1. General Description

CXJ Microfiber crusher is this company undertake a research project in Zhejiang Province, in order to introduce Germany El Hobeur engineering technology development of a new generation of ultrafine fiber mill, filled the blank in domestic Microfiber grinding equipment. Its technology filled the blank in domestic reach international advanced level, for cellulose powder industry in China provides the ideal of Superfine grinding equipment. Germany El Hobeur is a professional engineering company engaged in the research and development of ultra-fine powder process technology company that has a history of more than 30 years, the development of ultrafine grinding device enjoys a high reputation in the international market,, its development of Superfine fiber grinder after a dozen years of actual operation and improvement, has now developed into an international one of the most advanced fiber grinding equipment.

CXJ Super fine fiber mill principle advanced: using advanced of air dynamics and Bionics design out of crushed device by high-speed rotating of dynamic knife and static knife composition, dynamic knife and static knife into a special of cut corner, through quickly cut to achieved on cashmere shaped, Floc, film, class fiber of crushed, production large, and energy consumption low, and crushed fine degrees good is many user select this equipment of a important causes.

2. Application and Characteristics

CXJ fiber mill is a kind of ideal for cashmere, wool Superfine grinding of fibre and cellulose ether products, such as refining cotton, cotton and linen, optical fiber, foam, rubber, films, etc. Widely used in chemical industry, plastics, rubber, paper and other industries ultrafine grinding of materials, plastic film, film, fiber material and heat-sensitive materials for ultra fine grinding. Product size most fine can be up to 200 mesh.

The characteristics are as follows:

1, using a special dynamic, fixed blade angle, by adjusting the blade clearance and screen density and dynamic control of product fineness and yield. Clearance adjustment range 0.5~1mm;

2, fixed, Fixed-Blade imported steel of high strength, impact resistance, good abrasion resistance, stable performance under conditions of high speed rotating cutting blade, with the blade to wear, long life and other characteristics;

3, the structure is rational, using computer-aided design cabinet with intracavitary airflow smooth, smooth, low noise characteristics, significantly reduced the fine material sticking to the wall;

4, material crushing is carried out at room temperature, by high speed rotation powerful airflow generated can be taken at the right time when the crush of heat generated, ensuring the crushing low temperature rise;

5, procedures, safety and reliability, maintenance, material clean up quick and easy;

6, high output, low energy consumption, the same material crushed its domestic energy consumption of similar models of 50%~70%.

3. Structure and Working Principle

This machine is a kind of high speed rotating shear Superfine pulverizer. It consists of a rack, the main body, move tool, plus hoppers, composed of gears and motors (as shown in the following figure), equipment belt feeder (metal detector), high pressure blowers, a cyclone feeder, filter and electric control cabinet, such as complete sets of Super fine crushing unit.

CXJ Super fine fiber mill of main work principle: material through Belt conveying machine sent to (in belt sent material of while for metal detection, prevent material in the entrainment metal debris) plus hopper Hou quickly is high-speed air with into dynamic knife and will knife composition of crushed area, high-speed rotating of rotor led dynamic knife by produced of powerful rotating air led material in dynamic will knife Zhijian campaign, and full dispersed reached Super fine cut crushed of effect, qualified material through sieve network discharge crushed area, does not qualified material and is high-speed air with into crushed area continues to crushed ; Item in the grinder stay within the total air surrounded in Superfine grinding process of inevitable heat taken away by high-speed airflow, achieve the purpose of crushed at room temperature, so that shattered chemical composition of material stability, performance does not change.

To reach the required fineness of the materials and production, you can replace the screen, adjust the cutter clearance and to use a different number of knives to achieve changes in yield and fineness of its purpose.

6.Product installation, commissioning and operation

6.1Installation and Commissioning

6.1.1, the company supplys CXJ-500 ultra-fine fiber mill hosts can provide equipment according to user requirements.

6.1.2, hosting and equipment be installed strictly in accordance with the flow chart location layout; each device should be joined firmly, pipe junction should seek to close to prevent air leaks, such as poorly sealed will not only produce dust pollution, and can cause your system to not function properly, affect productivity and product quality.

6.1.3, electrical control cabinet equipped with the equipment of the start/stop button, work lights, multi-point temperature control device, host, wind turbine meter, belt conveyor speed control knob and safety protection device indicates. Electrical control cabinet should be placed in easy to facilitate observation equipment functioning of control room electrical connection of lines between the device layout in accordance with national standards.

6.1.4. System sequence of operations:

Boot sequence: fan--> belt feeder-->--> host metal detector.

Stop order: belt feeder--> metal detection--> to stop feeding 5-10 minutes (you can observe the host meter, equivalent to an empty machine running current)--> host--> fan.

6.1.5, the micro-particle size of this equipment, adjusted according to the user requirement within a certain range, primarily to replace the thickness of the screen, adjust the grinding gap to fulfil the user requirements.

6.1.6, when the granularity to meet user requirements, and by observing the host meter, adjust the host load, load size can be achieved by changing the feed, keeping the main motor in accordance with best smash.

6.1.7, and pipeline within the host machine gun air flow sizes, can be achieved by adjusting the inlet valve opening. Air volume while it is being able to meet the production rate, generally no longer be adjusted.

6.1.8, aggregates should be configured with metal detectors, bag, specific actions as described in its instructions for use.

6.2Working conditions and safety rules:

6.2.1, working conditions:

1) ambient temperature-10~45°C;

2) not exceeding 1000 meters above sea level;

3) supply voltage 380V;

4) was crushed material moisture content ≤ 8%, and cannot contain other debris, so as not to affect product quality or causing engine damage;

5) feeding size determined depending on the material properties and the user testing.

6.2.2Security rules:

1) should check whether intra-host, before the power clean rotor rotation is flexible, shut down the good machine cavity, transmission parts indicator light shows the correct;

2) check join parts loose, the interface is sealing good, bearing cooling and gas seal is unobstructed. If there are exceptions, should be excluded until the power on;

3) when you want to check the host machine cavity internal working parts, you must cut off the main power supply, confirmed after a full stop of the machine in order to open the machine door, inspection and maintenance;

4) arrows mark the direction of rotation of the machine should be properly wired;

5) strictly according to the instructions provided for filling, replace lubricant.

7. Operation and Maintenance

1, every weekday after the completion of the compressed air blow off remnants of material in the cavity, and screen blows apart from cleansing, guarantee the next time you use material smooth;

2, crushed host room should be kept clean, prevents dust from entering affected the quality of products;

3, boot should be opened before bearing water cooling and gas bearing closed, cutting pressure is within the specified range (0.25~0.40Mpa).

4, the wheel bearings, high temperature, high speed grease lubrication, replacement of domestic quantitative joined must consist of professionals.

Cycle: first joined the bearing grease 650g, add 65g/grease after 600 hours of work, adding six times a year under normal circumstances. Grease should be replaced after every three months, you should rinse it through as far as possible to remove the used grease.

5, when the production rate decline, immediately cutting tool (knife, knives) grinding to ensure normal operation of the equipment.
