ZSL-400
ZSL-400

Batch operated horizontal scraping-blade mixer ZSL-400 is designed for mixing of compound feed components after batch dosing. Size of individual mixing components should be in the range of 0,1 to 3,0 mm. Mixer can be applied at the animal feed production plants and for production of enrichment mixtures.


There is also N-ZSL-400 model designed for mixing of food concentrates or premixes. Mixer details, which contact with mixing products, are made of stainless steel.

Structure and Functioning


Mixer consists of the following elements:

body - 1;

rotor - 2;

drive - 3;

bomb door - 4;

bomb door pneumatic drive - 5;

bomb door lock against opening - 6.


Body-1 is represented by steel welded construction of semi-cylindrical shape. Windows closed with the covers are designed in the side walls of mixer body. Covers are interlocked with electric motor limit switchers and designed for repair works, visual inspection and periodic cleaning of mixer from the inside by scraping or pneumatic tools.


DO NOT turn off the limit switches on the covers during operating and maintaining the mixer. DO NOT continue to operate the mixer in case of limit switches failure.


Rotor-2 is represented by shaft with 4 paddles (scrapers). Blades are installed with special angles that ensure intensive mixing of loading product. Rotor shaft is supported by bearings installed on the mixer body.


Drive-3 provides specified rotor speed from the electric motor through reduction unit.


Unloading bomb door-4 consists of shutter bent along the radius with welded blades and strengthening ribs. Shutter is fixed by levers on the shaft. Bomb door shutter opening and closing is provided by pneumatic cylinder of bomb door pneumatic drive-5, which, by means of levers and key connections, rotates shutter about axis of the shaft installed in the bearing blocks to the required rotation angle, which corresponds to the position: open and closed.


Bomb door lock against opening consists of the bolt lock, which prevent bomb door opening during product mixing. Lock is driven by pneumatic cylinder, which rod is pushed to the stop in initial condition, when shutter is closed. Shutter operation concept is as follows. Pneumatic cylinder rod is pushed to the stop in the initial condition – shutter is closed. On the command of control system, pneumatic distributor is switched, rod of the lock pneumatic cylinder is shut, opening the bolt lock and releasing the shutter 1. Then stock of the shutter drive pneumatic cylinder is pushed to the stop, opening the shutter. After mixer unloading, closing of the shutter is occurred in reverse order.


Operation concept of the mixer is as follows: ingredients entering to the mixing bin are storing up until a portion/level is reached, then dosed components are manually loaded (short loading time prevents delamination of components), in the mixer body, components under rotation of the rotor are subjected to intensive back mixing by paddles. On expiration of mixing time, bomb doors open and resulting mixture is directed to the discharge point from the body. Unloading control is carried out manually or using automation/computer.
