technical field

The utility model relates to an automatic production line for powder crushing and processing, in particular to a grinder and sieve machine capable of preventing screen blockage.

Background technique

In the traditional crushing and grinding operation, the crushing and screening methods have a long process and a lot of equipment, and the materials are added manually, and the workload is heavy. Due to the large particle size of the traditional grinding and sieving machine, when passing through the screen, it is often blocked in the mesh, which reduces the working efficiency of the screen and affects production.

Utility model content

The purpose of the utility model is to provide a ball mill with high working efficiency and anti-clogging screen.

The utility model is achieved through the following technical solutions:

A grinding and sieving machine for preventing screen blockage, which includes a frame, a motor is arranged in the middle of one end of the frame, a speed reducer is arranged above the motor, and the motor and the speed reducer are connected by a V-belt; A ball mill cylinder is arranged above the frame, one end of the ball mill cylinder is connected with the reducer, the other end of the ball mill cylinder is provided with a hopper, and a discharge hopper is provided below the ball mill cylinder, and the discharge hopper is fixed on the frame, A screen is arranged inside the hopper, and the screen is located on one side of the ball mill cylinder and fixed on the screen frame; on the wall of the ball mill cylinder, there are evenly arranged several outlets near the end of the hopper, and several outlets are evenly arranged on the other end. There is a material return port, and a sweeping brush is arranged on the outer wall of the ball mill cylinder, and the sweeping brush includes a brush handle and bristles.

Further, the brush handle is integrally made of plastic.

Further, the bristles are nylon wires or steel wires.

Further, the screen is a semi-cylindrical stainless steel mesh or nylon mesh coaxial with the barrel wall of the ball mill.

Further, the feeding hopper is a cylindrical body combined with a round table.

Further, the lower part of the hopper is two conical barrels with cylindrical outlets.

The beneficial effects of the utility model are: on the basis of the original equipment, the utility model is provided with multiple rows of sweeping brushes on the cylinder wall of the ball mill cylinder. During the rotation of the ball mill cylinder, the brushes will also rotate along with the bristles. Sweep through the sieve holes, sweep down the materials stuck in the middle of the mesh, increase the working area of the sieve, improve the working efficiency of the drying net, not only greatly improve the transmission of powder and the grinding rate, but also prolong the service life of the sieve , saving costs and meeting production needs.

detailed description

As shown in accompanying drawing 1-4, a kind of anti-screen blockage ball milling equipment, it comprises frame 1, and the middle position of one end of described frame 1 is provided with a platform, and motor 2 is fixed on the platform, and described motor 2 The platform above is provided with a reducer 4, and the motor 2 and the reducer 4 are provided with pulleys, and the motor 2 and the reducer 4 are connected by a V-belt 3; the top of the frame 1 is provided with a ball mill cylinder 5, the One end of the ball mill cylinder 5 is connected to the reducer 4, and a bearing seat is arranged between the ball mill cylinder 5 and the reducer 4. The bearing seat is placed on the frame 1, and the other end of the ball mill cylinder 5 is provided with a hopper 7, which is a cylinder The cylinder body combined with the round table, the ball mill cylinder 5 and the hopper 7 are provided with a bearing seat, and the bearing seat is placed on the frame 1. The bottom of the ball mill 5 is provided with a discharge hopper 8, and the lower part of the discharge hopper is two tapered cylinders with cylindrical outlets. The discharge hopper 8 is fixed on the frame 1, and the inside of the discharge hopper 8 is provided with a screen 6, a screen 6 It is a stainless steel mesh or nylon mesh with an arc-shaped surface coaxial with the wall of the ball mill cylinder 5. The screen 6 is located on one side of the ball mill cylinder 5 and is fixed on the screen frame 61; Four rows of sweeping brushes 51 are arranged, and the sweeping brushes 51 are made of integrally formed brush handles 52 and bristles 53, the brush handles 52 are made of plastics, and the bristles 53 are nylon wires or steel wires.

The product enters the inside of the ball mill barrel 5 from the hopper 7 for grinding, and the ground product enters the screen 6 through the discharge port 9 for screening, and the small-sized product enters the discharge hopper 8 through the screen 6 for the next step Operation, and some products can be blocked in the mesh of screen cloth 6, and sweep material brush 51 can sweep product down from mesh this moment.
