MTM Series Medium Speed Trapezium Mill

MTM series milling machine optimized the inner structure and lots of core devices and both the spare parts cost and breakdown time are obviously reduced. The new supercharging device can greatly increase production capacity. According to hundreds of customers' feedback, MTM series grinding mills are quite good at producing 60-325mesh powders and is quite hot in many countries.

Cost Saving

The constant grinding pressure can be maintained between grinding roller and grinding rings by adjusting the length of the compression spring, which can increases the utilization rate of roller ring to save the material costs.

High Quality

The grinding roller assemblies are connected by horizontal tie rods and springs, with the radial force applied to protect the main shaft and bearings against the impact from large-sized materials in the grinding chamber. The rolling force is 1.2 times higher than that of the Raymond mills in the same conditions, so the capacity is greatly improved.

High efficient balancing and pressurizing spring

The main mill and powder classifier are combined by braid connection. The damping springs and sealing tapes are used to reduce the vibration and noise and also avoid resonance.

Environmental protection

A variety of de-dusting equipments are available, with the emission standard higher than the national standard.

Working principle

The host drives the central shaft running (Fig. 3) by the gear box. The upper end of the shaft is connected with a wobbler spindle and the grinding roller is suspended under the wobble spindle by a cross arm shaft and forms a swinging point.

The grinding roller runs along with the central shaft of the whole machine, and also rotates by friction with the grinding ring. A perching knife system is installed under the wobble spindle and feeds the material into the gap between the grinding roller and ring for pressing and grinding with the grinding roller during rotation.

(Fig. 5) Air flow will bring minor powder into the powder concentrator upon entry into the grinding gravity from the bottom of the grinding ring. Coarse materials fall down and are reground; and fine powder goes into the powder collector along with the air flow and is discharged as the finished product through the powder discharge tube.
