Quantitative feeding cement raw material roller press system

Abstract

The invention relates to a quantitative feeding cement raw material roller press system. The quantitative feeding cement raw material roller press system is used for rolling cement raw materials, andthe quantitative feeding cement raw material roller press system comprises a feeding conveying device for conveying the cement raw materials, a feeding device connected with the feeding conveying device and used for receiving the cement raw materials conveyed by the feeding conveying device and uniformly stirring the cement raw materials, a material locking electromagnetic valve arranged at the discharging end of the feeding device and used for controlling the discharge of the discharging end of the feeding device and a roller press, wherein the roller press comprises a machine body, a fixed extrusion roller and a floating extrusion roller, the fixed extrusion roller and the floating extrusion roller are correspondingly arranged in the machine body, a quantitative feeding accommodating binis formed between the fixed extrusion roller, the floating extrusion roller and the machine body, and the quantitative feeding accommodating bin is connected with the feeding device. The quantitativefeeding cement raw material roller press system uses a control device to perform linkage control over the working states of the roller press, the feeding conveying device and the feeding device, andquantitative feeding and automatic control of the quantitative feeding cement raw material roller press system are realized.

Description

technical field [0001] The invention relates to a roller press system, in particular to a cement raw meal roller press system for quantitative cutting. Background technique [0002] The roller press is designed according to the principle of material bed grinding, and its main features are: high pressure, full speed, full material, material bed crushing. The roller press consists of two extrusion rollers that rotate synchronously in opposite directions, one is a fixed roller and the other is a movable roller. [0003] The material is fed from the top of the two rollers, and is continuously brought into the gap between the rollers by the extrusion roller, and after being subjected to a high pressure of 100-150MPa, it becomes a dense cake and is discharged from the bottom of the machine. The discharged material cake contains a certain proportion of fine-grained finished products. In the interior of the non-finished particles, a large number of cracks are generated, which impr...

Problems solved by technology

[0007] 2. The bearing temperature is too high or the temperature difference is large

[0008] 3. The deviation of the gap between the two rolls is unstable. Before use, it is necessary to check the deviation of the gap between the two rolls and whether the pressure of the hydraulic system on both sides is balanced. Is it the same

[0009] 4. The roller surface is easily damaged. When rolling the cement raw meal, if there are metal impurities in the cement raw meal, the roller surface is prone to cracks or pits on the roller surface or the hard wear-resistant layer on the roller surface peels off

When the hammer head wears for a period of time, especially in the later stage, the particle size of the small crushed stones discharged from the crusher seriously exceeds the standard, with an average particle size of 60mm and a maximum diameter of more than 120mm, which will cause the vibration of the roller press to increase and the system to trip and stop
