How to Operate the Feed Mixer

The operator should well know the structure, performance and operating methods of the machine, and have received the training organized by Jiangsu Muyang. Each batch of material should be fed evenly in production and may not be sometimes more and sometimes less, so as to ensure the motor running under a rated load. After working, the paddle mixer must make an idle run for 1-2 min. prior to shutting down, so as to discharge all materials out of the machine.

If violent vibration occurs when the mixer is running, it should be stopped immediately to find out the cause and may only be restarted for work until the fault is eliminated. The temperature raise (refers to the risen temperature above ambient temperature) of the bearings for main shaft should not be higher than 35℃, and the maximum temperature should not be higher than 70℃ (ambient temperature should not be higher than 40℃). Carry out necessary cleaning and inspection when each shift of work is finished.

Materials cannot be fed until the rotor is running normally. Muyang refuses to responsible for all accidents that result from starting mixing machine with load Additives should be added in when half of the major materials has entered into the machine, and oil/fat should not be sprayed until all materials have entered the machine. Keep mixing for a certain period of time after spraying, and then discharge. When the machine is stopped and not to be used, oil/fat must be emptied out of the liquid pipe, so as to avoid pipe blockage due to oil solidification.

Metal or other large impurities should not be included in the material, or else rotor and paddles may be damaged. The speed reducer, cylinder and other accessories on the feed mixer should be used in accordance with the relevant stipulations in their operating instruction manuals. After a period of using, check the screws, nuts, and lubricating points for normal performance, and tight the other fasteners as well. Avoid overload running, so as to protect the main shaft from broken. Feeding amount of each mixing batch should strictly accord with that required in Table 2-2. Accident resulted for overload is not Muyang's responsibility. Before each restart, any residues in the mixer chamber must be emptied. Material cannot be fed until the rotor is running normally.

Muyang SJHS0.5B Double-circle Paddle Mixer

The SJHS0.5B Double-circle Paddle Mixer is widely used for mixing powdery and special granular materials in feed industry.

Main features and functions

The SJHS0.5B Double-circle mixing machine is a kind of horizontal batch mixer;
With patented rotor structure, it is characterized by Short mixing period and high mixing homogeneity: The mixing homogeneity of material within 60~90S amounts to CV≤5%, reduce the mixing period and improve the production efficiency; (Methyl Violet Stain (GB/T5918) method is used to test the CV value of mixed product).
Large variable range of filling factor: The Filling factor is between 0.4~1, applicable for mixing the materials with different specific gravity and granularity in various industries.
The shaft seal adopts the unique sealing technology, reliable seal, no leakage and long service life.
The discharge gates adopt full-length opening structure, which contributes to fast discharge and little residues.
The seal of discharge gates on the mixing machinery adopts the unique sealing technology, reliable seal and no leakage.
Available of rise and fall type liquid application system, which is convenient and rapid for cleaning and replacing spraying nozzles and can spray liquid evenly.
With air-return mechanism, the pressure difference between inner and outer of the mixer can be well balanced when feeding or discharging.

Transportation and Installation

1. Hoisting
It can be seen from the following picture how the mixing machine is hoisted by a traveling crane. The rope must be capable of bearing the weight of equipment, and too short a rope is not usable. The lifting ears for hoisting are provided.

2. Transportation
When the mixing machinery is to be delivered out of the manufacturer’s plant, it can be decided according to the practical conditions whether a packing case should be used or not. If the packing case is not used, rainproof facilities should be provided and it is necessary to prevent the equipment from collision and overturning.
If the packing case is used, the whole machine and accessories should be firmly fixed inside the case, and a certain distance between the machine and the walls of the case should be maintained to avoid collision or damage during transportation. If the equipment exceeds the height limit, it should be packed in parts.

3. Storage
When the paddle mixer is to be stored for a long time, it is necessary to put it in a ventilated, dry, shady and cool place with rainproof and damp-proof facilities. The exposed surfaces without paint should be coated by antirust oil.
