Morphology
The meaning 'the number of occurrences within one minute' is directly and transparently derived from combining 'count' (a tally) with 'per' (indicating rate) and 'minute' (sixty seconds). This is a standard, cross-linguistically common rate construction, so a B1 learner who knows the constituent words would readily infer the MWE's meaning.
Etymology
Count per minute comes from the simple action of counting how many times something happens in one minute. If you count beats or clicks per minute, you find the 'number of events' in that time, so the phrase means the number measured in one minute.
