Product Introduction
High-strength milling machine is one of Raymond's milling machine series products.
High-strength milling is suitable for crushing barite, limestone, ceramics, slag and other Mohs hardness is not more
than 9.3, and humidity is below 6%. Non-flammable and explosive mining, metallurgy, chemical, building materials and
other industries of more than 280 materials for high-precision milling processing, the final product size is
adjusted in the range of 80-425 mesh (up to 1000 mesh). The special device added in the machine can produce coarse
powder of 30-80 mesh.
High-strength mill picture
Working process of high strength mill
In the high-strength grinding machine, a high-pressure spring with a pressure of 1000-1500 kg is fastened on the
grinding roller hanger. After starting work, the grinding roller rotates around the main shaft and rolls against the
grinding ring under the action of high-pressure spring and centrifugal force. The pressure is 1.2 times higher than
the Raymond mill under the same dynamic conditions, so the output is greatly increased. After the material to be
ground enters the grinding chamber, it is lifted by a shovel blade and sent between the grinding roller and the
grinding ring for rolling. After the rolling, the powder is taken into the analysis machine by the circulating wind
of the drum machine, and the qualified fine powder enters the cyclone with the air flow The powder collector is the
finished product, and the large-grain materials fall back to the grinding. The circulating wind returns to the
blower and repeats the above process, and the remaining wind enters the bag filter for purification. When the wear
of the grinding roller and the ring reaches a certain level, adjust the length of the high pressure spring to
maintain a constant rolling pressure between the grinding roller and the ring. So as to ensure a stable output.
Internal structure of high strength mill
High strength mill performance advantages
Simple process and strong independence
The high-strength mill adopts a three-dimensional structure, with a small footprint and strong completeness. It
independently forms a production system from block materials to finished powder.
Uniformity and easy maintenance
The fineness of the finished powder is uniform, and the pass rate is 99%, which is difficult for other milling
equipment. The electrical system adopts centralized control, the milling workshop can basically realize unmanned
operation, and the maintenance is convenient.
High wear resistance and reliable operation
Important parts are made of high-quality steel, wear-resistant parts are made of high-performance wear-resistant
materials, and the whole machine has high wear-resistance. The transmission device adopts closed gearboxes and belt
wheels, which have stable transmission and reliable operation.
