Vibrating Grate
The vibrating grate is an accessory for the hopper designed to prevent access to the machine’s danger zone, as required by Regulatory Standard NR12 – Occupational Safety with Machines and Equipment.
Dujua uses the concept of fixed protection, ensuring the health and physical integrity of workers.
The equipment is developed based on NBR NM-ISO 13853 Machine Safety – Safe Distances, to prevent access to danger zones by lower limbs, staying refreshed on official technical standards in force or applicable international standards. Apart from its primary function, which is employee safety, the vibrating grate also serves to prevent larger particles, stones and foreign materials from entering the Hopper and damaging it.

Receiving and Unitizing Table
The receiving and unitizing table is a piece of equipment designed to receive logs, combining various types of loads for conveyance purposes.
The material travels by means of drag chains, moving it and gradually feeding the chopping system.

Hopper Cover
The Hopper Cover is an accessory designed to prevent access to the machine's danger zone when biomass reception is not taking place, as required by Regulatory Standard NR12 - Safety at Work in Machinery and Equipment. Its activation is done through a pneumatic system, which opens the Coverage giving access to the unloading of fuel (biomass) in the Hopper, with sound and visual warnings, and demarcated area, observing the guidelines and safety procedures for unloading, according to technical standards applicable official or international standards, safeguarding the protection of health and physical integrity of workers.
In addition to the main “safety” function, it also keeps the biomass free from weather conditions such as rain, for example, which tends to increase the moisture content of the biomass stored in the receiving hopper.

Auger Hopper
The auger hopper is a piece of equipment designed for receiving, holding and subsequent unloading/dispensing a wide variety of biomass types to the conveyance system, in a continuous manner that is adjustable to the industrial flow feeding process. The material is moved by means of helical spirals (threads).
This equipment can be installed underground, level 0 (pit), to be fed by dump trucks and mobile bottoms, and it can also be installed above ground level to be fed by wheel loaders.

Cleated Drag Hopper
The cleated drag hopper is a piece of equipment designed for receiving, holding and subsequent unloading/dispensing a wide variety of biomass types to the conveyance system, in a continuous manner that is adjustable to the industrial flow feeding process.
Unlike other hoppers, biomass is conveyed via cleats, thus enabling the movement of materials with greater resistance to flowing, such as sugarcane bagasse.
This particularity is the equipment’s distinction, as the same biomass will not have the same efficiency in other hoppers. This equipment can be installed underground, level 0 (pit), to be fed by dump trucks and mobile bottoms, and it can also be installed above ground level to be fed by wheel loaders.

Cleated Link Hopper
The cleated link hopper is a piece of equipment designed for receiving, holding and subsequent unloading/dispensing a wide variety of biomass types to the conveyance system, in a continuous manner that is adjustable to the industrial flow feeding process.
Movement occurs through drag chains, thus enabling the movement of materials with larger particle size, which are not tolerated in an auger hopper, such as briquettes.
This equipment can be installed underground, level 0 (pit), to be fed by dump trucks and mobile bottoms, and it can also be installed above ground level to be fed by wheel loaders.
