Hammer grinders are used to coarsely crush a material to the desired grain size, which depends on the density and the size of the holes in the sieve used. The size of the sieve is adapted to the needs of the customer, the desired grain size and the type of material to be crushed. We manufacture robust and high-quality hammer grinders that are suitable for composting. They are suitable for crushing or grinding flowers, fruit, vegetables and annual branches, but are not suitable for thicker branches.
