Cyclic smashing system and control method

Abstract

The invention discloses a cyclic smashing system, and belongs to the technical field of cyclic smashing. The cyclic smashing system comprises a smashing screening unit and a weighing unit; the smashing screening unit comprises a smashing mechanism and a classifying screen communicating with a discharging outlet of the smashing mechanism; the classifying screen is configured to screen unqualified materials and qualified materials out of materials smashed by the smashing mechanism; the weighing unit communicates with the classifying screen and comprises a weighing mechanism and a proportional valve which communicate in sequence; the weighing mechanism is used for receiving and weighing the unqualified materials; the proportional valve is configured to be openable so that the unqualified materials can enter the smashing mechanism again after passing through the weighing mechanism, or configured to be closable so that all the unqualified materials can enter the weighing mechanism to be weighed. The proportional valve is opened, the unqualified materials enter the smashing mechanism again, material cyclic smashing is achieved, the proportional valve is closed, the residual unqualified materials enter the weighing mechanism to be weighed, and traceability of materials of the same batch is achieved.

Description

technical field [0001] The invention relates to the technical field of circulating crushing, in particular to a circulating crushing system and a control method. Background technique [0002] In the production of food and pharmaceutical industries, the circulation crushing system directly determines the quality and output of products, and an efficient circulation crushing system is conducive to the rapid and healthy development of the food and pharmaceutical industries. [0003] The grading sieve of the current circulating crushing system can screen out qualified materials, and send unqualified materials back into the crushing mechanism for circular crushing until the crushing operation of the same batch of materials is completed. However, with the improvement of intelligence and automation of the cyclic crushing system, it is necessary to make statistics and forecasts on the output and waste of the same batch of materials, so as to realize the traceability of materials and ...

AI Technical Summary

Problems solved by technology

At the same time, the screen in the crushing mechanism is prone to damage, causing un-crushed materials or large-grained materials to directly enter the circulating crushing process, which increases the crushing difficulty and workload of the circulating crushing system, and reduces the efficiency of the crushing operation of the circulating crushing system. Destroy the traceability of the same batch of materials
