Introduction

According to the classification of GB/T 15706-2012, this document belongs to Class C standard. This document is particularly relevant to the following stakeholders involved in machinery safety. Machine manufacturers;- Health and Safety Agency. - Other stakeholders affected by the level of machinery safety are. Machine users;- The owner of the machine;- Service providers;- Consumer (when the machine is intended for use by a consumer). - All of the above stakeholders may participate in the drafting of this document. The machines involved and the range of hazards, hazardous situations and hazardous events covered are given in the scope of this document. When the requirements of this document differ from those in Category A or Category B standards, for machines designed and manufactured in accordance with this document, this document Requirements in this document take precedence over requirements in other standards. Rubber and plastic crushing machinery mainly consists of blade crusher, strand pelletizer, shredder and pelletizer, so GB/T 25936 "Rubber and Plastic Crushing Machinery" is divided into the following four parts according to the equipment classification. Part 1.Safety requirements for blade crushers. The purpose is to specify the requirements for crushing rubber and plastic materials with blades in the crushing chamber. The safety requirements for the design and manufacture of blade crushers are to crush the material until it can pass through the screen holes of appropriate specifications and enter the discharge area. requirements and provide instructions for safe use of the machine. Part 2.Safety requirements for strand pelletizers. The purpose is to specify the requirements for cutting rubber and plastic strip materials into regular shapes in the cutting chamber. The safety requirements for the design and manufacture of the strand pelletizer are determined, and relevant instructions for the safe use of the machine are given. Part 3.Safety requirements for shredders. The purpose is to specify the requirements for shredders that are used to shred rubber and plastic materials on one or more slow-moving shafts. The safety requirements for the design and manufacture of shredders for shredding materials are set out, and relevant instructions for the safe use of the machine are given. Part 4.Safety requirements for pelletizers. The purpose is to specify the requirements for pelletizing waste thermoplastics to change their shape, size and flow in a closed room. Safety requirements for the design and manufacture of dynamic agglomerators are specified, and instructions for safe use of the machines are given. Rubber and plastic crushing machinery Part 3.Safety requirements for shredders

1 Scope
