Raw Gold Processing Milling Machine features

1. Unique design. In the grinding chamber of the Raw Gold Processing Milling Machine, a 1500kg & mdash; 2000kg pressurizing device is designed on the upper part of the plum blossom frame. Under the same power, the output is increased by 10-30%, and the grinding pressure of the grinding device is increased by 800-1500kgf. The degree can be as fine as 1000 mesh.

2. The material has strong applicability and can be used for various materials with Mohs hardness below 9.3.

3. The dust removal effect fully meets the national standards.

4. The Raw Gold Processing Milling Machine grinding roller device adopts high quality and efficient processing technology, and the overlapping multi-stage sealing ensures a good sealing effect.

5, the grinding roller, grinding ring replacement cycle is long, eliminating the shortcomings of the replacement cycle of the wearing parts of the centrifugal pulverizer.

6. The Raw Gold Processing Milling Machine grinding device adopts overlapping multi-stage sealing and has good sealing performance.

Raw Gold Processing Milling Machine range

The Raw Gold Processing Milling Machine is mainly suitable for processing non-flammable and explosive mineral products with Mohs hardness below 9.3 and humidity below 6%. It is used in metallurgy, building materials, chemical industry, mining, highway construction, water conservancy and hydropower industries. It has a wide range of applications and is ideal for processing quartz, feldspar, calcite, limestone, talc, ceramic, marble, granite, dolomite, bauxite, iron ore, barite, bentonite, coal gangue, coal and other materials. The finished product fineness can be adjusted from 0.613 mm to 0.033 mm.

Raw Gold Processing Milling Machine working principle

In the main body of the Raw Gold Processing Milling Machine, the grinding roller assembly is suspended on the grinding roller hanger through the cross-supporting shaft, the grinding roller hanger is fixedly connected with the main shaft and the blade holder, and the pressure spring is pressed on the outer surface of the cantilever of the grinding roller bearing chamber. Above, the cross roller shaft is used as a fulcrum to force the grinding roller to be tightly pressed on the inner circular surface of the grinding ring. When the motor drives the main shaft to rotate through the transmission device, the blade mounted on the blade holder rotates synchronously with the grinding roller, and the grinding roller is The inner circle of the grinding ring rotates around its own axis while rolling. The motor drives the analyzer to rotate through the transmission. The higher the impeller speed, the finer the sorted powder. In order to ensure that the mill works under negative pressure, the increased air flow is discharged into the bag filter through the residual air pipe between the fan and the main engine, and is purified and discharged into the atmosphere.

The air-selected airflow of the Raw Gold Processing Milling Machine is circulated and flowed in the fan-grinding-cyclone-fan, so it has less dust than the high-speed centrifugal pulverizer, and the operation workshop is clean and the environment is free from pollution.

Two test methods for Raw Gold Processing Milling Machines:

After the installation of the Raw Gold Processing Milling Machine, the commissioning work is necessary. The test run includes no-load test and on-load test. Only when the test vehicle meets the requirements and passed the examination, can it be put into normal production and use, and the grinding effect and production capacity of the Raw Gold Processing Milling Machine are guaranteed. The two test methods of the Raw Gold Processing Milling Machine are described in detail below.

1, no-load test

Carry out full operation inspection of the Raw Gold Processing Milling Machine without feeding. Its contents are: electrical equipment and electrical interlocking system; lubrication, water supply, hydraulic station and hydraulic adjustment; inspection of the main part of the operation. The no-load test run meets the following requirements: start and stop according to the operating procedure, all relevant interlocking systems should meet the design requirements; gear transmission should not have impact and periodic noise; the forward and reverse rotation speed of the moving cone should not exceed 15r/min; lubrication The system works normally, the oil supply pressure is in the range of 0.05~0.1MPa, and the return oil temperature must not exceed 50 degrees Celsius; the hydraulic system works normally, and the ore discharge is adjusted to meet the requirements; the empty running time of the empty car is 2~8h.

2, loaded test

After the no-load test is completed and the requirements are met, the on-load test can be carried out. The on-load test is to check the inspection items in the no-load test under the conditions of the mine.

The on-load test should meet the following requirements: The on-load test should be carried out continuously for two days and nights (allowing a short-term parking check). At the beginning of the test run, a small amount of ore is added first, then gradually increased to full load; the ore is normal, the ore is evenly distributed in the milling cavity, the ore discharge is normal and close to the specified production capacity; the Raw Gold Processing Milling Machine vibrates sharply during normal operation. noise. In the case of “over-iron”, the non-grinding material can be smoothly removed; the hydraulic system works normally; the hydraulic system oil pressure is 0.08~0.15MPa, the oil return temperature does not exceed 60 degrees, and the wear parts are not damaged; The device is working properly.

In actual production, the Raw Gold Processing Milling Machine must be correctly tested in accordance with relevant regulations and standards to ensure that the Raw Gold Processing Milling Machine has higher milling capacity and working performance.
