Small Scale Gold Mining Equipment operation precautions

There is a basic principle in the operation of the Small Scale Gold Mining Equipment, that is, one look and three, four stable. The specific explanation is:

  • At first glance, look at the parameters of each measuring point of the equipment to determine the operation of the equipment.
  • Take care of both, that is, the kiln grinding should take care of both the water spray and the water spray of the humidification tower.
  • Three adjustments, namely adjusting the wind, seasoning and adjusting the speed.
  • Four stable, that is, stabilize the thickness of the layer, stabilize the vibration value of the mill, stabilize the grinding pressure difference, and stabilize the fineness and moisture of the product.

What are the operating points of the Small Scale Gold Mining Equipment?

  • Stabilize the thickness of the layer. The stability of the material layer can be achieved by controlling the air volume, the inlet and outlet wind pressure, the feeding amount and the water spray amount. In theory, the thickness of the layer should be 2% ± 20mm of the diameter of the grinding roller. In addition, the thickness of the layer depends on factors such as the particle size of the raw material and the gradation of the particles, the grindability of the raw materials, and the water content. If the average particle size of the feed is too small or the fine powder is too much under the condition of the height of the retaining ring, the layer will become thinner; if the average particle size is too large or the bulk material is too much, the layer will become thicker and grind. The machine load is rising.
  • Stabilize the grinding pressure. The Small Scale Gold Mining Equipment has a clear control range for the grinding pressure when it leaves the factory, but considering the influence of the particle size of the grinding material, the particle grading, the grindability and the wear degree of the grinding roller, it must be practiced in the production control process. Trouble to determine the appropriate grinding pressure control value. In addition, it is necessary to minimize the influence of the operator's human factors, avoid the one-sided pursuit of high production and increase the grinding pressure, so as not to affect the safe operation of the Small Scale Gold Mining Equipment.
  • Guarantee a certain grinding temperature. The Small Scale Gold Mining Equipment is a drying and grinding system. The temperature of the grinding is a comprehensive indicator to measure whether the drying operation is normal. In order to ensure that the raw material is well dried, the moisture content of the milled material is less than 0.5%, and the outlet temperature of the mill is generally controlled to be 90. C or so. If the temperature is too low, the moisture of the finished product is large, which reduces the grinding efficiency and the efficiency of the powder selection, which may cause condensation of the dust collection system; if the temperature is too high, it means that the smoke is cooled and humidified insufficiently, which may also affect the dust collection effect.
  • Control reasonable wind speed. The Small Scale Gold Mining Equipment mainly relies on the circulation of animal materials in the airflow, and the reasonable wind speed can form a good internal circulation, so that the material layer on the disc is proper and stable, and the grinding efficiency is high. However, the air volume is determined by the wind speed, and the air volume is related to the feeding amount. If the feeding amount is large, the air volume should be large; otherwise, the air volume should be reduced. The air volume of the fan is affected by the resistance of the system and can be adjusted by adjusting the fan valve. The pressure drop of the mill, the negative pressure of the grinding, and the negative pressure of the grinding can all reflect the amount of wind. Large pressure drop and large negative pressure indicate that the wind speed is large and the air volume is large; otherwise, the corresponding wind speed is small and the air volume is small. The stability of these parameters indicates the stability of the air volume, thus ensuring the stability of the bed.
  • Control the fineness of the finished product. The fineness of the finished product is affected by the speed of the separator, the air volume of the system, and the load inside the mill. In the case of constant air volume and load, it can pass 00Pa.
