subject: Common Sense About The Dryer Machine [print this page] Copper concentrate dryer machine is the special machine used for drying common metal ores; it has the advantages of high drying efficiency, fast speed, and strong continuous operation capacity. Its drying effect is remarkable for the industry ores such as copper concentrate, hematite, etc.At present, the raw materials to refine copper in China mainly are towanite, chalcocite, bornite, malachite and etc. According to the technical conditions of smelting, the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide, that is, sulfide ore, which contains less than 10% copper oxideoxidized ore, which contains more than 30% copper oxide; mixed ore, which contains 10%~30% copper oxide.
Today we Hongxing Mining Machinery specially invited our professional experts who have many years experience in mining machinery industry to answer some hot questions on the core part of slime dryer impeller. First, what is impeller? The impeller can be said as the core parts of the dryer, which is equivalent to the human heart. Now let us discuss the impeller characteristics and its working principle in order to operate the machine correctly and avoid unnecessary risk operations for the masses of users.
The impeller is an important part of the dryer machine, and also is the most vulnerable part. Because the materials are distributed in the impeller, it is very easy to make the wear for the improper operation. So we should operate the machine with extra care to avoid the accidents and reduce unnecessary economic losses.
The impeller is installed on the top axis of the spindle assembly, and transferred the torque with tapered set and key bolt. In high-speed rotation, the materials are put into the center of impeller from the center feeding tube which is above the impeller. Hongxing dryer with cone device in the center of impeller can evenly distribute the materials to each channel. It also has special material wear block which can be replaced easily in each exit of channel. After the materials are in a certain speed, the impeller will threw them which will impact the lining layer in the crushing cavity.
First, when the displacement of rotary dryer cylinder appears, the cylinder belt will tilted walk on the side of supporting wheel, instead of parallel transport. This phenomenon is generally the result of wear between the wheel belt and supporting wheel, which damages the balance of cylinder installation angle (normally 5 degree). So we can adjust the angle of any set of supporting wheel according to the rotation direction of cylinder. In this way the cylinder can return to normal.
Second, use this method when the cylinder displacement is not big. When the cylinder moves down, we need to inwards parallel move the after supporting wheel, and appropriately increase the rear of cylinder. Improve less than 8 degrees till reset. We can improve the after supporting wheel to increase the contact areas between the supporting wheel and belt, and then move the cylinder back to reset. When the cylinder moves up, we can inwards parallel adjust the front supporting wheel.
Characteristics of the Industrial Dryer
First, an automatic control device is used. Time can be regulated simply through the control panel. You can automatically complete the entire drying process.
Second, the rotating drum is made of the high-quality stainless steel. The cylinder is beautiful smooth and durable without scratching fabric phenomenon.
Third, large access door design is convenient to freely open the door with 180 degrees. It is easier to draw the clothes.
Forth, the triangular rubber belt drive is used. The operation is smooth, safe and reliable with low noise.
