Phosphorus is an important chemical raw material and an essential element for crop growth. The main mineral of phosphorus is apatite. If you want to process apatite with the output of 20t/h, you can choose the MTW European version mill of SMMVIK Machinery. This mill has a high efficiency in processing phosphate rock, and the capacity range is 3.5 - 25 t/h, which can fully meet the customer's demand for an hourly output of 20 t/h.
1. Apatite mill structure.
Working principle of MTW series European type pulverizer The whole machine is a vertical structure, with small floor area and strong completeness. The transmission device of the main machine is a closed gearbox, with stable transmission. The whole set of European type pulverizer is mainly composed of host machine, powder concentrator, fan, bucket elevator, electromagnetic vibration feeder, storage bin, pipeline device, cyclone collector, electric control cabinet, motor, etc. When the apatite mill is used, it is generally equipped with a corresponding bag filter, which is mainly used to handle the dust generated when the apatite mill grinds phosphate rock, so that the dust discharged into the air can meet the emission standard.
2. How to reach the capacity of 20t/h for the European version mill.
First of all, MTW series European trapezoidal grinding machine uses high wear-resistant alloy materials for its blade, which has a long service life. When replacing, only the blade part needs to be replaced, which improves the utilization rate of materials. The unit uses a forced turbine unit, which makes the grain size of the finished product expand from the original 80-325 mesh range to the 80-800 mesh range, and the product grain size is finer.
Secondly, the European trapezoidal mill adopts an internal oil pump, which can realize the lubrication of the main shaft bearing and bevel gear shaft bearing without additional oil pump or lubrication station. The lapping multi sealing device is adopted for the grinding device of the mill, which has good sealing effect, small dust emission and good working environment.
More importantly, the grinding pressure of the apatite grinding device on the material is increased by 800-1500kgf, so it is more applicable. The fineness of the finished product is finer, which can reach 800 meshes. The discharge particle size of MTW series mill is 1.6-0.045mm, and the fineness can reach 0.038mm. Under the same power, the output is increased by 10-30%.
