Magnesium carbonate drying machine
Magnesium carbonate is a very important role in the chemical, food and pharmaceutical industries. The precipitated calcium carbonate is mainly used for filler in rubber products and reinforcing agent, insulating materials, fire prevention materials; pharmaceutical grade magnesium carbonate can be used for production of antacids; food grade magnesium carbonate can be used for flour improver, desiccant; in addition magnesium carbonate don't widely used in paints, ceramics, cosmetics production. Magnesium carbonate was prepared by calcination method, digestion method and carbonization method, and magnesium carbonate drying process is an essential part of it.
Magnesium carbonate dryers
In the dryig process of magnesium carbonate,after the removal of water to filter press. After the filter press after the moisture content of magnesium carbonate in about 75%. After the magnesium carbonate into the drying equipment for drying. On the choice of magnesium carbonate drying machine, a wide range of options is available. The earliest magnesium carbonate drying is mainly used in the tunnel type dryer, after being replaced by rotary kiln drying equipment.At present,in the drying process,it is mainly as the belt drying machine_Magnesium,about Watercress dryersOrganic pigment drying machineHuanQi dryersInstant rice noodle dryers and so on,it had best drying effect.See:Demonstration animation of multi layer belt dryer
Magnesium carbonate dryers
As basic magnesium carbonate dryers technology,is the use of belt dryer production. In the magnesium carbonate drying equipment, the selection of the belt type drying equipment has been adjusted slightly. The device structure is shown below:

In the magnesium carbonate drying equipment, the whole process of magnesium carbonate drying requires a large amount of heat source. The heat supplied by the indirect hot air furnace is provided with the material in contact with the material, and the temperature of the tail gas is about 250℃. This has caused a great waste. For this reason, we use the waste heat recovery device in the design of magnesium carbonate drying machine, and the tail gas is returned to the hot air stove. Special design of the air distribution structure, two layers of mesh belt of hot air and box in high temperature and low humidity air fully mixed, is air knife ejected from the air distributor. High humidity air fraction is still mixed hot air circulation, can effectively improve the thermal efficiency, avoid wet. The drying temperature is about 340℃, which can improve the drying rate, make up the heat loss caused by air volume. The three layer network with independent drive device, can set the material movement speed. The drying process of magnesium carbonate is in accordance with the drying rate and the energy loss is avoided.
