LHW High Speed Pulverizer

Product Description

Working principle:
The rotor made up of several grinding disks, on which numerous vertical knives are installed; The layers of grinding disk form staggered packings, which are the small crushing chambers, when it runs, the circumferential velocity can be 84 m/s and the stream velocity between rotor and liner 55 m/s, and the vibration frequency for crushing chambers 4000-15000 times/second. All these mentioned above will lead to produce 140bd ultrasonic wave, 0.025 partial pressure differences and sonic jet current and vortex, which are very helpful to size reduction of material under the action of impact and friction happened between particles in the inner. Practices show that both grinding efficiency and fineness of products for eddy mill are superior to conventional impact mill. The ends of rotor are separately assembled with an impeller of blower; The lower impeller is used for absorbing material and speeding up material via high speed air and the upper for transporting ground material. The rotor is mounted with layers of cutter saddle, on which the withdrawable knives are fixed, and the stator is mounted with zigzag liners, a return tube is mounted on the machine, the unqualified powder will be rejected into crushing chamber by classifying system via feeder.

Features

1. Can be used for grinding medium and low hard material and especially for micronizing especial materials, it can also be in conjunction with heating or cooling system.

2. The vertical type with no screen, the motors for the machine can be selected according to the different technical requirements.

3. Being balanced statically and dynamically, the assembly of rotor operates quietly; Therefore the system can be placed on the flat ground or supported by shock pads without foundation.

4. The machine can continuously operate with classifier, cyclone, bag filter and draft fan, among them, the filter can be impulse type whose collection rate can be 99.5% and feeding system be an automatic screw conveyor or controlled by a frequency transducer.

5. All the wear parts are made of wear-resistant steel.

6. Being equipped with classificators, the fineness of the product can be adjusted by increasing and reducing the quantity of classificators.

7. Being equipped with a return tube, the flow rate of material can be controlled and the fineness of product can be adjusted without closing down.

8. Easy installation, maintenance and operation and high production capacity.

Application

The advanced eddy mill featured by quiet operation, low consumption and high efficiency, a kind of continuous grinding equipment combining ultrasonic comminution and dryness, salving the lasting, complex and hard-to-solve problem that special organic matters such as PVA, PVC, PE, fabric materials, or heat sensitivity and low-melting-point material such as magnesium can not be milled at normal temperature as well as plenty of chemical products, dyes, vegetable fibres, Chinese medicinal herbs, non-metallic mineral products and foods can be milled by conventional crushers. The fineness of some products can be 3-5 micron. It fills the domestic gap that most special materials can be not micronized, reaching the international standards instead of the imported product.
