Tube Mill Ore Grinding Mill Asynchronous Motor PLC Control AGMA Standard

Ore Grinding Mill Tube Mill

1. Technical characteristics of the mill(ore grinding mill)
(1) The transmission forms used by the drum mill include edge leaflet, center drive, multi-point meshing edge drive, etc.; the drive forms include asynchronous motor + reducer + pinion + large gear and synchronous motor + air clutch + pinion + large gear;
(2) Generally, the support method of static and dynamic pressure bearings at both ends is adopted, and a fully enclosed self-aligning 1200 line contact 'rocker type' bearing is used. Full static pressure support;
(3) The large open gear is designed according to the American AGMA standard, equipped with a sealed and reliable gear cover, and equipped with a glycerin automatic spray lubricating device;
(4) The cylinder is the key part of the mill, and a computer is used to carry out finite element analysis on it to ensure the reliability of its use;
(5) The large and medium-sized mills are equipped with slow drive devices;
(6) Large and medium-sized mills are equipped with high and low pressure lubrication stations;
(7) The control and protection system adopts PLC control.
 
2. Basic introduction of tube mill(ore grinding mill)
The tube mill is designed to take advantage of the advantages and disadvantages of the open-flow grinding system, and has made significant improvements to the traditional ball mill. The output of the machine has been greatly improved, and the powder fineness and specific surface area have increased, realizing high yield and high fineness, and providing a new type of grinding equipment for the production of high-grade cement.​​
The Luokuang tube mill adjusts the material level of each bin with its unique combined partition board and discharge grate board, increases the ventilation volume, and improves the conditions inside the mill; at the same time, it adopts a new type of lining board, adjusts the speed of the mill, and optimizes the The gear design and the lubrication parameters of the bearing bush are improved, the running stability and service life of the mill are increased, and the grinding efficiency is improved.
Under the condition that other parameters remain unchanged, the output per unit is increased by 20%, and the power consumption per unit product is decreased by 10-12%; in open-flow grinding, the specific surface area of ​​cement can reach 320m2/kg.
 
3. Technical characteristics of Luokuang tube mill(ore grinding mill)
(1) Transmission form: center transmission and edge transmission (including edge transmission in the form of multi-point meshing). Large and medium-sized mills are equipped with slow drives.
(2) The support mode of the mill: main bearing type, double sliding shoe type and hybrid type (one main bearing at one end and one end sliding shoe). Bearing bushes and supporting pads are processed by CNC machine tools. All three supports are equipped with high and low pressure lubricating devices.
(3) Rotary part: the cylinder body is automatically welded, the weld seam is 100% ultrasonic inspection, the cylinder body is annealed as a whole after welding, and the welding stress is fully eliminated; the cylinder body is processed by a large special machine at one time, which effectively ensures the slip rings at both ends. (main bearing) coaxiality, so that the equipment can run smoothly.
(4) Feeding and discharging device: There are special seals with the dynamic and static joints such as the hollow shaft or the transmission connection to ensure that it does not leak oil or ash.
(5) System control: The entire mill system is controlled by PLC, which can realize temperature inspection and vibration detection of the mill support device and all bearings and lubricating oil of the reducer, and can realize computer joint control with the central control room.
