Raymond Grinding Equipment

Raymond Grinding Mill Raymond Mill is suitable for grinding of all kinds of materials whose Mohâ??s hardness is below 9.3, such as calcium carbonate, barite, dolomite, calcite, limestone, kaolin, bentonite, marble, gypsum, quartz, feldspar, clay, talc, fluorite, clay, white mud, mica, refractory material, glass, total about 1000 kinds of materials. Raymond Grinding Mill Features: 1. High efficiency and precision classifier, unique airtightness, which canensure the quality of end products. 2. The wear-resistant volute can effectively improve the material liquidity, decrease the air volume loss and avoid air energy loss. 3. The bevel gear overall dive can achieve higher transmission efficiency, easy to install and adjust, long service life and lower cost. 4. Inner thin oil lubrication system can realize lubrication between main bearing and drive bearing without any additional lubrication pump, easy to maintenance. 5. The curved surface shovel with split design, only the blade to be replaced during maintenance, thus the shovel has long service life. 6. The isolated cyclone collector can effectively improving the classifying efficiency and accuracy. Working Principle : After the materials enter the grinding chamber of the main frame, the grinding roller swings outward and presses closely upon the grinding ring due to the centrifugal force generated by the rotation of the main shaft. The blade carries materials to the space between the grinding roller and grinding ring, and materials are ground as the grinding roller rolls. After being ground, the powder is selected by classifier via the cycle wind of the blower and the rough powder will be back to the grinding chamber for regrinding. The qualified powder is brought into the powder collector together with airflow. The powder comes out as end products while the airflow goes back to the powder collector in cycling to make the machine work normally. The remained airflow comes out after purification by dust filter.

The Application of Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment: Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment is the equipment specializing in producing fine and superfine powder of non-inflammable, non-explosive and brittle materials with Mohss hardness under six, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talc, mica, magnesite, illite, pyrophyllite and vermiculite, sepiolite, attapulgite, rectorite, diatomite, barite, gypsum, alunite, graphite, fluorite, rock phosphate, kalium ore, pumice, etc., totally more than 100 kinds of materials. Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment mainly consists of main unit, classifier, powder collector, dust cleaner, blower, muffler, sound-proof room, crusher, bucket elevator, storage hopper, and vibrating feeder. Working principle of Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment: After crushed by hammer crusher, the large materials become small ones and are sent to storage hopper by elevator, edge of then evenly sent to the upper distribution plate of the turnplate by vibrating feeder and sloping feeding pipe. When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers. The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the air flow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall an exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end. Features of Vertical Roller Grinding Equipment, Vertical Roller Mill Equipment 1. High efficiency 2. Long lifecycle of spare parts 3. High safety and reliability 4. High fineness and flexible adjustment 5. Environment-friendly

The purpose of the micro powder grinding mill is for super-fine grinding materials with hardness less than 6 in Mohs scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble,talcum, barite, gypsum, dolomite, bentonite mud,mica, pyrophyllite, sepiolite, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment and so on. The granularity of the end products is 325-2500 meshes (0.044-0.0055mm). Working Principle Of Micro powder grinding mill: The main bearing and each dial are driven by electromotor of main equipment through reducer, and numbers of rings and rolls which are rolling in the ring channels are driven by dial through plunger. After being crushed by hammer crusher, the big materials become small ones and they are sent to the storage bin by elevator. The electromagnetic vibrating feeder sends them to the middle of first dial evenly; the materials will be driven to the edge of dial by centrifugal force, and fall into the ring channels and are pressed, crushed and ground by the grinding rings and rolls. Then the materials fall into the second and third ring and crushed and ground. The high pressure centrifugal blower inhales air from the outside and blow the materials which are ground in the third ring to powder Separator. The rotating turbo in the powder Separator makes the coarse materials return to the mill and reground, while the fineness mixes with the air and be drawn to the cyclone and be discharged from the discharging valve which is in the bottom of it. The air which mixed with very little fineness are purified by impulse dust catcher and discharged by blower and muffler. Features Of The Micro powder grinding mill: 1. High-efficiency and low consumption With the same end-products fineness and motor power, its output is over 1 time of that of Jet Mill, Mix Mill, and Ball Mill. 2. Easy-damaged parts with longer working life The grinding roll and ring are made of special materials. Generally, their work life is more than one year, but, which could come up to over 3 years, when it processes calcium carbonate and Calcite. 3. Security and Reliablity Because there are no rolling bearing and bolts in the grinding chamber, we can not see the problems of bearings and sealings easily damaged and machine destroyed due to the bolts looseness. 4. Cleansing and Environment Protection Adoption of Pulse dust collector and muffler reduces the industrial dust pollution and noise, which reaches the National Standard.
