Embodiment 1

[0031] figure 1 Shown is a schematic structural diagram of the machine-made sand production system of the present invention, including a hopper 1, and a ball mill 2 for grinding materials, and a connecting belt for transferring the materials in the hopper 1 to the ball mill 2, which is used for screening the materials obtained by the ball mill 2. The powder separator 4 is used to transfer the output of the ball mill 2 to the hoist 3 of the high-efficiency powder separator 4, and is used to receive the machine-made sand warehouse 6 for receiving the discharge of the high-efficiency powder separator 4; the air outlet of the high-efficiency powder separator 4 is connected to a Dust collector 5, the air outlet of dust collector 5 is connected with dust collection fan 8; the discharge port of dust collector 5 is connected with dust collection fine powder storehouse 7; connected to the air inlet. The ball mill 2 is a horizontal ball mill. The cylinder of the horizontal ball mill us...

Embodiment 2

[0046] The machine-made sand production system of this embodiment is the same as that of Embodiment 1. The ball mill 2 is a horizontal ball mill. The cylinder of the horizontal ball mill used in this embodiment has a diameter of 2.2 m and a length of 6.5 m. The supplier of the high-efficiency powder separator 4 For Shangrao Machinery Factory, the model is HES-30.

[0047] The operation process of the machine-made sand production system of the present invention is as follows: the loader puts the stones with a particle size ≤ 5mm obtained by upstream pretreatment into the hopper 1, and the materials in the hopper 1 are sent to the ball mill 2 through the conveyor belt, and the ball mill 2 is a horizontal ball mill. , the diameter of the cylinder is 2.2m, and the length is 6.5m. The steel ball inside the ball mill 2 performs ball milling on the stone material. The material fineness modulus at the outlet of the ball mill is 2.2-2.6, and the material enters through the screen at the...

Embodiment 3

[0053] The machine-made sand production system of this embodiment is the same as that of Embodiment 1. The ball mill 2 is a horizontal ball mill. The cylinder of the horizontal ball mill used in this embodiment has a diameter of 1.8 m and a length of 13 m. The supplier of the high-efficiency powder separator 4 is Shangrao Machinery Factory, the model is HES-30.

[0054] The operation process of the machine-made sand production system of the present invention is as follows: the loader puts the stones with a particle size ≤ 5mm obtained by upstream pretreatment into the hopper 1, and the materials in the hopper 1 are sent to the ball mill 2 through the conveyor belt, and the ball mill 2 is a horizontal ball mill. , with a diameter of 1.8m and a length of 13m. The steel balls inside the ball mill 2 mill the crushed stones. The material fineness modulus at the outlet of the ball mill is 2.2-2.6. The machine 3 and the elevator 3 send the material into the high-efficiency powder sep...

Abstract

The invention provides a machine-made sand production system, and a production method and application thereof. The machine-made sand production system comprises a hopper, and also comprises a ball mill for milling materials, a connection belt for conveying a material in the hoper to the ball mill, an efficient power separator for screening the material obtained from the ball mill, an elevator for transmitting the material discharged from the ball mill to the efficient powder separator, and a machine-made sand bin for receiving the material discharged from the efficient powder separator. The production method for the machine-made sand comprises performing ball milling crushing on a stone material and performing efficient winnowing on the material. The beneficial effects comprise that the made machine-made sand is controllable in fineness modulus, that is, the purpose of adjusting the discharge fineness of the machine-made sand by adjusting the ratio of large and small steel balls in the ball mill and the feed amount of crushed stone particles, and also machine-made sand and limestone powder with ideal grain gradation can be obtained by adjusting the material-spreading-plate rotation speed of the efficient powder separator, and the problems that machine-made sand is uncontrollable in grain gradation and dust content in the prior art are effectively solved.

Description

technical field [0001] The invention belongs to the field of machine-made sand production, and in particular relates to a machine-made sand production system and its production method and application. Background technique [0002] Sand plays an important role in filling the voids of coarse aggregate in concrete and improving the workability of concrete. Commonly used sand includes natural river sand, artificial gravel machine-made sand, artificial pebble machine-made sand, etc. The traditional river sand for production is excavated from various river channels. Due to the excessive exploitation of a large number of river channels, the speed of flood discharge in the river channel is affected, and the ecological environment of the area is damaged. Serious damage to Hanoi's water quality and other hazards. Therefore, the state clearly stipulates that except for a small number of rivers where river sand is allowed to be re-mined, the rest are not allowed to be mined. Therefor...
