Rotary valve-feeder is designed for dosed supply of large-sized materials with nodules size up to 30 mm, surface humidity not more than 1.5%, bulk density not more than 1.8 g/cm3, temperature from −50 °С to +250 °С.

Reliable dosing of materials by means of rotary valves is provided in case of continuous feeding the material from hopper into the loading branch pipe and absence of uncrushed parts in incoming material.

Rotary valves are designed in the following climatic versions: UKhL3, UKhL4, T3, according to GOST 15150-69 for economic needs and export. Rotary valves are available for operation in macroclimatic areas with moderate and tropical climate both in indoor and outdoor areas protected from atmospheric precipitation.

Rotary valve performs the following tasks:

  • rotary-valve feeder doses the material, it allows the large-sized material flowing through. It is possible to regulate the material feed by means of varying the rotor speed;
  • valve of ZShP-45 type represents housing with loading and unloading branch pipes and two side covers. Rotor with horizontal shaft is located inside. Rotor is of cylindrical form. It consists of two disks and blades between them. Blades form the individual cells. Shaft ends bear the bearings mounted into covers from the both sides. Dedicated labyrinth-and-cup seals are provided for shaft sealing in the places of output from covers, sealing air supply is provided to avoid the pulverized coal entry into sealants;
  • to allow the large-sized material pass through the rotary valve, its construction provides protective deflector limiting the level of rotor cell filling. Edges of rotor blades and housing are equipped with special cutting blades allowing to cut the material pieces and avoid possible seizure of rotor spinning in rotary valve;
  • gear motor equipped with frequency converter allows the drive adjustment from 10% to 150% of its rated speed and smooth start performance.
