Brief Introduction

Best quality new Raymond mill, after years of practice and improvement, has perfect structure, high efficiency, low consumption and small coving area such advantages. Raymond grinding mill is popular around and broadly used on the mineral powder processing in metallurgy, building materials, chemical, beneficiation, road and other mineral fields. Xinyu high efficiency mining machine stone Raymond mill is suitable for processing non-flammable and explosive mineral whose Moh’s hardness is not more than 9.3 and humidity is less than 6%.
High-efficiency mining machine stone Raymond mill’s whole structure is composed of mainframe, analytical engine (classifier), plumping, blower and cyclone separator; the mainframe is made up of frame, inlet volute, relieving tool, grinder roll, grinding ring, cover piece and motor.
 
Working Principle
Materials after being crushed achieve the demanding granularity will be brought to the storage hopper by hoister and then feed into the host grinding chamber quantitatively, evenly and continuously by vibrator feeder. Due to the centrifugal force of the rotating, roller swings outward. The blade brings materials to the middle of grinding roller and grinding ring. In this way the materials are grinded by the rolling of grinding roller. Then powder is taken away by the fan and graded by analysis machine. Powder in line with the demanding fineness will flow into the big cyclone collector by the airflow to be separating collected, at last discharge from the powder tube and this is product. In the grinding chamber, grinding material has certain moisture. The grinding heating makes the moisture evaporation and due to the pipeline interface is not tight, air is sucked into which makes the circulation pressure increasing. In order to ensure the Raymond mill grinding machine’s working condition is under negative pressure, the increasing gas will flow through ductwork into dust catcher and then out to the atmosphere after being purified.

Features

1. Raymond mill is vertical mill for phosphate rock and covers a small area which is a complete set. It is an independent system not only on the rough machining of raw materials but also on the final packaging.

2. Compared with other mills, Raymond mill’s sieve rate is higher up to 99% which is not easy to achieve by other grinding mills.
3. Raymond mill mainframe has been improved. The principal axis has transformed structure to be more stable which makes operation reliable.
4. As professional limestone grinding mill, Raymond mill’s main parts adopt high quality materials and have exquisite workmanship which ensures the high efficiency and good wear-resisting performance.
5. Electric system adopts centralized control. Raymond mill grinding work can achieve unattended operation basically and its maintenance is convenient.
