Features of fine powder grinding machine
1. Low operation cost of fine powder grinding machine
it can high efficiently crush the materials by grinding rollers and material bed. So the power consumption system is 40-50% less than the ball mills system. And its energy-saving effect will be more prominent with the increase of the materials'humidity.
2. Low installation cost of fine powder grinding machine
(a) compared with the ball mill, it has a simple crafts process and covers an small construction area, with the covering area less than 50% and construction cost less than 70%.(b) This machine merges the crushing, drying, grinding, and classifying into a single whole. With a simple structure and compact layouts, it is suitable for the outdoor design, which ensures a low construction cost.
3. Reliable Function of fine powder grinding machine
(a) Equipped with the automatic controlling equipment, it has realized the remote control, which makes a convenient operation.
(b) It has the equipment which can prevent the direct touch between the roller sleeve and grinding plate, which can avoid the crushing intense shaking.
4. Easy to Repair of fine powder grinding machine
the roller sleeve and plate are easy to change in a short time by fixing the oil tank and turning around the flexible arms.
5. Environment-Friendly of fine powder grinding machine
Environment-friendly, energy-saving; slight vibration, low noise and dust; clean working condition.
6. Reliable Quality of fine powder grinding machine
With the splate products quality and even particle size, it makes the materials have a short stay in the mill. This is convenient to test and control the products size and the chemistry ingredients the products size: 352-6000meshes.
Work Principle of fine powder grinding machine
The new type vertical superfine grinder consists of screw feeder, main unit, blower, separator, cyclone powder collector, bag powder collector, piping system, and PLC electric control system with frequency conversion and high configuration. The main unit is composed of upper and lower body, grinding roller, grinding table, hydraulic loading and hoisting system, air distributing channel, main motor, speed reducer, etc. When working, the raw materials is fed into the main unit evenly and continuously by the screw feeder on the side of the above of the main body. Under the action of the centrifugal force caused by the rapidly rotating grinding table, the materials are throw to the inside wall of the grinding table and brought to the zone of action of grinding rollers and the grinding table. Through the hydraulic loading to the grinding rollers, and the differential transformer of the grinding rollers and the grinding table, the materials are pulverized after being sheared and crimped strongly in the zone of action. The high pressure and big flow air currents caused by the blower will be combined with the crushed powder through the closed cycle air supply system, to form high concentration ones, and then go to the separator above the main unit to classify the powder. The unqualified fine particles will fall back to the grinding table and be grinded once again. The qualified micropowder will go through the separator with the air currents and then go into the cyclone powder collector. In the powder collector, The micropowder separated with the air will be out from the discharge port to be the finished product. In the air cycle process, the little spare air together with the light impurity in the finished products will be collected by the branch dust collector to be processed as lowgrade products. Then it forms a scientific and advanced process.
