Mesh is the US sieve number: the higher the number, the smaller the opening. A 4–10 mesh product passes a No. 4 sieve (4.76 mm) and is held on a No. 10 sieve (2.00 mm), so its particles are about 2–5 mm.
A plus sign means retained on that sieve (+4 mesh is larger than 4.76 mm); a minus sign means passing it (−30 mesh is smaller than 0.595 mm).
