The Indispensable Production Details of High Frequency Screen

High frequency screen is often used for the grading of fine particles in the grinding process of ore dressing plant, in the conditions of appropriate feed concentration, feed particle size (-200 mesh size), screen size and particle size of less than 30 percentage points, its screening efficiency is more than 70%. Because the screening efficiency is high, it can greatly reduce the circulating load and qualified particle content, so as to improve its processing capability. With the continuous progress of domestic beneficiation technology, various kinds of mineral processing equipment blossom everywhere in the industry. Now the kinds of mineral processing equipment is complex, high frequency screen is one of the best. Hongxing engineering and technical personnel will share with you the operation tips of high frequency screen through practical experience for many years.

First of all, in operation of the high frequency screen, when the cloth bucket into the sieve plate of the pulp flow shot is far, it should adjust the screen position or angle frame, so as not to affect the efficiency of classification. When the screen has been used for one month, the screen piece is taken off, turn the 180 degree to enhance the screen 'cutting' effect, so as to improve the classification efficiency.

Secondly, in operation process of high frequency screen, it can be adjusted according to the ore properties and operational requirements. The adjustment of the excitation current (amplitude) can make the screen at maximum efficiency conditions, which can be used as excitation current condition test. Notice the ammeter pointer, which cannot exceed the amount of value, the screen machine is running every half a month or so, which should be current adjustment in the past, so that the sieve back objects can be struck out.

Thirdly, in operation of the high frequency screen, you can also check the various parts of the bolts whether they are loose at any time, and whether the screen frame has chute collision. The electromagnetic vibration exciter and control box can prevent drench water in case of short circuit. The plywood exciter cover can prevent falling into the water of the slurry, which will cause a short circuit and clogging the air gap.

Finally, because the screen high classification efficiency and good performance of sieve dehydration, which should be paid particular attention. If the concentration is high, it will make the screen pulp liquidity difference in amount of chute. When the high frequency screen is in normal operation, you should always observe the screen and control the concentration about 40%, so as to improve the classification efficiency.
