Fine Mill Equipment Tube Grinding Mill For Mining Grinding Cement

Fine Mill Equipment Tube Grinding Mill Ore Grinding Mill For Mining

1. Introduction of tube grinding mill of ore grinding mill
The tube mill is designed in the advantages and disadvantages of the open-flow grinding system. It has made a significant improvement on the traditional ball mill. In addition to all the advantages of open-flow grinding, compared with the ball mill of the same specification, the mill output has been greatly improved, and the powder is fine, the specific surface area is increased, to achieve high yield, high fine. It provides a new type of grinding equipment for producing high grade cement.
The tube mill of Luo mine adjusts the material level of each bin, increases the ventilation volume and improves the conditions inside the mill by its unique combination of bin separator and discharge separator. At the same time, the new liner is used to adjust the speed of the mill, optimize the gear design and lubrication parameters of the bearing bush, increase the stability and service life of the mill, and improve the grinding efficiency.
Compared with the ball mill of the same specification, the output of the tube mill is increased by 20% and the power consumption per unit product is decreased by 10-12% under the condition that other parameters are unchanged. The specific surface area of cement can be up to 320m2/kg in open-flow grinding.

2. The technical characteristics of the mill developed and designed are as follows:
(1) The transmission forms of drum mill are edge leaflet, center transmission, multi-point meshing edge transmission and other transmission types; Drive form of induction motor + reducer + pinion + big gear and synchronous motor + air clutch + pinion + big gear;
(2) Generally, the support mode of two-terminal static and dynamic pressure bearing is adopted, and the fully enclosed self-aligning 1200 line contact 'rocker type' bearing is adopted. The static and dynamic pressure support mode of single sliding shoe, double sliding shoe or full static pressure support can also be adopted.
(3) Large open gear adopts American AGMA standard design, equipped with a reliable sealing gear cover, equipped with glycerin automatic spray lubrication device;
(4) The cylinder is a key part of the mill, and the finite element analysis is carried out on it by computer to ensure its reliability;
(5) Large and medium mills are equipped with slow driving device;
(6) Large and medium mills are equipped with high and low pressure lubrication stations;
(7) Control and protection system adopts PLC control.

3. Technical characteristics of tube grinding mill of ore grinding mill
(1) Transmission form: center transmission and edge transmission (including multi-point meshing type of edge transmission). Large and medium mill with slow drive.
(2) Supporting mode of the mill: main bearing type, double sliding shoe type and mixed type (one end of the main bearing, with one end of the sliding shoe). Bearing and bracket are processed by CNC machine tool. The three supports are equipped with high and low pressure lubrication devices.
(3) Rotary part: the cylinder body adopts automatic welding, the weld seam is 100% ultrasonic inspection, the whole annealing after welding of the cylinder body, fully eliminate the welding stress; The cylinder body adopts a large special machine tool to install the card processing, which effectively ensures the coaxiality of the slip ring (main bearing) at both ends, so that the equipment can run smoothly.
(4) Feeding and discharging device: with hollow shaft or drive pipe and other static and dynamic joint with a special seal, to ensure no oil leakage, no ash leakage.
(5) System control: the whole mill system is controlled by PLC, which can realize temperature inspection and vibration detection of all bearings and lubricating oil of the mill supporting device and reducer, and can realize computer joint control with the central control room.
