Purpose:
The Mixer ЗСЛ-4000 is designed for blending the premix components after these ingredients have been dosed. It's suitable for mixing mineral fertilizers. The Mixer can be applied at the turnkey feedstuff plants and enrichment mixtures production workshops.
Dimensions of the individual mixing components should be in the range of 0.1 to 3.0 mm. It perhaps to make Mixer Н-ЗСЛ-4000 for mixing of premix and food components. All the parts are in contact with the mixing products is made of stainless steel.

Principle of operation ЗСЛ - 4000:
The principle of operation is that the fillers entering the mixing hopper accumulate until the portion/level is reached, then the dosed components are manually loaded (a short loading time prevents the effect of component separation), in the mixer housing, the components are subjected to intensive counter mixing with blades when the rotor rotates. After the mixing time has elapsed, the bomb bay opens and the resulting mixture is sent to the place of unloading from the hull. Unloading is controlled manually or using automation / computer.
Design of Mixer ЗСЛ - 4000:
The mixer consists of: body (1), rotor (2), drive (3), discharging hatch (4), pneumatic drive of discharging hatch (5), discharging hatch support device (6).
The body 1 is a semi-cylindrical steel welded structure. In the side walls of the mixer body there are windows closed with covers, limit switches interlocked with the electric motor and intended for repair work, visual control and periodic cleaning of the mixer from the inside with a scraper and pneumatic device.
Rotor 2 is a shaft on which 6 blades (scrapers) are located. The blades are located at certain angles, which provides intensive mixing of the loaded product. The rotor shaft is supported by bearings that are mounted on the mixer body. Drive 3 provides a given rotor speed from the electric motor through a gearbox by means of bush-pin couplings.
The unloading bombhole 4 consists of two radially bent doors with welded plates and stiffeners. The leaves are attached to the shafts using levers. The opening and closing of the bomb bay doors is performed using pneumatic cylinders of the bomb bay 5 pneumatic drive, which, by means of levers and key connections, rotate the flaps around the axes of the shafts installed in the bearing assemblies at the required angle of rotation corresponding to the positions: open and closed. The bomb bay support device consists of locks located on the shaft, which lock the bomb bay from possible opening during product mixing. The locks work synchronously and are set in motion by means of a pneumatic cylinder, the rod of which is extended to the stop in its original state when the doors are closed.
The leaves work as follows. In the initial position, the rods of the pneumatic cylinders are pushed in to the stop - the flaps are closed. At the command of the control system, the pneumatic valve switches, the rod of the pneumatic cylinder of the back-up device moves in, turning the locks and releasing the leaf 1. After that, the rod of the pneumatic cylinder of the leaf 1 drive is extended to the stop, opening this leaf, then the rod of the pneumatic cylinder of the leaf 2 drive, opening the leaf 2. After unloading the mixer the shutters are closed in the reverse order. The backing device has adjustments to prevent poor closing of the flaps in the event of product sticking.
