Brief Instruction of Airlock of flour milling machine

Airlock of flour milling machine is an important device for pneumatic conveying and dust removal. The main usage of airlock of flour milling machine is to timely and constantly unload the material from discharger or dust collector, and to prevent the outside air from entering the discharger or dust collector. Airlock of flour milling machine can handle materials in powder, pellet, flake shapes and also fiber materials. And at the same time, airlock of flour milling machine is widely used in rice milling, powder, animal feed, machinery, chemical engineering, medicine, tobacco, metallurgy and cement making, dust removal and many other industries.

Structure and Working principle of Airlock of flour milling machine

This airlock of flour milling machine  is a kind of improved impeller open type airlock of flour milling machine. It is a discharging machine structured with impeller, bearing, oil seal, airlock shell, end cover and other spare parts. On the top of the airlock of flour milling machine there is flange connected with the unload opening of discharger to receive the material from discharger, and then unload material from the bottom of airlock of flour milling machine while impeller rotating. The impeller is open type, which can prevent material from blocking as well as reduce airlock of flour milling machine weight and shape.   

  

Model Selection for Airlock of flour milling machine and Using Form

 Model selection basis for airlock of flour milling machine:

 1. Material granularity (powder or granule);

 2. Material viscosity(water or other liquids included);

 3. Material pH value(may select common material or stainless steel with different properties);

 4. Material temperature(select external type airlock of flour mill if above 60°C);

 5. Material handling capacity(Theoretical calculation of volume×1.2).

 Using form for airlock of flour milling machine:

Independent work by single airlock of flour milling machine( transmission by belt, chain or direct coupling), multi-machine series and in parallel. No more than 5 airlocks of flour milling machine in one unit when working by multi-machine in series or in parallel. The length of tandem shaft coupling and the height of bracket can be decided by users.

Installation and Use for Airlock of flour milling machine

Before installation airlock of flour milling machine must be carefully examined to make sure the impeller rotates flexibly and that relevant connecting parts reliable and correct. Then fix the airlock of flour milling machine on the floor or the bracket. Add full oil according to the using instructions if there is a reducer (3# Lithium-based lubricant). If a combination of airlocks of flour milling machine is used, there must be overload and short-circuit protection devices in order to prevent the damage of motor.

Before feeding, airlock of flour milling machine with separate power must be turned on before host machine, while airlock of flour milling machine without separate power should be turned on with host machine at the same time. And airlock of flour milling machine should be shut down after discharging of raw material.

Always pay attention to the observing window to see whether material flow is normal or not while running the airlock of flour milling machine. Timely treatment if accumulation.

Daily Maintenance and Repair for Airlock of flour milling machine

 1. Lubrication

 While installation of reducer for airlock of flour milling machine driving, the added lubricant should be fully unloaded one month later and add the new lubricant. Regular check for oil level keep. Lubrication for airlock of flour milling machine bearings can be done when equipment maintenance.

 2. Lutation

Both ends of the viewing window of airlocks of flour milling machine are U type rubber sealing rings, and they should be replaced immediately if damaged.

Oil seal is for the lutation of impeller shaft and end cover, which should be always checked. It should be replaced immediately if damage, otherwise the material will enter into the rolling bearing and thus cause bearing damage. Users are advised to choose airlock of flour milling machine with double oil seal and discharge opening.

 Lutation between impeller and air lock shell is the key point of airlock of flour milling machine. If the other place does not leak but material accumulation happens, it is mostly because of the abrasion between the impeller outer diameter and the inside holes of the device shell. In this caseusers shouldreplace immediately.

3. Teardown and Maintenance      

Correct methods for airlock of flour milling machine teardown:

1. Tear down by bolt;

2. Tear down by hammer. Remember to put copper bar or wood blocks on spindle head or end cover when teardown.

When replacing, first clean the end cover, then fit the machine with the same specifications of the oil seal and bearing. There must be full lubricating oil.
