Problems solved by technology
If only one-step crushing method is used, the separation of crushed paper and gypsum is not complete, and it cannot be directly used for recycling in production. It is practical to add grinding and screening equipment to subsequent raw material production equipment.

Embodiment Construction
[0034] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.
[0035] The invention provides a method for recycling and processing gypsum boards, such as figure 1 As shown, the following steps may be included:
[0036] s1: Pass the gypsum board through the primary crushing device for coarse crushing, and break the gypsum board into pieces of gypsum board with a diameter of less than 100mm;
[0037]In the specific operation of the present invention, the first stage crushing device can adopt a roller crusher or a shearing crusher; When the gypsum board fragments with a diameter of less than 100mm are formed, the gypsum board fragments ar...

Abstract
The invention discloses a recovery and treatment method and device of a gypsum plaster board. The recovery and treatment method comprises the following steps of carrying out coarse crushing treatment on a gypsum plaster board by a first-stage breaker, feeding the broken gypsum plaster board into a second-stage breaker, carrying out fine crushing treatment, feeding the gypsum plaster board particles into a third-stage breaker, carrying out rolling treatment, feeding the gypsum plaster board powder into a separator and carrying out separation. The recovery and treatment device comprises a first conveying unit, a first-stage fragmentation treatment unit, a second conveying unit, a second-stage fragmentation treatment unit, a third conveying unit, a third-stage fragmentation treatment unit and a screening separation unit, and the above units are orderly connected. The recovery and treatment method and device can be used in the technical field of gypsum plaster board recovery. The recovery and treatment method and device realize effective recovery of the gypsum plaster board and improve a gypsum plaster board comprehensive utilization value.
Description
technical field [0001] The invention relates to the technology of gypsum boards, in particular to a recycling method and device for gypsum boards. Background technique [0002] At present, gypsum board enterprises at home and abroad are taking corresponding measures to recycle waste paper-faced gypsum boards to achieve the purpose of reducing environmental pollution and waste of resources. Among them, there are two main recycling methods for paper-faced gypsum boards: one is to burn the waste gypsum boards to remove the outer protective paper, and then crush the waste gypsum boards for reuse, but this method cannot The outer protective paper is used, and burning will cause pollution; the other is to crush the gypsum board, and then separate the gypsum core from the protective paper, and then reuse it to make gypsum board, which not only reduces environmental pollution, but also Can reduce production cost. [0003] Correspondingly, aiming at the above-mentioned recycling me...
