Raymond Mill Introduction

Raymond mill as the main equipment of grinding powder industry in our country, high reliability, energy saving, high precision and automation is the inevitable trend of its development. Can adjust the discharging granularity conveniently and flexibly, and the adjusting range is extensive.

Raymond mill is applicable to the grinding and processing of more than 280 kinds of non-flammable and non-explosive materials with hardness less than 7 and humidity less than 6% in mining, construction, chemical industry, etc.

The Raymond mill is widely applied in mining, building materials, chemical engineering and metallurgy industries for size reduction, dispersion, or specialized needs, powder generation and processing for industrial process.

raymond mill structure and working principle

Raymond mill structure is mainly composed of a host machine, a blower, analysis, product cyclone separator, piping device, motor and other components.

In addition, Raymond grinding mill structure also comprises a powder conveyer, powder feeding and metering equipment, powder collecting device, and the powder storage and packaging equipment etc.. The powder conveying equipment in Raymond grinder structure, ore materials from the storage point to the grinding machine to a classifier to the next level classifier arrow into a storage bin need powder conveying equipment, and a variety of powder conveying equipment.

Raymond mill structure also comprises a feeding device, the feeding machine is a device in discharging the storage bin mouth contact material can be discharged evenly, and then feed to the next device. Can say, the feeding machine is indispensable in the structure of the device of Raymond grinding mill. Collecting device is Raymond crushing mill process used to collect grinding quality powder equipment.

Operation Attention

  1. In order to make the Raymond powder machine is normal, should make the "equipment maintenance equipment safety operation system" to ensure the long-term safe operation of Raymond mill, maintenance tools and the necessary and grease and the corresponding accessories.
  2. It's grinding roller device for more than 500 hours to replace the grinding roller use time, the rolling bearing of roller sleeve must be cleaned, the damaged parts should be replaced promptly, gas tools available manual oil pump and a grease gun.
  3. When in the use of process, should be fixed personnel responsible for the custody, the operating personnel must possess a certain level of technology. Raymond grinder before installation of the operating personnel must carry out the necessary technical training, to understand the principle of performance of Raymond grinding mill, familiar with the operation procedures.
  4. After a period of time, should be carried out maintenance. At the same time repair replacement treatment on the grinding roller grinding ring blade wearing parts, roller device for a careful examination of the connecting bolt and nut should be in use before and after, to see whether the loosening, grease is to add enough.

Raymond Mill Unique Features

  1. Compared with other mill output power increase under the same 20-30%, Raymond pulverizer grinding pressure roller to material in high pressure under the action of the spring to increase 800--1200kg.
  2. Mohs hardness of less than mineral materials can be processed 9.3 stage crushing.
  3. Dedusting efficiency to meet national emission standards.
  4. Grinding device adopts chongdieshi multistage sealing, good sealing performance.
  5. Driving system of main frame adopts airtight gearing and pulley, drives smoothly and operates reliably.
  6. Finished product size range, the coarse particle size up to 0.613 mm (30 mesh) diameter up to 0.033 mm (425 mesh), a small part of the fine material can reach 0.013 mm (1000 mesh).
