The SJHA4A Double-circle Paddle Mixer

Muyang double-circle paddle mixer is independently researched and designed by Muyang and wins international patent technologies. It has advantages of quick mixing time, high homogeneity and no residues.

The rotor of the SJHA4A Double-circle paddle mixer is equipped with two layers of paddles (4 big paddles with special angles in the outer layer and 4 small paddles with special angles in inner layer). The outer big paddles drive the materials to turn over leftward and rightward in fast-flow zone and make continuous circular movement in the through at all directions, keeping material mix evenly under the effect of strong convective mixing; the small paddles also greatly increase the convective mixing at slow-flow zone. In addition, the two layers of paddles can increase the effect such as diffusion, shear and impulsion in materials, so as to obtain fast mixing with high homogeneity.

The mixing machinery consists of rotor, machine body, machine housing, speed reducer, upper cover, liquid application device, access doors, etc. The rotor is installed on the machine body through the two bearings (with pedestal) at the shaft ends. It is driven by the output hollow shaft of the reducing motor. A discharge gate is installed at the bottom of machine housing, whose opening or closing is controlled by pneumatic cylinders according to the mixing cycle. The access doors for cleaning and maintenance are on the upper part of machine housing. There are two feeding inlets on the top cover for adding major materials and additives. The air-return duct is installed between top cover and the machine bottom.

Main Parts on Muyang PHGM200 Rice Extruder

The PHGM200 rice extruder mainly consists of a belt pulley and a hood shield, a main motor, an extruding device, a cutting device, a disassembling tool, an extruder base, a lubricating oil-way and a motor base etc.

Cutting device

By dint of side hanging, the cutting device can fasten the replacement of knives. The cutting device is composed of a knife assembly, a power unit and a supporting bracket. Generally, hard blades are used for this cutting device, and they can be adjusted forward and backward or upward and downward.

Extruding device

The extruding machine device is composed of a bearing pedestal, a feeding section, the first barrel section, the assembly of extruding chamber, a screw rotor and a discharging device.

Installation of electric control part

Adapted electric control cabinet of the equipment should be put on the chute side of the bypass, better to be 0.8 m ~1.0 m away from the bypass, without any spacing object in between.

It is incorrect to install the control cabinet far away from the principal machine or even right in the face of the material outlet of the feed extruder, or on the side of the main motor, because the operators must pass by the material outlet of the extruder to carry out operation. This violates the common practice that "it is inadvisable to stand in the front of the material outlet of the extruder" and may cause potential safety hazard.

For the installation of on-site power supply, the connection can be carried out according to the drawing of electrical control, and the motor can be adjusted for its forward and backward rotation. There is an indication mark of rotation direction on the hood shield of each motor.

In addition, for the layout of wire casing for the principal machine, we should consider that there may be water on the ground around the extruding machinery, so the wire can be laid overhead or embedded under the ground instead of placing at the ground beside the extruder, otherwise long period of water invasion into the wire casing may cause disastrous aftereffect and the exposed wire casing on the ground is also not favorable for site cleaning.

Muyang MUZL350T Pelleting Machine

This pelleting machine mainly consists of a feeder, a conditioner and a principal machine of pellet mill (mainly including a main motor, an Assembly of rotor, a ring die, press rollers, an assembly of cutting knives and a lubrication system).

The principal machine is composed of main motor, magnetic plate, Assembly of rotor, pelletizing chamber (including assembly of press roller, assembly of front plat and ring die), machine body, door and so on, Fig 1.5 shows the section of MUZL350TA type pellet mill.

Working procedure:

The mash with water content less than 18% as required enters the feeding auger from the pelletizing chamber in a proper feeding amount through adjusting the rotating speed of the frequency control motor, and then enters the conditioner. The material will be sufficiently mixed with steam in the conditioner by stirring paddles of the conditioner, and molasses or oil can be added through the feeding inlet for molasses if necessary. The temperature of compound mash is normally controlled within 65~95℃and the humidity 14~17% based on different formulas, and finally the material enters the pelletizing chamber and is pelletized to pellets by the press rollers and the ring die.

Muyang Vertical Emery Roll Rice Whitener

For Dampening Iron Roll Rice Whitener, the water is pumped by water pump from upper end of hollow shaft and atomized under effects of jetting air flow. The materials surface can be covered by a layer of water film, thus, the rice bran can be softened and then removed effectively. And the rice in whitening chamber can be cooled and the good polishing result of the white rice can be obtained.



Main features of Muyang MNMP21A Vertical Iron Roll Rice Whitener

1) The iron roll and the screw head adopt the split structure, which can be replaced conveniently.

2) This machine structure is compact and multi-machines can be in series for lightly whitening, without increase in hoisting equipment, thus can reduce the land use area and reduce the costs.

3) The feed machinery serving several purposes, not only can be used as iron roll to whiten brown rice, but also can be used as a polisher when it is equipped with a dampening device.

Requirement for installation site

The foundation for installing the grinding machinery should be strong enough to support the machine weight (see “weight to be transported”). The rice whitener occupies a land of 1.5×1.3 m2, around which 1 m wide empty area should be kept for operation and maintenance. In addition, 1 m high space should be kept above the machine for vertically taking out main shaft to replace bearing. The gate should be provided at feed inlet for guaranteeing the uniform flow rate.



The rice whiteners can be used in group for reducing the hoisting equipment and land use area.



During installation, use M16 foundation bolts (6 pieces) to fix the grinding machine and checkup whether machine for horizontality. If necessary, place an iron plate with certain thickness under the pedestal, in order to ensure leveling. The feed machine vibration can be avoided and the noise can be reduced by uniform stress. The floor shall be bored for installation of discharge pipe and electric cables.

Muyang Automatic Feeder

This Muyang automatic feeder mainly consists of a box body, a feeding roll, an adjusting plate, a magnetic gate mechanism, an impurity discharging hopper and others, as shown in Fig. 1.

Working principle

The material enters the trough of the feeding roll from top and is brought to the material outlet through a rotary roll and an adjusting plate, therefore, the feeding is continuous and uniform. A plate magnetic separator is mounted near the material outlet and can remove iron impurity from materials.

The feeding amount can be automatically adjusted. The control principle is as follows: A sensor detects the working current of the grinding machine real time, and transmits the signals to the controller of frequency conversion motor of the feeder, and then adjust the opening of the adjusting plate and the rotating speed of the frequency conversion motor through comparison with set current, so as to automatically control the feeding amount.

Installation procedures, methods and attention points

For installing the principal machine of the feeder, flanges are all used for jointing the upper inlet with the gate and the lower outlet with the hammer mill. A soft connection is recommended and the machine body should be kept horizontal. After installation, the feeding roll should be checked whether it rotates in the box body flexibly without any hindrance.

It is recommended to hang the controller onto the wall in the power distribution room for the grinding machine, and the screen is about 1.6m apart from the ground, for the convenience of operation and maintenance.

The current transformer delivered together with the controller should be mounted in the power distribution cabinet for the grinding machinery, and any one of power lines L1, L2 or L3 for the grinding machine should pass through the mutual inducting coil.

Functional Inspection Prior to Test-run

Before leaving the manufacture plant, a perfect test-run has already been conducted to the mixing machine. The initial test run in the user's factory cannot be done until following checks have been conducted. There should be no abnormal contact inside the mixing chamber or between the other accessories. All connecting points must be checked carefully to ensure there is not any looseness. Check the rotors for flexible rotation, and make sure there is not any abnormal sounds resulted from blockage, collision or abrasion etc. Check the rotors for their rotating directions matching with that indicated, for this it may need to start the motor for a short time; meanwhile, check the motor for any change in its rotating direction.



Check whether the emergency stop switch is in good working condition or not, safety switch of the access door As a part of the safety control of the mixing machinery, whether the safety switch of the access door works normally or not is directly related with the safety of the mixer, so the safety switch should be frequently checked for its functioning. Check the discharge gate mechanism for flexible rotation. When opening or closing the gates, there should be no abnormal sounds resulted from blockage, collision or abrasion etc.

Before each commissioning or after each unexpected interruption, the residual materials in the mixer chamber must be emptied. Only when the access door is closed and other related equipment is running, the principal machine of the paddle mixer can be started, and do not feed materials into the mixer until the rotor is running normally. Inch the mixer to check for any abnormal situation. If any, correct it. The temperature rise of bearing should not higher than 35℃ when ideal running for 0.5h, and the lubricating and sealing function still perform well. Check the running condition of the motor, which should be consistent with that required in its instruction. Screws, fasteners and lubricating points should be checked for normal performance after ideal running for 1 hour.
