Friends who have read the information will find that the HMB crusher does not install any cooling device, and the temperature of the powder generally does not exceed 45 degrees. How is this achieved?
In fact, we will understand the mystery after analyzing it. The heat generated by the pulverizer mainly comes from two aspects. One is the heat generated by the friction of the machine itself, and the other is the heat generated by the collision between the machine and the material. The HMB crusher is well-made, and the heat generated by the friction of the machine itself is negligible; and its crushing principle is clever, relying on rolling and grinding, not hard impact shear, plus its own low speed (only 285r / min), so The heat generated is much lower than other crushers. What's more clever is that the HMB's sorting airflow directly passes through the crushing tank. At the same time of sorting, it takes away most of the heat. There will be no higher temperature. In actual measurement, the wall temperature of the HMB grinder in continuous operation will not exceed 55 degrees, and the powder temperature will not exceed 45 degrees.
However, there are always exceptions. In June this year, a customer reported that the powder temperature of the HMB-701 crusher that had been in operation for one day actually exceeded 60 degrees. Our engineer went to check and found that the customer placed the HMB crusher in a small Completely closed environment, continuous operation for 8 hours. The heat dissipation of HMB is based on the flow of air. In a narrow and closed environment, the air does not circulate and the heat cannot be conducted out. The limited air is heated again and again. At that time, the indoor air temperature reached 50 degrees, so it caused The HMB also dissipates heat slowly. Under the guidance of our company's engineers, the customer rearranged the machine, and this problem was solved well. However, the engineers of Huanya Tianyuan also got an experience. Before installation, it is necessary to explain clearly to the customer the importance of ventilation for normal operation.
