Wood crushing machine

Wood chipper equipment machinery with drum type, intended for crushing pieces of wood, pulp, furniture wastes, chipboard, etc. Professional solution for a pellet factory with a capacity of over 1 ton/h. The chipper produces quality calibrated chips with a capacity of up to 2 tons per hour and the chips is with a size of 5 – 10 mm and up to 5 tons per hour with chips sized of 30-50 mm.

Chips size is determined by the size of the sieve and feed rate speed of the material to the blades. The minimum space from the rollers to the knives allows you to crush wood cuttings with a length of 20 cm. At the customer’s request, feed rate and sieve size can be set when the machine is made. The four working knives allow the machine to chop any type of wood (round, flat, etc.) up to 20 cm in diameter and up to 40 cm wide. This allows each customer to maximize the effect of the crushing process and to obtain the most suitable chips size.

The machine is also equipped with:

1. Shock system

Designed to prevent overloading of the motor. Upon overloading, the system stops delivering raw material to the blades. After the sieve has been cleared, the feed is restored.

2. Adjustment of the Chips size and crushing productivity

In case the customer needs chips of different sizes, a material feed inverter is installed. When changing speed rate of feeding raw material to blades, the chips size and the crushing productivity change. When installing this system, the customer has the option of choosing chip size and crushing productivity by himself. It can get a smaller flow with a shorter and smaller chips and can get a maximum flow with a bigger chips.
