We are offering subject to being unsold and according to our General Conditions of Sale the following:
(budget quotation)
Attached you will find our offer about our recycling plant for car and truck tyres without rims. The output capacity of this plant is approx. 1,8 t/h, final granulate size is < 4 mm. Not included in this price are the costs for engineering, transport, mechanical and electrical installation, we are not able to estimate this costs in this early state. It also depends on the country where the plant should be installed.
Following values in weight % could be reached after the cleaning process:
- Separation of stones etc.: < 0,1
- Separation of FE: < 0,05
- Separation of textile: < 0,1
We are able to offer according to our delivery and business condition as following:
Plant description:
The plant featured in the quotation serves to recover rubber granulate from car and truck tires for high quality recycling of the granulate. An environment-friendly procedure of hot grinding has been selected for ecological reasons. The aim is to obtain clean granulate measuring <1 mm resp. 1-4 mm. The granulate will be separated in three groups, we recommend to dispose the size < 0,25 mm as this fraction is mainly sand:
- product I 0,25 – 0,8 mm (suggestion)
- product II 0,8 – 1,8 mm (suggestion)
- product III 1,8 – 4,0 mm (suggestion)
The whole plant is divided into four parts:
- Pre-shredding
- Granulation
- Grinding
- Sieving and cleaning
The pre-shredding section includes an efficient working rotor shear and a disk sieve with recovery of oversized granulate. The rotor shear consists of a very high-powered drive and is specially designed for shredding old tires. This machine has an extremely robust design and has been used successfully all over the world since 1992 for shredding of tires. The possibility of replacing the complete blade shafts at once results in the short stand-still periods for this machine.
The tires will be thrown in the hopper serving the cutter module, which shreds the tires. A conveyor belt brings the shredded material to a disk sieve. Pieces larger than 200 x 200 mm are separated out and returned to the rotor shear. Another conveyor belt brings smaller pieces to a tip. From here the tire pieces can be conveyed to the granulating part.
This part of the plant is to be erected outside. The advantage of this is that the "dirty" part of the plant resulting from the tires frequently being full of sand and water, is kept outside the production building.
A wheel loader brings the hand-sized tire pieces from the tip to an automatic bunker. The tire pieces are conveyed to the granulating and grinding sections. This part of the plant consists primarily of two successive, efficient granulators and two parallel working cutting mills. The first granulator is equipped with a sieve with 22 mm holes to expose the steel fraction as far as possible. The second granulator has a 15 mm sieve.
After granulation, the metallic fraction is separated out by a magnetic separator and conveyed directly into a container erected outside. The first granulator is larger and stronger than the second because it has to perform most of the shredding work, and the second granulator has to deal with less metal.
The state-of-the-art granulators have been rated specially for tire granulation, integrating all the experience bomatic has gathered in the production of shredding machines. The heart of the granulator is the rotor shaft, consisting of individual parts rather than one single piece. This results in a slim rotor whose rotation energy can be braked more easily in case of any incidents. Individual rotor brackets are pushed onto a shaft and then screwed together. The blades are screwed to the rotor brackets. In the event of any damage, individual rotor brackets can be replaced rather than having to dismantle the whole shaft. Other advantages include among others a sliding clutch to separate the motor/shaft and spherical roller bearing located outside the cutting chamber. The cutting module is hydraulically hinged to guarantee fast access to the blades and to provide added safety.
After the second granulation and another metal separation stage, the material is conveyed into a sieve machine where parts smaller than 4 mm are already sieved out to relieve the load on the following mill. The rest is conveyed into a cutting mill with 4 mm sieve where it is grinded.
For ecological reasons, every granulator and the cutting mills are equipped with extraction systems with an output of 5,000 m³/h. This keeps the surroundings practically dust-free, and also cools the machines at the same time. The quoted filtration system is supplied in a pressure capsule. This dust extraction system produces cleaned air corresponding to the regulations in the German Clean Air Act.
The material is sucked out of the mill into another bunker where it is conveyed in dosed quantities via an elevator and through a drum magnet where once again the tiniest steel particles are separated out of the product flow. The sieve machine mounted on rubber anti-vibration pads separates the product flow into three fractions (textiles, granulate 0,25 – 4 mm, > 0,25). Another elevator then conveys the granulate to another sieve machine to separate the granulate in final size fraction. From here each size will be transported to the separation tables to separate minerals out of the granulate. The next processing stage consists of further textile separation which separates out the remaining fluff fraction from the granulate. Finally the product passes another vibration sieve and is filled in big bags.
Both the granulating machine and the cleaning machine are equipped with an efficient dust extraction system for extraction and filtration of the air in the areas with dust development.
The corresponding control systems in the central switchboard are monitored by a SIEMENS system to guarantee safe operation of the plant.
In brief, it can be said that this plant is environment-friendly; the hot grinding process does not use any chemicals and the whole plant produces no pollution of the air, water or soil.
