Mills are supplied fully assembled and ready to work. Roll setting is quick and simple with over centre lever and eight different locking positions - offering a full range of crush levels on all crops. Feed rate is easily adjusted using the sliding gate, referring to the ammeter provided to optimisemotor loading. Roll scrapers can be locked into engaged position - or can be used intermittently as required. The spring rolls apply optimum pressure to allow flat rolling whilst still providing security when stones etc pass through the machine (the roll gap increases momentarily).
