Production method by connecting two cement grinding machine in series

Abstract

The invention provides a production method by connecting two cement grinding machine in series, which is implemented as follows: the two grinding machines in the same specification are connected in series for operation; positions of compartments of the grinding machines are changed; the grinding machine has two compartment generally, the spaces in the compartments are separated to 40 percent from the traditional 30 percent; two compartments of the front grinding machine are changed to grind by crushing raw materials through round steel balls from the traditional form; and the front compartment of the serially connected second grinding machine is changed to be round rectangular forging steel. The production method has the advantages that: by taking production of mechanical shaft kilns over 100,000 tons for instance, after the improvement, a powder concentrator can be saved, the output is improved, the total output per man-hour after traditional round rectangular forging steel is connected in parallel with the two grinding machines is improved to 24 tons from 15 tons, the electricity and coal consumption is reduced, the cost is saved, the output benefit of the whole year can be improved by 800,000 yuan, and the quality of cement is improved to over 320m2 per kilogram from the conventional 300m2 per kilogram; the raw materials are fully utilized, the three wastes are utilized, and the penetration of a mixed material is improved to over 25 from the conventional 20.

Description

Technical field: [0001] The technical field that the present invention relates to is about the production method of cement equipment, specifically a kind of production method of cement pulverizer two mills connected in series. Background technique: [0002] At present, the cement production mainly uses grinding equipment to kiln and crush the raw materials into fine powder. The mechanical shaft kiln with more than 100,000 tons is generally produced by one mill, and some two mills are connected in parallel. The mill size is 2.2 meters, 3.2 meters, 4 meters, usually according to the parallel operation of 2.2 meters, 3.2 meters mill, has the following characteristics: 1. The output is low when producing the table; 2. The investment is large, and the powder separator equipment needs to be increased; 3. The fine ratio of cement The surface is low and the workability is poor; 4. High energy consumption; 5. There are many production personnel and high labor intensity. Invention c...
