1 All the mechanical equipments produced by Jiangsu Muyang Group are equipped with safety devices, which are consistent with modern technical level and universally effective safety rules prior to exworks, so that the customers can use the machines in accordance with the regulations.
2 Enterprises are obligate to execute following regulations to guarantee operators' safety.
3 The coupling shield cap must be mounted and closed at any moment. It is very dangerous to personal safety, if they are open or disassembled. This point is also applicable for the preventive device of manipulator.
4 The safety limit switch should always be kept in good order. The safety limit switch may not be overlapped or discarded.
5 The grating cover plate, grid bar or guard grating on the mixing machines are usually installed and delivered together with the machine. They can only be disassembled with tools. And the machines with such kind of devices can be never put into work until the above-said devices have been properly installed.
6 The driving motor must be switched off completely when carrying out inspection, commissioning, repair and maintenance. This can be realized through a full-phase separating and lockable switch installed near the machine or on the operation desk and control panel on the site. It is not enough only to screw off the fuse wire!
7 If the machines need other energy like pneumatic, hydraulic, steam and hot water energy, it is necessary to cut off their energy supply or turn off the switch, and eliminate the pressure in the internal pipeline system of the machine.
8 As for handling heated or cooled parts and components of the pelleting machine, especial care should still be taken for the danger of burning possibility.
9 If you have pressed the emergency stop switch to stop the machine and you want to reset the switch, so it is not permissible to only re-press this button to restart the machine. And the machine can only be started by re-closing the main switch first.
10 If some machines are equipped with a local shutdown system, especial care should be taken. Read the instruction manuals attached with the machine carefully. In such machines with a local shutdown system, temperature will rise because of pressure or vacuum will occur after they have been used for a period.
11 If the operators employed cannot read or write, the owner has the duty to explain to them clearly where dangers exist and warn them that special attention should be paid.
12 The cleaning, lubricating and oiling of the grinding machine or its parts and components may be carried out only when the machine is stopped. If you must climb on or enter the machine to do such work, the mandatory provisions shall be made without exception: the power supply of motors must be cut off completely and the switch must be locked.
13 Be careful, sampling from inside the machine can never be carried out unless there is not any danger. Usually, the samples can be taken from the pipe under the machine instead of inside machine.
14 Clear off the deposited dust, dirties and materials frequently. Keeping the machine clean can enhance production safety and the cleaning level of workshop, and is also beneficial to dust explosion prevention.
15 If oil (grease) leakage occurs, clean it immediately and seal well the place where leakage occurs, and for oil or grease leaked on the floor will easily bring about hazards to the operator.
16 In production operation, the machine must be equipped with safety devices, which may be neither removed and abandoned nor reduced in functions. Otherwise, we are not responsible for any accidents resulted here from, and reserve the right to ascertain where the responsibility lies.
17 Please execute the special regulations on accidents prevention in the operating instructions provided us.
18 Only the trained professionals are allowed to operate the machine and equipment manufactured by Muyang.
19 Measures for environmental protection
If you decide not to use the machine any longer, the measures for environmental protection and reutilization should be taken: drain the liquids inside the extruder machine (like motor oil, gearbox oil, brake oil and coolant etc.) into special containers and send them to the preparation workshop. The plastic parts shall be picked out for reutilization. The metal parts shall be sorted out so as to be crushed or scraped.

MY56×2A Twin-Screw Extruder
The extruder is mainly composed of a feeder, a different diameter cylinder conditioner, an extruding device, simple pipeline system and electric control, see following picture.
The feeder is mainly used for feeding the material to conditioner in a certain amount, the equipped motor is of the frequency conversion speed control motor, and the rotation speed can be adjusted based on actual production situation.
The feeder of the extruding machinery is mainly composed of a convertor motor, a feeding bin, an anti-bridge device, a screw conveying device and a discharging out let, see following picture. The working procedure is: material in the feeding bin is pulled forward along the axial of the screw conveying device by the convertor motor, and then drop into the conditioner through the discharging outlet. At the same time, the anti-bridge shaft drove by the chain is rotating in the feeding bin to prevent generating blockage.
The conditioner on the extruding machine is made of complete stainless steel and mainly composed of a speed reducer motor, a feeding inlet, a water inlet, a steam inlet, a stirring shaft, a conditioning cylinder and a discharging outlet. Main features are shown as follows: two agitator shafts with different diameters and rotation speeds agitate the material through back cross movement, the agitation efficiency is good at that the material, steam, water or other liquid can be sufficiently mixed; and a housing with large volume is used so that the material can be kept long enough under a certain temperature and moisture content in the conditioner on the purpose for ripening.
Advantages of conditioning:
a. The production capacity can be improved.
The partially cooking material with steam needs a very less mechanical energy for heating products to the maximum temperature, therefore, as for a device with designated power, and the production capacity is greater than dry feed extruder with the same power.
b. The forming capability is greater.
The use of steam and water can make the water content of material be improved, and this will greatly improve the forming performance and final quality of the products.
c. The abrasion of extruding parts is reduced.
The cooked material has the corresponding temperature and ripeness, therefore, too much higher pressure and abrasion in the machine chamber are not required, and also the water can be used for lubricating, these can greatly reduce abrasion, so that service life of machine chamber and screw can be increased.
d. The gelatinization of product can be improved.
The steam cooking can improve gelatinization of produce, make it more taste and easier for absorption.
