LM Vertical Grinding Mill VM series Vertical Grinding Mill is a kind of large scale powder mill which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of research of mills, vertical grinding mill is designed and manufactured based on our advanced design idea, in combination with the european technology and the market demand. VM Vertical Roller Mill adopts reliable structure and reasonable process flow, integrated with drying, milling, classifier, elevator. Especially, it can fully meet the requirement of clients of the high production of powder, and its main technical and economic indicator reaches the international level.

Features:

Low running costsIt adopts the technology that vertical roller grind material directly on the disc, with low energy consumption; for the roller is not contact with the disc directly in the work, and the roller and liner are made by quality materials, it is of less wear and long life.

Simple and reliable operationIts automatic control system can reach remote control, which is easy to operate; there is the device to prevent roller sleeve contact with disc liner directly, and avoid the destructive impact and severe vibration; we can turn the rotating arm by repairing fuel tank, replace the roller and liner are more convenient, which can reduce the downtime.

Energy conservation and environmental protectionIt features small vibration, low noise, and sealing device as a whole, and the system also works with no pressure and dust spills.

Working Principle:

The motor drives the grinding table through decelerator. The materials fall down the center of grinding table from feed opening. At the same time, hot air comes into the mill from the air inlet. Due to the centrifugal force, materials move to the edge of the grinding table. The materials are pulverized by the roller when by pass of the groove on the grinding table. The crushed materials are brought up by vane high-speed airstream, the larger particles fall down to the grinding table for regrinding. When the materials in the airstream pass the separator on the top of the mill , the coarse powder fall down the grinding table for regrinding under the function of rotation rotor. The fine powder comes out with the airstream , and is gathered by the dust catcher. The materials content with moisture will be dried when they meet the hot airstream. Through adjusting the temperature of the hot airstream, it can meet different materials requirement, and also through adjusting separator , it can reach proper fineness of materials.

Micro Powder Grinding Mill

Micro Powder Grinding Mill    Description:

Micro Powder Grinder has been widely used in making fine powder or micro powder, the Ultra Fine Mill is a new kind of Micro Grinding Machine. SCM Ultra Fine Grinder is applicable to non-flammable and non-explosive materials with hardness less than 6, such as the calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, magnesite, illite, pyrophyllite, vermiculite, sattapulgite, rectorate, diatomite, barite, gypsum, alum earth, graphite, fluorite, variscite, potash ore floatstone,etc. As one of the best grinding mill manufacturers, Dingbo has developped and manufactured more and more advanced grinding machine. The SCM super-micro grinding mill is kind of popular micro milling machine. The ultrafine mill is invented by absorbing advantages from the same trade home and abroad.

Working principle:
After crushed by hammer crusher, the large materials are crushed into small ones and sent to storage hopper by elevator, and 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 airflow 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 and 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.

Micro grinding mill Features

This ultrafine mill is of lots features and benefits, such as the high efficiency in same condition of finished particle size and power of motor. The output of the micro milling machine is 40% higher than airflow mill and whisk mill. In same condition of material and finished particle size, the quick-wear part of the ultrafine mill is of high using rate and longer lifetime than traditional milling machine. Because there are no axle tree and bolt in the grinding an trum, there will be no wear out of bearing and sealing part and also no loose of bolts which will greatly improve the safety of the micro milling machine. What's more, the ultrafine mill will greatly lighten polution and noise by using dust cleaner and muffler, which has achieved environmental protection requirement.

Raymond Mill

Raymond Mill  

Raymond Grinder has almost several tens of years history. Raymond Mill Machine is collocated with jaw crusher, elevator, electromagnetic vibrating feeder, main unit, classifier, collector, cloth deduster and high-pressure blower and so on. We also offer spare parts and original wear parts related to the Raymond Mill. After years of practice and improvement by manufacturer Shanghai Dingbo Machinery, the structure of Raymond Mill is getting perfect by blow consumption, low investment, environment friendly, small occupation area, and more efficient than the traditional industrial grinding mill.
The Raymond Grinding Mill is used to grind materials in the fields of building materials, mining, metallurgy and chemical industry. The materials must be non-flammable and non-explosive materials such as: limestone, calcite, barite, dolomite, potassium feldspar, marble, talcum, gypsum, kaoline, medical stone, rock phosphate, manganese ore, iron ore, glass, ceram, active carbon, carbon black, fireproof materials, heat preservation materials, chemical materials and so on(300 kinds of materials). The materials should have the hardness less than 7 in Moh's scale and humidity less than 6 percent. The granularity of the end products can be adjusted from 30 to 325 meshes.

Working Principle:
After the materials enter the grinding room of the main equipment, 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 roll 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 room 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 catcher.
