Problems solved by technology

[0003] However, the dust collector often has incomplete dust removal, and there will still be a small amount of dust discharged into the air with the air flow. The dust collection effect is not good, which will affect the environment and the health of workers.

Embodiment 1

[0038] A production process for making stable cement raw meal, comprising the following steps:

[0039] a. Crushing the raw materials through the crusher;

[0040] b. Collect the dust generated by the crusher through the dust collector;

[0041] c. Add lime with 2% cement raw meal content and 5% pure cement with cement raw meal raw material obtained by pulverizing with a crusher;

[0042] d. Add water and mix in a pre-humidifier;

[0043] e. Feed the water-added raw materials into the disc-type ball forming machine to make raw meal balls. The ball forming time is 100 seconds, and the particle size of the raw meal balls is 3mm;

[0044] f. Naturally preserve the raw material balls at room temperature for more than two days.

[0045] Such as Figure 1-7 As shown, the dust collector includes a frame 1, a main cylinder body 11, an air outlet pipe 12, an air inlet pipe 13, a dust outlet 14 and a dust collecting device. The main cylinder body 11 is welded on the frame 1, and the...

Embodiment 2

[0056] A production process for making stable cement raw meal, comprising the following steps:

[0057] a. Crushing the raw materials through the crusher;

Abstract

The invention discloses a production process for preparing a stable cement raw material. The production process comprises the following steps: a, crushing raw materials by using a crusher; b, collecting dust generated by the crusher through a dust collector; c, adding lime accounting for 2-4% of the amount of the cement raw material and pure cement accounting for 5-10% of the amount of the cementraw material into the raw materials crushed by the crusher; d, adding water and mixing in a pre-wetting machine; e, feeding the raw materials added with water into a disc type pelletizer to prepare raw material pellets; and f, naturally curing the raw material pellets at room temperature for more than two days.

Description

technical field [0001] The invention belongs to the technical field of cement processing, and in particular relates to a production process for making stable cement raw meal. Background technique [0002] In the process of cement processing and production, there are many dust particles in the air, which seriously affects the lung health of the staff. The dust collector can filter the air passing through it; and the dust collector often adopts a cyclone dust collector. The cyclone dust collector is a kind of gas dust removal device. Its dust removal principle is to make the dust-laden air flow rotate under the driving action of the fan in the previous process, and use centrifugal force to separate the dust particles from the air flow and collect them on the wall, and then Dust particles fall into the ash discharge hopper by gravity. [0003] However, the dust collector often has incomplete dust removal, and there will still be a small amount of dust discharged into the air w...
