Vertical mill machine for mineral powder

Abstract

The invention discloses a vertical mill machine for mineral powder, and belongs to the technical field of mining industry machining. The vertical mill machine comprises a bottom plate and a main force assembly fixedly connected to the outer wall of the top of the middle of the bottom plate, wherein three auxiliary assemblies arranged circumferentially are arranged at the top of the bottom plate, and each auxiliary assembly comprises a base fixedly connected to the outer wall of the top of the bottom plate and a support fixedly connected to the outer wall of the top of the base. According to the vertical mill machine for the mineral powder, the auxiliary assemblies are arranged to match the main force assembly such that grinding hammers can be driven to go deep into a material grinding area, and meanwhile, the three grinding hammers are circumferentially arranged, the contact area between materials and the grinding hammers can be increased, and the grinding efficiency is improved; and moreover, the end surfaces of the original positions of driving hammers are tangent to the outer walls of the grinding hammers such that ground materials can be prevented from entering the grinding hammers, and a middle frame has rotating capability by means of rotation of a clamping frame, such that the angles of the grinding hammers are adjustable, and meanwhile, the grinding hammers are connected with a sliding cylinder and can rotate, the sliding cylinder can move in multiple directions, and the feeding distances of the grinding hammers can be adjusted, and angle adjustment is matched.

Description

technical field [0001] The invention relates to a vertical mill device, in particular to a mineral powder vertical mill, which belongs to the technical field of mining processing. Background technique [0002] Mineral powder vertical mill is a kind of powder grinding equipment, which is widely used in building materials, chemical industry, metallurgy and many other fields. It is used to grind raw materials into powder. It directly affects the activity of mineral powder. [0003] The vertical mill needs the cooperation between the grinding disc and the hammer. The hammer of the existing vertical mill can only be adjusted in angle, and a single angle adjustment cannot satisfy the two functions of the hammer extension and rotation, so the angle adjustment cannot make the hammer have the More efficient auxiliary effects. [0004] How to develop a mineral powder vertical mill is an urgent problem to be solved at present. Contents of the invention [0005] The main purpose of...
