High strength grinding mill is a new type of grinding mill introduced by FTM. The large-scale milling machine is especially suitable for the desulfurization of various large-scale thermal power plants and steel mills, and mining and building materials industries. Currently, hot sale types in the market are high strength 96, high strength 95, high strength 93, high strength 86, and high strength 83.
High strength grinding mill is suitable for crushing barite, limestone, ceramics and slag, with a Mohs hardness of not more than 9.3, and a humidity of 6% or less in the fine powder processing of non-flammable and explosive mines, metallurgy, chemicals, building materials, and other industries. The finished product size is adjusted in the range of 80-425 mesh (the finest 1000 mesh). A 30-80 mesh coarse powder can be produced by adding special equipment inside the machine.
In the high strength grinding mill machine, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the roller hanger. After starting work, the grinding roller rotates around the main shaft, and under the action of the high-pressure spring and the centrifugal force, it is pressed against the grinding ring, and the pressure is 1.2 times higher than that of the Raymond mill under the same dynamic condition, so the output is greatly improved. When the material to be ground enters the grinding chamber, it is shoveled by the blade and sent to the grinding roller and the grinding ring for rolling. After rolling, the powder is brought into the analysis machine along with the circulating air of the blower, and the qualified fine powder enters the cyclone powder collector as the finished product, and the large granular material falls back to the regrind. The circulating air is returned to the blower and the above process is repeated, and the residual air is purified by the bag filter. When the wear of the grinding roller and the grinding ring reaches a certain level, the length of the high-pressure spring is adjusted to maintain a constant rolling pressure between the grinding roller and the ring, which ensures a stable output.

1. Three-dimensional structure, small footprint, strong set, from block to finished powder independently into a production system.
2. The fineness of the finished powder is uniform, and the screening rate is 99%, which is difficult for other milling equipment.
3. The important parts are made of high-quality steel, and the wear parts are made of high-performance wear-resistant materials; thus, the wear resistance of the whole machine is high.
4. The electrical system adopts centralized control; the grinding workshop can basically realize unmanned operation and the equipment is easy to maintain.
If your machine fails, production at the entire plant will be at risk. To avoid such
losses, you can get critical replacement parts of the machine whenever you need it.
Our products support global logistics network distribution, ensuring that FTM brand spare parts or consumables are available when you need it.
Our fixed-model machines and consumables are available from stock to ensure customers
get the machines they need in time.
