The invention discloses an adjustable
pulverizer, and relates to the field of
machining equipment. The adjustable
pulverizer comprises a shell and an outer
barrel. The outer
barrel is movably arranged in the shell and cannot rotate. The inner surface of the outer
barrel is in the shape of a funnel. An elastic device is arranged between the inlet end of the outer barrel and the outer barrel. Bolts are arranged at the outlet end of the outer barrel and arranged on the shell in a penetrating mode. The outer ends of the bolts extend out of the shell, and sleeved with nuts. A conical
grinding roller matched with the outer barrel is further mounted in the outer barrel. A material channel is formed between the conical
grinding roller and the outer barrel. A material inlet and a material outlet communicating with the material channel are formed in the shell. A drive device is further arranged on and connected with the conical
grinding roller. By adoption of the adjustable
pulverizer, the width of the material channel can be effectively adjusted, the structure is simple, the pulverizing effect is good, and the pulverizing efficiency is high.
