Differences in the device of the 37 kW sawdust granulator

Sawdust granulator protection 37 kW

Model history (add-on):

  • cooling system;
  • compatibility with other equipment;
  • block of rollers (4-3 pcs.);
  • control panel;
  • conical rollers.

Clients repeatedly asked us to make a sawdust granulator of increased power, but Artmash specialists had to spend almost 2 years on fulfilling the request.

During this period, the initial design underwent dozens of major and minor changes, so that in the end users received productive, reliable and easy to maintain equipment.

Thanks to checks in real production conditions, we were able to eliminate all the shortcomings that appear during the long-term non-stop operation of the granulator.

Granulator 37 kW, first version

Differences in the device of the granulator of sawdust 37 kW

First of all, the gearbox attracts attention. It is implemented in the form of a hypoid gear with a ground tooth, a large gear ratio and a large torque.

Granulator reducer 37 kW

Features:

Tapered roller bearings with a minimum inner race diameter. Traditionally, we use proven ZKL products. This selection of bearings helped to completely eliminate axial and radial play.
The tooth module in hypoid gear - 10. This size leaves a large margin of safety for bending of the part. This significantly increases the life of the gearbox.
The gearbox is equipped with an oil lubrication and cooling system, which also works to extend the life of the moving parts and bearings, as well as the main gearbox pair.
Bearing with barrel-shaped rollers and a brass cage for extra-large axial loads. Bearings of this type have shown their effectiveness in reducing the main loads on the granulator when we used them in 22 kW models. For a 37 kW granulator, a larger and more powerful option was chosen.

37 kW sawdust granulator rollers

Another important difference is the four-roller mechanism (usually we use only one pair). The rollers are at different distances from the central shaft. Two of them are shifted to the outer perimeter of the matrix, therefore, they push the raw materials through only half of the holes. Thus, the load is distributed evenly and all the details of the moving units last longer.

Roller bearings are protected by machined labyrinths and rubber cuffs, so the raw materials do not clog inside. This simplifies equipment maintenance.

37 kW sawdust granulator protection

Artmash products are always supplied with several levels of protection. In this case, to prevent mechanical overload, our proprietary clutch with minor modifications was used. It begins to slip when the rated motor current rises by only 20%. This fully guarantees that stones or bolts that have fallen into the hopper will not damage the equipment.

37 kW sawdust granulator coupling

In addition to mechanical, electrical protection is also provided: soft start of the engine and UBZ 301 unit in the control cabinet.

It blocks the engine starting or stops the motor in such cases:

  • poor voltage (phase voltage imbalance, surges, alternation disturbances, etc.);
  • damage inside the engine, insulation failure;
  • damage to the supply cable;
  • unacceptably low insulation level on the housing;
  • ground fault of the stator winding during operation.

Model history

A month after the product entered the catalog, three 37 kW granulators have already been received by customers and are operating in Ukraine, as well as abroad. Performance benchmarks have been fully confirmed.

Pellet quality on the pellet mill 37 kW

Our specialists kept in touch with the owners of this model and went several times to check the equipment in continuous operation. As a result, we have developed an optimal service plan for the product, as well as made a number of improvements.

The most notable change was the conversion of the forced lubrication system. All the necessary parts were placed in the pellet mill housing, while providing convenient maintenance. The current modification of the 37 kW pellet granulator has become noticeably more compact than the original version.

Clients often supplement the pellet lines of "Artmash" with additional equipment that is not in our catalog: wood shredders, dryers, etc.
At one of the enterprises in the Kiev region, we saw how all the products function together. This is what the next video is about.

Due to the popularity of this model, we began to make pelletizing lines in which two pelletizers of 37 kW operate simultaneously. For this purpose, we have developed a metering auger with a 3 cubic meter hopper and a more powerful cooling complex.

Two granulators, 37 kW each

Starting from the summer of 2022, pellet mills with a 37 kW motor began to be equipped with three rollers instead of four, as in the original version. This decision made it possible to make the load on the rollers more even, which is safer for the entire structure and helps to reduce wear on consumables. Changes were made in such a way as to maintain the high performance of the granulator.

3 rollers for granulator 37 kW

In the spring of 2023, the GPP-37 model and its aft counterpart (GKP-37) received new control panels. The cabinet has increased in size, and the block of buttons and alarms is located on the upper inclined panel (instead of the vertical panel in the previous version). In addition, handles were installed for convenient transfer of the control cabinet when moving the granulator.

Updated granulators GKP-37 and GPP-37

Granulator control panel 37 kW

Starting from January 2024, all granulators of the GPP-37 and GKP-37 models will be equipped with conical rollers.

Granulator roller block 37 kW with conical shells

This form of shells made it possible to:

✅ Increase the productivity of the granulator by 20-30%.
✅ Increase the resource of videos by 2-2.5 times.
✅ Reduce the frequency of matrix replacement by half.
✅ Save electricity by improving energy efficiency.
✅ Reduce the load on the working units of the granulator.

How exactly the design of the rollers made it possible to achieve such results, see in the video.

The current basic modification of the granulator and other equipment can always be specified on the product page.
