LVM Vacuum Conveyor With Cone Mill

Vacuum Conveying

After starting the equipment’s vacuum system, a negative pressure is formed in the buffering material container. The materials in the fluid bed dryer are sucked into the buffering of the granulator through the feed pipeline under the action of the pressure difference, and then enter the mill and granulation system. This process does not require manual handling, reduces material exposure and cross-contamination, and is suitable for the GMP requirements of the pharmaceutical industry.

Mill and Granulation

After entering the buffering material container, the materials fall between the rotating knife set driven by a motor and the fixed screen mesh. The agglomerated materials are crushed under the shearing and impact forces of the rotating knife. Particles that meet the size of the screen mesh pores will pass through the mesh holes and fall to the bottom of the equipment; larger particles that do not pass through will continue to be repeatedly crushed until they reach the required particle size. According to the material properties, Senieer provides screen meshes of different pore sizes and allows adjustment of the knife set rotation speed to control the uniformity of the final particles.

Discharge Conveying

The uniform particles after granulation can be conveyed to downstream equipment in two ways: one is to use the equipment’s own or an external vacuum system to convey them to dryers, hoppers, etc. through negative pressure in the discharge pipeline; the other is to discharge them directly from the discharge port at the bottom of the granulator by gravity (suitable for docking with downstream equipment with short distance and low height). The entire process realizes the continuous operation of conveying, granulation, and discharging, improving production efficiency.
