Granulator

Appointment

The granulator press is designed to produce granules from dry raw materials by pressing them with pressing rollers through the holes of the matrix.

Raw materials: grass, straw, beet pulp.

The crushed and crushed raw materials are transferred to the receiving hopper of the granulator, where granules are formed. The crushed herb is steamed in the mixer and enters the pressing unit. Working parts of the camera – These are a rotating ring die and press rolls. The raw material enters the wedge between the inner surface of the matrix and the roller, pressure is created, and the raw material passes through the hole of the matrix (die). They come out from the outside of the matrix and are cut with a static knife (for granules: 6-8 mm).

Characteristic

• Modifications of press granulators differ in the number of revolutions and power of the installed electric motors; the matrices differ from each other in the size of the holes (diameter and length) and thickness. The relationship between the diameter and length of the channel determines the power with which the matrix acts on the product and the amount of energy spent on granulation.

The relationship between the diameter and length of the channel determines the power with which the matrix acts on the product and the amount of energy spent on granulation.
• The humidity of the material supplied to the granulator should be within 10-12%.
• The granulator press must be operated in a class -IIa production room at an ambient temperature of +10 to +35 °C and a relative air humidity of up to 80% at a temperature of +25 °C, equipped with supply and exhaust ventilation.
• The granulator consists of a hopper, a gearbox with a drive and a pressing unit. The granulator hopper ensures a uniform supply of ground biomass for granulation. To prevent material from hanging in the hopper, a turner is installed.
  The hopper consists of a body (1), a turner (2), dispensers for feeding granulators (3), a ladder and a service platform (4).

DO NOT ALLOW THE BUNKER TO OVERFILL!!!, this will lead to clogging of the pneumatic transport system

• The granulator's pressing unit is designed to produce granules by pressing a pre-prepared product with a pressing roller through the radial holes of the annular matrix.
• The productivity of the pellet press and the quality of the pellets can be increased by adding steam. By increasing the amount of added steam from 1% to 4%, productivity doubles.

Components of a granulator press

Dispenser

The essence of dosing is to regulate the speed of rotation of the shaft and, consequently, change the volume of product supplied to the mixer.

1. dispenser body;
2. unloading point;
3. removable cover;
4. dispenser shaft;
5. adjustable blades;
6. bearings;
7. bush-pin coupling.

Mixer

Serves for mixing the product after it has been heated and moistened with steam and water, while simultaneously moving the product from the receiving chute to the unloading chute along the axis of the mixer.

1. mixer body;
2. lid;
3. mixer shaft;
4. replaceable blades;
5. shaft drive;
6. cover lock;
7. blocking

Press

Designed to produce granules from a moistened product by pressing it with a pressing roller through the radial holes of an annular matrix rotating around a horizontal axis.

1. press body;
2. pressing unit;
3. drive unit;
4. turnbuckles;
5. press cover;
6. loading node;
7. unit for unloading granules;
8. lubrication unit;
9. traverse for installing matrices;
10. V-belt transmissions.

Specifications

The principle of operation

The principle of operation of the granulator press is as follows: the processed product is fed through a doser with an adjustable drive into the mixer, where it is brought to the required humidity and temperature by supplying steam and water, and through an inlet device with an anti-overload valve is fed into a rotating matrix.< /p>

Two adjustable pressing rollers located inside the matrix force the product through the holes in the matrix. The granules squeezed out of the holes collide with a stationary knife, break off and are removed from the press.

Advantages

• The front door is made of stainless steel and equipped with an overflow and control valve.
• The press frame is made entirely of cast iron, which supports the entire structure and guarantees maximum stability and smooth operation of the press.
• The matrix connection is reinforced with stainless steel and pressed onto the shaft at four points, which guarantees low matrix wear.
• To protect the press from overloads, there is a safety pin that ensures the shaft remains stationary relative to the press body.
• To protect against belt slipping, a speed control sensor is installed, which turns off the press drive when the pulley rotation speed changes.
• Normal operation of the press is ensured by an automatic centralized lubrication system.
• The safety of the overflow valve is ensured by a cylinder actuated by an overload relay to prevent the press from blocking.
• A large magnet built into the front door prevents metal particles from getting onto the rollers.
• The press is equipped with two pressing rollers, the bearings are protected by labyrinth seals.
• Automatic lubrication system of the granulator press.
