Grinding raw materials
Grinding raw materials is one of the more energy-consuming processes in the production of feed. Its task is to bring the raw material to the required particle sizes. This is especially important in the case of animal feed, because too large particles cause nutritional losses and too small leads to diseases of the digestive and respiratory systems.
Hammer mills in the TESTMER offer
Testmer designs and supplies hammer mills lines based on the following devices:
- hammer mill vertical RB-P or horizontal RB-H – as the main milling device,
- DS screw feeders – ensuring proper feeding of the material,
- WMS magnetic separators, aspiration devices – to eliminate unwanted metal waste in the raw material and to ensure raw material purity and reduce dust formation
The Hammer Mill lines are each time adapted to the needs of customers in terms of performance, required grinding, adapted to the raw material used, acceptable dimensions etc.
Hammer Mills RB-P and RB-H have been designed for grinding cereal grains, animal feeds, feed components and other similar materials. In RB-P Hammer Mills, the motor drives the direct rotor of the Hammer Mill. The Hammer Mill can be equipped with an electric motor with power from 11 to 110 kW. In models RB-P45 – 110 it is possible to use a 2-speed engine that allows to obtain the required grinding for various raw materials. Higher speed allows to obtain smaller fractions (e.g. feed for pigs), slower speeds guarantee the quality for poultry. In addition, all Hammer Mills are ready to work with the inverter. Pneumatic or electric opening interlock as well as mechanical or pneumatic sieve replacement system were used as safety equipment.
To ensure the highest efficiency, shredders are delivered with an IE3 engine as standard, in accordance with the requirements of the IEC 60034-30 standard.
On request, the engine and equipment of the Hammer Mill is delivered in ATEX version.
Basic parameters of hammer mills
Output Capacity [t/h] *
* – Output capacity was achieved for wheat grain and 4 mm sieves. It may vary depending on the density of the material, humidity and its mechanical parameters.
The feeders offered in the milling lines ensure even dosing of raw material to the hammer mill. The capacity of the feeder is smoothly regulated by a frequency converter. The feeder has a large inspection door that allows cleaning the inside of the feeder and a air filter.
The dimensions of the feeders are adapted to the size and performance of the hammer mills they will work with.
The magnetic separator is an effective device that does not require external enery
The capacity of the separator is determined by its diameter.
The basic parameters of magnetic separators for animal feed are presented below:
Flow rate [t/h] *
* – The flow rate is indicative for wheat grain. It may vary depending on the density of the material, humidity and its mechanical parameters.
We manufacture separators based on proven and durable magnetic components
Separators and dust filter equipment
The TESTMER offer includes the following devices used in comminution lines:
- stone or coarse sand separators,
- patron dust filters with self cleaning, which ensure effective dust reduction and improved efficiency,
- special tanks under the hammer mills to improve the reception of milled materialPlease you to familiarize yourself with the entire TESTMER offer.
