Daisy Screen for Tyres
The daisy screen is an evolution of the original disk screens and it is used specifically for separating tyre rubber based on the size.
Description
The daisy screen is composed of a series of screening shafts, held by a roust frame to which are welded a series of disks having a special “daisy” shape, variable in accordance with the type of material to be processed.
The screen is located at the outlet of the primary shredding stage and it results in separation of smaller piece sizes. The screen is installed at the outlet from the primary shredding stage, where it separates smaller pieces from larger ones, discharging the screened material onto a conveyor belt that returns it to the shredder to create a continuous flow such that only the under screen piece size, decided beforehand, will progress to the next shredding cycle.
Conversely, larger pieces are returned to the shredder by means of the daisy screen and conveyor, thus creating a continuous cycle.
Technical specifications
- Chain transmission between drive shaft and idle shafts
- Robust support structure

Disk screen
Disk screens are suitable for separation of large quantities of pre-shredded materials such as industrial waste, bulky waste, and biomass. They guarantee high throughput and sizing precision, the ability to carry heavy “foreign” materials and excellent wear resistance.
- The disks are designed with a triangular shape to facilitate separation between heavy and light materials
- The shape of the smooth disks allows rapid cleaning, because the shafts can be easily reached with high pressure jets
- Any material that becomes wrapped around the shaft can be rapidly removed by cutting, since the build-up is easily accessible thanks to the shape of the disks
Rotary Screen
The rotary screen is a system for separating material of predetermined piece size.
Thanks to their special construction design, these machines provide high throughputs and good sizing precision, the ability to transport heavy “foreign” materials, and excellent wear resistance.
- Robust screen support structure made of tubular members, complete with inspection gangway on both sides and access ladder
- Under screen collection hopper and over screen feeding hopper
- Structure composed of HEB girders and tubular members to support the screen and the belt
- Robust arc welded cylindrical structure with bolt-on grids having different perforation sizes based on separation requirements.
Vibrating screen
The vibrating screen exploits undulatory and shaking motion to separate the material from the powder/chips present in the feedstock, which is distributed uniformly over the entire surface of the vibrating screen for more effective separation in the subsequent stages.
- Robust frame in arc-welded tubular members
- Arc- welded trough resting on anti-vibration mounts
- Removable perforated sheet steel panels over the entire length, fixed to the conveyor trough
- Open Style
- Screening table in carbon steel
