The BLUE SHARK Hammer Mill Shredder

Product catalog summary

Specifications and Components:
The document describes a machine equipped with a large hopper for loading materials and a removable cradle. It includes a proximity sensor to detect the hydraulic pusher position and guide wheels for the hydraulic pusher. The machine body is shielded with Hardox 400 sheets to withstand strong shocks and aid in material crushing. A hydraulic bulkhead facilitates fast unloading of unmilled heavy blocks. The system is supported by dampers to minimize vibrations, complying with safety standards.

Operational Procedures:
The machine features hydraulic pins and cylinders for opening the cap of the upper grids and removing the cradle of the lower grid, allowing for easy maintenance and grid changes. The rotor, equipped with four rows of hammers, is designed for durability and efficiency, with lubrication provided by an oil circuit. The PLC and radio remote control system allow for precise control of the rotor's speed and position, optimizing performance and safety.

Movable Rotor Functionality:
The HP3000 model includes a movable rotor, which can be adjusted manually or automatically to handle uncrushed pieces, release jams, and set material size. This feature enhances operational flexibility and efficiency.

Support Structure and Safety:
The machine is mounted on a robust support structure with auxiliary components like a vibrating surface and magnetic drum. Safety features include catwalks and railings. The structure houses the engine and reduction unit, designed to absorb impacts and vibrations, protecting the reduction unit from damage.

Hydrodynamic Coupling and Transmission:
The hydrodynamic coupling system offers advantages such as no-load engine start-up, gentle loading, and overload absorption. The innovative component sequence protects the reduction unit from rotor impacts, enhancing durability.

Additional Features:
The document briefly mentions ferrous metals and inert materials separation and a zig-zag mechanism, though details are limited.

OPENING THE CAP OF THE UPPER GRIDS The two upper sections are closed and locked by means of hydraulic pins, driven by proportional solenoid valves controlled via a push-button panel and supplied by the control unit. Hydraulic cylinders open and lock these pins. When they are operated, the cylinders push the cap upwards so that you can safely and easily work on the grids. REF. 1 REMOVING THE CRADLE OF THE LOWER GRID The cradle, which houses the lower grid, is also closed by hydraulic pins. When the pins are removed, the two hydraulic cylinders push the cradle on two guides external to the mill...

SHAFT AND HAMMERS The four rows of three hammers (total 12) are hinged onto the 7 discs of the rotor by 4 steel shafts and steel supports designed and manufactured by Zato. The bearings with double row of rollers are lubricated by an oil circuit supplied by a hydraulic control unit, filters and pre-heating resistances. This means that, when it is very cold, two auxiliary sensors check that oil flows properly and triggers the alarm system if necessary. Steel spacers separate the discs on the rotor and the entire assembly is fixed with bolts to ensure better elasticity and longer life. Each disc...

SUPPORT STRUCTURE (optional) The solid structure on which the machine is fitted has sturdy electro-welded beams. Inside, all the auxiliary components of the system are found: vibrating surface, magnetic drum, first unloading belt, hydraulic unit, power station. It has catwalks and safety railings. The structure (not including the auxiliary components) weighs about 15 tons. A second structure (about 9 tons) houses the engine and the reduction unit/hydrodynamic coupling unit. It also has catwalks and safety railings. MOVABLE ROTOR As standard, HP3000 models are equipped with a movable rotor (fitted...

Reduction unit and hydraulic coupling Inside the steel electro-welded box you will find a pair of gears, the body of the hydrodynamic coupling, hub, input shaft, output shaft and hub, oil tank, fuel pump, the coupling, lubrication pump, bearings, two speed detectors (input and output), oil level detector and filters, oil pressure sensor and alarms, and air heat exchanger. Drainable hydraulic couplings facilitate disconnecting the engine from the loading. This results in remarkable advantages: - No-load engine start-up - Gentle loading start-up - Overload absorption - Impact on reduction unit...
