Inquiry
KY-30 Co-Rotating Parallel Twin Screw Extruder Machine Group （L/D=32）

Introduction

 

 

KY-30 Co-Rotating Parallel Twin Screw Extruder Machine Group （L/D=32）

Product Of Main Extruder：Food.

Capacity Range：50-70kg/H (Different According To The Formula Of Material)

Voltage: 220V – Frequency: 60Hz

Technical Parameters

  KY-30 Co-Rotating Parallel Twin Screw Extruder

1. Main Motor：

1.1 Manufactured by WanNan motor factory;

1.2 AC motor，power 7.5KW,rpm 980r/min;

1.3 Cooling mode; Fan cooling; Environment temperature≦40℃;Install Height≦1000m;

 

2. Gearbox：

2.1 New structure gearbox, high torque, high speed;

2.2 Splined sleeve to connect with the Screw;

2.3 Use imported brand bearings. Integrated thrust bearing for load sustainability

2.4 The bearing and gears are forced to adopt the immersion oil-lubrication system. No cooling oil pump;inside the gearbox has cooling coil to be connected with the running water.

2.5 Speed: 100 – 400RPM.(i=2.5)

 

 

3. Feeder:

3.1 Single-screw metering feeder, double-headed structure; feeder screw diameter: ~40mm.

3.2 No grade variator 0.75kw, RV series reducer is adopted.

3.3 Stainless steel silo.

 

4. Screw Elements:

4.1 Screw element involute link, single-head structure for food

4.2 Diameter of screw 30.2mm, L/D=32, quantity of barrel 8

4.3 Ratio of screw 400r/min

4.4 Material W6Mo5CrV2 Hardness HRC60-62

 

 

5. Barrel：

5.1 The barrels are made by manufacturing center and the aligning pin and inner hole are completed by manufacturing center in one time. Inner hole is 6 grade which is a high precision. After assembly, the concentricity error is 0.05mm, thus greatly enhance the self-cleaning of screw and reduce energy consumption;

5.2 The barrels are equipped with stainless steel integral shielding which are secure, good-looking and power frugal;

5.3 The barrels are produced with bimetallic alloy cover：HRC60-62;

5.4 The barrels (except feed barrel) adopt cast-aluminum heaters. The barrels use soft water cooling.

5.5 The first (1) barrel is feed barrel, the fifth (8) barrel is extrusion barrel and the rest barrels are closed-mouth barrel.

 

 

 

 

6.Barrel Temperature Control System：

6.1 Heating and cooling is controlled by temperature control meter through the solid state relay or electromagnetic valve, thus form a closed-loop system to control the barrel temperature. The temperature control accuracy is ±1℃ and control the flow by stop valve;

6.2 Two cooling water pipes. All the cooling pipes and joints are of stainless steel; Soft water circulation system.

 

 

 

7.Air Cooling Hot-Cutting Palletizing Machine(Refer To The Buyer’S Drawing Paper):

7.1 Air cooling hot-cutting extrusion head;

7.2 Concentric hot-cutting template, the numbers and diameters of holes is based on the buyer’s drawing paper;

7.3 Stainless steel air cooling hot-cutting cover;

7.4 Pelletize motor power 0.37kW with Delta Frequency Inverter to control the speed.

7.5 Install Copper on the part that move the motor and that part the fix the flange

 

 

 

 

  Electrical Instruments Control System

 

1.Control instruments adopt the following brands：

1.1 Temperature control meter: Japanese Shinko;

1.2 Main Frequency Inverter: Taiwan Delta;

1.3 Main Control Switch: LG;

3.General illuminated button indicate switches:

3.1 Emergency stop switches;

3.2 Alarming reset;

3.3 Main motor start;

3.4 Main motor stop;

3.5 Oil pump start;

3.6 Oil pump stop;

3.7 Water pump start;

3.8 Water pump stop;

4. LED Indicator:

4.1 Power LED;

4.2 Main extruder fault LED indicator;

4.3 Main extruder over-electric current LED indicator;

4.4 Main extruder over-pressure LED indicator.

5. Digital display and controller:

5.1 Temperature control of all sections;

5.2 Main motor electric current;

5.3 Rmp of twin screw.

The Above Configuration Power Voltage Only Confine To Standard Power Supply 220V 60H.
