Description
The Unimax UM3300 tub grinder stands out as a top – tier and high – productivity crusher, designed with remarkable versatility. It is particularly well – suited for handling diverse batches of straw crushing tasks or wood crushing operations. One of its distinct advantages is its mobility, allowing for seamless and flexible movement during field operations, which significantly enhances its usability in different work environments.
This robust machine is engineered with an eye – catching 1.8 – meter tub diameter and a 3.3 – meter tub opening. These dimensions not only contribute to its large – capacity processing ability but also enable it to handle a substantial volume of materials at once. Equipped with a powerful Weichai 430HP engine, the Unimax UM3300 adopts a direct – drive mode. This design ensures that the machine can efficiently convert any biomass raw materials into debris with a high level of safety. Whether it’s tough wooden logs or voluminous straw, this crusher can break them down with ease. The resulting debris can then be effectively utilized as biomass energy, playing a crucial role in promoting sustainable energy development and resource recycling in the biomass energy sector.

Features
- Wide range of materials
It can crush various biomass, especially waste wood, tree roots, tree stumps, branches, building templates, board skin, cotton stalks, corn stalks, straw, stalks, etc.
- Strong crushing ability
The blasde roller is constructed from silicon-manganese spring steel for exceptional wear resistance and durability. The holding blade plate utilizes manganese steel plate material, demonstrating high resistance to deformation, impact, and wear. Reduce user maintenance costs while delivering powerful crushing force.
- Controllable crushed material size
For example, a biomass power plant may need to burn straw, or waste wood, or branches. The boiler requires the length of the straw to be 6-10 cm, while the size of the wood and branches is 5-8 cm or smaller. The output size is determined by hole diameter of screen, which can be customized according to needs.
- High production efficiency
Adopting direct drive technology, high transmission efficiency and extremely fast crushing speed, it can crush 20-70 tons of debris per hour.
- Dual control system
There is dual control method: control panel and remote control. Automatic control for the full set mechanism including feeding system, discharging system, emergency stop, reverse system and etc. Effective control distance of the remote controller is 80m.Highly protect the personal safety.
Easy maintenance
The hydraulic lift device can lift the inlet system at a large angle when the machine needs maintenance. The rotor will be exposed for easy work. Reduce labor costs and no need for a crane copperation.
Intelligent reversal system
Automatically monitor the operation. When the load is too large, the hopper will rotate in the reverse direction, so there is no need to worry about the problem of material jam.
- Optional power type and loading method
Loading methods are divided into crawler type, traction type, vehicle-mounted type, which can be selected according to working condition, and the power source we provide electric motors and diesel engines for option.
Power system
Diesel engine type
The diesel engine is fully hydraulically controlled and is suitable for outdoor operations. It has good trafficability and is easy to move.
Electric type
Electric models are usually placed indoors and cannot be moved at will, but they have low cost and are easy to maintain.
Crushing system
Blade type
the blade is more suitable for crushing tree branches and logs.
Hammer type
the hammer can be used to crush wood with nails such as building templates
Mobility system
Crawler type
Remote control crawler self-propelled, easy to move, maximum moving speed 2km/h
Traction type
Can be towed by trucks, loaders, excavators
Vehicle-mounted type
Can be fixed on a truck or on the ground
FAQs about tub grinders
The tub grinder has two types of blade and hammer on the rotor, the hammer can be used to crush wood with nails such as building templates, and the blade is more suitable for crushing waste wood, tree roots, tree stumps, branches, building templates, board skin, cotton stalks, corn stalks, straw, stalks, etc.
Both Unimax horizontal and tub grinders excel at processing wood waste into saleable products. Choosing between a horizontal grinder and a tub grinder depends on your specific needs, including the types of materials you need to process, desired output size and consistency, mobility requirements, space availability, and budget considerations. Horizontal grinders allow for continuous feeding of long and straight material, while tub grinders are ideal at processing bulky and irregularly shaped materials like whole trees, stumps, brush, and demolition debris.
