Machine Purpose
A container with walking floor is a modern storage and feeding device designed for uniform and controlled dispensing of various types of bulk materials. The device is used for handling materials such as sawdust, wood chips, beet and corn pulp, or alternative fuels like RDF. The construction of the walking floor container enables stable and continuous material feeding to technological receivers, ensuring high reliability and process repeatability.

Operating Principle
The feeding mechanism of the walking floor container works as follows.
An electric motor through a combined reduction gearbox rotates the drive shaft. Steel sprocket wheels are mounted on the shaft, whose profile during rotation forces the movement of chains connected with scrapers. Material is moved to the discharge point. In the rear part of the hopper is a tension shaft with two bushed guide wheels, and chain tension adjustment is done using two tensioning screws.

Technical Specification
A walking floor container is a welded massive steel structure with a dense arrangement of load-bearing profiles. Depending on technological requirements, internal surfaces can be finished with stainless steel sheet (1.4301) or galvanized sheet.

The main part of each hopper consists of four welded steel wall frames, floor frames (in quantities depending on the number of material-moving mechanism sections), and connecting (assembly) frames welded to the floor frames.

Model ZS-4 is the smallest version with 4 m³ capacity, compact dimensions and 0.75 kW drive power, equipped with one feeding section – designed for small installations. ZS-6 offers 6 m³ capacity, greater length and 1.1 kW power, still with one section, making it an intermediate solution for small loads. ZS-11 is a medium model with 11 m³ capacity, larger dimensions and 1.1 kW power, suitable for more intensive work while maintaining one feeding section.

Models ZS-17 and ZS-30 are designed for larger applications, having 17 and 30 m³ capacity respectively, two feeding sections, and increased drive power of 2 × 1.5 kW and 2 × 2.2 kW respectively, ensuring more efficient material transport.

The largest model, ZS-90, offers as much as 90 m³ capacity, four feeding sections and 2 × 3 kW drive, making it adapted for work in large industrial and agricultural installations with high capacity.

All walking floor container models have a chain breaking load of 9000 kg.​

Other Applications
Due to construction versatility, walking floor containers can handle various bulk materials in the chemical, pharmaceutical, construction, or recycling industries.

Machine Purpose
A screw conveyor, also called a screw feeder or auger, is a device designed for efficient transport of bulk materials over short and medium distances. The basic purpose of the machine is to move raw materials horizontally, at an angle, or vertically, making it a universal transport solution. Besides transport, screw conveyors also perform product dosing functions in technological processes, material mixing, and sludge transport. Thanks to closed construction, transported material can be isolated from the environment, which is particularly important in industries requiring sterility and safety.​

Operating Principle
The operating principle is based on rotary motion of the screw, whose drive is realized by a motor with gearbox. Inside the housing is a screw shaft on which a spiral surface called screw ribbon is wound. As the shaft rotates, screw flights with special spiral shape catch material and move it along the trough housing.​ The process is intuitive. Material in the form of grain, flour, seeds, gravel, or sand is introduced to the feeder through a hopper. Then the rotating shaft causes transported material to move to the outlet point. This mechanism is based on the Archimedes screw principle, guaranteeing stable and predictable operation regardless of transported material type.​

Technical Specification
A screw conveyor consists of the following key elements:​
Working trough is the main housing, usually U-shaped or tubular
Feeding hopper is the material entry point
Screw shaft is a tube connected with wound spiral, i.e., screw ribbon
Nozzles are material inlet and outlet
Drive is motor with gearbox
Bearings are shaft support
Covers are in closed versions

Construction Materials
Screw conveyors are made of high-quality materials ensuring durability and resistance:
Carbon steel is grades C1020, C1040, C1045, C4140 are most commonly used
Stainless steel is 304 and 316 ideal for humid and corrosive environments
Wear-resistant steels for applications requiring abrasion resistance
Monel and other special alloys for demanding work conditions
Plastics for specialized applications

Applications in Individual Industries
Agricultural Industry
On farms, screw conveyors serve to transport grain, seeds, and feed. Devices are used for loading, unloading, and grain transport between machines, as well as for animal feed dosing. They can also transport other bulk materials such as mineral fertilizers or feed semi-finished products.​

Wood and Biomass Industry
Screw conveyors play a key role in sawdust and chip transport. In furniture factories and sawmills, devices transport bulk wood waste to fuel silos or for further processing. In paper mills, screws transport wood material from the yard to the digester where it's processed into pulp. In renewable energy, wood biomass is transported to heating boilers where it serves as fuel for steam and electric power production.​

Energy
In biomass-fired power and heating plants, screw conveyors transport wood fuel from warehouses to furnaces, and also transport ash from furnaces to waste containers. These systems work continuously and reliably, which is a necessary condition for strategic energy equipment.​

Chemical Industry
Devices transport chemical raw materials and preparations, especially in powder and granule form. Closed construction ensures operator safety and prevents environmental contamination.​

Construction Industry
Conveyors transport cement, sand, gravel, and other bulk materials at construction sites and in cement plants and grinding facilities. Devices speed up the loading and unloading process and automate deliveries to mixers.​

Recycling and Waste Management
In recycling plants and wastewater treatment installations, screw conveyors transport sludge, waste, and materials returning to production. They are particularly useful for sticky, wet, and difficult-to-transport materials.​

Machine Purpose
Scraper conveyors, also called drag conveyors, are transport devices designed for continuous transfer of bulk materials inside a closed trough. The main task of the machine is efficient transport of various raw materials and products over medium to long distances, both horizontally and at an angle, even vertically.​
Devices work especially well when transporting materials with higher moisture content, irregular granulation, and in demanding work conditions, ensuring system tightness and limiting dust emission. The possibility of loading and unloading at any point along the route is an additional advantage of this design.​

Operating Principle
A scraper conveyor works based on the following mechanism.
Action structure:
An electric or hydraulic motor drives sprockets that move two endless chains connected with scrapers
Chains along with scrapers move inside the conveyor trough
Scrapers push material along the trough bottom, moving it away from walls and shifting it toward the outlet
Chain speed is regulated depending on transported material type and required capacity parameters, which also enables material dosing.​

Technical Specification
Scraper conveyors are made of materials ensuring high durability and reliability. Chain components, i.e., pins, bushings, bolts, axles, are made of special steels with heat treatment to achieve required hardness and strength.​

Construction Materials
Carbon steel as basic construction material
Acid-resistant steel for applications requiring corrosion resistance
Sliding plates or basalt lining as friction and wear reduction elements
Chains of fully welded steel, heat-treated
Replaceable slides and guide rollers reducing wear
