cannot obtain aggregates of two particle sizes at the same time after crushing the aggregate. The present invention provides a wear-resistant vertical crusher.

Embodiment 1

[0019] like figure 1 As shown, a wear-resistant vertical crusher includes a crushing cavity and a crushing mechanism, the top of the crushing cavity is provided with an aggregate inlet 1 and a cavity cover 2, and the crushing mechanism includes a motor 3 and the crushing mechanism. The rotating shaft connected to the motor 3, the rotating shaft is provided with a crushing rotor, the crushing rotor includes a crushing blade 4, a connecting rod 5 for installing the crushing blade 4, the motor 3 is connected to the rotating shaft through a gear; the crushing cavity includes a main The crushing chamber 6, the lower part of the main crushing chamber 6 is divided into the first crushing chamber 7, the second crushing chamber 8 and the third crushing chamber 9, the top of the second crushing chamber 8 and the main crushing chamber 6 A first solenoid valve 10 is provided, a second solenoid valve 11 is provided between the top of the third crushing chamber 9 and the crushing chamber; a...

Embodiment 2

[0022] On the basis of Embodiment 1, a ventilation net 21 is arranged under the lid, and the material of the ventilation net 21 is W18Cr4V. During the crushing process, the inner wall of the crusher will generate heat. If the inside of the crusher is completely closed, the temperature inside will be very high, and the equipment will be ignored. Heat dissipation is carried out inside the machine. In specific implementation, specific ventilation equipment, cooling equipment, etc. can be prevented outside the ventilation net 21.

Embodiment 3

[0024] On the basis of Example 1 or Example 2, the bottom of the first crushing chamber 7 is provided with a first material outlet, the bottom or side of the second crushing chamber 8 is provided with a second material outlet, and the third The bottom of the crushing chamber 9 is provided with a third material outlet.

Abstract

The invention discloses a wear-resistant vertical crusher, which relates to the field of aggregate fine crushing, and includes a crushing cavity and a crushing mechanism. The top of the crushing cavity is provided with an aggregate inlet and a cavity cover. The crushing mechanism includes a motor, A crushing rotor is provided on the rotating shaft connected to the rotating shaft, the crushing rotor includes a crushing blade, a connecting rod for installing the crushing blade, the motor is connected to the rotating shaft through a gear; the crushing chamber includes a main crushing chamber, The lower part of the main crushing chamber is divided into the first crushing chamber, the second crushing chamber and the third crushing chamber, a first electromagnetic valve is set between the top of the second crushing chamber and the main crushing chamber, and the third crushing chamber Due to the relatively large volume and weight of the aggregate after the primary crushing of the existing vertical crusher, it will generate a large impact force on the inner wall of the crusher, and this impact force will cause damage to the inner wall, and The traditional vertical crusher cannot obtain aggregates of two particle sizes at the same time after crushing aggregates.

Description

technical field [0001] The invention relates to the field of aggregate fine crushing, in particular to a wear-resistant vertical crusher. Background technique [0002] Vertical impact crusher is called vertical crusher for short. It is suitable for crushing and shaping of soft or medium-hard and extremely hard materials. Fine crushing and coarse grinding of machine-made construction sand, construction aggregate, artificial sand, and various metallurgical slags, especially for high-hardness, extra-hardness, and wear-resistant materials such as silicon carbide, corundum, sintered bauxite, and American sand. The output efficiency of this type of crusher is higher. In the field of engineering, it is an ideal production equipment for machine-made sand, cushion material, asphalt concrete and cement concrete aggregate. In the field of mining, sand making machines are widely used in the front-end process of grinding, which can produce a large amount of fine ore and reduce the high...
