Problems solved by technology

The production cost of using coal gangue to produce coal gangue bricks is lower than that of ordinary clay bricks. Using coal gangue to make bricks not only saves land, but also consumes mine waste. It is a low-carbon building material that is conducive to environmental protection; coal gangue bricks Coal gangue needs to be crushed during production and processing. The traditional pulverizer is only composed of a crushing bin and a beater. The inertia of the beater is small. When encountering a hard stone or a stone stuck in the gap, the pulverizer will stop suddenly.
[0003] In this way, there are problems such as unstable equipment operation, large mechanical wear, and low equipment life.

Embodiment 1

[0021] Such as figure 1 As shown, a pulverizer for crushing coal gangue, the pulverizer is mainly composed of a casing, a crushing bin and a counterweight system; the counterweight system is mainly composed of a lower casing 2, a drum 9, a connecting rod 11 and a counterweight Hammer 14 is formed, and one end of connecting rod 11 is connected with drum 9 through fixed rotating shaft, and the other end of connecting rod 11 is connected with counterweight hammer 14 through pin 13, and the middle part of connecting rod 11 is connected with lower casing 2 through fixed shaft 12.

[0022] When the crusher is working, when it encounters a hard stone, it will cause a greater impact on the equipment and bring a greater acceleration. When the stone cannot be crushed, the equipment will cause an emergency stop, which will cause huge damage to the equipment. destroy. When the drum 9 rotates, it drives the connecting rod 11 to move up and down, and the connecting rod reciprocates left an...

Embodiment 2

[0024] On the basis of Example 1, this embodiment discloses a preferred structure of a pulverizer for pulverizing coal gangue, such as figure 1 As shown, the crushing bin is mainly composed of moving equipment and fixed equipment; the fixed equipment is mainly composed of a material guide channel 5, a connecting cross bar 8, a screen 16, a crushing bin lower shell 17, and a crushing bin upper cover 18. The lower shell 17 of the bin is connected with the upper cover 18 of the crushing bin, the material guide channel 5 is connected with the upper cover 18 of the crushing bin, the material guide channel 5 is provided with a feed port baffle 6; the inner wall of the upper cover 18 of the crushing bin is provided with an upper baffle 4, The inner wall of the lower shell 17 of the crushing bin is provided with a lower baffle plate 15, and the two ends of the connecting bar 8 are respectively connected to both sides of the inner wall of the upper cover 18 of the crushing bin, and the ...

Embodiment 3

[0027] On the basis of Embodiment 2, this embodiment discloses a preferred structure of a pulverizer for pulverizing coal gangue, such as figure 1 As shown, the movement equipment of the crushing bin is mainly composed of a crushing hammer 7, a drum 9 and a rotating shaft 10, the drum 9 is sleeved on the rotating shaft 10, and the rotating shaft 10 is connected to the lower shell 17 of the crushing bin through a bearing; Roller 9 is connected. The crushing hammer has a large mass and high crushing efficiency.

[0028] The shell is mainly composed of a base 1, a lower shell 2 and an upper shell 3, the base 1 is connected to the lower shell 2, the upper shell 3 is connected to the lower shell 2, and the cavity formed by the base 1, the lower shell 2 and the upper shell 3 will be crushed Warehouse package included. The casing wraps the crushing chamber, which not only reduces the processing noise of the equipment, but also improves the structural stability of the equipment. Ot...

Abstract

The invention discloses a pulverizer used for pulverizing coal gangue. The pulverizer is mainly composed of a base (1), a lower shell (2), an upper shell (3), upper baffles (4), material guiding channels (5), a material port baffle (6), a pulverizing hammer (7), a connecting transverse rod (8), a roller (9), a rotating shaft (10), a connecting rod (11), a fixing shaft (12), a pin (13), a balance weight hammer (14), lower baffles (15), a screen (16), a pulverizing bin lower cover (17) and a pulverizing bin upper cover (18). By means of the arrangement of the balance weight system, the stability of working can be improved; mechanical abrasion is reduced; the service life of the equipment is prolonged; the economic benefit is improved; the machining noise of the equipment can be reduced; and the structural stability of the equipment can be improved.

Description

technical field [0001] The invention relates to the field of gangue bricks and the field of machinery, in particular to a pulverizer for pulverizing coal gangue. Background technique [0002] 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. The main component of gangue bricks is gangue. Coal gangue is solid waste discharged during the coal mining process and coal washing process. Its main components are Al2O3 and SiO2, and it also contains varying amounts of Fe2O3, MgO, Na2O, K2O, P2O5, SO3 and trace rare elements. The production cost of using coal gangue to produce coal gangue bricks is lower than tha...
