Selecting the right crusher for your operations
For example, if a company can sell 500,000 tonnes per year, its crushers need to produce just short of 42,000 tonnes each month. If the crusher is set up to run three days a week (about 13 days a month) for eight hours a day, the operation will require a machine capable of processing 400 tph. {{image3-A:L-w:350}}

Force Calculator F = ma
What is the force required to accelerate an object with a mass of 20 kg from stationary to 3 m/s 2? F = m * a. F = 20 kg * 3 m/s 2. F = 60 N. Newtons are a derived unit, equal to 1 kg-m/s². In other words, a single Newton is equal to the force needed to accelerate one kilogram one meter per second squared. Further Reading
