Raymond Mill

Jaw Crusher

Introduction

Raymond Mill has a strong performance of becoming a complete set with a production system independently.

Feed Size

25-35mm

Capacity

3-22T/h

Product improvement

All important parts of raymond mill are made of high quality steel, and all wear-resistant parts are made of high-performance wearresistant materials. The whole machine has high wear resistance and reliable operation.

Advantages

  • Force produced from milling roller connected by pull rod and high pressure spring can avoid damages caused by bulk materials to the equipment. Resilient coupling between main engine and the separator can reduce vibration and noise and improve service life of the equipment.
  • Because of connecting crushing, drying, grinding, classifying and transmission together with simple system and compact layout, it covers about 50% of the area of the ball mill system and can be outdoor arrangement, which can reduce the investment cost a lot.
  • Milling roller devices adopt superimposed multistage seal with excellent seal performance.
  • Unique air circulation system with advanced dust remover carries the environmental protection concept through to the end.
  • Impeller devices with high density and high precision increase more than 50% of finished product yield under the same power. Efficient and energy-saving centrifugal induced draft fans improve the efficiency of induced draft fans greatly. Convenient impeller adjusting devices improve the precision of the finished product.

Application

Mainly used for powder processing of materials in such industries as construction, chemical, metallurgy, mine, thermal power and coal.

All kinds of non-flammable and non-explosive materials with the Mohs hardness of no more than 9.3 and humidity of below 6%, such as cement (raw materials and clinker), coal, talc, feldspar, quartz, slag, mica, calcite, limestone, barite, potassium sulfate, and bentonite.

Working Principle

Large bulk materials crushed by jaw crusher to the needed size are fed into storage hopper by mine hoist and then fed into grinding chamber of main engine uniformly, quantitatively and continuously by electromagnetic vibrating feeder for grinding. Grinded materials are blown into separator by blower for classification. With the function of impellers in the separator, materials without meeting the requirements of the fineness are fallen into grinding chamber for grinding again; materials meeting the requirements of the fineness are blown into cyclone powder collector with airflow through pipelines for separation and collection. Powder from discharging device is the finished product. Separated airflow is back to blower through return duct on the top of the cyclone powder collector.
