SCM series super thin mill also caller ultrafine grinder mill is on the bases of our company’s production experience for more than 15 years. We absorb advantags from the same trade abroad and at home. We review, research and try on 12 kinds of mills and horizontal hammer crushers. And finally we developed this high-efficiency and low-cost super thin mill by investigation and trial.

During the application of grinder mill, some personnel shall be arranged to take responsibility of management. The operators must be qualified with the required technical knowledge. Before the installation of grinding mill, the persons related to the operation should receive technical training and fully understand the operating principle, performance and regulations of grinding mill. In order to guarantee the grinding mill in a normal working state, a safety operation system for the maintenance of grinding mill must be established. Only in this way can the grinding mill be guaranteed to have a long-term and safe operation. Meanwhile, it is necessary to have the required repairing tools, lubricant and grease, spare parts and accessories.

SCM super thin grinder mill (ultrafine grinder mill) is a equipment which produces thin powder and super thin powder. It is applicable to non-flammable and non-explosive materials with hardness less than 6, such as calcite, chalk, limestone, dolomite, kaolin, bentonite, talcum, talc, magnesite, illite, pyrophyllite, vermiculite, sattapulgite, rectorite, diatomite, barite, gypsum, alum earth, graphite, fluorite, variscite, potash orefloatstone.

1. High efficiency. Under the same condition of finished particle size and power of motor, the output of thin grinding mill is 40% higher than airflow grinding mill and whisk grinding mill.
2. Environmental protection. Pollution and noise are lightened by using deduster and muffler so as to reach the requirement of national environmental protection when using thin grinding mill.
3. High safety. No axle tree or bolt is used in the grinding chamber, so there will be no worn out problem of bearing and sealing parts, and also no loose of bolts in the running of thin grinding mill.
4. Finished size can reach to d97≤5μm.
5. High using rate of spare parts.

The whole system of SCM series super thin grinder mill (ultrafine grinder mill) consists of main unit,deceleration machine , blower ,hammer crusher,dustpan elevator,electro-magnetic vibrating feeder,impulse dust cleaner,piping device, cyclone collector device,classifier,high-pressure motor and muffler.
Axletree seat and effuser air-in are built on the main seat.The antrum of mill is on the effuser air-in.Multi-layer dial set on the main axle lies in the middle of grinding antrum.There are sevel rollers distributing evenly on each dial.A gear reducer and motor are set on the main seat,while the powder collector is set on the top of the antrum mill.

The main motor drives main axle and every layer rotating by the power of reducer. Dial drives numbers of rollers rolling and rotating in the ring by pintles. Big materials are crushed into small particles by hammer crusher.

Then they are sent to store house by elevator. Vibrating feeder send the materials evenly to the middle of the upper dial. Under the function of the eccentricity, the materials fall into the ring to be pressed, crushed and milled into pieces by rollers. After the first crush, materials fall into the second and third layer. The pumping of the high-pressure centrifugal blower put the outside air into the grinding machine. The coarse powder will be brought into the classifier.

To make grinder mill normal operation and maintenance , the choice of lubricants, use, storage is very important. Because of the lubricants ,we can avoid direct contact with the surface of grinding mill parts and reduce friction , wear and tear. While taking advantage of thermal conductivity of the oil ,the heat generated by friction can be passed. So it should be kept clean and a certain degree of viscosity of lubricating oil, when ensuring adequate and smooth flow. If you need to stop grinding mill for a longer time, you should pour the balls out, to avoid the tube bend. In cold areas,such as in winter, you should release bearing cooling water in order to avoid frost crack.

Note: This specification is just reference, any changes are subject to the ultrafine grinder mill products.

1. There should be a lifting facility with the capacity above 2 tons. The height of lift should not below 6 meter.
2. There should be a reinforced concrete for main unit and blower. There is no need of reinforced concrete for double cyclone collector and impulse duster, but you should make a hardened ground for them, and fix them with expanding bolts.
3. The contacting flange for each pipe should be parallelization, and put the resilient sealing pat, rubber, or glass sealant between the flanges.
4. The diameter of electric wire should be matched with each motor’s rated current.
5. After finishing the equipment installation, you should first check if there is bolt, nut or some other something in the machinery.
6. Firstly, you make each machine run slowly by hand, after you feel it works normal, you can start electric motor.
7. Run each machine separately to check that there is something wrong with the switch.
8. Referencing the sketch two, check the rotating direction of blower, classifier and main unit.
9. Start the blower and check pipes and their joints to see if there is air leakage. The whole system is running under the negative pressure, and the air is absorbed form outside, if there is a leakage on the pipes or their joints, it will low the capacity or even stock the main unit. So, it is necessary to check it seriously.
10. Fix all the fastenings.
11. Adjust the motor coupling, and the proper alignment of main coupling is Φ0.05mm.
12. The level of framework and motor bottom is 0.065mm.
