Product Description
Mobile horizontal grinder crawler Type is a dedicated equipment for biomass power plant for fuel reserve and MDF plant. Raw materials mainly consist of all kinds of trees, undersized log, timber felling residues (such as branch, twig, etc.), wood pallet, wood building template, and wood processing residues ( such as slab, batten, log core, building templates, etc.) and non-wood raw materials (such as waste of flax, reed, bamboo ,maize straw, cotton stalk, etc.).
Based on our company's decades of experience in manufacturing of drum wood chipper, the machine is elaborately designed according to raw materials characteristics and end users' requirement for material particle size, and has the feature of wide raw material adaptability, high production capacity, reasonable structure, easy operation, high safety and reliability, easy transporting and convenient maintenance. Besides, we has got many patents for core components. It's the most ideal biomass chipper worldwide at present.
Product Structure
Machine details
The Mobile horizontal grinder crawler Type is mainly composed of deisel engine, chassis, dead knife base, dead knife, chipping rod, rotor, main shaft, hammer or blade, upper feeding mechanism, below feeding mechanism, feeding device, discharge device, hydraulic system, control system and mobile device.
Product Features
1) Rotor rotation speed adjustable. According to the customer's specific requirements, the machine can be modified, such as adjusting the corresponding parts to change the rotation speed of the rotor, to meet the different requirements of customers on discharging granularity and production capacity.
2) The material of the main shaft is 40Cr heat-treated and quenched, and the machining process is independently completed by our company's machining center to ensure product quality and machine stability.
The rotor roller is fixed with the main shaft locking sleeve, the blade seat is made of 45 steel, and the blade clamp is made of cast steel, which is sturdy and durable.
3) All rotor will go through strict Dynamic balance test to guarantee running stability after finish manufacturing and assembling.
4) Integrated processing of cast steel parts for bottom blade assembly
5) Forced auto feeding system. Start the oil pump, oil cylinder piston extend-retract, swing device rises or falls, then the upper feed roller adapt to the nature of feedstock automatically. This function enables the machine can adapt to wide range raw material and the feed process is more smooth. We got the patent for it.
6) Easy maintenance. Thanks to the hydraulic system, it is easy and convenient to open the machine cover to check or replace the cutter, screen mesh and so on.
7) Chain conveyor. The feeding chain conveyor is made of high manganese steel with the thickness 10mm, which is a typical anti-wear steel, cast organization is austenite and carbide. Via the water toughening treatment, the surface would be rapidly hardening and that make its internal remains the good toughness and deformability under the condition of strong impact and extrusion and the hardening layer with good wear resistance. These characteristics determine that the service life can be up to 22000 hours, which is better than the traditional belt's 2000 hours. In addition, the traditional belt' s with small friction coefficient which will cause the feed speed to be slow and not smooth, but the chain type solved all the above questions.
8) Perfect chain conveyor length. The length of the chain conveyor is matched with the machine running, which can achieve the best machine performance.
9) Dual control, One is fixed electrical cabinet and the other is remote control, that makes the operation more safe and convenient.
10) Feeding adjusting. During running, oil is supplied to the hydraulic motor by a gear pump, and the electromagnetic directional valve enables the feeding roller to complete the feed in and reverse process. The manual speed control valve can adjust the speed of the feed roller.
11) Overload protection. The circuit has an overload protection device, which automatically cuts off the circuit when overloaded.
12) Pulley secured by inner hole locking device. Easy to assemble and disassemble. No the traditional violent assemble and disassemble. Protect the main motor. This makes easy to maintain the main and prolong the life span of the main motor.
13) Core components processed as a complete part.
14) Machine frame components are processed by laser cutting machine.
