Rolling distance adjustable roller flour mill

Abstract

The invention discloses a rolling distance adjustable roller flour mill. The rolling distance adjustable roller flour mill comprises a lifting device and a carrier plate. The upper end of the carrierplate is fixedly connected to a casing. The upper end of the casing is fixedly connected to a feeding port. The inner wall of the casing is provided with a first sliding slot. A first sliding block isslidably connected to the interior of the first sliding slot. The side of the first sliding block is provided with a groove. A first nut is fixedly connected to the interior of the groove. The innerwall of the casing is fixedly connected to a first motor. An output shaft of the first motor is fixedly connected to a first threaded rod. The first threaded rod fits to the first nut. The inner wall,symmetrical with the first sliding slot, of the casing is provided with a second sliding slot. A second sliding block is slidably connected to the interior of the second sliding slot. The rolling distance adjustable roller flour mill realizes rolling distance adjustment, can produce powder with different particle sizes, and utilizes a tooth plate to replace teeth of a round roller so that disassembly and replacement are convenient.

Description

technical field [0001] The invention relates to the technical field of roller mills, in particular to a roller mill with adjustable rolling distance. Background technique [0002] Roller mill is one of the oldest crushing equipment. It has a simple structure and is still used in cement, silicate and other chemical industries. Mills are widely used in metallurgy, building materials, chemicals, mines and other fields. The grinding process of materials and the normal operation of the roller mill depend on the degree of wear of the roller skin in many aspects. Only when the round roller is in good condition can it obtain higher production capacity and discharge qualified product particle size. Therefore, It is necessary to understand the factors affecting the wear of the roller skin, and to be familiar with the problems that should be paid attention to in the use and operation, to regularly check the wear of the round roller and the teeth on the round roller, and to repair and r...

AI Technical Summary

Problems solved by technology

At present, the rolling distance between the two rollers of the commonly used roller mill cannot be adjusted, and it cannot grind materials with different diameters and produce powder products with different particle sizes. Moreover, the teeth on the round rollers are welded and fixed at present. It is not easy to dismantle and replace after wear and tear, which greatly reduces the work efficiency. The cost of replacing the round roller as a whole is high, resulting in waste. If it is not replaced, the grinding effect will be affected
