摘要： A sheet manufacturing apparatus includes an impeller mill, a first sieve, a first belt, a rotary body, a second sieve, a second belt, and a heating roller. The impeller mill defibrates a raw material containing fiber and discharges a defibrated material. The first sieve screens the defibrated material by causing the defibrated material to pass through a first net. The defibrated material passing through the first sieve is deposited on the first belt to form a web. The rotary body has a protrusion radially protruded from a rotation center and divides the web by rotation to form a subdivided body. The second sieve refines the subdivided body by causing the subdivided body to pass through the second net to form a web. The refined subdivided body is deposited on the second belt to form a web. The heating roller heats the web from the second belt to form a sheet.
