Currently people use in everyday life is relatively large, a Jet Mill is a large-size solid material was pulverized to a size standard, typically pulverized to micron level, we generally use the device is how means a composition, usually with thick broken, consisting of portions of a wind apparatus or the like fines. The main purpose is to use wind energy to become powder, which has canceled traditional screening when performing, and the main application is used in many industries such as mining or building materials. Some industries such as metallurgy or building materials, chemicals, etc. are used to work with large crushers.
Mechanical Steam Jet Mill equipment ultrafine grinding material is applied to depolymerization, the disposal material after extraction, the properties of the powder vary greatly, the performance of high viscosity, easy to agglomerate after impact. Powder is extremely prone to aggregation in the feed opening, pulverizing cavity and exhaust pipe, requires special treatment processes and specific design. Shandong Er Pieces Technology Co., Ltd. Design and developed materials and disseminated in the crushing of materials.
Mechanical Steam Jet Mill equipment by a high velocity jet of compressed gas feed nozzle the material particles generated in the hopper 3 to injection disc grinding chamber, the grinding chamber is provided around the plurality of jet nozzles only with direction of a high velocity fluid jet to produce ultra-high speed rotation in the opposite swirl crushing chamber. The coarse particles in the opposite ultra-high-speed swirls in the ultra-high-speed swirls produced impact and friction in the intersection, and the particles were quickly pulverized. When the particles are pulverized below the fractional particle size below the fractional particle size, the centrifugal force of the particle movement is reduced, and the grading swirling is separated from the center outlet under action, and is collected from the center outlet. Such a pulverizer, the motion of the particles can be decomposed into two components in two directions in the intersection. In one direction, the direction of movement of the particles is substantially consistent, and there is no significant impact pulverization effect, and only in the other direction, the particles are opposite, and the particles produce effective impact. Therefore, this impact of this intersection is limited, and the energy of ultra-high-speed moving particles is not fully utilized, so the production energy consumption is still high.
works Mechanical steam jet mill equipment: the jet mill and the cyclone fan primers constitute a complete grinding system, compressed air is filtered and dried, and then meet at a plurality of high-pressure air through the Laval nozzle at high speed into the crushing chamber. The material is repeated collision, friction and shear, and the pulverized material is pulverized in the fan pumping force. Under the action of the high-speed rotary classifier, the fine particles that satisfy the particle size required by the grading wheel are separated into a cyclone separator and dust collector to collect crude particles and dust collectors through the grading wheel with the thickness of the granularity. And continue to break in the broken area.
The high-pressure gas (compressed air, superheated steam or other gas) inverse from the pulverized chamber and the high-speed air flow consisting of solid particles injected into the crushing chamber were subjected to tangential impact of air flow injected from different angles. The solid particles collide with each other in the mixed airflow and refine it. Since the temperature generated during the pulverization is small, it is conducive to the low melting point crushing material. When toxic, flammable or radioactive substances are crushed, superheated steam is usually used to prevent outwardly spread.
This is because all materials can precipitate when steam condense. The gas flow pulverizer uses the material to achieve huge kinetic energy under the action of the high-speed airflow, causing severe friction between the high-speed collision and the particle, while the high-speed airflow generates shear effects, thereby achieving the purpose of pulverization.
a right, ready to check the host, accessory machines, pipes and valves before turning it on are intact , if it works.
Second, open
1. Turn on the compressor power supply, the pressure valve and the main air valve of the dust collector, then turn on the power switch of the powder machine, and turn on the power.
2. From the zero start grading wheel and gradually adjust to the specified speed.
3. Switching the fan, the cyclone separator discharges, dust removal, the power supply, and then turn on the total power supply of the barrel, set the inverter frequency, and then begins to break.
4. The particle size of the finished wheel can be adjusted by grading wheel frequencies and charging.
Third, the order of shutdown is: inverter - feeder - Main valve - Compressor - Steppered wheel Motor - Cyclone discharge, dust removal switch - Fan - Total Power - Air Compressor.
Fourth, repair
1. The motor should be lubed regularly, but the grease should not be too large, the bearing temperature is too high.
2. Hierarchical impeller, screw feeder, crushing nozzle wear should pay attention to check, belt tight and suitable.
3. After a crushing material, after a certain period of time, it is necessary to remove the viscosity of the chalk to avoid clogging, thereby affecting the crushing effect.
4. After the filter bag, you should clean or replace it.
V. Note
1. When the discharge device is running, the unloading port cannot be extended to avoid accidents.
2. The rotational speed of the impeller must not exceed the specified requirements, otherwise the temperature is too high, the impeller, and the electric machine are damaged.
3. Regularly check the safety valve to ensure safety.
